CSFA (Certified Surgical First Assistant) Exam — Questions and Answers

Question 1: During a procedure, a scrubbed team member's glove is punctured. What is the immediate priority?

Apply a sterile glove over the punctured glove
Notify the surgeon and change gloves promptly (Correct answer)
Continue if the puncture is on a finger not used for handling instruments
Use the other hand exclusively for the remainder of the case

Correct answer: Notify the surgeon and change gloves promptly

A punctured glove must be changed promptly after notifying the surgeon to maintain aseptic technique and patient safety.

Question 2: Following a thyroidectomy, a patient develops perioral numbness, tingling of the fingertips, and a positive Chvostek's sign. These findings are MOST consistent with:

Hypocalcemia due to parathyroid gland injury (Correct answer)
Hypomagnesemia from excessive diuresis
Hypocalcemia due to thyroid hormone deficiency
Hyperkalemia from blood transfusion

Correct answer: Hypocalcemia due to parathyroid gland injury

Inadvertent parathyroid removal or devascularization during thyroidectomy causes hypocalcemia, which presents with perioral numbness, tetany, and a positive Chvostek's sign.

Question 3: During an open cholecystectomy, the surgical first assistant must identify Calot's triangle. Which THREE structures define this anatomical triangle?

Common hepatic duct, liver edge, and cystic duct (Correct answer)
Cystic duct, cystic artery, and common hepatic duct
Cystic duct, portal vein, and hepatic duct
Cystic duct, common bile duct, and liver edge

Correct answer: Common hepatic duct, liver edge, and cystic duct

Calot's triangle is bounded by the cystic duct inferiorly, the common hepatic duct medially, and the inferior edge of the liver superiorly, with the cystic artery coursing within it.

Question 4: The surgical skin preparation (prep) area should extend well beyond the anticipated incision site in order to:

Provide a sterile margin if incision boundaries need to change during surgery (Correct answer)
Allow easy placement of electrosurgical return electrode pads
Improve visualization of all anatomical landmarks
Enable continuous skin temperature monitoring

Correct answer: Provide a sterile margin if incision boundaries need to change during surgery

Prepping a wide area beyond the planned incision provides a margin of sterility in case the incision must be extended or additional access sites are needed unexpectedly.

Question 5: The Aldrete score used for PACU discharge decisions evaluates which five parameters?

Pain, nausea, blood pressure, consciousness, and urine output
Respiration, circulation, temperature, activity, and surgical site
Activity, pain, respiration, temperature, and oxygen saturation
Activity, respiration, circulation, consciousness, and oxygen saturation (Correct answer)

Correct answer: Activity, respiration, circulation, consciousness, and oxygen saturation

The modified Aldrete score assesses activity level, respiratory effort, circulation (BP), consciousness, and oxygen saturation to determine PACU discharge readiness.

Question 6: Which of the following is considered a 'passive' or 'mechanical' topical hemostatic agent that works by absorbing blood and providing a physical matrix for clot formation?

Tranexamic Acid (TXA)
Epinephrine solution
Topical Thrombin
Regenerated Oxidized Cellulose (Correct answer)

Correct answer: Regenerated Oxidized Cellulose

Regenerated oxidized cellulose (e.g., Surgicel) is a passive hemostatic agent. It does not contain active clotting factors but instead provides a physical scaffold that absorbs blood and promotes platelet aggregation, facilitating the natural clotting cascade. Topical thrombin is an active biological agent, TXA is an antifibrinolytic, and epinephrine is a vasoconstrictor.

Question 7: A patient on chronic warfarin therapy requires emergent surgery. Which product provides the FASTEST reversal of warfarin's anticoagulant effect?

Vitamin K (oral)
4-factor prothrombin complex concentrate (PCC) (Correct answer)
Fresh frozen plasma
Platelet transfusion

Correct answer: 4-factor prothrombin complex concentrate (PCC)

4-factor PCC provides immediate replenishment of all vitamin K-dependent clotting factors, offering faster reversal than FFP or oral vitamin K.

Question 8: What arteries can be separated during a AAA resection and then reanastomosed to the graft?

ent
renal (Correct answer)
lumbar
hepatic

Correct answer: renal

During an Abdominal Aortic Aneurysm (AAA) resection, the diseased segment of the aorta is replaced with a graft. If the renal arteries originate from the aneurysmal portion, they must be carefully detached and then reanastomosed (reconnected) to the new graft. This crucial step ensures continued blood flow to the kidneys, preserving their function after the repair.

Question 9: Which medication is used intraoperatively to treat acute intraoperative anaphylaxis as the DRUG OF CHOICE?

Albuterol
Diphenhydramine
Epinephrine (Correct answer)
Hydrocortisone

Correct answer: Epinephrine

Epinephrine is the drug of choice for anaphylaxis; it reverses bronchospasm, vasodilation, and urticaria through alpha and beta adrenergic stimulation.

Question 10: A patient in the Post-Anesthesia Care Unit (PACU), 30 minutes after a major abdominal surgery under general anesthesia, develops severe muscle rigidity, tachycardia, hyperthermia (104°F / 40°C), and a rapidly increasing end-tidal CO2. What is the most likely diagnosis that requires immediate intervention?

Thyroid Storm
Malignant Hyperthermia (MH) (Correct answer)
Sepsis
Neuroleptic Malignant Syndrome

Correct answer: Malignant Hyperthermia (MH)

This specific combination of symptoms—hyperthermia, severe muscle rigidity, tachycardia, and hypercarbia—occurring shortly after administration of triggering general anesthetic agents is the classic presentation of a Malignant Hyperthermia crisis. [8, 12] Immediate treatment with dantrolene is critical to prevent life-threatening complications. [3, 17] While other conditions can cause hyperthermia, the rapid onset of muscle rigidity is a key differentiator pointing to MH. [12]

Question 11: The pudendal nerve (S2-S4) exits the pelvis through the greater sciatic foramen and re-enters through the lesser sciatic foramen to travel in which canal?

Alcock's canal (Correct answer)
Adductor canal
Obturator canal
Femoral canal

Correct answer: Alcock's canal

The pudendal nerve travels through Alcock's canal (pudendal canal) along the lateral wall of the ischioanal fossa after re-entering through the lesser sciatic foramen.

Question 12: Which volatile anesthetic agent is CONTRAINDICATED in patients with a known or suspected susceptibility to malignant hyperthermia?

Nitrous oxide
Sevoflurane (Correct answer)
Ketamine
Propofol

Correct answer: Sevoflurane

Sevoflurane (and all halogenated volatile agents) can trigger malignant hyperthermia in susceptible patients and must be avoided.

Question 13: Which of the following compounds helps feces travel through the large intestine more easily?

chyme
mucus (Correct answer)
hydrochloric acid
amylase

Correct answer: mucus

The large intestine secretes mucus, which plays a vital role in the smooth passage of feces. This mucus lubricates the intestinal walls, reducing friction and making it easier for the compacted waste material to move through the colon and rectum. It also provides a protective barrier for the intestinal lining against irritation from the fecal matter.

Question 14: Which postoperative electrolyte imbalance is MOST commonly associated with cardiac arrhythmias and is a known risk following prolonged nasogastric suctioning?

Hypokalemia (Correct answer)
Hypernatremia
Hypermagnesemia
Hypocalcemia

Correct answer: Hypokalemia

Prolonged NG suctioning removes gastric fluid rich in potassium and hydrogen ions, leading to hypokalemia and metabolic alkalosis that predispose to arrhythmias.

Question 15: A CSFA is assisting with the closure of a multi-layered abdominal incision. To approximate the fascial layer, which requires high tensile strength and prolonged support for healing, which suture technique is most appropriate?

Pursestring suture
Simple interrupted suture (Correct answer)
Continuous subcuticular suture
Vertical mattress suture

Correct answer: Simple interrupted suture

The simple interrupted suture technique is ideal for closing fascia because each stitch is independent, providing secure closure and high tensile strength across the wound. If one suture breaks, the integrity of the rest of the closure is not compromised. Subcuticular sutures are for skin, vertical mattress sutures are for skin eversion, and pursestring sutures are for closing circular openings.

Question 16: A patient on postoperative day 3 following a colectomy has a distended abdomen, has not passed flatus, and reports nausea with no bowel sounds audible upon auscultation. These findings are most indicative of which postoperative complication?

Mechanical small bowel obstruction
Acute pancreatitis
Anastomotic leak
Postoperative ileus (Correct answer)

Correct answer: Postoperative ileus

Postoperative ileus is a temporary and expected cessation of bowel motility following abdominal surgery. The classic signs include abdominal distention, nausea and vomiting, inability to tolerate an oral diet or pass flatus, and absent or hypoactive bowel sounds. [5, 11, 24] While an anastomotic leak or mechanical obstruction are serious considerations, this clinical picture is the hallmark of a functional postoperative ileus. [14, 22]

Question 17: Which reversal agent is used to antagonize the effects of non-depolarizing neuromuscular blocking agents?

Sugammadex only
Neostigmine (Correct answer)
Naloxone
Flumazenil

Correct answer: Neostigmine

Neostigmine is an acetylcholinesterase inhibitor that reverses non-depolarizing NMBAs by increasing acetylcholine at the neuromuscular junction.

Question 18: During a shoulder arthroscopy performed in the beach chair position, the patient's blood pressure drops significantly. The CSFA and surgical team should be most concerned about which specific position-related complication?

Cerebral hypoperfusion (Correct answer)
Sciatic nerve damage
Brachial plexus injury
Venous thromboembolism

Correct answer: Cerebral hypoperfusion

In the upright beach chair position, a hydrostatic gradient exists between the heart (where a blood pressure cuff is typically placed) and the brain. A normal blood pressure reading at the arm may correspond to a dangerously low perfusion pressure in the brain, leading to cerebral hypoperfusion and potential ischemic injury.

Question 19: Which nerve is at risk during dissection along the medial aspect of the axilla during axillary lymph node dissection?

Musculocutaneous nerve
Long thoracic nerve (Correct answer)
Thoracodorsal nerve
Median nerve

Correct answer: Long thoracic nerve

The long thoracic nerve runs along the serratus anterior on the medial axillary wall and, if injured, causes a winged scapula.

Question 20: Cushing's triad (hypertension, bradycardia, irregular respirations) indicates dangerous elevation of intracranial pressure through compression of which brainstem structure?

Cerebellum
Pons
Medulla oblongata (Correct answer)
Midbrain

Correct answer: Medulla oblongata

Rising ICP compresses the medulla oblongata, stimulating vasopressor and cardiovascular control centers, producing the classic Cushing's triad as a late sign of herniation.

Question 21: During orthopedic surgery, pulsatile lavage irrigation is used primarily to:

Mechanically debride and reduce bacterial counts in the surgical site (Correct answer)
Improve visualization by flooding the field
Sterilize the wound with chemical agents
Accelerate bone healing

Correct answer: Mechanically debride and reduce bacterial counts in the surgical site

Pulsatile lavage uses pressurized fluid to mechanically dislodge debris, necrotic tissue, and bacteria from the wound.

Question 22: During a laparoscopic cholecystectomy, intraoperative cholangiography (IOC) is performed. What is the primary purpose of IOC during this procedure?

To identify common bile duct anatomy and detect unsuspected stones or ductal injuries (Correct answer)
To measure bile duct pressure before transection
To confirm adequate hepatic blood flow postresection
To document cystic duct patency for the pathology report

Correct answer: To identify common bile duct anatomy and detect unsuspected stones or ductal injuries

IOC delineates ductal anatomy in real time, helping prevent bile duct injuries and simultaneously identifying retained common duct stones.

Question 23: During an airborne infection isolation procedure (e.g., TB patient), the surgical team should wear at minimum:

Powered air-purifying respirators (PAPRs) only
N95 respirators fit-tested to each individual (Correct answer)
Standard surgical masks
Double-layered surgical masks

Correct answer: N95 respirators fit-tested to each individual

N95 respirators filter at least 95% of airborne particles and must be fit-tested to the individual user to be effective against Mycobacterium tuberculosis.

Question 24: When assisting with patient positioning for a procedure in the lateral decubitus position, the CSFA must be particularly vigilant to prevent injury to which of the following nerve structures?

The brachial plexus by using an axillary roll and limiting arm abduction. (Correct answer)
The femoral nerve by padding under the knees.
The sciatic nerve by avoiding excessive hip flexion.
The obturator nerve by preventing hyperabduction of the legs.

Correct answer: The brachial plexus by using an axillary roll and limiting arm abduction.

In the lateral position, the dependent shoulder and arm are at risk. An axillary roll is placed just caudal to the axilla (under the chest wall) to prevent compression of the axillary artery and the brachial plexus. Additionally, the non-dependent arm should not be abducted more than 90 degrees to avoid stretching the brachial plexus. The other nerve injuries listed are more commonly associated with different surgical positions, such as lithotomy or supine.

Question 25: When applying sterile gloves using the closed-glove technique, the hands must remain:

Inside the cuffs of the gown throughout the entire gloving process (Correct answer)
Extended beyond the cuffs of the gown before the first glove is applied
At the side until the circulator presents the glove
Bare and visible to ensure accurate placement of the glove

Correct answer: Inside the cuffs of the gown throughout the entire gloving process

In the closed-glove technique, hands remain inside the gown cuffs until gloves are fully applied, preventing ungloved hands from contaminating the sterile gown exterior.

Question 26: A patient develops hypotension immediately after induction with propofol. The BEST initial pharmacological intervention is:

Sodium bicarbonate IV
Phenylephrine or ephedrine IV bolus (Correct answer)
Atropine 2 mg IV
Epinephrine 1 mg IV push

Correct answer: Phenylephrine or ephedrine IV bolus

Phenylephrine (pure vasopressor) or ephedrine (vasopressor + mild inotrope) are first-line agents for propofol-induced hypotension due to vasodilation.

Question 27: What distinguishes a figure-of-eight suture from a simple interrupted suture?

It passes through tissue twice in a crossing pattern, distributing tension over a wider area (Correct answer)
It is placed subcutaneously only
It is tied before placement
It uses absorbable material exclusively

Correct answer: It passes through tissue twice in a crossing pattern, distributing tension over a wider area

A figure-of-eight suture crosses over itself, engaging tissue at two points and distributing closure tension more broadly than a simple interrupted suture.

Question 28: A patient reports feeling a 'pop' and notices a pink watery discharge from their abdominal wound on postoperative day 5. The MOST likely complication is:

Hematoma formation
Normal serosanguineous drainage
Surgical site infection with abscess
Wound dehiscence with evisceration risk (Correct answer)

Correct answer: Wound dehiscence with evisceration risk

A 'popping' sensation followed by salmon-colored (serosanguineous) discharge is a classic presentation of fascial dehiscence requiring immediate wound assessment.

Question 29: Which anatomical structure forms the medial boundary of the femoral triangle and must be protected during femoral artery exposure?

Iliopsoas muscle
Sartorius muscle
Pectineus muscle
Adductor longus muscle (Correct answer)

Correct answer: Adductor longus muscle

The adductor longus muscle forms the medial boundary of the femoral triangle, lateral to the femoral vessels during surgical exposure.

Question 30: When assisting with a free tissue transfer (free flap), the most critical intraoperative parameter the surgical first assistant should help maintain throughout the microsurgical anastomosis is:

High-dose anticoagulation with heparin boluses every 30 minutes
Tight glycemic control with insulin infusion
Adequate systemic perfusion pressure and avoidance of vasopressors (Correct answer)
Patient core temperature below 35°C to reduce metabolic demand

Correct answer: Adequate systemic perfusion pressure and avoidance of vasopressors

Adequate perfusion pressure without vasoconstrictors is essential for free flap survival; vasopressors can cause anastomotic spasm and flap failure.

Question 31: A patient requires a rapid sequence intubation (RSI). The anesthesiologist plans to use succinylcholine. The CSFA should be aware that an absolute contraindication for this depolarizing neuromuscular blocker is a personal or family history of what condition?

Asthma
Diabetes Mellitus
Malignant Hyperthermia (Correct answer)
Hypertension

Correct answer: Malignant Hyperthermia

Succinylcholine is a known and potent trigger for malignant hyperthermia (MH), a rare but life-threatening inherited hypermetabolic disorder of skeletal muscle. Its use is strictly contraindicated in any patient with a personal or family history of MH.

Question 32: During a carotid endarterectomy, injury to which nerve results in hoarseness and difficulty swallowing?

Recurrent laryngeal nerve (Correct answer)
Glossopharyngeal nerve (CN IX)
Hypoglossal nerve (CN XII)
Superior laryngeal nerve

Correct answer: Recurrent laryngeal nerve

The recurrent laryngeal nerve innervates the intrinsic laryngeal muscles, and injury causes ipsilateral vocal cord paralysis with hoarseness.

Question 33: A scrub person notices that a sterile package has a small hole in the outer wrap. The CORRECT action is to:

Inspect the contents under a light and use if visually clean
Use it if the inner wrap is intact
Reinforce the hole with sterile tape and use the item
Consider the item non-sterile and obtain a replacement (Correct answer)

Correct answer: Consider the item non-sterile and obtain a replacement

Package integrity is essential to sterility maintenance; any breach in packaging — even a pinhole — renders the contents non-sterile.

Question 34: During a laparoscopic procedure, the CSFA is controlling the camera. The surgeon repeatedly complains of a poor, unstable image and difficulty with depth perception. Which of the following is the MOST critical skill for the CSFA to improve to resolve this issue?

Maintaining a stable camera hand and anticipating the surgeon's movements. (Correct answer)
Ensuring the light source is at its maximum brightness setting.
Using a 0-degree scope exclusively for better orientation.
Frequently cleaning the laparoscope lens intra-abdominally.

Correct answer: Maintaining a stable camera hand and anticipating the surgeon's movements.

A steady image is crucial for surgeon concentration and performance. The camera operator acts as the surgeon's eyes, and an unstable, shaky image can cause disorientation and frustration. Anticipating the surgeon's next move allows the CSFA to provide the optimal view without constant verbal commands. While lens cleaning, light source intensity, and scope choice are important, a stable hand and proactive navigation are the fundamental skills to address the surgeon's specific complaints of instability and poor depth perception.

Question 35: What is the primary purpose of using a pledget in cardiac surgery?

To identify vessels for ligation
To reinforce sutures in fragile tissue (Correct answer)
To absorb excess irrigation fluid
To mark suture lines

Correct answer: To reinforce sutures in fragile tissue

Pledgets are small felt or Teflon bolsters used to reinforce sutures in friable or thin cardiac tissue to prevent tearing.

Question 36: A Jehovah's Witness patient undergoing surgery has refused blood transfusion even in life-threatening circumstances. The surgical first assistant should:

Proceed with surgery but order blood products to be kept on standby
Contact ethics only after the case is complete
Override the refusal in an emergency as the patient's life takes precedence
Document the refusal, ensure a signed refusal form is in the chart, and inform the surgeon and anesthesia team (Correct answer)

Correct answer: Document the refusal, ensure a signed refusal form is in the chart, and inform the surgeon and anesthesia team

A competent adult's refusal of blood products is legally and ethically binding; the team must document it, inform all providers, and plan bloodless surgical strategies.

Question 37: Which of the following organisms is the most common cause of healthcare-associated surgical site infections?

Pseudomonas aeruginosa
Candida albicans
Escherichia coli
Staphylococcus aureus (Correct answer)

Correct answer: Staphylococcus aureus

Staphylococcus aureus, including MRSA strains, remains the leading cause of SSIs in healthcare settings due to its presence on skin flora.

Question 38: During a splenectomy, the surgeon encounters diffuse, low-pressure oozing from the splenic bed after the organ has been removed. Traditional methods like suture ligation and electrocautery are not practical for this large, raw surface. Which of the following would be an appropriate adjunctive hemostatic technique for the CSFA to prepare?

Irrigating the area with sterile water.
Applying bone wax to the entire surface.
Preparing a topical hemostatic agent, such as oxidized regenerated cellulose. (Correct answer)
Requesting a vascular clamp for aortic cross-clamping.

Correct answer: Preparing a topical hemostatic agent, such as oxidized regenerated cellulose.

Topical hemostatic agents are designed to assist in hemostasis when conventional methods are ineffective or impractical, such as with bleeding from raw surfaces of parenchymal organs like the spleen or liver. Oxidized regenerated cellulose (e.g., Surgicel) is an absorbable agent that provides a matrix for platelet adhesion and clot formation. Bone wax is for bone bleeding, aortic clamping is a major maneuver for massive hemorrhage, and sterile water would cause hemolysis and is not a hemostatic agent.

Question 39: Which intravenous anesthetic agent is preferred for patients with a history of postoperative nausea and vomiting (PONV) due to its antiemetic properties?

Ketamine
Etomidate
Propofol (Correct answer)
Midazolam

Correct answer: Propofol

Propofol has intrinsic antiemetic properties and is associated with lower rates of PONV compared to other induction agents and volatile anesthetics.

Question 40: During an exploratory laparotomy for trauma, the surgical first assistant identifies a grade III liver laceration with active bleeding. The MOST appropriate initial maneuver to control hemorrhage is:

Direct suture ligation of bleeding vessels
Pringle maneuver (occlusion of the hepatoduodenal ligament) (Correct answer)
Immediate hepatic artery ligation
Packing the liver and temporary abdominal closure

Correct answer: Pringle maneuver (occlusion of the hepatoduodenal ligament)

The Pringle maneuver occludes the portal triad (portal vein, hepatic artery, bile duct) by compressing the hepatoduodenal ligament, reducing hepatic inflow and allowing time for definitive hemorrhage control.

Question 41: The thoracic duct terminates by emptying into which venous structure?

Left brachiocephalic vein
Right subclavian vein
Superior vena cava
Left subclavian vein at its junction with the internal jugular vein (Correct answer)

Correct answer: Left subclavian vein at its junction with the internal jugular vein

The thoracic duct empties into the venous system at the junction of the left subclavian and left internal jugular veins (left venous angle).

Question 42: A patient in the Post-Anesthesia Care Unit (PACU) who received a volatile anesthetic and succinylcholine begins to exhibit unexplained tachycardia, muscle rigidity, and a rapid rise in end-tidal CO2. Which of the following is the priority emergency intervention?

Preparing for immediate re-intubation.
Administering a bolus of cooled intravenous fluids.
Administering intravenous dantrolene sodium. (Correct answer)
Applying external cooling blankets and ice packs.

Correct answer: Administering intravenous dantrolene sodium.

The patient's signs and symptoms—tachycardia, muscle rigidity, and hypercarbia following exposure to triggering anesthetic agents—are classic indicators of a malignant hyperthermia (MH) crisis. The definitive and priority treatment is the immediate administration of intravenous dantrolene, a muscle relaxant that directly inhibits calcium release from the sarcoplasmic reticulum, thereby halting the hypermetabolic process. While cooling measures and airway management are crucial supportive therapies, they do not correct the underlying pathophysiology like dantrolene does.

Question 43: What is the primary purpose of performing a surgical site mark preoperatively?

To indicate where the incision will be closed
To identify vascular access sites
To prevent wrong-site surgery (Correct answer)
To guide anesthesia needle placement

Correct answer: To prevent wrong-site surgery

Surgical site marking is a Joint Commission Universal Protocol requirement to prevent wrong-site, wrong-procedure, wrong-person surgery.

Question 44: Which anatomic structure separates the anterior and posterior triangles of the neck and serves as a key landmark during neck dissection?

Omohyoid muscle
Anterior scalene muscle
Sternocleidomastoid muscle (Correct answer)
Platysma muscle

Correct answer: Sternocleidomastoid muscle

The sternocleidomastoid muscle divides the neck into the anterior and posterior triangles and is a central landmark guiding the planes of modified radical neck dissection.

Question 45: A patient undergoes a three-field esophagectomy for esophageal cancer. In the immediate postoperative period, the patient develops significant hoarseness. This complication is most frequently associated with an intraoperative injury to which nerve?

Recurrent laryngeal nerve (Correct answer)
Vagus nerve
Phrenic nerve
Superior laryngeal nerve

Correct answer: Recurrent laryngeal nerve

The recurrent laryngeal nerve (RLN), particularly the left RLN which loops under the aortic arch, is at high risk of injury during the cervical and thoracic dissection of an esophagectomy. The RLN provides motor function to the intrinsic muscles of the larynx; injury results in vocal cord paralysis and subsequent hoarseness.

Question 46: The intrinsic conduction system of the heart enables communication between its muscle fibers.

contract only when they receive a nerve impulse
contract on their own (Correct answer)
receive oxygen from other cells
receive energy from other cells

Correct answer: contract on their own

The intrinsic conduction system of the heart is composed of specialized cardiac muscle cells that possess automaticity, meaning they can generate their own electrical impulses. This inherent ability allows the heart muscle fibers to contract spontaneously and rhythmically without external nervous stimulation. This self-excitation ensures the heart can maintain a consistent beat independently.

Question 47: Which bloodborne pathogen has the HIGHEST risk of transmission following a needlestick injury from an infected patient?

Hepatitis B virus (HBV) (Correct answer)
Hepatitis C virus (HCV)
HIV
Cytomegalovirus (CMV)

Correct answer: Hepatitis B virus (HBV)

Hepatitis B virus has a transmission risk of up to 30% per needlestick from an HBsAg-positive source, significantly higher than HCV (~3%) or HIV (<1%).

Question 48: Which of the following actions violates aseptic technique during surgical draping?

Draping from the incision site outward
Reaching across the unsterile side to adjust a drape (Correct answer)
Holding drapes above waist level during placement
Unfolding drapes away from the sterile field

Correct answer: Reaching across the unsterile side to adjust a drape

Reaching across an unsterile area contaminates the sterile glove and gown, violating aseptic technique.

Question 49: A preoperative patient is found to have a hemoglobin of 7.2 g/dL. Which intervention is the surgeon most likely to order before an elective major abdominal procedure?

Proceed with surgery and transfuse intraoperatively as needed
Order a bone marrow biopsy before any decision
Postpone surgery and treat the anemia preoperatively (Correct answer)
Administer epinephrine and proceed

Correct answer: Postpone surgery and treat the anemia preoperatively

A hemoglobin of 7.2 g/dL indicates significant anemia; elective major surgery is typically deferred until anemia is investigated and corrected.

Question 50: During a femoral hernia repair, which structure forms the medial boundary of the femoral ring and must not be cut unless a corona mortis is present?

Cooper's ligament
Femoral vein
Inguinal ligament
Lacunar (Gimbernat's) ligament (Correct answer)

Correct answer: Lacunar (Gimbernat's) ligament

The lacunar ligament forms the sharp medial boundary of the femoral ring; it is normally incised to reduce an incarcerated femoral hernia but may contain an anomalous obturator artery (corona mortis).

Question 51: To maximize effectiveness in preventing surgical site infections, when should the initial dose of a prophylactic intravenous antibiotic like cefazolin be administered?

Within 60 minutes prior to the surgical incision. (Correct answer)
Within 2 hours after the surgical incision.
In the preoperative holding area, at least 3 hours before surgery.
As the final surgical dressing is being applied.

Correct answer: Within 60 minutes prior to the surgical incision.

To be effective, prophylactic antibiotics must achieve adequate bactericidal concentrations in the serum and tissues by the time the incision is made. The Surgical Care Improvement Project (SCIP) guidelines and best practices recommend administering the first dose of most IV antibiotics within the 60-minute window before the surgical incision. For certain antibiotics with longer infusion times, like vancomycin, administration may begin within 120 minutes.

Question 52: During a posterior fossa craniotomy, which cranial nerve emerges from the pontomedullary junction and is at risk during cerebellopontine angle dissection?

CN XI (accessory)
CN V (trigeminal)
CN VII (facial) (Correct answer)
CN IX (glossopharyngeal)

Correct answer: CN VII (facial)

The facial nerve (CN VII) emerges at the pontomedullary junction and traverses the cerebellopontine angle, making it highly vulnerable during acoustic neuroma surgery.

Question 53: Which muscle forms the floor of the femoral triangle and lies deep to the femoral vessels?

Sartorius
Iliopsoas (Correct answer)
Adductor longus
Pectineus

Correct answer: Iliopsoas

The iliopsoas muscle forms the floor of the lateral portion of the femoral triangle, with the pectineus forming the medial floor.

Question 54: During hip arthroplasty in the lateral decubitus position, injury to which nerve causes foot drop and requires careful padding and positioning?

Common peroneal nerve (Correct answer)
Obturator nerve
Tibial nerve
Femoral nerve

Correct answer: Common peroneal nerve

The common peroneal nerve wraps around the fibular neck and is compressed by positioning devices or traction in lateral decubitus, causing foot drop if injured.

Question 55: During a spinal fusion procedure, the surgical first assistant is asked to apply bone wax. Its primary purpose is:

Promotion of osteogenesis
Fixation of spinal hardware
Mechanical hemostasis of bleeding cancellous bone surfaces (Correct answer)
Antimicrobial coverage of the exposed bone

Correct answer: Mechanical hemostasis of bleeding cancellous bone surfaces

Bone wax physically occludes the haversian canals of cancellous bone to mechanically control bleeding from cut bony surfaces.

Question 56: During an open cholecystectomy, the surgical first assistant identifies Calot's triangle. Which three structures form the boundaries of this triangle?

Cystic artery, hepatoduodenal ligament, and duodenum
Common bile duct, cystic artery, and liver edge
Cystic duct, hepatic artery, and portal vein
Cystic duct, common hepatic duct, and inferior surface of the liver (Correct answer)

Correct answer: Cystic duct, common hepatic duct, and inferior surface of the liver

Calot's triangle is bounded by the cystic duct inferiorly, the common hepatic duct medially, and the inferior surface of the liver superiorly.

Question 57: A patient with known renal failure requires a non-depolarizing neuromuscular blocker. Which agent is SAFEST because it undergoes Hofmann elimination (non-organ-dependent degradation)?

Pancuronium
Cisatracurium (Correct answer)
Rocuronium
Vecuronium

Correct answer: Cisatracurium

Cisatracurium undergoes Hofmann elimination (spontaneous degradation at physiological pH and temperature), making it safe in renal or hepatic failure.

Question 58: During a mastectomy with sentinel lymph node biopsy, the blue-stained lymph node is identified but appears to be in close proximity to the axillary vein. What is the first assistant's primary responsibility at this moment?

Immediately clamp the node and divide it
Place a vessel loop around the axillary vein as a precaution
Provide meticulous retraction and clear visualization to protect the vein during dissection (Correct answer)
Inject additional blue dye to confirm mapping

Correct answer: Provide meticulous retraction and clear visualization to protect the vein during dissection

The first assistant's primary role is to provide optimal retraction and exposure so the surgeon can safely dissect the sentinel node away from the axillary vein.

Question 59: During an open inguinal hernia repair, the surgeon dissects the spermatic cord. The CSFA must be aware that entrapment of a nerve that runs with the cord can lead to chronic postoperative groin pain and numbness of the upper scrotum and medial thigh. Which nerve is most at risk?

Obturator nerve
Lateral femoral cutaneous nerve
Ilioinguinal nerve (Correct answer)
Genitofemoral nerve

Correct answer: Ilioinguinal nerve

The ilioinguinal nerve travels along with the spermatic cord and provides sensation to the skin of the superomedial thigh, the root of the penis, and the upper part of the scrotum (or mons pubis and labia majora in females). It is highly vulnerable to being inadvertently sutured, entrapped in mesh, or directly injured during inguinal hernia repair, making it a primary cause of chronic post-herniorrhaphy pain.

Question 60: Which of the following describes the primary physiological goal of applying and inflating a pneumatic tourniquet on an extremity for a surgical procedure?

To prevent deep vein thrombosis (DVT)
To create a bloodless surgical field (Correct answer)
To decrease postoperative pain sensation
To reduce the patient's systemic metabolic rate

Correct answer: To create a bloodless surgical field

The principal function of a pneumatic tourniquet in surgery is to occlude arterial blood flow to a limb, thereby creating a bloodless or near-bloodless operative field. This significantly improves visualization for the surgeon, increases precision, and reduces intraoperative blood loss.

Question 61: At the conclusion of a procedure, the anesthesiologist needs to reverse the effects of rocuronium. Which of the following drugs works by encapsulating the neuromuscular blocking agent, rendering it inactive?

Atropine
Flumazenil
Sugammadex (Correct answer)
Neostigmine

Correct answer: Sugammadex

Sugammadex is a selective relaxant binding agent that directly encapsulates aminosteroid neuromuscular blockers like rocuronium and vecuronium in a 1:1 ratio, forming a complex that is then cleared by the kidneys. This mechanism allows for rapid and complete reversal at any depth of blockade. Neostigmine is a cholinesterase inhibitor, and flumazenil reverses benzodiazepines.

Question 62: Regarding preoperative hair removal at the surgical site, which method and timing are most consistent with evidence-based guidelines to reduce the risk of surgical site infections (SSIs)?

Hair should always be removed to ensure a clean field.
Shaving with a razor the night before surgery.
Using a depilatory cream 2 hours before surgery.
Using clippers immediately before the procedure, outside the operating room. (Correct answer)

Correct answer: Using clippers immediately before the procedure, outside the operating room.

Guidelines from organizations like AORN recommend that hair should only be removed if it interferes with the procedure. When removal is necessary, using electric clippers is the preferred method as it minimizes skin trauma. This should be done as close to the time of surgery as possible, and preferably outside the sterile operating room to prevent loose hair from contaminating the field.

Question 63: In the immediate postoperative period, which assessment finding would MOST concern the surgical first assistant monitoring a patient after thyroidectomy?

Serosanguineous drainage at the wound site
Mild sore throat from intubation
Hoarseness and stridor with perioral tingling (Correct answer)
Heart rate of 88 bpm

Correct answer: Hoarseness and stridor with perioral tingling

Stridor with hoarseness and perioral tingling after thyroidectomy suggests hypocalcemia from parathyroid injury plus potential airway compromise from hematoma or nerve damage.

Question 64: Which of the following is a crucial role played by the skull?

To protect vital organs like the spinal cord and nose.
To protect vital organs like the brain and carpus.
To protect vital organs like the brain and eyes. (Correct answer)
To protect vital organs like the spinal cord and nose.

Correct answer: To protect vital organs like the brain and eyes.

The skull's primary and most crucial role is to provide robust protection for the delicate and vital organs housed within the head. Specifically, it forms a strong bony casing that safeguards the brain from external trauma and provides a protective structure for sensory organs like the eyes. This protection is essential for neurological function and survival.

Question 65: A patient who is HIV-positive is scheduled for an elective cholecystectomy. Standard Precautions in this case require:

Scheduling the case last of the day to allow extra terminal cleaning time
Placing the patient in airborne isolation and using N95 respirators
Requiring double-gloving for all personnel involved in the case
Treating all blood and body fluids as potentially infectious, same as any other patient (Correct answer)

Correct answer: Treating all blood and body fluids as potentially infectious, same as any other patient

Standard Precautions treat ALL patients' blood and body fluids as potentially infectious regardless of known diagnosis, so care does not change based on HIV status.

Question 66: During a Whipple procedure (pancreaticoduodenectomy), which major vascular structure posterior to the neck of the pancreas must be carefully protected?

Superior mesenteric artery
Splenic artery
Portal vein (Correct answer)
Inferior mesenteric vein

Correct answer: Portal vein

The portal vein lies directly posterior to the neck of the pancreas and is the most critical vascular structure to protect during the pancreatic neck transection in a Whipple procedure.

Question 67: When assisting during an open repair of an abdominal aortic aneurysm, what maneuver is performed to control proximal hemorrhage before clamping the aorta?

Infrarenal aortic compression against the spine (Correct answer)
Rapid packing of the retroperitoneum
Direct finger compression on the aorta at the diaphragm
Femoral artery balloon occlusion

Correct answer: Infrarenal aortic compression against the spine

Infrarenal aortic compression against the lumbar spine controls proximal bleeding temporarily while vascular clamps are applied.

Question 68: Which knot is most appropriate when tying a deep pelvic suture with limited visibility and restricted hand movement?

Instrument tie (Correct answer)
Granny knot
Surgeon's knot
Square knot thrown by hand

Correct answer: Instrument tie

An instrument tie allows precise knot placement in deep, restricted spaces where hand tying is impractical.

Question 69: When assisting with wound closure, the surgical first assistant is asked to perform an interrupted suture technique. What is the primary advantage of interrupted sutures over a continuous running suture?

Reduced risk of wound dehiscence if one suture breaks (Correct answer)
Faster closure time
Easier to remove postoperatively
Less tissue reaction

Correct answer: Reduced risk of wound dehiscence if one suture breaks

Interrupted sutures provide security because if one suture fails, the others maintain wound integrity, whereas a continuous suture failure can cause the entire closure to open.

Question 70: In the OR, the zone considered the area of greatest microbial risk to an open wound is:

Directly over and around the operative site (Correct answer)
The scrub sink area
The substerile room adjacent to the OR
The restricted zone outside the sterile field

Correct answer: Directly over and around the operative site

The area directly over and around the operative site is most critical because airborne or contact contamination here directly threatens the open wound.

Question 71: The CSFA notices the surgical field is oozing excessively. The surgeon requests topical thrombin. Which statement about topical thrombin is CORRECT?

It converts fibrinogen to fibrin at the surgical site (Correct answer)
It must be injected IV to work effectively
It permanently dissolves blood clots
It is safe to inject intravascularly

Correct answer: It converts fibrinogen to fibrin at the surgical site

Topical thrombin converts fibrinogen to fibrin locally, promoting clot formation at the site of bleeding; it must never be injected intravascularly.

Question 72: Postoperative oliguria is defined as urine output less than:

0.1 mL/kg/hr
0.5 mL/kg/hr (Correct answer)
1.5 mL/kg/hr
1.0 mL/kg/hr

Correct answer: 0.5 mL/kg/hr

Oliguria is defined as urine output less than 0.5 mL/kg/hr and indicates potentially inadequate renal perfusion.

Question 73: A CSFA is assisting with an emergency exploratory laparotomy for a perforated duodenal ulcer with established peritonitis. How would this surgical wound be classified?

Class I: Clean
Class III: Contaminated
Class II: Clean-Contaminated
Class IV: Dirty/Infected (Correct answer)

Correct answer: Class IV: Dirty/Infected

A Class IV (Dirty/Infected) wound is one in which the organisms causing the postoperative infection were present in the operative field before the procedure. This includes old traumatic wounds with devitalized tissue and procedures involving existing clinical infection or perforated viscera. A perforated ulcer with established infection/peritonitis fits this definition. Class I is a clean, uninfected wound. Class II involves entering a hollow viscus under controlled conditions. Class III is a contaminated wound, such as one with gross spillage from the GI tract or a major break in sterile technique.

Question 74: During retraction of the bowel, which technique best prevents serosal injury?

Packing moist laparotomy sponges around bowel before applying retractors (Correct answer)
Using sharp Richardson retractors directly on bowel loops
Using electrocautery to retract tissue
Applying towel clips to bowel walls for traction

Correct answer: Packing moist laparotomy sponges around bowel before applying retractors

Moist laparotomy sponges cushion and protect the bowel serosa from injury by mechanical retractors.

Question 75: The prone position with arms extended forward on arm boards (resembling a flying posture) is most commonly called:

Superman (prayer) position (Correct answer)
Jackknife (Kraske) position
Modified Fowler position
Standard prone with lateral arm boards

Correct answer: Superman (prayer) position

The Superman or prayer position places the prone patient with arms extended forward on arm boards, used for certain cervical spine and posterior thoracic procedures.

Question 76: A fenestrated surgical drape contains:

An adhesive strip to secure the drape to the skin
A pre-cut opening that exposes the operative site (Correct answer)
A transparent window for instrument visualization
An absorbent inner layer to capture blood

Correct answer: A pre-cut opening that exposes the operative site

A fenestrated drape has a pre-cut opening (fenestration) positioned over the operative site, exposing only the area to be incised while keeping everything else covered.

Question 77: During a procedure, the circulating nurse accidentally touches the sterile back table with their non-sterile scrubs. The contact was brief but definite. What is the most appropriate action?

Place a sterile towel over the contaminated area.
Ignore the contact as it was minor.
Move sterile items away from the point of contact.
Consider the entire sterile field contaminated and replace it. (Correct answer)

Correct answer: Consider the entire sterile field contaminated and replace it.

The principles of aseptic technique are absolute; if a non-sterile item touches a sterile field, the field is considered contaminated. The extent of microbial transfer is unknown, and simply covering the area or moving items away does not guarantee sterility. To ensure patient safety and prevent SSI, the entire field must be broken down and a new sterile field established.

Question 78: Which meningeal layer closely adheres to the brain surface and follows all gyri and sulci?

Pia mater (Correct answer)
Dura mater
Arachnoid mater
Periosteal layer

Correct answer: Pia mater

The pia mater is the innermost and most delicate meningeal layer, closely adherent to the brain surface and dipping into every sulcus and fissure.

Question 79: The surgical first assistant is managing a Bookwalter retractor system. To prevent neuropraxia, which precaution is essential?

Use only metal blades regardless of tissue type
Set the ring as low as possible in the wound
Ensure blades are not pressing on peripheral nerves, especially the femoral nerve in pelvic cases (Correct answer)
Tighten all blades to maximum tension immediately

Correct answer: Ensure blades are not pressing on peripheral nerves, especially the femoral nerve in pelvic cases

Rigid retractor blades can compress the femoral nerve at the psoas margin in pelvic surgery, causing postoperative neuropraxia if not carefully positioned.

Question 80: The angle of Louis (sternal angle) is a reliable surface landmark for identifying which anatomic structure?

Aortic valve projection
First rib articulation
Xiphoid process
Carina and bifurcation of the trachea (Correct answer)

Correct answer: Carina and bifurcation of the trachea

The sternal angle corresponds to the T4–T5 vertebral level, marking the carina where the trachea bifurcates into the main bronchi.

Question 81: Which preoperative positioning consideration is most critical for a patient with severe osteoporosis scheduled for a prolonged orthopedic procedure?

Avoiding all pillow supports to keep the spine neutral
Placing the patient in steep Trendelenburg to improve venous return
Using padding and careful positioning to prevent fractures and pressure injuries (Correct answer)
Positioning the patient immediately after induction without assessment

Correct answer: Using padding and careful positioning to prevent fractures and pressure injuries

Osteoporotic bones are highly susceptible to fracture under pressure; meticulous padding and gentle positioning are essential to prevent injury.

Question 82: A patient undergoing total hip arthroplasty in the lateral decubitus position develops intraoperative hypotension after cementation. The MOST likely cause is:

Latex allergy reaction
Fat embolism from reaming
Positional air embolism
Bone cement implantation syndrome (BCIS) (Correct answer)

Correct answer: Bone cement implantation syndrome (BCIS)

Bone cement implantation syndrome occurs when bone cement monomer, fat, and marrow particles embolize during pressurization, causing hypotension, hypoxia, and cardiac arrhythmias.

Question 83: A patient with a history of malignant hyperthermia susceptibility (MHS) requires which preoperative measure?

Routine administration of volatile anesthetics
Preoperative cooling blanket application
Avoidance of triggering agents and preparation of dantrolene (Correct answer)
Administration of succinylcholine prophylactically

Correct answer: Avoidance of triggering agents and preparation of dantrolene

MHS patients require avoidance of volatile anesthetics and succinylcholine, with dantrolene immediately available for treatment.

Question 84: During a laparoscopic procedure, the surgeon requests increasing the insufflation pressure. As the surgical first assistant, what is the primary concern with excessively high intra-abdominal pressure?

Increased risk of bowel injury
Impaired venous return and decreased cardiac output (Correct answer)
Reduced visibility of the operative field
Increased bleeding from port sites

Correct answer: Impaired venous return and decreased cardiac output

High intra-abdominal pressure compresses the vena cava, reducing venous return and decreasing cardiac output, which can cause hemodynamic instability.

Question 85: Gelatin sponge (Gelfoam) achieves hemostasis primarily by which mechanism?

Providing a scaffold for platelet aggregation and clot formation (Correct answer)
Directly lysing red blood cells
Releasing vasoconstrictors into tissue
Activating the extrinsic coagulation pathway chemically

Correct answer: Providing a scaffold for platelet aggregation and clot formation

Gelfoam acts as a physical matrix that absorbs blood and provides a surface on which platelets aggregate and fibrin polymerizes.

Question 86: The surgical first assistant is controlling hemorrhage from a mesenteric vessel. Which maneuver provides immediate proximal control?

Applying electrocautery immediately to the bleeding vessel
Applying distal pressure only
Packing the entire abdomen and waiting
Digital pressure proximal to the bleeding point while suture ligature is prepared (Correct answer)

Correct answer: Digital pressure proximal to the bleeding point while suture ligature is prepared

Digital compression proximal to the bleeding vessel controls hemorrhage and allows time to prepare definitive hemostatic measures.

Question 87: During a procedure, the CSFA observes a circulating nurse, who is not gowned and gloved, reach over the sterile back table to retrieve an item from the far side. What is the most appropriate immediate action for the CSFA to take?

Immediately state that the field has been contaminated and request that all potentially affected items be removed and replaced. (Correct answer)
Ask the surgeon if they believe the field is still sterile.
Wait until the end of the procedure to report the incident to the charge nurse.
Say nothing to avoid conflict and continue with the procedure.

Correct answer: Immediately state that the field has been contaminated and request that all potentially affected items be removed and replaced.

A core principle of aseptic technique is that non-sterile individuals or items must never cross over the sterile field. When this occurs, the field is considered contaminated. The CSFA has a duty to advocate for patient safety by immediately identifying the breach so the team can take corrective action, which includes removing and replacing any compromised supplies or drapes.

Question 88: A preoperative patient discloses using herbal supplement St. John's Wort daily. The primary concern for the surgical team is:

Decreased wound healing postoperatively
Increased risk of latex allergy reaction
Increased risk of malignant hyperthermia
Potential drug interactions affecting anesthesia metabolism and platelet function (Correct answer)

Correct answer: Potential drug interactions affecting anesthesia metabolism and platelet function

St. John's Wort induces cytochrome P450 enzymes, affecting anesthesia drug metabolism, and may also inhibit platelet aggregation.

Question 89: Which intervention is MOST effective in preventing postoperative deep vein thrombosis (DVT) in patients undergoing total hip arthroplasty?

Combination of pharmacologic anticoagulation and mechanical compression devices (Correct answer)
Sequential compression devices alone
Aspirin 81 mg daily alone
Early ambulation alone

Correct answer: Combination of pharmacologic anticoagulation and mechanical compression devices

Combined pharmacologic and mechanical prophylaxis provides superior DVT prevention compared to either modality used alone in high-risk orthopedic procedures.

Question 90: Which of the following applies to a sharps container's requirements? 1. self-closing lid to prevent overfilling 2. biohazard labels and color coding 3. durable, closable, leakproof, and puncture resistant 4. lids which allow sharps to enter by gravity

1 and 3 only
2, 3, and 4 only (Correct answer)
1, 2, and 3 only
1, 2, and 4 only

Correct answer: 2, 3, and 4 only

Sharps containers are essential for the safe disposal of contaminated sharp objects, preventing injuries and infection spread. They must feature clear biohazard labels and color coding (2) for easy identification. Crucially, they need to be durable, closable, leakproof, and puncture-resistant (3) to safely contain hazardous materials, and their lids should allow sharps to enter by gravity (4) to minimize direct contact.

Question 91: When assisting with a laparotomy in a patient with a history of multiple prior abdominal surgeries, the surgical first assistant should anticipate:

Larger operating space due to prior stretching
Dense adhesions requiring careful lysis before proceeding (Correct answer)
Absence of adhesions
Faster entry due to tissue thinning

Correct answer: Dense adhesions requiring careful lysis before proceeding

Prior abdominal surgeries reliably result in adhesion formation, which must be carefully lysed to prevent enterotomy.

Question 92: During a cesarean section, the surgical first assistant is asked to apply fundal pressure to assist delivery of the fetal head. At what point in the procedure is this maneuver performed?

After closure of the uterine incision
During the skin incision phase
After delivery of the placenta
After the uterine incision is made and the fetal head is being delivered (Correct answer)

Correct answer: After the uterine incision is made and the fetal head is being delivered

Fundal pressure is applied after the uterine incision (hysterotomy) to assist the surgeon in delivering the fetal head through the uterine opening.

Question 93: During a laparoscopic case, the surgeon reports poor visualization due to fogging of the scope lens. What is the first corrective action?

Increase the insufflation pressure
Turn off the OR lights
Replace the CO2 canister
Warm or apply anti-fog solution to the lens before reinsertion (Correct answer)

Correct answer: Warm or apply anti-fog solution to the lens before reinsertion

Warming the scope (in warm saline or with anti-fog solution) before insertion equalizes the temperature differential that causes condensation on the lens.

Question 94: Which antiseptic preparation requires a minimum drying and contact time before incision to achieve maximum antiseptic effect and to prevent surgical fire risk?

Povidone-iodine scrub solution
Chlorhexidine gluconate with alcohol (e.g., ChloraPrep) (Correct answer)
Triclosan-based surgical soap
Aqueous benzalkonium chloride

Correct answer: Chlorhexidine gluconate with alcohol (e.g., ChloraPrep)

Alcohol-based chlorhexidine preparations must dry completely before draping; the alcohol evaporation eliminates fire risk and the drying time ensures antimicrobial efficacy.

Question 95: Which patient position increases the risk of venous air embolism during preoperative IV line placement in the neck region?

Trendelenburg
Supine with legs elevated
Sitting upright (Correct answer)
Reverse Trendelenburg

Correct answer: Sitting upright

The sitting upright position creates negative venous pressure in the neck, increasing the risk of air entering during central line placement.

Question 96: The fascial compartment containing the carotid artery, internal jugular vein, and vagus nerve is called the:

Prevertebral fascia
Carotid sheath (Correct answer)
Pretracheal fascia
Visceral fascia

Correct answer: Carotid sheath

The carotid sheath is a condensation of cervical fascia enclosing the carotid artery, internal jugular vein, and vagus nerve.

Question 97: Which type of surgical drain relies on gravity and capillary action for passive drainage, without suction?

Jackson-Pratt (JP) drain
Hemovac drain
Penrose drain (Correct answer)
Blake drain

Correct answer: Penrose drain

The Penrose drain is a flat latex tube that drains passively by gravity and capillary action, without a reservoir or vacuum, and exits through a dependent portion of the wound.

Question 98: The ansa cervicalis nerve supplies which group of muscles relevant to anterior neck dissection?

Suprahyoid muscles
Scalene muscles
Sternocleidomastoid and trapezius
Infrahyoid strap muscles (Correct answer)

Correct answer: Infrahyoid strap muscles

The ansa cervicalis (C1–C3) innervates the infrahyoid strap muscles including the sternohyoid, sternothyroid, and omohyoid.

Question 99: A patient recovering from a hip arthroplasty suddenly develops pleuritic chest pain, dyspnea, and tachycardia on postoperative day 3. The most likely diagnosis is:

Myocardial infarction
Aspiration pneumonia
Pneumothorax
Pulmonary embolism (Correct answer)

Correct answer: Rochester-Pean clamp

The Rochester-Pean clamp is a large hemostat with full-length transverse serrations, designed for clamping larger tissue bundles and vessels.

Question 103: During a low anterior resection, meticulous dissection of the total mesorectal excision (TME) plane stays within which embryologic tissue plane?

Waldeyer's fascia posteriorly and Denonvilliers' fascia anteriorly (Correct answer)
Peritoneal reflection
Endopelvic fascia laterally only
Scarpa's fascia

Correct answer: Waldeyer's fascia posteriorly and Denonvilliers' fascia anteriorly

TME requires sharp dissection within the avascular holy plane bounded posteriorly by Waldeyer's fascia and anteriorly by Denonvilliers' fascia.

Question 104: The coronary ligament of the liver marks the boundary between which two hepatic surfaces?

Left lobe and caudate lobe
Diaphragmatic surface and the bare area (Correct answer)
Right lobe and the porta hepatis
Visceral surface and the falciform ligament

Correct answer: Diaphragmatic surface and the bare area

The coronary ligament reflects from the diaphragm to the liver, marking the boundary of the bare area (area nuda) on the diaphragmatic surface.

Question 105: During a Whipple procedure (pancreaticoduodenectomy), which structure must be carefully preserved to maintain venous drainage of the remnant pancreas?

Portal vein
Inferior mesenteric vein
Superior mesenteric vein (Correct answer)
Splenic vein

Correct answer: Superior mesenteric vein

The superior mesenteric vein runs posterior to the neck of the pancreas and must be preserved to allow venous drainage of the pancreatic remnant.

Question 106: Which of the following is an example of a prion-related disease relevant to surgical infection control?

Herpes simplex encephalitis
Methicillin-resistant Staphylococcus aureus (MRSA) infection
Creutzfeldt-Jakob disease (CJD) (Correct answer)
Clostridium difficile colitis

Correct answer: Creutzfeldt-Jakob disease (CJD)

Creutzfeldt-Jakob disease is caused by prions — misfolded proteins that are resistant to standard sterilization — requiring special instrument handling protocols.

Question 107: Which opioid is associated with 'wooden chest syndrome' (chest wall rigidity) when given in large or rapid IV doses?

Fentanyl (Correct answer)
Morphine
Meperidine
Hydromorphone

Correct answer: Fentanyl

Fentanyl and other potent synthetic opioids can cause rapid-onset chest wall rigidity, impairing ventilation and requiring NMB agent treatment.

Question 108: Which ligament of the knee prevents anterior displacement of the tibia on the femur and is most commonly reconstructed using patellar tendon autograft?

Arcuate ligament
Anterior cruciate ligament (Correct answer)
Medial collateral ligament
Posterior cruciate ligament

Correct answer: Anterior cruciate ligament

The ACL is the primary restraint to anterior tibial translation and is the most frequently reconstructed knee ligament, often using the central third of the patellar tendon.

Question 109: Regarding sterility of the draped instrument back table, which statement is correct?

Only the top horizontal surface is sterile; the sides and underside are not sterile (Correct answer)
The entire drape including the underside is considered sterile
Sterility extends 12 inches below the top surface on all sides
The back table cover is semi-sterile and can be touched with non-sterile gloves

Correct answer: Only the top horizontal surface is sterile; the sides and underside are not sterile

Only the top surface of the draped back table is considered part of the sterile field; the sides and underside are not sterile and must not be touched with sterile gloves.

Question 110: What is the recommended action when a circulating nurse must hand a sterile item to a scrubbed person?

Pass it directly hand-to-hand quickly to minimize exposure
Place it on the back table after glancing at the field
Unwrap it and set it on any available surface near the field
Drop or flip it onto the sterile field without touching the inner contents (Correct answer)

Correct answer: Drop or flip it onto the sterile field without touching the inner contents

The circulator must present the sterile item so the scrubbed person can retrieve it without the non-sterile packaging touching the sterile field.

Question 111: A patient develops bronchospasm during anesthesia induction. Which drug class is the FIRST-LINE bronchodilator used intraoperatively?

Corticosteroids
Antihistamines
Beta-2 agonists (Correct answer)
Anticholinergics

Correct answer: Beta-2 agonists

Beta-2 agonists such as albuterol are first-line agents for acute bronchospasm because they rapidly relax bronchial smooth muscle.

Question 112: Which of the following interventions is the primary treatment for postoperative urinary retention (POUR) after spinal anesthesia?

Oral tamsulosin and observation
Suprapubic percussion and increased oral fluid intake
Urinary catheterization (Correct answer)
IV furosemide administration

Correct answer: Urinary catheterization

Urinary catheterization is the primary treatment for POUR when the bladder is significantly distended and the patient cannot void spontaneously.

Question 113: A surgical instrument contaminated with blood falls to the floor during a procedure. The CORRECT action is to:

Hand it off the sterile field and obtain a replacement sterile instrument (Correct answer)
Wipe it with a sterile towel and continue using it
Rinse it with sterile saline and return it to the field
Flash sterilize it if the case is urgent

Correct answer: Hand it off the sterile field and obtain a replacement sterile instrument

Any item that falls below the level of the sterile field or contacts a non-sterile surface is considered contaminated and must be removed and replaced.

Question 114: Which preoperative skin preparation agent is contraindicated for use near the ears and eyes?

Povidone-iodine
Chlorhexidine gluconate (Correct answer)
Isopropyl alcohol
Benzalkonium chloride

Correct answer: Chlorhexidine gluconate

Chlorhexidine is ototoxic and can cause corneal injury; it must not be used near the ears or eyes.

Question 115: When performing a sigmoid colectomy for cancer, the surgeon ligates the inferior mesenteric artery (IMA) at its origin from the aorta. To ensure viability of the remaining descending colon and rectal stump for anastomosis, the surgical team relies on collateral circulation primarily from which arterial structure?

Arc of Riolan
Ileocolic artery
Marginal artery of Drummond (Correct answer)
Superior rectal artery

Correct answer: Marginal artery of Drummond

The marginal artery of Drummond is a continuous arterial arcade that runs along the mesenteric border of the entire colon. It connects the terminal branches of the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA), providing a critical collateral pathway. When the IMA is ligated, blood flow from the middle colic artery (a branch of the SMA) can perfuse the left colon via this marginal artery.

Question 116: A patient reports a latex allergy during preoperative assessment. The FIRST action by the surgical first assistant should be:

Proceed with surgery using standard gloves
Administer prophylactic diphenhydramine
Document and alert the entire surgical team to prepare a latex-free environment (Correct answer)
Cancel the surgical case immediately

Correct answer: Document and alert the entire surgical team to prepare a latex-free environment

Documenting and alerting the team allows preparation of a latex-free environment, the standard protocol for latex-allergic patients.

Question 117: During a hepatic resection, the Pringle maneuver is used to control inflow. This maneuver involves clamping the:

Portal triad (hepatoduodenal ligament containing portal vein, hepatic artery, and bile duct) (Correct answer)
Splenic artery
Hepatic veins only
Inferior vena cava

Correct answer: Portal triad (hepatoduodenal ligament containing portal vein, hepatic artery, and bile duct)

The Pringle maneuver clamps the hepatoduodenal ligament to occlude portal vein and hepatic artery inflow, reducing hepatic hemorrhage.

Question 118: The brachial plexus terminal branches arise from which anatomical levels?

C6-T1
C4-C8
C4-T1
C5-T1 (Correct answer)

Correct answer: C5-T1

The brachial plexus is formed from the ventral rami of C5 through T1, giving rise to all major nerves of the upper extremity.

Question 119: When positioning a patient, which of the following should be taken into account? 1. Patency of the airway is the prime concern when positioning a patient 2. Pressue injuries are most common after surgical procedures lasting one hour or longer. 3. An anesthetized patient with muscle paralysis is at increased risk for muscle strain 4. The most common sites of peripheral nerve injury are the divisions of the brachial plexus and the ulnar, radial, peroneal, and facial nerves

respiratory compromise
1, 2, and 4 only (Correct answer)
incompetent valves
1 and 3 only

Correct answer: 1, 2, and 4 only

When positioning a patient for surgery, ensuring a patent airway (1) is the top priority to maintain oxygenation. Pressure injuries (2) are a significant risk, especially during procedures lasting an hour or longer, necessitating careful padding. Anesthetized patients with muscle paralysis are highly vulnerable to peripheral nerve injuries (4) due to the absence of protective reflexes, making precise positioning critical. Statement 3 is incorrect as muscle paralysis *increases* the risk of muscle strain, not decreases it.

Question 120: Which preoperative assessment finding requires immediate notification to the anesthesia team and surgeon before proceeding?

Heart rate of 78 bpm
Blood pressure of 128/82 mmHg
Blood glucose of 380 mg/dL in a diabetic patient (Correct answer)
Temperature of 37.1°C (98.8°F)

Correct answer: Blood glucose of 380 mg/dL in a diabetic patient

Severely elevated blood glucose (380 mg/dL) indicates poor diabetic control and increases infection and healing risks, warranting provider notification.

Question 121: When using intraoperative ultrasound, the surgical first assistant should cover the sterile ultrasound probe with:

An unsterile drape from the back table
Nothing — probes are inherently sterile
A standard OR towel secured with a rubber band
A sterile ultrasound probe cover/sheath specifically designed for intraoperative use (Correct answer)

Correct answer: A sterile ultrasound probe cover/sheath specifically designed for intraoperative use

A sterile probe sheath maintains sterility of the operative field and protects the probe when it contacts intraoperative tissues or fluids.

Question 122: In Spaulding's classification, an endoscope used for bronchoscopy (touching non-intact mucosa) requires at minimum:

Low-level disinfection
Terminal sterilization
Intermediate-level disinfection
High-level disinfection (Correct answer)

Correct answer: High-level disinfection

Semi-critical items (contact with mucous membranes or non-intact skin) require high-level disinfection to eliminate all microorganisms except high numbers of bacterial spores.

Question 123: Which of the following correctly describes a 'break in sterile technique' that requires immediate action?

A scrubbed team member turns sideways to pass an instrument
A scrubbed team member reaches across the sterile field with an ungloved hand (Correct answer)
An unscrubbed circulator opens a sterile supply by tearing the package
The back table is set 12 inches from the OR bed

Correct answer: A scrubbed team member reaches across the sterile field with an ungloved hand

An ungloved (unscrubbed) hand crossing over or into the sterile field immediately contaminates it and requires the field to be re-established.

Question 124: During inguinal hernia repair, the ilioinguinal nerve runs within which anatomical space?

Inguinal canal (Correct answer)
Obturator canal
Femoral canal
Lacunar ligament space

Correct answer: Inguinal canal

The ilioinguinal nerve travels through the inguinal canal and exits via the superficial inguinal ring to supply the medial thigh and scrotum/labia.

Question 125: The anesthesia provider asks the CSFA to irrigate the wound with epinephrine-containing solution. The PRIMARY reason for epinephrine in local anesthetic solutions is to:

Accelerate wound healing
Produce vasoconstriction and prolong analgesia (Correct answer)
Prevent allergic reactions
Increase rate of drug absorption

Correct answer: Produce vasoconstriction and prolong analgesia

Epinephrine causes local vasoconstriction, which slows absorption of the local anesthetic, prolongs its effect, and reduces systemic toxicity.

Question 126: A postoperative patient on a beta-blocker develops a heart rate of 48 bpm, blood pressure of 88/54 mmHg, and is symptomatic with dizziness. The MOST appropriate pharmacologic intervention is:

Amiodarone for rate control
Digoxin to improve contractility
Atropine IV for symptomatic bradycardia (Correct answer)
Metoprolol IV to support cardiac conduction

Correct answer: Atropine IV for symptomatic bradycardia

Atropine is the first-line treatment for symptomatic bradycardia by blocking vagal tone to increase heart rate.

Question 127: The scrub person and circulator are performing the final count for a major abdominal procedure. A single ray-tec sponge is missing. After a thorough search of the sterile field, linen, and trash, it is not found. What is the most appropriate next step?

The surgeon performs a manual exploration of the wound while an intraoperative x-ray is ordered. (Correct answer)
Break scrub and search the operating room floor and surrounding areas again.
Assume the sponge was kicked into a trash receptacle and close the patient.
Document the count as incorrect and proceed with skin closure.

Correct answer: The surgeon performs a manual exploration of the wound while an intraoperative x-ray is ordered.

When a surgical item is missing and cannot be located after a thorough search, the surgeon must be notified to perform a manual exploration of the wound. Concurrently, an intraoperative x-ray must be ordered to rule out a retained foreign body before the final closure of the wound cavity.

Question 128: Which retroperitoneal structure crosses the pelvic brim at the bifurcation of the iliac vessels and is at risk during pelvic surgery?

Ureter (Correct answer)
Ilioinguinal nerve
Femoral nerve
Obturator nerve

Correct answer: Ureter

The ureter crosses the pelvic brim at the bifurcation of the common iliac artery, making it vulnerable during pelvic dissections such as hysterectomy and colorectal resections.

Question 129: Which physiologic principle explains why a tourniquet applied to a limb causes metabolic acidosis upon release?

Tourniquet increases systemic vascular resistance raising pH
Reperfusion delivers oxygen causing alkalosis
Ischemic tissue accumulates lactic acid which washes into circulation on deflation (Correct answer)
Hyperventilation during ischemia releases CO2

Correct answer: Ischemic tissue accumulates lactic acid which washes into circulation on deflation

Anaerobic metabolism in the ischemic limb produces lactic acid, which rapidly enters systemic circulation when the tourniquet is deflated, causing transient metabolic acidosis.

Question 130: Which sterilization method is most appropriate for heat-sensitive endoscopic equipment?

Steam autoclave at 132°C
Dry heat oven at 170°C
Ethylene oxide (EO) gas sterilization (Correct answer)
Gravity displacement autoclave

Correct answer: Ethylene oxide (EO) gas sterilization

Ethylene oxide gas sterilization operates at low temperatures, making it ideal for heat-sensitive instruments like endoscopes.

Question 131: A patient in the PACU, shortly after extubation, develops inspiratory stridor, use of accessory muscles, and paradoxical chest movements ('see-saw' breathing) with no audible air movement. This is most indicative of what emergency?

Aspiration Pneumonitis
Pulmonary Edema
Bronchospasm
Complete Laryngospasm (Correct answer)

Correct answer: Complete Laryngospasm

The signs described—inspiratory stridor progressing to silence, paradoxical chest movements, and retractions despite respiratory effort—are classic manifestations of a complete laryngospasm. This is a complete, involuntary closure of the vocal cords, creating a total upper airway obstruction. Bronchospasm typically involves wheezing on exhalation. Pulmonary edema and aspiration would present with different lung sounds (crackles/rales) and would not typically cause a silent, obstructive upper airway pattern.

Question 132: A scrub technologist notices a hole in the outer wrap of a sterile pack just before opening it. The correct action is to:

Return the pack to sterile processing for repackaging and re-sterilization (Correct answer)
Cover the hole with sterile tape and proceed
Open the pack carefully and inspect the inner contents under a light
Use the pack if the inner wrap appears intact

Correct answer: Return the pack to sterile processing for repackaging and re-sterilization

Any breach in the outer packaging invalidates sterility and requires the item to be returned for repackaging and re-sterilization.

Question 133: Which preoperative intervention is most important to prevent surgical site infections (SSI)?

Appropriate timing of prophylactic antibiotics within 60 minutes before incision (Correct answer)
Routine preoperative blood transfusion
Postoperative wound irrigation with betadine
Shaving the surgical site the night before surgery

Correct answer: Appropriate timing of prophylactic antibiotics within 60 minutes before incision

Prophylactic antibiotics administered within 60 minutes before incision significantly reduce SSI risk, per evidence-based guidelines.

Question 134: Which suture material is most appropriate for closing a contaminated abdominal fascia?

Nylon monofilament
Polyglactin 910 (braided absorbable)
Poliglecaprone 25 (monofilament absorbable) (Correct answer)
Silk (non-absorbable multifilament)

Correct answer: Poliglecaprone 25 (monofilament absorbable)

Monofilament absorbable sutures like poliglecaprone resist harboring bacteria compared to braided sutures in contaminated fields.

Question 135: The triangle of Calot, critical for safe cholecystectomy, is bounded superiorly by which structure?

Cystic duct
Liver (visceral surface) (Correct answer)
Common hepatic duct
Cystic artery

Correct answer: Liver (visceral surface)

The triangle of Calot is bounded superiorly by the visceral surface of the liver, medially by the common hepatic duct, and inferiorly by the cystic duct.

Question 136: Which type of wound healing occurs when a wound is left open to granulate, fill, and re-epithelialize without surgical closure?

Primary intention (first intention)
Quaternary healing
Tertiary intention (delayed primary closure)
Secondary intention (Correct answer)

Correct answer: Secondary intention

Secondary intention healing occurs when wounds are left open and heal by granulation tissue formation, wound contraction, and epithelialization, typically used for infected or heavily contaminated wounds.

Question 137: When performing a surgical hand scrub using the anatomical (timed) method, what is the minimum required scrub duration per the Association of periOperative Registered Nurses (AORN) guidelines?

1 minute
5 minutes (Correct answer)
10 minutes
3 minutes

Correct answer: 5 minutes

AORN guidelines recommend a minimum 5-minute surgical scrub using the timed anatomical method for initial cases.

Question 138: When performing a postoperative surgical wound assessment, which finding requires IMMEDIATE notification of the surgeon?

Small amount of serosanguineous drainage on the dressing
Mild periincisional erythema limited to 1 cm
Wound edges separating with visible bowel loops (evisceration) (Correct answer)
Slight edema at wound edges on postoperative day 2

Correct answer: Wound edges separating with visible bowel loops (evisceration)

Evisceration (protrusion of abdominal organs through the wound) is a surgical emergency requiring immediate coverage with a sterile moist dressing and surgeon notification.

Question 139: During a posterolateral thoracotomy, the surgical first assistant retracts which muscle that originates from the lower six ribs and inserts on the iliac crest and thoracolumbar fascia?

Rhomboid major
Serratus anterior
External intercostal
Latissimus dorsi (Correct answer)

Correct answer: Latissimus dorsi

The latissimus dorsi is the large, flat muscle typically divided or retracted during posterolateral thoracotomy to access the thoracic cavity.

Question 140: Which physiologic mechanism primarily maintains mean arterial pressure when a patient transitions from supine to upright positioning on the operating table?

Atrial natriuretic peptide release
Increased stroke volume
Baroreceptor-mediated sympathetic vasoconstriction (Correct answer)
Parasympathetic withdrawal from the SA node

Correct answer: Baroreceptor-mediated sympathetic vasoconstriction

Baroreceptors in the carotid sinus and aortic arch detect pressure drops and trigger sympathetic vasoconstriction to maintain MAP.

Question 141: Which retractor is BEST suited for providing self-retaining exposure during an open abdominal procedure?

Bookwalter retractor (Correct answer)
Army-Navy retractor
Deaver retractor
Richardson retractor

Correct answer: Bookwalter retractor

The Bookwalter is a self-retaining retractor system that attaches to the operating table and provides hands-free abdominal exposure without requiring an assistant to hold it.

Question 142: The NPO (nil per os) guideline for clear liquids before elective surgery in adults is typically:

4 hours
1 hour
8 hours
2 hours (Correct answer)

Correct answer: 2 hours

ASA guidelines recommend NPO for clear liquids at least 2 hours before elective procedures to reduce aspiration risk.

Question 143: The lymphatic drainage of the lower rectum primarily flows to which lymph node group?

Inguinal nodes
Para-aortic nodes
Superior mesenteric nodes
Internal iliac nodes (Correct answer)

Correct answer: Internal iliac nodes

The lower rectum drains primarily to the internal iliac (hypogastric) lymph nodes, which is clinically significant in rectal cancer staging.

Question 144: During a laparoscopic cholecystectomy, the surgical first assistant notes the cystic duct has not been clearly identified. What is the most appropriate next action?

Alert the surgeon and advocate for further dissection of Calot's triangle (Correct answer)
Convert to open procedure without consulting the surgeon
Clip and divide the structure immediately
Irrigate the field and proceed with clipping

Correct answer: Alert the surgeon and advocate for further dissection of Calot's triangle

Failure to clearly identify the cystic duct before clipping risks bile duct injury; the SFA must advocate for safe dissection before proceeding.

Question 145: When assisting with a total knee arthroplasty, which retractor is most commonly used to expose the medial compartment?

Hohmann retractor (Correct answer)
Army-Navy retractor
Richardson retractor
Deaver retractor

Correct answer: Hohmann retractor

Hohmann retractors are curved and designed to lever around bone, making them ideal for orthopedic joint exposure.

Question 146: A critical, non-porous, non-lumened surgical instrument is accidentally dropped on the floor mid-procedure. The surgeon states it is urgently needed to complete the case. According to AORN and AAMI guidelines, what is the most appropriate course of action?

Process the instrument using an Immediate-Use Steam Sterilization (IUSS) cycle, ensuring it is first cleaned, placed in a validated rigid container, and transported aseptically. (Correct answer)
Wipe the instrument with an alcohol-based wipe and return it to the sterile field.
Submerge the instrument in glutaraldehyde for 10 minutes before returning it to the field.
Process the instrument using the shortest available IUSS cycle without a container to save time.

Correct answer: Process the instrument using an Immediate-Use Steam Sterilization (IUSS) cycle, ensuring it is first cleaned, placed in a validated rigid container, and transported aseptically.

Immediate-Use Steam Sterilization (IUSS), formerly known as 'flash sterilization,' should be kept to a minimum and used only in urgent situations. The complete, proper procedure must be followed, which includes thorough cleaning and decontamination, placement in a closed, rigid sterilization container validated for IUSS, running the manufacturer-specified cycle, and aseptic transfer to the sterile field.

Question 147: A patient with a known aspirin allergy states she took aspirin two days ago. The most relevant concern is:

Allergic reaction during surgery
Increased risk of postoperative nausea
Reduced effectiveness of prophylactic antibiotics
Impaired platelet function increasing intraoperative bleeding risk (Correct answer)

Correct answer: Impaired platelet function increasing intraoperative bleeding risk

Aspirin irreversibly inhibits platelet function for the platelet lifespan (~7-10 days), increasing the risk of intraoperative bleeding.

Question 148: Which preoperative measure is most important when preparing a patient with a known difficult airway?

Ensuring availability of difficult airway equipment and a backup airway plan (Correct answer)
Applying a cervical collar for stability
Administering a sedative premedication to relax the patient
Scheduling the case at the start of the day only

Correct answer: Ensuring availability of difficult airway equipment and a backup airway plan

For difficult airway patients, the team must ensure specialized equipment (video laryngoscope, LMA, surgical airway tools) and a clear backup plan are ready.

Question 149: When should the surgical hand antisepsis (surgical scrub) be performed?

Immediately before donning sterile gloves only if gloves are torn
After gowning but before gloving
Before every surgical procedure, prior to gowning and gloving (Correct answer)
Only when the surgeon's hands are visibly soiled

Correct answer: Before every surgical procedure, prior to gowning and gloving

Surgical hand antisepsis must be performed before every procedure and before gowning and gloving to reduce transient and resident flora.

Question 150: During the preoperative phase, the surgical first assistant notes the patient has not removed her tongue ring. The most appropriate action is:

Tape it in place so it does not dislodge
Leave it in place as it will not interfere with surgery
Request the patient remove all oral jewelry to prevent airway complications (Correct answer)
Contact the surgeon and leave the decision to them

Correct answer: Request the patient remove all oral jewelry to prevent airway complications

Oral jewelry can become dislodged during intubation, risking airway obstruction or aspiration, so removal is required.
