Correct answer: It is the threshold associated with invasive burn wound infection

A bacterial count >10^5 organisms per gram of tissue indicates invasive infection that can impede graft take and cause systemic sepsis.

Question 42: In a burn patient with a 40% TBSA burn, how does severe protein catabolism typically manifest on laboratory evaluation?

Decreased BUN
Elevated serum albumin
Increased muscle mass
Negative nitrogen balance (Correct answer)

Correct answer: Negative nitrogen balance

Massive protein catabolism causes negative nitrogen balance where nitrogen losses through urine and wounds exceed nitrogen intake, leading to muscle wasting.

Question 43: What is a common complication of inadequate fluid resuscitation?

Scar hypertrophy
Hyperkalemia
Elevated blood sugar
Hypovolemic shock and organ failure (Correct answer)

Correct answer: Hypovolemic shock and organ failure

Inadequate fluid resuscitation in burn patients leads to significant fluid shifts and loss from the intravascular space. This can quickly result in hypovolemic shock, where the body doesn't have enough blood and fluid to pump, leading to decreased perfusion and eventual organ failure due to lack of oxygen and nutrients. Prompt and adequate fluid replacement is crucial to prevent these life-threatening complications.

Question 44: Which route of nutrition is preferred for burn patients when the gastrointestinal tract is functional?

Peripheral IV glucose infusion
Oral supplementation alone
Total parenteral nutrition
Enteral nutrition via nasogastric tube (Correct answer)

Mafenide acetate penetrates eschar more effectively than silver sulfadiazine, making it the preferred agent when deep infection is suspected or confirmed.

Question 47: What is the importance of follow-up education post-discharge?

It is unnecessary for adults.
It replaces home care.
It is only for documentation.
It reinforces prior teaching and helps with long-term care adherence (Correct answer)

Correct answer: It reinforces prior teaching and helps with long-term care adherence

Follow-up education post-discharge is essential because it reinforces the information provided during hospitalization and addresses new questions or challenges that arise at home. This ongoing support helps patients maintain adherence to their long-term care plan, manage their recovery effectively, and prevent complications, promoting sustained well-being. It bridges the gap between hospital and home care.

Question 48: What metabolic complication is most characteristic of the hypermetabolic stress response in severe burn patients?

Hypothermia
Hypoglycemia
Metabolic alkalosis
Hyperglycemia (Correct answer)

Correct answer: Hyperglycemia

Stress hormones (catecholamines, cortisol, glucagon) promote gluconeogenesis and insulin resistance, causing hyperglycemia in burn patients.

Question 49: A burn patient's morning labs show WBC 2,800 cells/µL (down from 18,000 yesterday). What does this leukopenia suggest?

Bone marrow suppression or overwhelming sepsis (Correct answer)
Steroid therapy effect
Successful treatment of infection
Normal inflammatory resolution

Correct answer: Bone marrow suppression or overwhelming sepsis

A sudden drop in WBC to leukopenic levels in a burn patient is an ominous sign indicating bone marrow suppression from overwhelming sepsis or severe systemic illness.

Question 50: A burn patient is receiving split-thickness skin grafts. Which post-operative assessment finding at the graft site would indicate graft failure?

Fluid collection (seroma or hematoma) beneath the graft (Correct answer)
Mild wound edge erythema at 48 hours
Minimal pain at donor site
Slight adherence of graft at 72 hours

Correct answer: Fluid collection (seroma or hematoma) beneath the graft

Seroma or hematoma beneath a graft prevents the graft from adhering to the wound bed, leading to graft failure due to impaired nutrient diffusion.

Question 51: In Certified Burn Registered Nurse, what is the PRIMARY purpose of conducting an initial assessment?

To fulfill administrative paperwork requirements
To establish a baseline and identify needs for appropriate action (Correct answer)
To demonstrate the assessor's expertise
To generate documentation for billing purposes

Correct answer: To establish a baseline and identify needs for appropriate action

The initial assessment establishes a baseline of current conditions and identifies specific needs. This foundational information guides all subsequent decisions, planning, and interventions.

Question 52: A burn survivor reports flashbacks and nightmares 6 weeks post-injury. The nurse should:

Reassure the patient this is normal and will resolve without intervention
Screen formally for PTSD and refer to psychology if criteria are met (Correct answer)
Advise the patient to avoid thinking about the injury
Prescribe benzodiazepines for sleep

Correct answer: Screen formally for PTSD and refer to psychology if criteria are met

Persistent re-experiencing symptoms at 6 weeks warrant formal PTSD screening and referral to mental health services for evidence-based treatment.

Question 53: What is the recommended daily wear duration for compression garments during the active scar remodeling phase?

23 hours per day (Correct answer)
8–12 hours per day

Correct answer: Protein

Burn patients require 1.5–3 g/kg/day of protein due to massive catabolism, wound healing demands, and nitrogen losses from wound exudate.

Question 58: Why is patient education important in burn recovery?

It ensures insurance approval.
It helps patients take an active role in their recovery process (Correct answer)
It eliminates the need for wound care.
It reduces the need for healthcare providers.

Correct answer: It helps patients take an active role in their recovery process

Patient education is vital in burn recovery because it empowers patients with the knowledge and skills needed to actively participate in their own care. Understanding their condition, treatment plan, wound care, and rehabilitation goals fosters self-management and adherence, leading to better long-term outcomes and a smoother recovery journey. This active involvement promotes independence and self-efficacy.

Question 59: Which electrolyte abnormality is most commonly seen during the first 48 hours of major burn resuscitation?

Hypernatremia
Hyperkalemia (Correct answer)
Hypomagnesemia
Hypercalcemia

Correct answer: Hyperkalemia

Massive cell destruction releases intracellular potassium, causing hyperkalemia in the immediate post-burn period.

Question 60: Which electrolyte abnormality is most commonly seen in the first 48–72 hours post-major burn due to tissue destruction?

Hypokalemia
Hypernatremia
Hyperkalemia (Correct answer)
Hypercalcemia

Correct answer: Hyperkalemia

Massive cell destruction releases intracellular potassium, causing hyperkalemia in the early post-burn period.

Question 61: Which complication can result from overfeeding burn patients with excessive carbohydrates?

Hypokalemia
Hypocalcemia
Hepatic steatosis and CO2 retention (Correct answer)
Metabolic alkalosis

Correct answer: Hepatic steatosis and CO2 retention

Excess carbohydrates are converted to fat in the liver (hepatic steatosis) and produce excess CO2, worsening respiratory status in burn patients.

Question 62: What is the significance of monitoring white blood cell (WBC) counts in burn patients?

WBC count has no relevance.
It indicates hydration status.
It helps assess infection or sepsis risk (Correct answer)
It measures renal function.

Correct answer: It helps assess infection or sepsis risk

White blood cell (WBC) counts are a crucial indicator in burn patients because an elevated count (leukocytosis) or a significantly depressed count (leukopenia) can signal the presence of infection or sepsis. Burn injuries cause a systemic inflammatory response, and changes in WBC count help clinicians identify and monitor the body's response to potential pathogens. This monitoring aids in early detection and management of infectious complications.

Question 63: Which of the following methods is best for monitoring fluid resuscitation success?

Heart rate only.
Blood sugar levels.
Urine output greater than 0.5 mL/kg/hr (Correct answer)
Capillary refill time.

Correct answer: Urine output greater than 0.5 mL/kg/hr

Monitoring urine output is the most reliable and direct method for assessing the adequacy of fluid resuscitation in burn patients. A urine output greater than 0.5 mL/kg/hr (for adults) indicates that the kidneys are adequately perfused and functioning well, signifying sufficient circulating blood volume. While other parameters like heart rate are important, urine output provides a direct measure of end-organ perfusion.

Question 64: What is the primary goal of therapeutic positioning in acute burn care?

Preventing contracture deformities and maintaining functional alignment (Correct answer)
Facilitating dressing changes
Patient comfort
Reducing fluid requirements

Correct answer: Preventing contracture deformities and maintaining functional alignment

Proper positioning maintains joints in anti-contracture positions to prevent deformity development during the acute healing phase.

Question 65: Which statement by a burn patient indicates SUCCESSFUL understanding of long-term scar maturation?

'My scar should be completely flat and pale within 3 months.'
'Scar remodeling can continue for up to 2 years, so I'll keep wearing my garment.' (Correct answer)
'Physical therapy is only needed if I feel pain in my scar.'
'Once the wound is healed, no further care is needed.'

Correct answer: 'Scar remodeling can continue for up to 2 years, so I'll keep wearing my garment.'

Burn scar maturation spans 12–24 months; understanding this timeline promotes adherence to long-term compression and rehabilitation therapy.

Question 66: A pediatric burn patient (age 8) is refusing dressing changes despite adequate analgesia. Which psychosocial strategy is MOST effective?

Restrain the child to complete the dressing change efficiently
Increase sedation for all future dressing changes
Postpone the dressing change until the child agrees
Use distraction techniques such as virtual reality or tablet games during the procedure (Correct answer)

Correct answer: Use distraction techniques such as virtual reality or tablet games during the procedure

Non-pharmacological distraction (e.g., VR, interactive games) is evidence-based for reducing procedural pain and anxiety in pediatric burn patients.

Question 67: What type of scar is characterized by raised, firm, erythematous tissue that remains within the original wound boundaries?

Atrophic scar
Contracture
Hypertrophic scar (Correct answer)
Keloid scar

Correct answer: Hypertrophic scar

Hypertrophic scars are raised, firm, and erythematous but stay confined within the original wound margins, unlike keloids which extend beyond them.

Question 68: Why is serum albumin considered a poor marker for acute nutritional status in burn patients?

It cannot be measured in burn patients
It is unaffected by nutrition
It only measures fat stores
Its long half-life and negative acute-phase response make it unreliable acutely (Correct answer)

Correct answer: Its long half-life and negative acute-phase response make it unreliable acutely

Albumin has a ~20-day half-life and falls as a negative acute-phase reactant during inflammation regardless of nutritional intake, making it unreliable acutely.

Question 69: What is the primary reason burn nurses use strict sterile technique rather than clean technique during wound debridement?

Clean technique is reserved for chronic wounds only
Sterile technique accelerates healing by reducing inflammation
Burn wounds lack skin barrier, making them highly susceptible to exogenous contamination (Correct answer)
Sterile technique is hospital policy only

Correct answer: Burn wounds lack skin barrier, making them highly susceptible to exogenous contamination

Absence of the skin barrier in burn wounds creates a direct portal for microorganism entry, necessitating sterile technique to prevent infection.

Question 70: A burn patient develops progressive dyspnea, hoarseness, and stridor 4 hours post-injury. What is the priority intervention?

Perform immediate endotracheal intubation (Correct answer)
Apply cool mist via face mask
Order a chest X-ray
Administer nebulized albuterol

Correct answer: Perform immediate endotracheal intubation

Hoarseness and stridor indicate impending airway obstruction from inhalation injury; immediate intubation before complete obstruction is the priority.

Question 71: A 70 kg patient has 40% TBSA burns. Using the Parkland formula, how many mL of Lactated Ringer's should be administered in the first 8 hours post-burn?

11,200 mL
5,600 mL (Correct answer)
2,800 mL
8,000 mL

Correct answer: 5,600 mL

Parkland: 4 mL × 70 kg × 40% = 11,200 mL total; half (5,600 mL) is given in the first 8 hours.

Question 72: What is the primary purpose of indirect calorimetry in burn patient care?

Calculate fluid balance
Monitor cardiac output
Determine actual resting energy expenditure (Correct answer)

Question 79: Which of the following is a key sign of sepsis in burn patients?

Localized redness
Elevated temperature with tachycardia and hypotension (Correct answer)
Normal blood pressure
Bradycardia

Correct answer: Elevated temperature with tachycardia and hypotension

Sepsis in burn patients is a severe systemic inflammatory response to infection, often characterized by a cluster of signs including elevated temperature (fever), tachycardia (increased heart rate), and hypotension (low blood pressure). These vital sign changes indicate a widespread physiological compromise and require immediate medical intervention. Localized redness alone is not indicative of systemic sepsis.

Question 80: Hypertonic saline resuscitation in burns is thought to offer which advantage over isotonic crystalloids?

It requires a greater total volume to achieve the same hemodynamic effect
It reduces total fluid volume needed by drawing interstitial fluid into the vasculature (Correct answer)
It is the standard of care recommended by all burn centers
It eliminates the risk of hypernatremia

Correct answer: It reduces total fluid volume needed by drawing interstitial fluid into the vasculature

Hypertonic saline's osmotic effect draws fluid from the interstitium into the intravascular space, potentially reducing the total resuscitation volume and edema.

Question 81: In a ventilated burn patient, which bundle element is most critical for preventing ventilator-associated pneumonia (VAP)?

Daily sedation vacation and elevation of head of bed to 30–45° (Correct answer)
Routine bronchoscopy every 48 hours
Keeping the cuff pressure below 15 cmH2O
Continuous nebulized antibiotics

Correct answer: Daily sedation vacation and elevation of head of bed to 30–45°

Daily sedation interruption combined with semi-recumbent positioning (30–45°) are core VAP bundle elements proven to reduce pneumonia incidence.

Question 82: A patient has circumferential full-thickness burns to both lower extremities with absent distal pulses and paresthesias. What intervention is indicated?

Emergent escharotomy (Correct answer)
Elevation of extremities and warm compresses
Doppler monitoring only
Immediate fasciotomy without escharotomy

Correct answer: Emergent escharotomy

Circumferential full-thickness burns create constrictive eschar that impairs circulation; escharotomy releases the constriction and restores distal perfusion.

Question 83: What is the benefit of involving family in patient education?

It delays discharge.
It makes care more expensive.
It improves understanding and emotional support for the patient (Correct answer)
It complicates the care plan.

Correct answer: It improves understanding and emotional support for the patient

Involving family in patient education is highly beneficial because it enhances their understanding of the patient's condition, care needs, and recovery process. Educated and involved family members can provide crucial emotional support, assist with home care, and advocate for the patient, ultimately contributing to a more positive and successful recovery. This creates a supportive environment for the patient.

Question 84: Ketamine is used as an analgesic-anesthetic adjunct in burn care primarily because it:

Reduces opioid-induced hyperalgesia when used alone

Ketamine's dissociative properties provide effective analgesia while maintaining airway protective reflexes, making it valuable for procedural pain in burn patients.

Question 85: What is the primary goal of early enteral nutrition in the critically burned patient from an infection prevention perspective?

Preventing hypoglycemia
Maintaining gut mucosal integrity to prevent bacterial translocation (Correct answer)
Increasing serum albumin levels rapidly
Reducing the need for TPN

Correct answer: Maintaining gut mucosal integrity to prevent bacterial translocation

Early enteral nutrition preserves intestinal mucosal integrity, preventing bacterial translocation across the gut wall, which can lead to systemic infection and sepsis.

Question 86: During the ebb phase of the burn stress response, which hemodynamic finding is most expected?

Elevated core temperature
Decreased vascular resistance
Decreased cardiac output (Correct answer)
Increased cardiac output

Correct answer: Decreased cardiac output

The ebb phase (first 48 hours) is characterized by decreased cardiac output, hypoperfusion, and reduced metabolic rate.

Question 87: Which sign most strongly suggests compartment syndrome in a circumferentially burned extremity?

Skin temperature equal to the contralateral limb
Pain with passive stretch of muscles in the affected compartment (Correct answer)
Mild pitting edema distal to the burn
Capillary refill of 3 seconds

Correct answer: Pain with passive stretch of muscles in the affected compartment

Pain out of proportion with passive muscle stretch is the most sensitive early indicator of compartment syndrome requiring urgent escharotomy or fasciotomy.

Question 88: Which trace element is commonly depleted in burn patients due to losses through wound exudate and is critical for wound healing?

Zinc (Correct answer)
Chloride
Phosphorus
Sodium

Correct answer: Zinc

Zinc is lost through burn wound exudate and its deficiency impairs wound healing, immune function, and protein synthesis.

Question 89: What is the primary goal of wound debridement in burn care?

Prevent debridement
Remove dead tissue and promote healing (Correct answer)
Promote scar formation
Reduce fluid loss

Correct answer: Remove dead tissue and promote healing

The primary goal of wound debridement in burn care is to remove dead, devitalized tissue (eschar) from the burn wound. Necrotic tissue provides a breeding ground for bacteria, increasing the risk of infection and impeding the natural healing process. By removing this tissue, debridement promotes a clean wound bed, reduces the bacterial load, and facilitates healthy granulation tissue formation and wound closure.

Question 90: What is the recommended hand hygiene technique upon leaving a burn patient's room?

Soap and water only, then alcohol rub
Either soap and water or alcohol-based rub is acceptable unless C. diff is suspected (Correct answer)
Alcohol-based hand rub only
No additional measures beyond standard glove use

Correct answer: Either soap and water or alcohol-based rub is acceptable unless C. diff is suspected

Alcohol-based hand rub is effective for most pathogens; soap and water is mandatory when Clostridioides difficile or visible soiling is present.

Question 91: When assessing a burn patient for signs of sepsis using the American Burn Association criteria, which parameter is NOT part of the definition?

Blood glucose >200 mg/dL in a non-diabetic patient
Arterial pH >7.45 (Correct answer)
Progressive tachycardia >110 bpm
Temperature >39°C or <36.5°C

Correct answer: Arterial pH >7.45

The ABA sepsis criteria include temperature extremes, tachycardia, tachypnea, thrombocytopenia, hyperglycemia, and inability to continue enteral feeds—alkalosis is not a criterion.

Question 92: Which pain assessment tool is particularly useful for pediatric burn patients or those unable to verbalize pain scores?

Vancouver Scar Scale
Abbreviated Burn Severity Index
FACES Pain Scale (Correct answer)

Question 97: Which formula is commonly used to estimate caloric needs in burn patients based on body weight and percent TBSA burned?

Fick equation
Mifflin-St Jeor equation
Harris-Benedict equation
Curreri formula (Correct answer)

Correct answer: Curreri formula

The Curreri formula estimates caloric needs by calculating 25 kcal/kg/day plus 40 kcal per percent TBSA burned.

Question 98: When educating a patient about scar management, which statement best describes the purpose of compression garments?

They eliminate the need for moisturizer application
They prevent infection by creating a sterile barrier
They reduce hypertrophic scar formation by applying continuous pressure (Correct answer)
They accelerate wound closure by increasing local perfusion

Correct answer: They reduce hypertrophic scar formation by applying continuous pressure

Compression garments apply continuous pressure (20–25 mmHg) that flattens and softens hypertrophic scars by reducing collagen overproduction.

Question 99: A burn patient develops abdominal compartment syndrome during resuscitation. Which intervention is most appropriate?

Switch from LR to normal saline
Reduce fluid rate and consider adding colloid or vasopressors (Correct answer)
Administer a bolus of albumin 25%
Increase IV fluid rate by 25%

Correct answer: Reduce fluid rate and consider adding colloid or vasopressors

Abdominal compartment syndrome signals over-resuscitation; decreasing crystalloid and adding colloid or vasopressors reduces total volume while maintaining perfusion.

Question 100: Which opioid analgesic is most appropriate for procedural pain (e.g., dressing changes) in burn patients due to its rapid onset and short duration of action?

Methadone
Codeine
Hydromorphone
Fentanyl (Correct answer)

Fentanyl is ideal for procedural pain in burn patients due to its rapid IV onset (1-2 minutes), short duration of action, and high potency, making it effective for painful dressing changes.

Question 101: High-dose intravenous Vitamin C (ascorbic acid) is administered early in major burn resuscitation primarily to:

Enhance wound healing through collagen synthesis
Prevent infection by boosting immune function
Reduce lipid peroxidation and decrease resuscitation fluid requirements (Correct answer)
Prevent scurvy related to nutritional deficits

Correct answer: Reduce lipid peroxidation and decrease resuscitation fluid requirements

High-dose Vitamin C (66 mg/kg/hr for 24 hours) acts as an antioxidant, reducing free radical-mediated lipid peroxidation and capillary leak, thereby decreasing fluid resuscitation requirements.

Question 102: What is a burn contracture, and which anatomical areas are most commonly affected?

Scar tissue limiting joint movement; neck and axilla are common sites (Correct answer)
Excessive granulation; the back
Fluid accumulation; the chest
Infected wound tissue; the feet

Correct answer: Scar tissue limiting joint movement; neck and axilla are common sites

A burn contracture is scar tissue that restricts joint movement; the neck and axilla are frequently affected because scars cross flexion points and pull.

Question 103: Which nutritional route is preferred for burn patients who have a functioning gastrointestinal tract?

Early enteral nutrition via nasogastric tube (Correct answer)
Peripheral parenteral nutrition
Total parenteral nutrition (TPN) via central line
Oral diet only when fully awake

Correct answer: Early enteral nutrition via nasogastric tube

Early enteral nutrition is preferred as it maintains gut integrity, reduces bacterial translocation, and supports the hypermetabolic response.

Question 104: Which condition commonly necessitates post-pyloric (nasojejunal) feeding tube placement in burn patients?

Hyperthermia
Hypertension
Opioid-induced gastroparesis or critical illness-related ileus (Correct answer)
Hypervolemia

Correct answer: Opioid-induced gastroparesis or critical illness-related ileus

Opioid-induced gastroparesis and ileus impair gastric emptying, requiring post-pyloric tube placement to continue enteral nutrition delivery.

Question 105: A patient who sustained burns in a house fire is reluctant to return home after discharge. The nurse's BEST initial response is:

Refer to psychiatry for treatment-resistant anxiety
Explore the patient's specific fears about returning home and involve the interdisciplinary team (Correct answer)
Remind the patient that the home is safe now and discharge is medically appropriate
Arrange an extended inpatient stay until the patient feels ready

Correct answer: Explore the patient's specific fears about returning home and involve the interdisciplinary team

Exploring specific fears identifies whether safety concerns, PTSD triggers, or practical barriers are driving reluctance, allowing for targeted interdisciplinary intervention.

Question 106: How frequently should ongoing assessments be conducted in Certified Burn Registered Nurse practice?

Once annually regardless of circumstances
At regular intervals based on established protocols and as conditions change (Correct answer)
Only when problems are reported
Only when required by external auditors

Correct answer: At regular intervals based on established protocols and as conditions change

Question 107: What role does calibration play in maintaining technical accuracy for Certified Burn Registered Nurse professionals?

Wait for a supervisor to notice the issue

Correct answer: Immediately secure the area and report the hazard

When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels. Delaying action increases the risk of incidents.

Question 112: Which anticoagulation strategy is most commonly used in burn patients for deep vein thrombosis (DVT) prophylaxis?

Warfarin with daily INR monitoring
Direct oral anticoagulants like rivaroxaban
Low molecular weight heparin (LMWH) such as enoxaparin (Correct answer)
Aspirin 325 mg daily alone

Correct answer: Low molecular weight heparin (LMWH) such as enoxaparin

Low molecular weight heparin (e.g., enoxaparin) is the preferred DVT prophylaxis in burn patients due to predictable pharmacokinetics, no need for frequent monitoring, and effectiveness in the hypercoagulable post-burn state.

Question 113: Which type of scar is raised, reddened, and confined to the original wound boundaries in a burn patient?

Hypertrophic scar (Correct answer)
Atrophic scar
Keloid scar
Contracture band

Correct answer: Hypertrophic scar

Hypertrophic scars are raised, erythematous, and remain within the wound margins, unlike keloids which extend beyond the original injury boundaries.

Question 114: Which route is preferred for administering fluids in severe burns?

Oral
Intramuscular
Subcutaneous
Intravenous (Correct answer)

Correct answer: Intravenous

For severe burns, the intravenous (IV) route is preferred for administering fluids because it allows for rapid and precise delivery of large volumes of fluid directly into the bloodstream. This is essential to quickly restore circulating volume and prevent hypovolemic shock. Oral or other routes would be too slow or ineffective in critical situations requiring immediate and substantial fluid replacement.

Question 115: What is the recommended glycemic target range for critically ill burn patients per current evidence-based guidelines?

80–110 mg/dL
60–100 mg/dL
200–240 mg/dL
140–180 mg/dL (Correct answer)

Correct answer: 140–180 mg/dL

Guidelines recommend 140–180 mg/dL to balance the harms of hyperglycemia and hypoglycemia, avoiding tight control due to hypoglycemia risk.

Question 116: What is a key principle in managing pain during wound care procedures?

Use distraction techniques only.
Provide analgesics prior to wound care (Correct answer)
Avoid analgesics to reduce sedation risk.
Administer analgesia after procedures.

Correct answer: Provide analgesics prior to wound care

Pain management is crucial in burn care, especially during wound care procedures which can be extremely painful. Administering analgesics prior to wound care ensures that the medication has time to take effect, reducing the patient's pain and anxiety during the procedure. This proactive approach improves patient comfort, cooperation, and overall experience, facilitating better wound care.

Question 117: What is the primary concern with total parenteral nutrition (TPN) in burn patients who cannot tolerate enteral feeding?

Electrolyte stability
Excessive weight gain
Increased infection risk and gut mucosal atrophy (Correct answer)
Hypoglycemia

Correct answer: Increased infection risk and gut mucosal atrophy

TPN bypasses the gut, leading to intestinal mucosal atrophy, bacterial translocation, and higher infection risk from central venous catheter use.

Question 118: Mafenide acetate (Sulfamylon) is preferred over silver sulfadiazine in which clinical scenario?

Deep burns with thick eschar requiring penetration (Correct answer)
Electrical burns to the extremities
Superficial partial-thickness burns in children

Contact precautions, including gown and gloves, are required to prevent MRSA transmission via direct or indirect contact.

Question 120: Which insulin-related therapy has been studied in burn patients to shift catabolism toward anabolism and support muscle protein synthesis?

Subcutaneous insulin for diabetes management
Oral hypoglycemics
Insulin infusion combined with adequate nutrition to promote anabolic metabolism (Correct answer)
Insulin sliding scale only for hyperglycemia correction

Correct answer: Insulin infusion combined with adequate nutrition to promote anabolic metabolism

Continuous insulin infusion combined with adequate nutritional support promotes glucose uptake and protein synthesis, shifting burn patients toward an anabolic state.

Question 121: When assessment results for a Certified Burn Registered Nurse evaluation are inconclusive, the BEST practice is to:

Conduct additional assessment using alternative methods (Correct answer)
Discard the results and start over completely
Report the results as definitive anyway
Delay reporting until results are favorable

Correct answer: Conduct additional assessment using alternative methods

Inconclusive results require additional assessment using alternative methods to gather more data. This triangulation approach helps clarify findings without compromising the integrity of the assessment process.

Question 122: What is the primary benefit of hydrotherapy in burn rehabilitation?

Replaces surgical debridement
Facilitates wound cleaning and range-of-motion exercises in a buoyant medium (Correct answer)
Prevents infection entirely
Eliminates need for dressing changes

Correct answer: Facilitates wound cleaning and range-of-motion exercises in a buoyant medium

Hydrotherapy allows gentle wound cleaning and range-of-motion exercises in warm water where buoyancy reduces pain and resistance during movement.

Question 123: What is the purpose of critical care monitoring in burn patients?

To minimize hospital stay.
To monitor fluid balance, organ function, and vital signs (Correct answer)
To encourage ambulation.
To maintain cosmetic appearance.

Correct answer: To monitor fluid balance, organ function, and vital signs

Critical care monitoring in burn patients is essential for continuously assessing their physiological status due to the severe systemic effects of burn injuries. This involves closely tracking fluid balance, ensuring adequate organ perfusion and function, and monitoring vital signs for any signs of deterioration or complications like shock or sepsis. This comprehensive monitoring guides treatment decisions and optimizes patient outcomes.

Question 124: Which sign indicates effective fluid resuscitation?

Low heart rate
Clear lungs
Urine output of 0.5–1 mL/kg/hr (Correct answer)
No edema

Correct answer: Urine output of 0.5–1 mL/kg/hr

Effective fluid resuscitation is best indicated by adequate urine output, typically 0.5–1 mL/kg/hr for adults. This range demonstrates that the kidneys are being adequately perfused and are able to filter waste, signifying sufficient circulating blood volume and organ perfusion. While other signs like heart rate and blood pressure are also monitored, urine output is a direct and reliable indicator of renal perfusion and overall fluid status.

Question 125: A burn nurse notices a patient is not adhering to their home exercise program. Which motivational interviewing technique is MOST appropriate?

Assign written homework about the benefits of exercise
Warn the patient about the consequences of non-adherence
Ask open-ended questions to explore the patient's own reasons for and barriers to exercise (Correct answer)
Remind the patient that the therapist's instructions must be followed

Correct answer: Ask open-ended questions to explore the patient's own reasons for and barriers to exercise

Motivational interviewing uses open-ended questions to elicit the patient's intrinsic motivation, which is more effective than external pressure or information alone.
