Wilderness First Responder (WFR) Certification Exam — Questions and Answers

Question 1: Which symptom suggests a possible spinal injury?

Rapid heart rate alone.
Mild headache.
Numbness or tingling in the extremities. (Correct answer)
Sweating and nausea.

Correct answer: Numbness or tingling in the extremities.

Numbness or tingling in the extremities is a classic symptom of a possible spinal injury because it indicates nerve impingement or damage. The spinal cord transmits sensory information, and any compromise to its function can result in altered sensations in the limbs. This neurological deficit warrants immediate spinal precautions and further assessment.

Question 2: Which finding indicates possible spinal injury in a wilderness trauma patient?

Rapid capillary refill
Tingling in extremities (Correct answer)
Sunburn on shoulders
Mild dehydration

Correct answer: Tingling in extremities

Tingling in the extremities (paresthesia) is a significant neurological symptom that can indicate nerve compression or damage, often associated with a spinal injury. The spine protects the spinal cord, which transmits nerve signals to and from the extremities. Any disruption or injury to the spinal cord can manifest as sensory changes like tingling, numbness, or weakness in the limbs.

Question 3: What is the primary role of a leader in a wilderness emergency situation?

Focus solely on patient treatment.
Take charge of all medical decisions without input.
Delegate tasks and maintain situational awareness. (Correct answer)
Wait for professional rescuers to arrive.

Correct answer: Delegate tasks and maintain situational awareness.

In a wilderness emergency, the primary role of a leader is to effectively delegate tasks, ensuring all necessary actions are taken, and to maintain situational awareness. This involves assessing the overall situation, managing resources, making decisions, and coordinating the team's efforts. A good leader empowers others while keeping the big picture in mind, rather than trying to do everything themselves.

Question 4: A hiker is found conscious but confused after a fall. During the primary assessment, after establishing responsiveness, what is the next immediate step according to the ABCDE mnemonic used in WFR training?

Assessing the level of consciousness using the AVPU scale.
Exposing and examining the patient's injuries.
Checking for a radial pulse and controlling major bleeding.
Manually stabilizing the spine and checking the airway. (Correct answer)

Correct answer: Manually stabilizing the spine and checking the airway.

In the WFR Patient Assessment System, the primary survey follows the ABCDE mnemonic: Airway, Breathing, Circulation, Disability/Decision, and Expose/Environment. After establishing responsiveness, the immediate next step is to manage the airway, especially if a spinal injury is suspected (Disability/Decision), which requires manual stabilization before proceeding.

Question 5: Which of the following scenarios is the clearest indication for immediate evacuation for a patient experiencing a sudden illness in the wilderness?

A patient with a bee sting develops a large, localized swelling and redness at the sting site but has no trouble breathing.
A diabetic patient feels weak, but after eating a granola bar, their symptoms resolve completely.
A hiker with a known seizure disorder has a single, 2-minute seizure and returns to their normal baseline mental status within 15 minutes.
A patient complains of crushing chest pain that is not relieved by rest and radiates to their left arm. (Correct answer)

Correct answer: A patient complains of crushing chest pain that is not relieved by rest and radiates to their left arm.

Crushing chest pain unrelieved by rest and radiating to the arm are classic signs of a myocardial infarction (heart attack). This is a time-sensitive medical emergency that requires immediate definitive care that is unavailable in the wilderness. The other scenarios, while requiring monitoring, do not represent the same level of immediate life threat requiring urgent evacuation. A patient returning to baseline after a typical seizure, a localized allergic reaction, and a resolved hypoglycemic event can often be managed in the field while assessing the overall situation.

Question 6: When documenting your patient encounter using the SOAP note format, what information would be included in the 'A' (Assessment) section?

Your plan to splint the injury and monitor vital signs every 15 minutes.
The patient's statement that their ankle 'is a 7 out of 10' on the pain scale.
Your field diagnosis or a list of suspected problems. (Correct answer)
The patient's heart rate is 110 bpm and their respiratory rate is 20 bpm.

Correct answer: Your field diagnosis or a list of suspected problems.

The 'A' in the SOAP note stands for Assessment. This section is where the rescuer synthesizes the subjective and objective information to form a field diagnosis or a list of potential problems. It is your professional summary of what you believe is wrong with the patient.

Question 7: Acetazolamide (Diamox) is carried by wilderness travelers primarily to prevent and treat:

Frostbite
Acute Mountain Sickness (AMS) (Correct answer)
Severe dehydration
Hypothermia

Correct answer: Acute Mountain Sickness (AMS)

Acetazolamide speeds acclimatization by stimulating breathing and reducing bicarbonate levels, lowering the risk and severity of AMS at high altitude.

Question 8: You are managing an unresponsive patient who was involved in a significant fall and you suspect a cervical spine injury. When you check for breathing, you find they are making gurgling sounds. What is the most appropriate technique to open and maintain their airway?

Jaw-thrust maneuver with spinal motion restriction. (Correct answer)
Head-tilt, chin-lift maneuver.
Performing a blind finger sweep to clear the airway.
Placing the patient in the recovery position.

Correct answer: Jaw-thrust maneuver with spinal motion restriction.

The jaw-thrust maneuver is the preferred method for opening the airway in a patient with a suspected spinal injury because it can be performed with minimal movement of the head and neck. The head-tilt, chin-lift maneuver is contraindicated as it manipulates the cervical spine. A finger sweep should only be done if a solid obstruction is visible, and the recovery position is for an uninjured, breathing patient.

Question 9: When should you initiate a rapid body survey?

When life-threatening conditions are suspected (Correct answer)
After completing a full patient history
Only for pediatric patients
When weather conditions deteriorate

Correct answer: When life-threatening conditions are suspected

A rapid body survey is a quick, head-to-toe assessment performed to identify immediate life-threatening injuries or conditions. It should be initiated when a patient has sustained significant trauma or when life-threatening conditions are suspected based on the mechanism of injury or initial assessment. This survey helps prioritize interventions and ensures critical problems are addressed without delay.

Question 10: What is the primary treatment for anaphylaxis in a wilderness setting?

Waiting to see if symptoms worsen.
Oral antihistamines alone.
Elevating the legs and drinking water.
Immediate epinephrine injection (if available). (Correct answer)

Correct answer: Immediate epinephrine injection (if available).

The primary and most effective treatment for anaphylaxis in any setting, including the wilderness, is an immediate epinephrine injection. Epinephrine rapidly constricts blood vessels, relaxes airway muscles, and reduces swelling, counteracting the life-threatening allergic reaction. Oral antihistamines are insufficient for severe anaphylaxis and should not delay epinephrine administration.

Question 11: What is the best way to control severe bleeding in the wilderness?

Elevating the limb without pressure.
Applying a tourniquet immediately.
Applying firm, direct pressure with a sterile dressing. (Correct answer)
Using a cold compress to slow blood flow.

Correct answer: Applying firm, direct pressure with a sterile dressing.

The most effective initial method to control severe bleeding in the wilderness is applying firm, direct pressure with a sterile dressing. This direct compression helps to close the damaged blood vessels and promote clotting. While tourniquets are used for uncontrolled bleeding, direct pressure is the primary and often sufficient first-line intervention.

Question 12: What does the 'A' stand for in the AVPU scale?

Airway
Alert (Correct answer)
Ambulatory
Arterial

Correct answer: Alert

The AVPU scale is a rapid assessment tool used to determine a patient's level of consciousness. The 'A' in AVPU stands for Alert, indicating that the patient is awake, aware of their surroundings, and can spontaneously open their eyes and respond. This is the highest level of consciousness on the scale, signifying good neurological function.

Question 13: Which pulse point is most reliable for assessing circulation in cold environments?

Radial pulse
Dorsalis pedis pulse
Carotid pulse (Correct answer)
Femoral pulse

Correct answer: Carotid pulse

Extremity pulses may be weak in hypothermic patients.

Question 14: A patient is stung by a bee and quickly develops a single, large (4-inch diameter), swollen, red, and intensely itchy wheal at the sting site. The patient is breathing normally, denies any throat tightness, and has no other signs or symptoms. This is best classified as:

Anaphylactic shock.
A severe local allergic reaction. (Correct answer)
A toxic venom reaction.
A mild local reaction.

Correct answer: A severe local allergic reaction.

This is a severe local allergic reaction. Although the reaction is large and uncomfortable, it is confined to the area of the sting. Anaphylaxis is a life-threatening systemic reaction that must involve two or more body systems (e.g., skin and respiratory, or skin and cardiovascular). Since this patient's respiratory and cardiovascular systems are unaffected, it is not anaphylaxis.

Question 15: Which of the following statements best describes a primary difference in the approach to Cardiopulmonary Resuscitation (CPR) in a wilderness versus an urban setting?

Rescue breaths are not performed in the wilderness due to the high risk of disease transmission.
In the wilderness, rescuers may have specific protocols to stop CPR after a set period if resuscitation is futile. (Correct answer)
The ratio of chest compressions to breaths is changed from 30:2 to 15:2 in the wilderness.
Chest compressions are performed at a slower rate (80/min) in the wilderness to conserve rescuer energy.

Correct answer: In the wilderness, rescuers may have specific protocols to stop CPR after a set period if resuscitation is futile.

Due to prolonged transport times and limited resources, wilderness medicine protocols include specific criteria for terminating resuscitation efforts (e.g., after 30 minutes of CPR without a return of spontaneous circulation in certain non-hypothermic situations). In an urban setting, CPR is almost always continued until care is transferred to a higher medical authority. The compression-to-breath ratio and rate remain the same (30:2 at 100-120/min), and rescue breaths are a critical component of CPR.

Question 16: Which of the following is a key symptom of a head injury requiring urgent evacuation?

Confusion or worsening headache. (Correct answer)
Mild dizziness after standing.
Temporary blurred vision.
Minor scalp bleeding.

Correct answer: Confusion or worsening headache.

Confusion or a worsening headache are critical symptoms of a head injury that indicate increasing intracranial pressure or brain swelling, requiring urgent evacuation. These neurological changes suggest a deteriorating condition and potential for serious complications like herniation. Any alteration in mental status or severe, progressive headache after head trauma warrants immediate higher-level medical care.

Question 17: When treating a patient for severe hypothermia in a wilderness setting, which action is most appropriate?

Provide hot liquids like coffee or tea to drink.
Rub the patient's extremities vigorously to restore circulation.
Handle the patient gently and place them in a hypothermia wrap with heat packs on the core. (Correct answer)
Encourage the patient to walk around to generate heat.

Correct answer: Handle the patient gently and place them in a hypothermia wrap with heat packs on the core.

Patients with severe hypothermia have a cold, irritable myocardium (heart muscle) and must be handled with extreme care to prevent cardiac arrest. The priority is to prevent further heat loss and gently rewarm the core. This is best accomplished by creating a hypothermia wrap (layering insulation and a vapor barrier) and applying external heat sources, like hot water bottles or chemical heat packs, to the core areas (chest, back, axillae). Vigorous movement, rubbing extremities, or providing oral fluids to a severely hypothermic patient can be dangerous.

Question 18: Which of the following is a sign of heat stroke (a life-threatening emergency)?

Profuse sweating and cool skin.
Confusion and lack of sweating. (Correct answer)
Mild muscle cramps.
Normal body temperature.

Correct answer: Confusion and lack of sweating.

Heat stroke is a life-threatening emergency characterized by a dangerously elevated core body temperature and central nervous system dysfunction. Key signs include confusion, altered mental status, and often a lack of sweating (anhidrosis) because the body's thermoregulatory mechanism has failed. Unlike heat exhaustion, profuse sweating is typically absent in heat stroke.

Question 19: Which of the following best describes the correct Wilderness First Responder protocol for removing an embedded tick?

Cover the tick with petroleum jelly or essential oil to make it back out.
Touch the tick with a recently extinguished hot match to shock it into releasing.
Use fine-tipped tweezers to grasp the tick's body and twist it counter-clockwise.
Use fine-tipped tweezers to grasp the tick as close to the skin as possible and pull upward with steady, even pressure. (Correct answer)

Correct answer: Use fine-tipped tweezers to grasp the tick as close to the skin as possible and pull upward with steady, even pressure.

The recommended method is to use fine-tipped tweezers to grasp the tick's head/mouth-parts as close to the skin as possible and pull straight out without twisting or jerking. Methods like smothering it with petroleum jelly, twisting, or using heat are not recommended because they can agitate the tick, potentially causing it to regurgitate infectious fluids into the bite wound.

Question 20: A patient in the backcountry is experiencing a severe asthma attack with audible wheezing. Which medication is most appropriate as first-line treatment?

Epinephrine auto-injector (EpiPen)
Albuterol inhaler (Correct answer)
Ibuprofen
Diphenhydramine (Benadryl)

Correct answer: Albuterol inhaler

Albuterol is a short-acting beta-2 agonist that directly relaxes bronchial smooth muscle, making it the first-line drug for acute bronchospasm in asthma.

Question 21: What is the first step in treating mild hypothermia in the wilderness?

Massage the patient's extremities.
Encourage vigorous exercise to generate heat.
Remove wet clothing and replace with dry layers. (Correct answer)
Give the patient hot coffee or alcohol.

Correct answer: Remove wet clothing and replace with dry layers.

The first and most critical step in treating mild hypothermia is to remove any wet clothing and replace it with dry layers. Wet clothing rapidly conducts heat away from the body through evaporation and conduction, exacerbating heat loss. Removing it stops this ongoing heat loss and allows the patient to begin rewarming more effectively.

Question 22: How should you communicate with a panicked team member during a rescue?

Give them a simple, direct task to focus on. (Correct answer)
Yell to snap them out of it.
Send them away from the scene.
Ignore them to avoid escalating the situation.

Correct answer: Give them a simple, direct task to focus on.

When a team member is experiencing panic, providing a simple, direct, and achievable task can help redirect their focus and regain control. This gives them something concrete to concentrate on, breaking the cycle of panic and allowing them to contribute constructively. It helps to ground them and restore a sense of purpose and capability.

Question 23: What is the 'Rule of Threes' for survival priorities?

3 days without water, 3 weeks without food.
3 miles to safety, 3 people needed for rescue.
3 hours without sleep, 3 days without social contact.
3 minutes without air, 3 hours without shelter (in extreme conditions). (Correct answer)

Correct answer: 3 minutes without air, 3 hours without shelter (in extreme conditions).

The 'Rule of Threes' is a common survival guideline that prioritizes immediate threats to life. It states that a person can survive approximately 3 minutes without air, 3 hours without shelter in extreme conditions (like severe cold), 3 days without water, and 3 weeks without food. This rule emphasizes the critical importance of addressing breathing and shelter first in a survival situation.

Question 24: What is the first step in wilderness patient assessment?

Check for medical alert tags
Assess the scene for safety (Correct answer)
Begin CPR immediately
Take a full patient history

Correct answer: Assess the scene for safety

Initial assessment focuses on identifying immediate life threats in remote environments.

Question 25: When should you initiate an emergency evacuation for a patient?

When the patient's condition is life-threatening or beyond field care. (Correct answer)
After attempting all possible field treatments.
For any minor injury to prevent complications.
Only when the patient requests it.

Correct answer: When the patient's condition is life-threatening or beyond field care.

Emergency evacuation is a serious decision reserved for situations where a patient's life is in immediate danger or their injuries/illness exceed the capabilities of wilderness first aid. Attempting to manage critical conditions in the field when advanced medical care is needed can lead to worse outcomes. Therefore, evacuation is initiated when the patient's condition is life-threatening or beyond the scope of field treatment.

Question 26: How do you treat a patient with severe dehydration in the wilderness?

Offer only caffeinated drinks.
Withhold fluids to prevent vomiting.
Give small sips of electrolyte solution or clean water. (Correct answer)
Have the patient eat snow to rehydrate.

Correct answer: Give small sips of electrolyte solution or clean water.

For severe dehydration, gradual rehydration is key to prevent complications like vomiting or electrolyte imbalance. Giving small, frequent sips of an electrolyte solution or clean water allows the body to absorb fluids effectively without overwhelming the system. This approach helps to slowly restore fluid and electrolyte balance, which is safer and more effective than rapid intake.

Question 27: Oral rehydration salts (ORS) are superior to plain water during dehydration primarily because they:

Provide high caloric content to prevent hypoglycemia
Contain antiemetic compounds to suppress vomiting
Are sterile and free of waterborne contaminants
Contain electrolytes that activate co-transport mechanisms to enhance intestinal fluid absorption (Correct answer)

Correct answer: Contain electrolytes that activate co-transport mechanisms to enhance intestinal fluid absorption

ORS contains balanced sodium, glucose, and potassium that engage sodium-glucose co-transporters in the intestine, dramatically increasing fluid absorption compared to water alone.

Question 28: Ibuprofen should generally be avoided in a wilderness patient who is:

Running a mild fever below 101°F
Taking vitamin C supplements
Experiencing mild muscle soreness 24 hours after injury
Moderately dehydrated with poor peripheral perfusion (Correct answer)

Correct answer: Moderately dehydrated with poor peripheral perfusion

NSAIDs reduce renal blood flow via prostaglandin inhibition, significantly increasing the risk of acute kidney injury in a volume-depleted patient.

Question 29: How should you treat a snakebite from an unidentified venomous snake in the field?

Apply a tight tourniquet above the bite.
Cut the wound and suck out the venom.
Apply ice directly to the bite.
Immobilize the limb and keep it below heart level. (Correct answer)

Correct answer: Immobilize the limb and keep it below heart level.

For an unidentified venomous snakebite, the best field treatment is to immobilize the bitten limb and keep it at or below heart level. Immobilization helps slow the spread of venom through the lymphatic system, while keeping it below heart level reduces blood flow to the area, further limiting systemic absorption. Avoid methods like cutting, sucking, or applying ice/tourniquets, as these are harmful or ineffective.

Question 30: A trail runner in a long-distance race is disoriented, nauseous, and has a severe headache after drinking large amounts of water at every aid station. They have clear urine and have not been eating salty snacks. What is the most likely diagnosis, and what is the appropriate field treatment?

Hypoglycemia; give a large amount of sugar immediately.
Severe Dehydration; give more water and electrolytes immediately.
Exertional Hyponatremia; restrict fluids and give salty foods. (Correct answer)
Heat Stroke; immediately and aggressively cool the patient.

Correct answer: Exertional Hyponatremia; restrict fluids and give salty foods.

This patient's symptoms, combined with a history of excessive water intake and low salt consumption, strongly suggest Exertional Hyponatremia. This is a dangerous condition where excessive fluid intake dilutes blood sodium levels. The correct field management is to stop all fluid intake and provide salty foods to help restore sodium balance. Giving more fluids would worsen the condition.

Question 31: Ondansetron (Zofran) is most useful in the wilderness for controlling:

Nausea and vomiting (Correct answer)
Anxiety and agitation
Pain from fractures
Diarrhea and cramping

Correct answer: Nausea and vomiting

Ondansetron blocks 5-HT3 receptors to suppress nausea and vomiting, allowing the patient to stay hydrated and take oral medications.

Question 32: Which of the following patient conditions presents the MOST urgent need for an immediate and rapid evacuation from a wilderness setting?

A closed, angulated tibia fracture with good distal circulation, sensation, and motion (CSM).
Signs and symptoms of severe hypothermia, including lethargy and cessation of shivering. (Correct answer)
A large laceration on the thigh where bleeding has been controlled with a pressure dressing.
A simple shoulder dislocation in an otherwise healthy and alert individual.

Correct answer: Signs and symptoms of severe hypothermia, including lethargy and cessation of shivering.

Severe hypothermia with a decreasing level of consciousness is an immediate life-threat that cannot be definitively managed in the field. This condition requires rapid evacuation to a hospital for advanced rewarming. While the other conditions are serious, they are either stable (controlled bleeding, simple dislocation) or can be managed with splinting before a more controlled evacuation.

Question 33: A backcountry patient develops symptoms consistent with a urinary tract infection. Which class of medication would appropriately address the underlying cause?

Antihistamines
Antifungals
NSAIDs for symptom control only
Antibiotics (Correct answer)

Correct answer: Antibiotics

UTIs are caused by bacteria and require antibiotic treatment; WFR scope may include trimethoprim-sulfamethoxazole or ciprofloxacin for such field situations.

Question 34: You are assessing a patient who is shivering uncontrollably and has pale, cool skin. In the WFR Patient Assessment System, under which part of the secondary assessment would you primarily record these observations?

Chief Complaint
Mechanism of Injury
Vital Signs (Correct answer)
SAMPLE History

Correct answer: Vital Signs

Vital signs in a wilderness context include assessing the patient's skin color, temperature, and moisture (SCTM), along with Level of Responsiveness (LOR), Heart Rate (HR), and Respiratory Rate (RR). Shivering and pale, cool skin are key observations related to the patient's circulatory and thermoregulatory status, which are documented as part of the vital signs assessment.

Question 35: What is a key component of effective debriefing after a rescue operation?

Skipping the debrief to save time.
Assigning blame for mistakes.
Discussing lessons learned without judgment. (Correct answer)
Only praising the team leader.

Correct answer: Discussing lessons learned without judgment.

An effective debriefing focuses on learning and improvement rather than assigning blame. It provides a safe, non-judgmental space for team members to share observations, discuss what went well, what could be improved, and identify lessons learned from the operation. This process fosters continuous growth, enhances team cohesion, and improves future performance.

Question 36: Which of the following is the most critical and defining sign that differentiates heat stroke from heat exhaustion?

Nausea and vomiting
Altered mental status (Correct answer)
Heavy sweating
A rapid, weak pulse

Correct answer: Altered mental status

The key differentiator between heat exhaustion and the more severe, life-threatening heat stroke is a change in mental status. A person with heat stroke will exhibit confusion, irrational behavior, combativeness, or may lose consciousness, indicating the body's thermoregulatory system has failed and the brain is being affected. While other signs overlap, a significant change in mental function is the hallmark of heat stroke and signals a true medical emergency.

Question 37: How often should you reassess vital signs in a stable wilderness patient?

Only at initial assessment
Every 2-4 hours (Correct answer)
Every 15-30 minutes
When evacuation arrives

Correct answer: Every 2-4 hours

For a stable patient in a wilderness setting, reassessing vital signs every 2-4 hours is generally appropriate to monitor for any changes in their condition. While more frequent checks are needed for unstable patients, a stable patient still requires regular monitoring due to the dynamic nature of injuries and illnesses, and the challenging wilderness environment. This allows for early detection of deterioration without over-taxing resources.

Question 38: What is the most common sign of hypovolemic shock in trauma patients?

Slow, deep breathing.
Pink, warm skin.
Hypertension (high blood pressure).
Rapid, weak pulse. (Correct answer)

Correct answer: Rapid, weak pulse.

Hypovolemic shock results from significant fluid (blood) loss, causing the heart to pump faster to compensate for the decreased circulating volume. A rapid, weak (thready) pulse is the most common and earliest sign, as the heart struggles to maintain perfusion with less blood. This indicates the body's compensatory mechanisms are working but are becoming overwhelmed.

Question 39: During a scene size-up in a wilderness environment, what is the FIRST and most critical priority for a Wilderness First Responder?

Ensuring the safety of the rescuer and the group. (Correct answer)
Determining the mechanism of injury (MOI) for the patient.
Checking the patient's airway, breathing, and circulation (ABCs).
Immediately beginning documentation on a SOAP note.

Correct answer: Ensuring the safety of the rescuer and the group.

The absolute first priority in any rescue situation is to ensure the scene is safe for the rescuer, bystanders, and then the patient. Approaching an unsafe scene can result in more casualties, including the rescuer. All other steps of the patient assessment system follow after confirming scene safety.

Question 40: When should a tourniquet be applied in wilderness trauma care?

Only in a hospital setting.
For any bleeding to reduce infection risk.
When direct pressure fails to stop severe bleeding. (Correct answer)
For minor cuts to speed healing.

Correct answer: When direct pressure fails to stop severe bleeding.

A tourniquet should be applied in wilderness trauma care only when direct pressure and pressure dressings have failed to control severe, life-threatening bleeding from an extremity. Tourniquets are powerful tools that can save a life, but they carry risks of tissue damage, so they are reserved for situations where other methods are insufficient to stop hemorrhage.

Question 41: What is the priority when treating a wilderness patient with severe bleeding?

Checking blood sugar levels
Splinting fractures
Direct pressure to stop bleeding (Correct answer)
Administering pain medication

Correct answer: Direct pressure to stop bleeding

In wilderness first aid, controlling severe bleeding is a top priority because significant blood loss can quickly lead to hypovolemic shock and death. Applying direct pressure to the wound with a clean dressing is the most effective initial method to stop or slow blood flow. This action helps preserve the patient's circulating blood volume and is critical for survival.

Question 42: Which of the following components is part of the secondary assessment in the Wilderness First Responder Patient Assessment System?

Performing a scene size-up for hazards.
Obtaining a SAMPLE history from the patient. (Correct answer)
Opening the patient's airway using a jaw-thrust maneuver.
Controlling life-threatening external hemorrhage.

Correct answer: Obtaining a SAMPLE history from the patient.

The secondary assessment occurs after the primary assessment has ruled out or managed immediate life threats. It involves a more detailed examination, which includes obtaining a SAMPLE history (Signs/Symptoms, Allergies, Medications, Pertinent history, Last oral intake, Events leading to injury), taking vital signs, and performing a head-to-toe physical exam.

Question 43: A member of your group on a multi-day backpacking trip at 11,000 ft begins to show signs of ataxia, confusion, and a severe headache. These symptoms are most indicative of which altitude-related illness?

Acute Mountain Sickness (AMS)
High Altitude Cerebral Edema (HACE) (Correct answer)
Dehydration
High Altitude Pulmonary Edema (HAPE)

Correct answer: High Altitude Cerebral Edema (HACE)

High Altitude Cerebral Edema (HACE) is a life-threatening condition characterized by swelling of the brain. The hallmark signs are neurological, including ataxia (loss of coordination), confusion, and altered mental status, often accompanied by a severe headache. While AMS precedes HACE, the presence of these specific neurological deficits indicates progression to the more severe HACE, which requires immediate descent.

Question 44: How should you manage an open chest wound (sucking chest wound) in the field?

Apply a standard bandage without sealing.
Pack the wound with gauze to stop bleeding.
Cover it tightly with plastic and tape on three sides. (Correct answer)
Leave it open to air.

Correct answer: Cover it tightly with plastic and tape on three sides.

An open chest wound, or sucking chest wound, allows air to enter the pleural space, leading to a pneumothorax. To manage this, apply an occlusive dressing (like plastic wrap) and tape it on three sides. This creates a flutter valve, allowing air to escape during exhalation but preventing more air from entering during inhalation, which helps to re-expand the lung and prevent tension pneumothorax.

Question 45: When managing a musculoskeletal injury like a sprained ankle in a remote wilderness setting, the acronym RICE (Rest, Ice, Compression, Elevation) is often recommended. What is the primary purpose of the 'Ice' component in the initial hours after the injury?

To accelerate the healing process by increasing blood flow.
To prevent infection in any associated abrasions.
To diagnose the severity of the ligament damage.
To reduce pain and control swelling. (Correct answer)

Correct answer: To reduce pain and control swelling.

In the context of the RICE protocol for acute soft tissue injuries, applying ice (or a cold pack) serves to constrict blood vessels, which helps to control swelling and inflammation. It also has an analgesic effect, numbing the area and reducing pain. While other protocols like MEAT and POLICE exist, the function of cold therapy in the immediate aftermath of an injury is primarily for pain and swelling management.

Question 46: A fellow backpacker suddenly collapses, becomes rigid, and begins to convulse. The seizure lasts for approximately 90 seconds. After the convulsions stop, the patient is groggy and disoriented. Which of the following is NOT an appropriate action in managing this patient?

Placing the patient in the recovery position after the convulsions cease.
Moving objects away to protect the patient from injury during the seizure.
Timing the duration of the seizure and monitoring their breathing.
Placing a bite stick or wallet in the patient's mouth to prevent them from biting their tongue. (Correct answer)

Correct answer: Placing a bite stick or wallet in the patient's mouth to prevent them from biting their tongue.

During a seizure, the primary goal is to protect the patient from harm. This involves clearing the area of dangerous objects and cushioning their head. However, you should never force anything into the patient's mouth. This can cause broken teeth, jaw injuries, or an airway obstruction. Timing the seizure and placing them in a recovery position afterward to manage the airway are both appropriate and important actions.

Question 47: A climber falls and complains of severe pain in their lower leg. The leg is obviously deformed. After completing the primary survey and confirming no immediate life threats, you begin the secondary assessment. What is the most appropriate first step for assessing the injured leg?

Administer pain medication before any further assessment.
Immediately splint the leg in the position found.
Ask the patient to stand and see if they can bear weight.
Check for Circulation, Sensation, and Movement (CSM) distal to the injury. (Correct answer)

Correct answer: Check for Circulation, Sensation, and Movement (CSM) distal to the injury.

During the head-to-toe physical exam of the secondary assessment, it is crucial to check for Circulation, Sensation, and Movement (CSM) in all extremities, especially distal to a known injury. This helps determine if blood flow and nerve function are compromised, which is a critical finding that influences treatment and evacuation urgency.

Question 48: What is the first priority when assessing a trauma patient in the wilderness?

Asking about allergies.
Checking for broken bones.
Assessing the ABCs (Airway, Breathing, Circulation). (Correct answer)
Elevating the legs to prevent shock.

Correct answer: Assessing the ABCs (Airway, Breathing, Circulation).

When assessing any trauma patient, especially in the wilderness, the absolute first priority is to assess and manage the ABCs: Airway, Breathing, and Circulation. Ensuring a patent airway, adequate breathing, and effective circulation addresses the most immediate life threats. Without these basic functions, other interventions will be ineffective, making them the foundation of all trauma care.

Question 49: Which of the following is a critical component of a focused spine assessment (FSA) used to 'clear' a spine in the wilderness?

The patient must be reliable, cooperative, sober, and alert. (Correct answer)
The patient reports a complete absence of any pain anywhere in their body.
The patient must be able to walk at least 10 feet without assistance.
The mechanism of injury must be minor, such as a ground-level fall.

Correct answer: The patient must be reliable, cooperative, sober, and alert.

A reliable patient is the cornerstone of a focused spine assessment. The patient must be able to understand questions, follow commands, and accurately report sensations. If a patient is altered (due to head injury, intoxication, extreme temperature, etc.), they cannot be considered reliable, and their spine cannot be cleared in the field. The assessment also checks for pain/tenderness on the spine and normal motor/sensory function, but reliability is the essential first step.

Question 50: Which technique helps assess for potential internal bleeding?

Monitoring for tachycardia and hypotension (Correct answer)
Assessing skin turgor
Testing grip strength
Checking pupil response

Correct answer: Monitoring for tachycardia and hypotension

Internal bleeding can be difficult to detect externally, but it often leads to hypovolemic shock. Monitoring for tachycardia (rapid heart rate) and hypotension (low blood pressure) is crucial because these are key signs of the body compensating for significant blood loss. The heart beats faster to circulate remaining blood, and blood pressure drops as volume decreases, indicating potential internal hemorrhage.

Question 51: Which of the following is a sign of tension pneumothorax?

Tracheal deviation away from the affected side. (Correct answer)
Normal oxygen saturation levels.
Equal chest rise with breathing.
Decreased breath sounds on the affected side.

Correct answer: Tracheal deviation away from the affected side.

Tension pneumothorax is a life-threatening condition where air accumulates in the pleural space, compressing the lung and shifting the mediastinum. Tracheal deviation away from the affected side is a late but critical sign, indicating significant pressure buildup that is pushing the trachea and other mediastinal structures. This shift compromises heart and lung function, requiring immediate intervention.

Question 52: You are treating a severely hypothermic patient who goes into cardiac arrest. An AED is available. After delivering the first shock, the patient remains in a shockable rhythm. What is the most appropriate next action regarding the AED?

Increase the shock energy on the AED before delivering the next shock.
Do not deliver any more shocks until the patient has been actively rewarmed to 86° F (30° C).
Deliver a second shock immediately without performing CPR in between.
Continue to follow the AED's prompts for analysis and shocks while performing high-quality CPR. (Correct answer)

Correct answer: Continue to follow the AED's prompts for analysis and shocks while performing high-quality CPR.

Current wilderness medicine and AHA guidelines recommend following standard AED protocols even for hypothermic patients. This means continuing high-quality CPR and following the AED's prompts for analysis and shocks as they are indicated. While older protocols suggested limiting shocks, modern guidance emphasizes treating a shockable rhythm as it is detected, concurrently with rewarming efforts.
