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

Question 1: Which of the following is a critical component of a focused spine assessment (FSA) used to 'clear' a spine in the wilderness?

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

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 2: 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?

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

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 3: Epinephrine auto-injectors (EpiPens) are primarily used in wilderness medicine to treat which condition?

Cardiac arrest
Anaphylaxis (Correct answer)
Severe asthma only
Diabetic emergencies

Correct answer: Anaphylaxis

Epinephrine is the first-line treatment for anaphylaxis, rapidly reversing bronchospasm, vasodilation, and hypotension caused by a severe allergic reaction.

Question 4: Which of the following is NOT one of the classic 'five rights' of medication administration?

Right patient and right drug
Right dose and right route
Right insurance authorization (Correct answer)
Right time of administration

Correct answer: Right insurance authorization

The five rights are: right patient, right drug, right dose, right route, and right time — insurance authorization is not part of this safety framework.

Question 5: When documenting your patient encounter using the SOAP note format, what information would be included in the 'A' (Assessment) section?

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

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 6: When should you initiate a rapid body survey?

After completing a full patient history
Only for pediatric patients
When life-threatening conditions are suspected (Correct answer)
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 7: Which symptom suggests a possible spinal injury?

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

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 8: 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.
Placing a bite stick or wallet in the patient's mouth to prevent them from biting their tongue. (Correct answer)
Timing the duration of the seizure and monitoring their breathing.

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 9: Which over-the-counter medication provides pain relief, fever reduction, AND anti-inflammatory effects, making it especially useful for musculoskeletal injuries in the wilderness?

Ibuprofen (Advil/Motrin) (Correct answer)
Diphenhydramine (Benadryl)
Acetaminophen (Tylenol)
Loperamide (Imodium)

Correct answer: Ibuprofen (Advil/Motrin)

Ibuprofen is an NSAID that provides analgesia, antipyresis, and anti-inflammation, making it the most versatile OTC choice for sprains, strains, and similar injuries.

Question 10: Which of the following components is part of the secondary assessment in the Wilderness First Responder Patient Assessment System?

Opening the patient's airway using a jaw-thrust maneuver.
Performing a scene size-up for hazards.
Obtaining a SAMPLE history from the patient. (Correct answer)
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 11: What is the first step in wilderness patient assessment?

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

Correct answer: Assess the scene for safety

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

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

Arterial
Alert (Correct answer)
Airway
Ambulatory

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

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

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

Direct pressure to stop bleeding (Correct answer)
Splinting fractures
Checking blood sugar levels
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 15: How should you manage an open chest wound (sucking chest wound) in the field?

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

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 16: What is the primary cause of altitude sickness?

Physical exhaustion.
Dehydration alone.
Exposure to cold temperatures.
Low oxygen levels at high elevation. (Correct answer)

Correct answer: Low oxygen levels at high elevation.

Altitude sickness is primarily caused by the reduced atmospheric pressure at high elevations, which results in lower partial pressure of oxygen (hypoxia). This means there is less oxygen available for the body to absorb with each breath. The body struggles to adapt to this oxygen deprivation, leading to symptoms like headache, nausea, and fatigue.

Question 17: Which of the following statements best describes a primary difference in the approach to Cardiopulmonary Resuscitation (CPR) in a wilderness versus an urban setting?

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.
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)

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 18: A member of your party spills boiling water on their hand while cooking. The skin is red, painful, and has formed several small blisters. After stopping the burning process, what is the immediate and most critical treatment?

Wrap the hand tightly in a compression bandage to prevent swelling.
Apply a thick layer of antibiotic ointment immediately.
Pop the blisters to release the fluid and reduce pressure.
Cool the burn with cool (not ice-cold) water for at least 20 minutes. (Correct answer)

Correct answer: Cool the burn with cool (not ice-cold) water for at least 20 minutes.

The immediate and most important first aid for a thermal burn is to stop the burning process by cooling the area. This should be done with cool running water or compresses for a minimum of 20 minutes if possible. This action limits the depth of the burn and provides significant pain relief. Applying ointments immediately can trap heat. Tight bandages are inappropriate, and blisters should generally be left intact as they provide a sterile barrier.

Question 19: 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?

Immediately splint the leg in the position found.
Ask the patient to stand and see if they can bear weight.
Administer pain medication before any further assessment.
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 20: A patient has a suspected closed fracture of their forearm. Which of the following describes the most appropriate improvised splinting technique?

Tightly lashing a single, large tree branch to the top of the forearm.
Placing the arm in a sling without any additional rigid support.
Encasing the entire arm and hand in a thick layer of mud to create a natural cast.
Using a rolled-up sleeping pad and two trekking poles to create a rigid 'sandwich' splint, secured with straps. (Correct answer)

Correct answer: Using a rolled-up sleeping pad and two trekking poles to create a rigid 'sandwich' splint, secured with straps.

A good improvised splint should be well-padded, rigid, and immobilize the joints above and below the injury. Using a sleeping pad for padding and two rigid trekking poles on either side of the forearm creates a strong 'sandwich' splint. A single branch provides poor immobilization. A sling alone is insufficient for a forearm fracture as it doesn't immobilize the wrist and elbow effectively. A mud cast would be ineffective and potentially harmful.

Question 21: What is the standard adult oral dose of diphenhydramine (Benadryl) for treating mild allergic reactions in the field?

150 mg
25–50 mg (Correct answer)
75–100 mg
12.5 mg

Correct answer: 25–50 mg

The standard adult dose of diphenhydramine is 25–50 mg, effectively controlling mild allergic symptoms without risking toxicity.

Question 22: Ondansetron (Zofran) is most useful in the wilderness for controlling:

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

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

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

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

Sunburn on shoulders
Rapid capillary refill
Tingling in extremities (Correct answer)
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 25: When packaging a patient with a suspected spinal injury in a litter for a long evacuation, what is the primary purpose of creating an "X" pattern with webbing straps over the patient's torso?

To provide compression to the chest in case of rib fractures.
To act as a pelvic binder for a suspected pelvic fracture.
To serve as the primary lifting points for the patient.
To prevent the patient from sliding up or down within the litter on inclines and declines. (Correct answer)

Correct answer: To prevent the patient from sliding up or down within the litter on inclines and declines.

The diagonal or "X" strapping pattern is crucial for securing the patient's torso to the litter and preventing longitudinal (up and down) movement. This is especially important for a patient with a potential spinal injury when the litter is tilted during an evacuation over steep terrain.

Question 26: What is the most common sign of hypovolemic shock in trauma patients?

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

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 27: Loperamide (Imodium) is used in wilderness medicine primarily to manage:

Diarrhea (Correct answer)
Dehydration from heat stroke
Altitude sickness
Nausea and vomiting

Correct answer: Diarrhea

Loperamide slows intestinal motility to reduce diarrhea, preventing dangerous fluid and electrolyte losses in a remote environment.

Question 28: Which medication is contraindicated in patients with suspected gastrointestinal bleeding or peptic ulcer disease?

Ibuprofen (Correct answer)
Diphenhydramine
Acetaminophen
Ondansetron

Correct answer: Ibuprofen

Ibuprofen inhibits prostaglandins that protect the stomach lining and impairs platelet aggregation, worsening GI bleeding and ulcers.

Question 29: When should you initiate an emergency evacuation for a patient?

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

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

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

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

Elevating the limb without pressure.
Applying firm, direct pressure with a sterile dressing. (Correct answer)
Applying a tourniquet immediately.
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 32: When should a tourniquet be applied in wilderness trauma care?

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

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 33: What is the purpose of a 'go/no-go' decision point in rescue planning?

To eliminate the need for contingency plans.
To reassess risks and continue or abort the mission. (Correct answer)
To switch team leaders mid-operation.
To delay the rescue until conditions improve.

Correct answer: To reassess risks and continue or abort the mission.

A 'go/no-go' decision point is a critical safety measure in rescue planning, representing a pre-determined moment to pause and re-evaluate the mission. At this point, the team reassesses current conditions, risks, resources, and the patient's status against the mission's objectives. This allows for an informed decision to either proceed safely or abort the operation if conditions are too hazardous.

Question 34: Which pulse point is most reliable for assessing circulation in cold environments?

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

Correct answer: Carotid pulse

Extremity pulses may be weak in hypothermic patients.

Question 35: What is the first priority when assessing a trauma patient in the wilderness?

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

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

Handle the patient gently and place them in a hypothermia wrap with heat packs on the core. (Correct answer)
Rub the patient's extremities vigorously to restore circulation.
Provide hot liquids like coffee or tea to drink.
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 37: Which plant is safest to consume in a survival situation if you're unsure of its edibility?

Brightly colored berries.
Plants with milky sap.
Mushrooms with gills.
Only plants you can positively identify as safe. (Correct answer)

Correct answer: Only plants you can positively identify as safe.

In a survival situation, consuming unidentified plants is extremely dangerous due to the high risk of poisoning. Many toxic plants closely resemble edible ones, making positive identification the only safe approach to foraging. Relying solely on positively identified safe plants prevents severe illness, gastrointestinal distress, or even death.

Question 38: What is the primary treatment for anaphylaxis in a wilderness setting?

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

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

Take charge of all medical decisions without input.
Delegate tasks and maintain situational awareness. (Correct answer)
Focus solely on patient treatment.
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 40: During a scene size-up in a wilderness environment, what is the FIRST and most critical priority for a Wilderness First Responder?

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

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 41: Which of the following is a sign of tension pneumothorax?

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

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

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

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 43: Two days after sustaining a cut on the leg, a patient complains of increasing pain. You observe that the skin around the wound is red, swollen, and warm to the touch. What do these signs most strongly indicate?

The formation of a deep hematoma.
A normal healing process.
An allergic reaction to the bandage.
A developing wound infection. (Correct answer)

Correct answer: A developing wound infection.

The classic signs of a localized soft tissue infection are redness (erythema), swelling (edema), increased warmth, and pain. The presence of pus or foul-smelling drainage would further confirm this. While some minor redness is part of normal healing, the combination of these signs, particularly worsening pain and warmth, strongly suggests an infection that requires cleaning, drainage, and monitoring for evacuation.

Question 44: 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?

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

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 45: 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?

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

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

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

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 47: The standard adult epinephrine auto-injector (EpiPen) delivers which dose intramuscularly?

0.1 mg
0.3 mg (Correct answer)
0.5 mg
1.0 mg

Correct answer: 0.3 mg

The standard adult EpiPen delivers 0.3 mg of epinephrine IM into the lateral thigh, the established dose for treating anaphylaxis.

Question 48: What is the first step in treating mild hypothermia in the wilderness?

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

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 49: 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?

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

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 50: What is the primary consideration when deciding to evacuate a wilderness patient?

Potential for condition to worsen in current environment (Correct answer)
Patient's insurance coverage
Time of day
Availability of cell service

Correct answer: Potential for condition to worsen in current environment

The primary consideration when deciding to evacuate a wilderness patient is the potential for their condition to worsen or become life-threatening in the current environment. Wilderness environments lack advanced medical care, and delays can exacerbate injuries or illnesses. If the patient's needs exceed the available resources or their condition is unstable, evacuation becomes critical to ensure access to definitive medical treatment.

Question 51: Acetaminophen (Tylenol) should be used with caution or avoided in patients who:

Have a history of kidney stones
Consume alcohol regularly or have liver disease (Correct answer)
Are allergic to sulfa drugs
Have a history of asthma

Correct answer: Consume alcohol regularly or have liver disease

Acetaminophen is hepatically metabolized, and liver disease or chronic alcohol use greatly increases the risk of liver toxicity even at therapeutic doses.

Question 52: What is a key component of effective debriefing after a rescue operation?

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

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.
