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

Question 1: How should you manage an open chest wound (sucking chest wound) in the field?

Leave it open to air.
Apply a standard bandage without sealing.
Cover it tightly with plastic and tape on three sides. (Correct answer)
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 2: What is the first priority when assessing a trauma patient in the wilderness?

Assessing the ABCs (Airway, Breathing, Circulation). (Correct answer)
Elevating the legs to prevent shock.
Asking about allergies.
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 3: What is the primary treatment for anaphylaxis in a wilderness setting?

Waiting to see if symptoms worsen.
Elevating the legs and drinking water.
Oral antihistamines alone.
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 4: A patient develops hives, wheezing, and hypotension shortly after receiving a medication in the field. What is the most appropriate immediate intervention?

Administer epinephrine IM immediately (Correct answer)
Administer diphenhydramine orally and monitor closely
Discontinue the medication and observe for 30 minutes
Give oral fluids and place the patient in a recovery position

Correct answer: Administer epinephrine IM immediately

Hives, wheezing, and hypotension together constitute anaphylaxis, which requires immediate IM epinephrine as the definitive life-saving first-line treatment.

Question 5: What does the 'A' stand for in the AVPU scale?

Airway
Ambulatory
Arterial
Alert (Correct answer)

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 6: What is the primary cause of altitude sickness?

Dehydration alone.
Physical exhaustion.
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 7: 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?

Vital Signs (Correct answer)
Chief Complaint
Mechanism of Injury
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 8: You are treating a patient for anaphylaxis and have administered a dose of epinephrine via an auto-injector. Their symptoms initially improve, but 15 minutes later, their breathing becomes difficult again and the hives return. What is the correct course of action?

Immediately begin CPR.
Administer a second dose of epinephrine. (Correct answer)
Assume the first dose was ineffective and begin rapid evacuation only.
Administer a large dose of an oral antihistamine.

Correct answer: Administer a second dose of epinephrine.

Anaphylaxis can have a biphasic or rebound reaction, where symptoms recur after initially improving. The treatment for this rebound reaction is the same as the initial treatment: administer another dose of epinephrine. WFR protocols allow for repeating epinephrine doses every 5-15 minutes if symptoms persist or return. While antihistamines are part of the treatment, epinephrine is the primary life-saving medication. CPR is only indicated if the patient is pulseless and not breathing.

Question 9: Which action is most effective to prevent frostbite in subzero conditions?

Drinking alcohol to stay warm.
Rubbing skin vigorously to increase blood flow.
Using hand warmers and dry gloves. (Correct answer)
Wearing damp socks to acclimate to cold.

Correct answer: Using hand warmers and dry gloves.

To prevent frostbite in subzero conditions, the most effective action is to keep extremities warm and dry. Using hand warmers and wearing dry, insulated gloves provides direct heat and prevents heat loss through conduction and evaporation. Maintaining warmth and dryness is crucial as wetness and cold are primary contributors to frostbite.

Question 10: 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.
Exertional Hyponatremia; restrict fluids and give salty foods. (Correct answer)
Heat Stroke; immediately and aggressively cool the patient.
Severe Dehydration; give more water and electrolytes 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 11: When should a tourniquet be applied in wilderness trauma care?

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

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

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

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 13: A patient has a suspected closed fracture of their forearm. Which of the following describes the most appropriate improvised splinting technique?

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

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

Discussing lessons learned without judgment. (Correct answer)
Skipping the debrief to save time.
Assigning blame for mistakes.
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 15: What is the 'Rule of Threes' for survival priorities?

3 miles to safety, 3 people needed for rescue.
3 hours without sleep, 3 days without social contact.
3 days without water, 3 weeks without food.
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 16: When constructing an improvised litter with a tarp and two long, rigid poles, what is the most effective method for creating a secure patient platform?

Simply laying the tarp over the poles and placing the patient on top.
Folding one-third of the tarp over each pole towards the center, relying on the patient's weight and friction to secure it. (Correct answer)
Placing the poles inside sleeves made by folding and sewing the short ends of the tarp.
Lacing a rope through the tarp's grommets to the poles.

Correct answer: Folding one-third of the tarp over each pole towards the center, relying on the patient's weight and friction to secure it.

The standard and most secure method for a tarp and pole litter relies on tension and friction. By folding the tarp over the poles towards the center, the patient's weight tensions the fabric, creating a strong and secure platform. Using grommets will cause them to rip out, and simply laying the tarp on top provides no security.

Question 17: 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 18: Which symptom suggests a possible spinal injury?

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

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

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

Correct answer: Diarrhea

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

Question 20: Which medication is contraindicated in patients with suspected gastrointestinal bleeding or peptic ulcer disease?

Diphenhydramine
Ibuprofen (Correct answer)
Ondansetron
Acetaminophen

Correct answer: Ibuprofen

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

Question 21: A patient is stung by a wasp and develops hives on their chest and back, complains of a tight throat, and feels dizzy. After administering epinephrine, what is the most appropriate position for this patient while awaiting evacuation?

Sitting upright to make breathing easier.
Standing and walking around to improve circulation.
Lying flat with their legs elevated. (Correct answer)
In the recovery position on their left side.

Correct answer: Lying flat with their legs elevated.

The patient's dizziness indicates they are likely hypotensive (in shock) as a result of anaphylaxis. Lying flat with legs elevated (the shock position) uses gravity to help return blood to the body's core and brain. While sitting up can help with respiratory distress, the signs of shock take precedence. The patient should NEVER stand or walk.

Question 22: 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?

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

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 23: What is the first step in wilderness patient assessment?

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

Correct answer: Assess the scene for safety

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

Question 24: How should you treat a snakebite from an unidentified venomous snake in the field?

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

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

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

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 26: 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.
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)
Touch the tick with a recently extinguished hot match to shock it into releasing.

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 27: During your primary assessment of an unresponsive adult patient, you determine they are not breathing but have a definite carotid pulse. What is the correct intervention according to WFR life support protocols?

Begin cycles of 30 chest compressions and 2 breaths.
Roll the patient into the recovery position and monitor the pulse.
Provide 1 rescue breath every 6 seconds. (Correct answer)
Immediately apply an AED and follow the prompts.

Correct answer: Provide 1 rescue breath every 6 seconds.

The patient is in respiratory arrest, not cardiac arrest, because a pulse is present. The correct treatment is to provide rescue breaths to oxygenate the blood. The current guideline for an adult is to provide 1 breath every 6 seconds (10 breaths per minute). Starting chest compressions (CPR) is incorrect as the heart is still beating. An AED is only used for cardiac arrest and would not be effective.

Question 28: Which pulse point is most reliable for assessing circulation in cold environments?

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

Correct answer: Carotid pulse

Extremity pulses may be weak in hypothermic patients.

Question 29: Which of the following components is part of the secondary assessment in the Wilderness First Responder Patient Assessment System?

Controlling life-threatening external hemorrhage.
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)

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

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

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

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

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

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 34: 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.
Wait for professional rescuers to arrive.
Delegate tasks and maintain situational awareness. (Correct answer)

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 35: 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 36: Which technique helps assess for potential internal bleeding?

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

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

Applying a tourniquet immediately.
Applying firm, direct pressure with a sterile dressing. (Correct answer)
Elevating the limb without pressure.
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 38: Which of the following is a sign of tension pneumothorax?

Normal oxygen saturation levels.
Decreased breath sounds on the affected side.
Equal chest rise with breathing.
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 39: 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 developing wound infection. (Correct answer)
A normal healing process.
An allergic reaction to the bandage.

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

0.3 mg (Correct answer)
0.5 mg
0.1 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 41: What is the safest way to signal for help in a remote area?

Yelling continuously for help.
Creating three signals (e.g., three whistle blasts). (Correct answer)
Waving one arm overhead.
Building a single large fire.

Correct answer: Creating three signals (e.g., three whistle blasts).

The international distress signal is universally recognized as a series of three. Whether using three whistle blasts, three fires, three flashes of light, or three piles of rocks, this pattern clearly indicates a need for help and is more effective and less ambiguous than continuous or single signals. This standardized approach increases the likelihood of being understood and receiving assistance in a remote area.

Question 42: When should you initiate a rapid body survey?

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

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 43: 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.
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 44: According to Wilderness Medicine guidelines, which of the following is an accepted reason to discontinue CPR on a non-hypothermic patient in a remote setting?

The rescuer is physically exhausted to the point of being unable to continue safely. (Correct answer)
The patient's pupils become fixed and dilated.
The patient has been in cardiac arrest for only 15 minutes.
A second rescuer has not arrived after 10 minutes.

Correct answer: The rescuer is physically exhausted to the point of being unable to continue safely.

In a wilderness context, rescuer safety and viability are paramount. Continuing CPR to the point of complete exhaustion can endanger the rescuer and the rest of the group. Wilderness protocols specifically identify rescuer exhaustion as a valid reason to terminate resuscitation efforts, alongside other criteria like the return of spontaneous circulation, transfer of care, the scene becoming unsafe, or meeting specific criteria for non-viability after a set time (often 30 minutes).

Question 45: 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.
Check for Circulation, Sensation, and Movement (CSM) distal to the injury. (Correct answer)
Immediately splint the leg in the position found.
Ask the patient to stand and see if they can bear weight.

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

Anxiety and agitation
Diarrhea and cramping
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 47: 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?

Checking for a radial pulse and controlling major bleeding.
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.

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 48: 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)
A rapid, weak pulse
Heavy sweating

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

Pink, warm skin.
Rapid, weak pulse. (Correct answer)
Hypertension (high blood pressure).
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 50: What is the priority when treating a wilderness patient with severe bleeding?

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

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 51: A member of your group has a stable, isolated, and well-splinted ankle fracture. They are non-ambulatory. Your group is strong, the weather is good, and you are 4 miles from the trailhead on a clear trail. What is the most appropriate evacuation decision?

Insist the patient try to walk on the splinted ankle to speed up the evacuation.
Leave the patient with a small care team and send the majority of the group for help.
Construct an improvised litter and begin a slow, careful carry-out with the entire group. (Correct answer)
Send one person to run ahead for help while the rest of the group waits.

Correct answer: Construct an improvised litter and begin a slow, careful carry-out with the entire group.

Given a strong group, good weather, a clear trail, and a moderate distance, a self-evacuation via an improvised litter is a reasonable and efficient plan. This keeps the group together and initiates progress toward the trailhead without splitting the party or waiting for external resources, which may be unnecessary in this stable situation.

Question 52: Which of the following is a key symptom of a head injury requiring urgent evacuation?

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

Correct answer: Confusion or worsening headache.
