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

Question 1: In an unresponsive male trauma patient, which sign specifically suggests spinal cord injury?

Unequal pupils
Battle's sign
Priapism (Correct answer)
Raccoon eyes

Correct answer: Priapism

Priapism results from loss of sympathetic control and is a recognized sign of spinal cord injury.

Question 2: Which of the following is the most appropriate treatment for a large, intact, and tense friction blister on a hiker's heel that is causing significant pain and preventing them from walking effectively?

Remove the entire roof of the blister to allow the underlying skin to dry and harden.
Drain the blister by puncturing it at its base with a sterilized needle, then apply a dressing. (Correct answer)
Leave the blister intact and apply a thick donut-shaped moleskin pad around it to reduce pressure.
Apply a hot compress to the blister to encourage it to burst and drain on its own.

Correct answer: Drain the blister by puncturing it at its base with a sterilized needle, then apply a dressing.

For a large, painful, and tense blister that is likely to rupture anyway, the recommended WFR protocol is to carefully drain it. This should be done by sterilizing a needle and piercing the blister at its base to allow for drainage by gravity. The roof of the blister should be left intact to act as a natural, protective dressing. While a donut pad can help with a small, non-tense blister, it is less effective for a large, painful one. Removing the roof exposes raw skin, increasing pain and infection risk. Hot compresses are not recommended and could cause a burn.

Question 3: Thirty minutes after a fall, a hiker has a rapid pulse, rapid breathing, and pale, cool, clammy skin but is alert. What is the most likely problem?

Mild heat exhaustion
Compensated shock (Correct answer)
Hyperventilation from anxiety only
Increased intracranial pressure

Correct answer: Compensated shock

Elevated heart and respiratory rates with pale, cool skin in an alert trauma patient suggest compensated shock.

Question 4: Which factor makes hypoglycemia more likely in a diabetic on a wilderness trip?

Staying at low altitude
Increased exercise combined with usual insulin dosing and inadequate food intake (Correct answer)
Eating extra carbohydrates
Reduced physical activity

Correct answer: Increased exercise combined with usual insulin dosing and inadequate food intake

Strenuous exertion increases glucose use, so unchanged insulin with insufficient calories easily causes low blood sugar.

Question 5: What is the best way to remove an attached tick?

Burn it with a match
Cover it with petroleum jelly and wait
Twist it rapidly while squeezing the body
Grasp it close to the skin with fine tweezers and pull steadily (Correct answer)

Correct answer: Grasp it close to the skin with fine tweezers and pull steadily

Steady traction with tweezers close to the skin removes the tick without squeezing infected fluids into the wound.

Question 6: A rescued near-drowning patient is now breathing and alert. Why should they still be evacuated for evaluation?

Legal requirements only
To treat hypothermia only
Respiratory problems can develop hours later (Correct answer)
Water in the stomach must be pumped

Correct answer: Respiratory problems can develop hours later

Lung injury from aspiration can worsen over hours, so monitoring is needed.

Question 7: Bruising behind the ear several hours after a fall most strongly suggests which injury?

Mandible fracture
Basilar skull fracture (Correct answer)
Ruptured eardrum only
Cervical spine strain

Correct answer: Basilar skull fracture

Battle's sign (mastoid bruising) is a classic delayed sign of basilar skull fracture.

Question 8: What is the best way to communicate with a frightened, conscious patient during care?

Avoid talking so they stay calm
Tell them everything will definitely be fine
Explain what you are doing, use their name, and be honest without causing alarm (Correct answer)
Discuss their prognosis with others within earshot

Correct answer: Explain what you are doing, use their name, and be honest without causing alarm

Calm, honest explanations and using the patient's name build trust and reduce anxiety.

Question 9: What most reliably distinguishes heat stroke from heat exhaustion in the field?

Altered mental status (Correct answer)
Presence of sweating
Heart rate
Skin color

Correct answer: Altered mental status

Central nervous system dysfunction defines heat stroke; patients may still be sweating.

Question 10: Immediately after a frightening accident, a bystander is shaky, tearful, and briefly disoriented but uninjured. This is best described as:

An acute stress reaction (Correct answer)
Post-traumatic stress disorder
Conversion paralysis
Schizophrenia

Correct answer: An acute stress reaction

Short-lived emotional and physical symptoms right after a traumatic event characterize an acute stress reaction.

Question 11: Heat loss from lying directly on cold, snowy ground occurs mainly by which mechanism?

Convection
Radiation
Evaporation
Conduction (Correct answer)

Correct answer: Conduction

Conduction is direct heat transfer to a colder surface in contact with the body.

Question 12: Why is recording the time of each set of vital signs important in wilderness documentation?

It replaces the need for an assessment section
It is only required for billing purposes
It establishes trends that guide treatment and evacuation decisions (Correct answer)
It satisfies Good Samaritan law requirements

Correct answer: It establishes trends that guide treatment and evacuation decisions

Timed vitals reveal whether a patient is improving or deteriorating over the often long wilderness care period.

Question 13: For a severely hypothermic patient, how long should you check for a pulse before concluding none is present?

10 seconds
5 seconds
3 minutes
Up to 60 seconds (Correct answer)

Correct answer: Up to 60 seconds

Pulses may be very slow and faint in hypothermia, so a check of up to 60 seconds is recommended.

Question 14: You are treating a patient with a painful, swollen, and deformed ankle after they slipped on a wet log. Before and after applying a splint, you assess CSM. Which of these checks evaluates the 'Sensation' component?

Lightly touching a toe and asking the patient, 'Can you feel this?' (Correct answer)
Noting if the skin of the foot is pale and cool to the touch.
Asking the patient to wiggle their toes.
Feeling for a pedal pulse on the top of the foot.

Correct answer: Lightly touching a toe and asking the patient, 'Can you feel this?'

Assessing 'Sensation' involves checking for normal nerve function. This is typically done by lightly touching the skin distal to the injury and asking the patient if they can feel it, or if it feels the same as the uninjured side. Feeling for a pulse checks 'Circulation,' asking them to wiggle toes checks 'Motion,' and skin color/temperature is also part of the 'Circulation' assessment.

Question 15: Which pattern of vital signs is a late sign of rising intracranial pressure?

Fast pulse, normal blood pressure, regular breathing
Slow pulse, low blood pressure, slow regular breathing
Slow pulse, rising blood pressure, irregular respirations (Correct answer)
Fast pulse, low blood pressure, rapid shallow breathing

Correct answer: Slow pulse, rising blood pressure, irregular respirations

Bradycardia, hypertension, and irregular breathing (Cushing's triad) indicate late-stage increased ICP.

Question 16: Which water treatment method is effective against bacteria, viruses, and protozoa but does NOT remove chemical contaminants?

Charcoal filtering alone
Boiling (Correct answer)
Sediment settling
Cloth straining

Correct answer: Boiling

Boiling kills all pathogens but does not remove chemicals or toxins.

Question 17: Several days after a cold, a trekker has facial pain that gets worse when bending forward, plus thick discolored nasal discharge. Most likely condition?

Migraine
Nasal fracture
Dental abscess
Sinusitis (Correct answer)

Correct answer: Sinusitis

Facial pressure that worsens when bending forward, with purulent discharge, is typical of sinusitis.

Question 18: A known diabetic is confused but awake and able to swallow. What is the best initial treatment?

Withhold food until evacuation
Give oral sugar such as glucose gel or juice (Correct answer)
Give their insulin injection
Have them exercise to raise blood sugar

Correct answer: Give oral sugar such as glucose gel or juice

A conscious hypoglycemic patient who can protect their airway should receive oral sugar.

Question 19: Before and after reducing a dislocated shoulder in the field, what must you always assess?

Blood glucose
Circulation, sensation, and motion distal to the injury (Correct answer)
Core temperature
Pupil response

Correct answer: Circulation, sensation, and motion distal to the injury

CSM checks confirm nerve and blood vessel function before and after any reduction.

Question 20: Which technique helps assess for potential internal bleeding?

Assessing skin turgor
Monitoring for tachycardia and hypotension (Correct answer)
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 21: Where are 'anticipated problems' recorded in a wilderness SOAP note?

History
Subjective
Assessment (Correct answer)
Objective

Correct answer: Assessment

The Assessment includes the problem list and problems you anticipate may develop.

Question 22: A woman has lower abdominal pain, fever, foul-smelling vaginal discharge, and pain when walking. What should you suspect?

Pelvic inflammatory disease that needs evacuation for antibiotics (Correct answer)
Normal menstrual cramps
Kidney stone
Muscle strain from hiking

Correct answer: Pelvic inflammatory disease that needs evacuation for antibiotics

Fever, abnormal discharge, and pelvic pain suggest pelvic inflammatory disease, which needs medical treatment.

Question 23: During a generalized seizure, what should you do?

Hold the limbs firmly to stop movement
Place a stick between the teeth
Pour water on the face to wake them
Protect the head and clear hazards, then place in recovery position afterward (Correct answer)

Correct answer: Protect the head and clear hazards, then place in recovery position afterward

Seizure care focuses on preventing injury, never restraining or inserting objects into the mouth.

Question 24: What is the first priority when assessing a trauma patient in the wilderness?

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

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

Pink, warm skin.
Slow, deep breathing.
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 26: A fractured tooth shows a pink or bleeding spot in the center of the break. What does this mean?

The pulp is exposed; cover it and get dental care soon (Correct answer)
It is a normal gum injury
The tooth is avulsed
Only enamel is involved, so no urgency

Correct answer: The pulp is exposed; cover it and get dental care soon

Visible pink tissue or bleeding means the pulp is exposed, which is painful and prone to infection.

Question 27: Why is it important to record multiple sets of vital signs over time?

Single readings are legally inadmissible
Trends reveal whether the patient is improving or deteriorating (Correct answer)
It keeps the patient calm
Vital signs are always inaccurate the first time

Correct answer: Trends reveal whether the patient is improving or deteriorating

Trends over time are more useful than any single reading for guiding care and evacuation.

Question 28: Which statement best describes the purpose of the 'Plan' section of a SOAP note?

To list the patient's medications
To describe treatment, evacuation, and monitoring for each problem (Correct answer)
To record the mechanism of injury
To document vital sign trends

Correct answer: To describe treatment, evacuation, and monitoring for each problem

The Plan outlines what you will do about each problem, including evacuation decisions.

Question 29: Using the adult rule of nines, a burn covering one entire arm represents about what percentage of body surface area?

9% (Correct answer)
1%
18%
4.5%

Correct answer: 9%

Each adult arm equals roughly 9% of total body surface area.

Question 30: When is activating a personal locator beacon (PLB) most appropriate?

To request a resupply of food
When there is a life-threatening emergency and no other means to summon help (Correct answer)
When the group is running late but everyone is fine
When someone has a minor injury and could walk out

Correct answer: When there is a life-threatening emergency and no other means to summon help

PLBs alert search and rescue and should be reserved for true emergencies when other communication is unavailable.

Question 31: While checking circulation in the primary survey you find bright red blood soaking a patient's pant leg. What should you do?

Splint the leg before addressing bleeding
Record a full set of vital signs first
Finish the primary survey, then return to the leg
Control the bleeding immediately with direct pressure (Correct answer)

Correct answer: Control the bleeding immediately with direct pressure

Severe bleeding is a life threat and is controlled as soon as it is found during the primary survey.

Question 32: A patient has a segment of ribs moving inward on inhalation after a fall. What is appropriate field management?

Wrap the chest tightly with circumferential tape
Have the patient lie flat on their back and stay still
Stabilize the segment with a bulky pad and monitor breathing (Correct answer)
Push the segment outward during exhalation

Correct answer: Stabilize the segment with a bulky pad and monitor breathing

Flail chest is managed by gently stabilizing the segment and supporting ventilation, not tight wrapping that restricts breathing.

Question 33: An unresponsive hiker is found alone on a trail. How is consent obtained for treatment?

Implied consent applies (Correct answer)
A park ranger must authorize care
Written consent must be obtained once the patient wakes
Treatment cannot begin until a family member is contacted

Correct answer: Implied consent applies

Implied consent assumes an unresponsive patient would want lifesaving care.

Question 34: Which of the following statements best describes a primary difference in the approach to Cardiopulmonary Resuscitation (CPR) in a wilderness versus an urban setting?

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.
Rescue breaths are not performed in the wilderness due to the high risk of disease transmission.
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 35: A competent, alert adult with a suspected ankle fracture refuses your care. What is the appropriate action?

Restrain them until help arrives
Respect the refusal, explain the risks, and document it (Correct answer)
Leave the scene immediately
Treat them anyway because it is an emergency

Correct answer: Respect the refusal, explain the risks, and document it

A competent adult may refuse care; inform them of the risks, keep offering help, and document the refusal.

Question 36: A hiker has an isolated, splinted forearm fracture with intact distal CSM and can walk. What is the most appropriate evacuation choice?

Request an immediate helicopter evacuation
Carry out in a litter with a team of 12
Walk out under their own power with a companion (Correct answer)
Stay in place until a ground rescue team arrives

Correct answer: Walk out under their own power with a companion

A stable patient who can walk safely should self-evacuate, because it avoids the time, risk and manpower of a carry-out.

Question 37: You arrive at a climbing crag where a climber has fallen. What is your FIRST priority?

Assess the scene for hazards such as rockfall (Correct answer)
Ask bystanders what happened
Take a full set of vital signs
Check the patient's airway

Correct answer: Assess the scene for hazards such as rockfall

The scene size-up, beginning with rescuer safety, always comes before any patient contact.

Question 38: A runner on a hot day is confused, combative, and has hot skin. What is the priority treatment?

Rest in the shade for an hour
Give salt tablets
Give oral fluids and observe
Rapid cooling, ideally by cold-water immersion (Correct answer)

Correct answer: Rapid cooling, ideally by cold-water immersion

Heat stroke is a true emergency requiring immediate aggressive cooling.

Question 39: Which of the following patient conditions presents the MOST urgent need for an immediate and rapid evacuation from a wilderness setting?

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.
A closed, angulated tibia fracture with good distal circulation, sensation, and motion (CSM).

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 40: Which finding is most characteristic of HAPE?

Shortness of breath at rest and a wet cough (Correct answer)
Severe headache only
Ataxia
Facial swelling

Correct answer: Shortness of breath at rest and a wet cough

HAPE causes fluid in the lungs with dyspnea at rest, cough, and decreased exercise tolerance.

Question 41: Which combination best suggests tension pneumothorax?

Worsening respiratory distress, absent breath sounds on one side, distended neck veins (Correct answer)
Hyperventilation with tingling fingers
Fever, productive cough, and crackles
Wheezing that improves with an inhaler

Correct answer: Worsening respiratory distress, absent breath sounds on one side, distended neck veins

Tension pneumothorax shows progressive distress, unilateral absent breath sounds, and JVD.

Question 42: 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 43: Informed consent requires the WFR to explain which of the following?

Only the WFR's certification level
The legal history of the trip company
The patient's insurance coverage
The nature of the treatment, its risks, benefits, and alternatives (Correct answer)

Correct answer: The nature of the treatment, its risks, benefits, and alternatives

Informed consent means the patient understands the proposed care, its risks and benefits, and alternative options.

Question 44: Which finding after a head injury should prompt evacuation rather than monitoring in the field?

Persistent vomiting and worsening headache (Correct answer)
Mild bump at the impact site
Momentary dizziness with normal exam afterward
Brief headache that resolves within an hour

Correct answer: Persistent vomiting and worsening headache

Persistent vomiting and a worsening headache are red flags for rising intracranial pressure.

Question 45: During the scene size-up, which of these is NOT a standard component?

Using body substance isolation
Determining the mechanism of injury
Identifying the number of patients
Measuring the patient's respiratory rate (Correct answer)

Correct answer: Measuring the patient's respiratory rate

Respiratory rate is a vital sign obtained during the secondary survey, not the scene size-up.

Question 46: On a multi-day evacuation, which consideration is most important for rescuers?

Discarding extra gear to move faster
Leaving the patient alone at night
Food, water, shelter and rest for both patient and rescuers (Correct answer)
Moving as fast as possible without breaks

Correct answer: Food, water, shelter and rest for both patient and rescuers

Long evacuations need planned logistics for everyone, or rescuers become casualties.

Question 47: Which pit viper envenomation sign is most typical?

Immediate paralysis with no local pain
A painless bite with a target rash
Muscle rigidity in the abdomen only
Progressive local swelling and pain spreading from the bite (Correct answer)

Correct answer: Progressive local swelling and pain spreading from the bite

North American pit viper bites typically cause progressive local swelling, pain, and possible bruising.

Question 48: A patient has abdominal organs protruding through a wound. What is correct care?

Leave uncovered to allow airflow
Gently push organs back inside
Cover with dry gauze pressed firmly
Cover with a moist, sterile dressing and keep warm (Correct answer)

Correct answer: Cover with a moist, sterile dressing and keep warm

Eviscerations are covered with moist sterile dressings and never replaced into the abdomen.

Question 49: During a focused spine assessment, which finding PREVENTS you from ruling out spinal injury?

Patient is alert and oriented x4
Normal sensation in all four extremities
A painful, angulated femur fracture (Correct answer)
No midline spinal tenderness

Correct answer: A painful, angulated femur fracture

A distracting injury can mask spinal pain, so the spine cannot be cleared.

Question 50: Which item is generally the best choice to fill voids between a patient and the litter sides?

Ice packs to reduce swelling
Rocks or hard water bottles
Nothing, so the patient can move
Rolled clothing, foam pads or soft gear (Correct answer)

Correct answer: Rolled clothing, foam pads or soft gear

Soft padding in gaps stops the patient from shifting and prevents pressure points.

Question 51: For a healthy adult, what is the generally accepted maximum total dose of acetaminophen in 24 hours?

8 grams
1 gram
10 grams
4 grams (Correct answer)

Correct answer: 4 grams

Going above about 4 g/day (less with alcohol use or liver disease) raises the risk of liver damage.

Question 52: In the backcountry, which fluid is acceptable for wound irrigation?

Only sterile normal saline
Full-strength hydrogen peroxide
Undiluted stream water
Water that is safe to drink (Correct answer)

Correct answer: Water that is safe to drink

Studies show potable or disinfected drinking water is as effective as sterile saline for irrigation.
