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

Question 1: Which symptom suggests a possible spinal injury?

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

Correct answer: Numbness or tingling in the extremities.

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

Question 2: A patient was bitten on the hand by a spider several hours ago. The bite site is red with two small fang marks, but the patient's primary complaint is severe, cramping abdominal pain and muscle rigidity. These systemic symptoms are most characteristic of a bite from which spider?

Brown Recluse
Hobo Spider
Wolf Spider
Black Widow (Correct answer)

Correct answer: Black Widow

Black widow venom is a potent neurotoxin that causes characteristic systemic symptoms, including severe muscle cramping (often in the abdomen and back), rigidity, nausea, and hypertension. Brown recluse bites are known for causing significant local tissue necrosis, but not the severe systemic muscle cramping described.

Question 3: When should a second dose of epinephrine be considered after the first injection for anaphylaxis?

After a mandatory 30-minute observation period
Only if the patient becomes unresponsive
If symptoms persist or return after 5–15 minutes (Correct answer)
Immediately after the first dose as standard protocol

Correct answer: If symptoms persist or return after 5–15 minutes

A second dose is appropriate if symptoms do not improve or recur within 5–15 minutes because anaphylaxis can be biphasic and epinephrine's duration is short.

Question 4: Epinephrine auto-injectors (EpiPens) are primarily used in wilderness medicine to treat which condition?

Anaphylaxis (Correct answer)
Severe asthma only
Cardiac arrest
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 5: Which over-the-counter medication provides pain relief, fever reduction, AND anti-inflammatory effects, making it especially useful for musculoskeletal injuries in the wilderness?

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

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

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

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

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

Question 7: What is the first priority when assessing a trauma patient in the wilderness?

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

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 8: A hiker takes a tumbling fall 20 feet down a steep, rocky embankment. They are awake, alert, and complaining of severe neck pain. They are also shivering and their hands feel cold. According to WFR spinal injury management protocols, which of the following is the MOST appropriate immediate action?

Encourage the patient to sit up slowly to see if the pain increases with movement.
Apply a cervical collar and immediately begin a litter evacuation.
Protect the spine from further trauma, treat for hypothermia, and then conduct a thorough assessment when the patient is stable. (Correct answer)
Perform a focused spine assessment to determine if the spine can be cleared.

Correct answer: Protect the spine from further trauma, treat for hypothermia, and then conduct a thorough assessment when the patient is stable.

The mechanism of injury (a 20-foot fall) is significant, warranting spinal precautions. However, the patient's shivering and cold hands indicate potential hypothermia, which is an immediate life threat. The correct approach is to first protect the spine from further movement (manual stabilization), then address the immediate life threat (hypothermia) by insulating and warming the patient. A reliable focused spine assessment cannot be performed on a patient whose judgment may be clouded by another condition like hypothermia.

Question 9: You are leading a six-person litter carry over steep and uneven terrain. To ensure the safety of the patient and the team, which of the following is the most critical leadership action?

Assigning the person at the front right position to be the team leader who calls out commands and upcoming hazards. (Correct answer)
Moving at the fastest possible safe pace to reduce exposure time.
Rotating carriers only when they explicitly state they are tired.
Enforcing silence so rescuers can concentrate on their footing.

Correct answer: Assigning the person at the front right position to be the team leader who calls out commands and upcoming hazards.

A designated leader, typically positioned at the patient's right shoulder or front right handle, is essential for coordinated and safe movement. This person has the best view of the terrain ahead and is responsible for communicating commands for lifting, lowering, and navigating obstacles, ensuring the entire team moves as a single unit. Silence prevents necessary communication, reactive rotations lead to exhaustion, and speed increases the risk of mistakes.

Question 10: A key contraindication to acetazolamide (Diamox) use is a known allergy to:

Latex
Penicillin
Sulfa drugs (Correct answer)
Iodine

Correct answer: Sulfa drugs

Acetazolamide is a sulfonamide derivative, and patients with sulfa drug allergies risk cross-reactivity and adverse reactions.

Question 11: What is the 'Rule of Threes' for survival priorities?

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

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

Equal chest rise with breathing.
Normal oxygen saturation levels.
Decreased breath sounds on the affected side.
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 13: 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.
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.
Drain the blister by puncturing it at its base with a sterilized needle, then apply a dressing. (Correct answer)

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 14: When should you initiate a rapid body survey?

Only for pediatric patients
When life-threatening conditions are suspected (Correct answer)
After completing a full patient history
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 15: When creating a "hypothermia wrap" or "burrito" for a patient in a litter, what is the correct layering sequence, starting from the layer closest to the patient and moving outwards?

Insulating pad, patient, sleeping bag (insulation), vapor barrier (tarp).
Patient, sleeping bag (insulation), vapor barrier (tarp), insulating pad.
Patient in dry layers, inside a sleeping bag (insulation), with an external vapor barrier (tarp) wrapped around everything. (Correct answer)
Patient, vapor barrier, sleeping bag (insulation), insulating pad, tarp.

Correct answer: Patient in dry layers, inside a sleeping bag (insulation), with an external vapor barrier (tarp) wrapped around everything.

The correct hypothermia wrap insulates the patient and protects them from the elements. The patient (ideally in dry clothes) provides the heat. The sleeping bag provides insulation to trap that heat. The external tarp acts as a vapor barrier to protect the insulation from wind and moisture (convective and evaporative heat loss). An insulating pad is placed underneath all of this to prevent conductive heat loss to the ground or litter.

Question 16: What is the safest way to signal for help in a remote area?

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

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

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

Correct answer: Diarrhea

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

Question 18: 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)
Rescue breaths are not performed in the wilderness due to the high risk of disease transmission.
The ratio of chest compressions to breaths is changed from 30:2 to 15:2 in the wilderness.
Chest compressions are performed at a slower rate (80/min) in the wilderness to conserve rescuer energy.

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

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

Question 19: Which of the following patient conditions presents the MOST urgent need for an immediate and rapid evacuation from a wilderness setting?

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

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 20: 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.
Provide 1 rescue breath every 6 seconds. (Correct answer)
Roll the patient into the recovery position and monitor the pulse.
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 21: 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?

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

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

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

Question 22: 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.
Checking the patient's airway, breathing, and circulation (ABCs).
Ensuring the safety of the rescuer and the group. (Correct answer)
Determining the mechanism of injury (MOI) for the patient.

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 23: Which plant is safest to consume in a survival situation if you're unsure of its edibility?

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

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 24: 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?

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

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 25: 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.
Controlling life-threatening external hemorrhage.
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 26: What is the most common sign of hypovolemic shock in trauma patients?

Hypertension (high blood pressure).
Pink, warm skin.
Rapid, weak pulse. (Correct answer)
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: What is the standard adult oral dose of diphenhydramine (Benadryl) for treating mild allergic reactions in the field?

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

Correct answer: 25–50 mg

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

Question 28: When managing a musculoskeletal injury like a sprained ankle in a remote wilderness setting, the acronym RICE (Rest, Ice, Compression, Elevation) is often recommended. What is the primary purpose of the 'Ice' component in the initial hours after the injury?

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

Correct answer: To reduce pain and control swelling.

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

Question 29: What does the 'A' stand for in the AVPU scale?

Ambulatory
Airway
Alert (Correct answer)
Arterial

Correct answer: Alert

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

Question 30: Which of the following best describes the correct Wilderness First Responder protocol for removing an embedded tick?

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

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

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

Correct answer: Assess the scene for safety

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

Question 32: Which of the following is a key symptom of a head injury requiring urgent evacuation?

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

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

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

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

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

Question 34: You are treating a severely hypothermic patient who goes into cardiac arrest. An AED is available. After delivering the first shock, the patient remains in a shockable rhythm. What is the most appropriate next action regarding the AED?

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

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

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

Question 35: 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.
Check for Circulation, Sensation, and Movement (CSM) distal to the injury. (Correct answer)
Administer pain medication before any further assessment.
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 36: What is the primary cause of altitude sickness?

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

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

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

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

Applying firm, direct pressure with a sterile dressing. (Correct answer)
Elevating the limb without pressure.
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 39: 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 40: How should you manage an open chest wound (sucking chest wound) in the field?

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

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 41: Which technique helps assess for potential internal bleeding?

Assessing skin turgor
Checking pupil response
Monitoring for tachycardia and hypotension (Correct answer)
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 42: What is the primary consideration when deciding to evacuate a wilderness patient?

Potential for condition to worsen in current environment (Correct answer)
Time of day
Patient's insurance coverage
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 43: 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.
Checking for a radial pulse and controlling major bleeding.
Assessing the level of consciousness using the AVPU scale.
Manually stabilizing the spine and checking the airway. (Correct answer)

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

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

Question 44: 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)
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.
Placing the arm in a sling without any additional rigid support.

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 45: 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 ice directly to the bite.
Apply a tight tourniquet above 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 46: How should you communicate with a panicked team member during a rescue?

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

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

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

Question 47: What is the primary treatment for anaphylaxis in a wilderness setting?

Immediate epinephrine injection (if available). (Correct answer)
Oral antihistamines alone.
Elevating the legs and drinking water.
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 48: What is the best way to ensure accountability during a multi-team rescue?

Assigning specific roles and using check-in systems. (Correct answer)
Assuming everyone knows what to do.
Letting volunteers choose their own tasks.
Avoiding role assignments to stay flexible.

Correct answer: Assigning specific roles and using check-in systems.

Clear role assignment ensures that every team member knows their specific responsibilities, preventing duplication of effort or critical tasks being overlooked. Implementing check-in systems provides regular updates on progress, challenges, and resource needs, enhancing coordination and accountability across multiple teams. This structured approach is essential for efficient and safe multi-team operations.

Question 49: 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 patient's pupils become fixed and dilated.
The rescuer is physically exhausted to the point of being unable to continue safely. (Correct answer)
A second rescuer has not arrived after 10 minutes.
The patient has been in cardiac arrest for only 15 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 50: When treating a patient for severe hypothermia in a wilderness setting, which action is most appropriate?

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

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

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

Question 51: How often should you reassess vital signs in a stable wilderness patient?

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

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

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