Correct: In the United States, the standard of care for pain assessment involves using a patient-reported numeric rating scale to establish a baseline. This subjective measurement is critical in wilderness medicine because it allows the provider to monitor trends over long durations. By reassessing pain after interventions like improvised splinting, wound care, or environmental adjustments, the Wilderness EMT can objectively evaluate whether the treatment plan is improving the patient’s condition or if further adjustments are necessary during a prolonged evacuation.

Incorrect: The strategy of relying solely on physiological markers like heart rate or blood pressure is flawed because these vitals are often influenced by dehydration, anxiety, or early stages of shock rather than pain alone. Choosing to assign a pain score based on the mechanism of injury or visible trauma ignores the subjective nature of pain and may lead to under-treating or over-treating the patient. Opting for the Wong-Baker FACES scale for all adults is generally inappropriate as it is specifically designed for pediatric populations or patients with language barriers, whereas the numeric scale is the standard for cognitively intact adults.

Takeaway: Pain is a subjective experience that must be quantified by the patient to evaluate the effectiveness of wilderness medical interventions over time.

Correct: For a stable medical patient in a wilderness setting, the secondary survey is designed to gather specific information through a focused physical exam of the affected area, a detailed SAMPLE history, and baseline vitals. This multi-faceted approach allows the provider to build a clinical picture that informs evacuation priority and field treatment when definitive care is hours or days away.

Incorrect: Performing a full head-to-toe exam from the scalp down for a localized medical complaint is often unnecessary and inefficient when no trauma is suspected. The strategy of waiting for a second set of vitals before starting any physical assessment unnecessarily delays the gathering of critical diagnostic information. Opting to skip the physical exam entirely and rely only on history ignores objective clinical signs like guarding or rigidity that are vital for assessing the severity of abdominal issues.

Takeaway: The secondary survey integrates focused physical findings, patient history, and vital signs to guide wilderness treatment and evacuation decisions.

Correct: In wilderness medicine, a reliable spinal assessment requires the absence of distracting injuries. A significant, painful injury like an angulated tibia fracture can mask the pain of a spinal injury, rendering the physical exam unreliable and necessitating spinal motion restriction.

Incorrect: Choosing to clear the spine based on the lack of tenderness ignores the clinical significance of the distracting injury which invalidates the assessment. The strategy of using a rigid backboard for an eight-hour evacuation is outdated and discouraged in wilderness settings due to the high risk of pressure sores and respiratory issues. Relying on a delayed assessment after oxygen administration does not address the underlying issue of the distracting injury and unnecessarily delays definitive care.

Takeaway: A distracting injury makes a wilderness spinal assessment unreliable, requiring the implementation of spinal motion restriction despite a lack of midline tenderness.

Correct: In a drowning or near-drowning scenario where a pulse is present but the patient is apneic, the primary goal is to reverse hypoxia. Rescue breathing is the critical intervention to prevent the patient from progressing to cardiac arrest. Wilderness protocols emphasize that most drowning victims suffer from respiratory arrest first; if a pulse is present, chest compressions are not indicated and the focus must remain on oxygenation.

Incorrect: Performing chest compressions is inappropriate when a palpable pulse is present, as it deviates from standard Basic Life Support and wilderness protocols for respiratory arrest. Prioritizing full spinal immobilization is generally discouraged in drowning unless there is a clear mechanism of injury, such as diving into shallow water, because it delays life-saving ventilations. The strategy of using abdominal thrusts to remove water from the lungs is an outdated and dangerous practice that increases the risk of vomiting and aspiration without improving clinical outcomes.

Takeaway: In drowning incidents with a palpable pulse, immediate rescue breathing to correct hypoxia is the highest clinical priority for a Wilderness EMT.

Correct: The patient is exhibiting classic signs of heat stroke, characterized by a high core temperature and altered mental status. In wilderness medicine protocols within the United States, heat stroke is a true medical emergency where the priority is to cool the patient immediately before or during transport. Aggressive cooling through cold water immersion or vigorous evaporative cooling (wetting the skin and fanning) is the most effective way to reduce the core temperature and prevent permanent neurological damage or death.

Incorrect: Relying on oral rehydration is contraindicated for patients with altered mental status due to the significant risk of airway compromise and aspiration. The strategy of prioritizing rapid evacuation over cooling is incorrect because the delay in lowering the core temperature during transport significantly increases the risk of multi-organ failure. Focusing only on localized cold packs to the axillae and groin is an outdated practice that is far less effective than whole-body cooling methods like immersion or aggressive evaporation.

Takeaway: In cases of suspected heat stroke, the clinical priority is to cool the patient aggressively and immediately before or during evacuation.

Correct: In lightning strike scenarios involving multiple victims, the principle of reverse triage is applied. Unlike standard triage where pulseless patients are categorized as expectant or deceased, lightning strike victims in cardiac or respiratory arrest are prioritized. This is because the initial cardiac arrest may resolve spontaneously, but the respiratory arrest often lasts longer, leading to a secondary, fatal cardiac arrest from hypoxia. Immediate ventilatory support or CPR can be life-saving for these specific patients who appear dead but are in a state of suspended animation.

Incorrect: Choosing to treat the disoriented hiker with skin markings first addresses a stable patient while neglecting one who is salvageable but currently in arrest. Focusing on the hiker with the femur fracture follows traditional triage logic for trauma but ignores the unique opportunity to reverse arrest in lightning victims. Attending to the hiker with ear trauma prioritizes a non-life-threatening injury over a critical, time-sensitive resuscitation effort that could prevent permanent death.

Takeaway: Reverse triage in lightning strikes prioritizes those in respiratory or cardiac arrest because they are often salvageable with immediate intervention.

Correct: In the compensated stage of shock, the body utilizes homeostatic mechanisms to maintain perfusion to vital organs. A narrowing pulse pressure occurs as the diastolic pressure rises due to systemic peripheral vasoconstriction, while the heart rate and respiratory rate increase to maintain cardiac output and oxygenation.

Incorrect: Focusing only on a significant drop in systolic blood pressure identifies decompensated shock, which is a late and often terminal sign rather than an early compensatory response. The strategy of looking for an increased pulse pressure and bradycardia describes Cushing’s Triad, which indicates increased intracranial pressure rather than hypovolemia. Relying on flushed or warm skin is clinically inaccurate for shock, as the body typically shunts blood away from the skin, leading to pale, cool, and clammy integumentary findings.

Takeaway: Identifying a narrowing pulse pressure and rising heart rate allows for early recognition of compensated shock before blood pressure collapses.

Correct: In the United States, the standard of care for pit viper envenomation involves minimizing movement to slow lymphatic spread and prioritizing rapid transport for antivenom. Keeping the limb neutral or slightly below heart level helps manage the balance between systemic spread and local tissue damage while ensuring the patient reaches definitive care as quickly as possible.

Incorrect: Relying on suction devices is ineffective for venom removal and often causes further soft tissue trauma at the bite site. The strategy of applying an arterial tourniquet is dangerous as it concentrates the necrotizing venom in the limb, leading to a significantly increased risk of amputation. Choosing to use ice or cold packs is contraindicated because it can worsen local tissue ischemia and necrosis without providing any clinical benefit in slowing venom absorption.

Takeaway: The primary wilderness treatment for pit viper bites is limb immobilization and rapid evacuation for definitive antivenom therapy.

Correct: Manually stabilizing the flail segment and then securing a bulky dressing or soft item like a jacket to the area helps minimize paradoxical movement and reduces the patient’s pain, which encourages more effective spontaneous respirations. This approach is standard in wilderness medicine to improve ventilatory mechanics without compromising the expansion of the uninjured side of the chest.

Correct: The Disability phase focuses on a rapid neurological assessment to identify life-threatening brain or spinal cord injuries using the AVPU scale and basic motor checks.

Incorrect: Simply conducting a detailed head-to-toe exam is part of the Secondary Survey and should not delay the identification of immediate neurological threats. The strategy of obtaining baseline vital signs occurs after the Primary Survey is complete to monitor trends over time. Focusing only on gathering a SAMPLE history is a component of the patient history and does not address the immediate physiological status of the patient.

Takeaway: The Disability assessment identifies immediate neurological life threats through level of consciousness and basic motor/sensory checks.

Correct: Geriatric patients often have a blunted physiological response to stress due to aging and common medications like beta-blockers, which can mask signs of shock or hypothermia. Their reduced subcutaneous fat and lower metabolic rate make them highly susceptible to environmental cold. In a wilderness setting, the WEMT must assume that even minor trauma could result in significant injury, such as a hip fracture, which the patient may underreport due to altered pain perception.

Incorrect: The strategy of relying on the patient’s self-reported pain levels or the absence of tachycardia is dangerous because age-related changes and medications often hide the severity of trauma. Focusing only on the shivering while ignoring potential diabetic complications fails to address the patient’s full medical history. Choosing to perform frequent vigorous physical exams can lead to unnecessary heat loss and patient discomfort in a remote environment. Opting for rapid movement without a thorough assessment for occult injuries risks exacerbating a potential fracture that the patient has not yet fully felt.

Takeaway: Geriatric wilderness patients require aggressive thermal protection and high suspicion for hidden injuries due to masked physiological responses and chronic medications.

Correct: The standard of care for tick removal in a wilderness setting involves mechanical extraction using fine-tipped tweezers. By grasping the tick at the mouthparts close to the skin and applying steady upward pressure, the provider minimizes the risk of breaking off the head or squeezing the body. This method is preferred because it reduces the likelihood of the tick regurgitating infectious pathogens, such as Borrelia burgdorferi, into the host’s bloodstream during the removal process.

Incorrect: The strategy of using petroleum jelly or nail polish to suffocate the parasite is ineffective and potentially dangerous as it may delay removal and increase the risk of infection. Choosing to twist the tick during extraction is contraindicated because it often results in the mouthparts breaking off and remaining lodged in the skin, which can lead to localized secondary infections. Opting for heat-based methods like matches or hot needles is highly discouraged by medical professionals because it frequently causes the tick to vomit into the wound, significantly increasing the transmission risk of various tick-borne illnesses.

Takeaway: Proper tick removal requires immediate mechanical extraction using steady upward traction with tweezers to minimize pathogen transmission and skin complications.

Correct: The patient is exhibiting classic signs of High Altitude Cerebral Edema (HACE), which is a life-threatening emergency characterized by ataxia (stumbling) and altered mental status. In a wilderness setting, the definitive treatment for HACE is immediate descent to a lower elevation to reduce intracranial pressure. Supplemental oxygen serves as a vital adjunct to improve oxygenation of brain tissues while the descent is underway.

Incorrect: The strategy of using analgesics and waiting for acclimatization is dangerous because HACE is a progressive condition that will not resolve without losing elevation. Focusing only on hydration assumes the symptoms are related to dehydration, which ignores the neurological red flags indicating brain swelling. Choosing to let the patient sleep is particularly hazardous, as mental status cannot be monitored and respiratory depression during sleep can exacerbate hypoxia. Relying on rest at the current altitude fails to address the underlying cause of the edema and significantly increases the risk of coma or death.

Takeaway: Ataxia and altered mental status at high altitude indicate HACE and require immediate descent to a lower elevation.

Correct: In a wilderness or pre-hospital setting, the hallmark of heat stroke is the presence of central nervous system dysfunction, such as confusion, agitation, or coma, combined with hyperthermia.

Incorrect: The strategy of looking for dry skin is often misleading as many patients with exertional heat stroke continue to sweat. Simply identifying a temperature of 101.5 degrees is insufficient because heat exhaustion frequently presents with moderate elevations in core temperature. Focusing on nausea and a fast heart rate is non-specific since these symptoms are common to both heat exhaustion and early heat stroke.

Takeaway: Altered mental status is the critical diagnostic feature that separates life-threatening heat stroke from heat exhaustion in wilderness medicine.

Correct: Removing wet clothing is the most critical step because water conducts heat away from the body significantly faster than air. In a wilderness setting, creating a hypothermia wrap with an insulated pad and a vapor barrier prevents further heat loss from conduction, convection, and evaporation, which is the standard of care for managing environmental cold stress.

Incorrect: The strategy of providing caffeinated beverages is contraindicated because caffeine acts as a diuretic and can worsen dehydration while exercise may be impossible for a patient with failing motor skills. Rubbing the extremities is dangerous as it can cause tissue damage and potentially trigger cardiac arrhythmias by shunting cold, acidotic blood from the limbs to the core. Relying on chemical heat packs placed directly on the skin is a mistake because vasoconstricted skin is highly susceptible to thermal burns and these packs do not provide the necessary total body insulation.

Takeaway: The primary goal in wilderness hypothermia management is to stop heat loss by removing wet layers and providing total body insulation.

Correct: In a wilderness context, a mid-shaft femur fracture requires traction to realign the bone, reduce muscle spasms, and manage internal bleeding. The improvised splint must provide consistent longitudinal tension to be effective. Because the patient will be in the splint for an extended period, the WEMT must be able to monitor the Circulatory, Sensory, and Motor (CSM) functions frequently to ensure the device is not causing neurovascular compromise or pressure injuries.

Incorrect: The strategy of wrapping the limb in a foam pad provides excellent stability for many fractures but fails to provide the necessary longitudinal traction required for a femur injury. Choosing to apply hitches directly to the skin is a dangerous practice that leads to rapid skin breakdown and pressure sores during a multi-day evacuation. Opting to anchor the splint against the pubic symphysis or the groin without significant padding can cause excruciating pain and risks compressing the femoral nerve or artery.

Takeaway: Improvised traction splints must maintain consistent tension and allow for regular neurovascular monitoring during extended wilderness evacuations.

Correct: In the wilderness setting, once the primary survey is complete, the secondary survey for a medical patient focuses on gathering objective data through vital signs and subjective data through a detailed history. The OPQRST mnemonic is the standard tool for evaluating the characteristics of pain or discomfort, which is essential for differentiating between various medical emergencies and determining the urgency of evacuation.

Incorrect: Choosing to perform a full head-to-toe trauma exam is inefficient when the patient presents with a clear medical complaint and no mechanism of injury. The strategy of initiating an immediate carry-out without completing the assessment risks unnecessary exertion for the team and may overlook critical diagnostic clues that could change the treatment plan. Relying solely on the SAMPLE history while delaying further evaluation or waiting for symptoms to resolve can lead to a dangerous delay in recognizing a deteriorating condition.

Takeaway: Effective wilderness medical assessment relies on combining a focused history using OPQRST with baseline vital signs to guide evacuation decisions.

Correct: In wilderness medicine, reducing specific dislocations such as the shoulder, patella, or digits is indicated when evacuation is delayed. Early reduction significantly reduces pain, simplifies the evacuation process, and protects the neurovascular bundle from prolonged compression. Techniques like the Stimson or Cunningham methods are preferred because they are gentle and rely on muscle relaxation rather than force.

Incorrect: The strategy of splinting in the position found is standard for urban EMS but is often inappropriate in remote settings where long-term transport would cause unnecessary suffering and potential vascular compromise. Choosing to wait 24 hours for spontaneous reduction is clinically unsound as muscle spasms typically worsen over time, making later reduction attempts much more difficult. Relying on high-force traction-countertraction is dangerous because it increases the risk of causing an iatrogenic fracture or damaging the axillary nerve, especially if an underlying fracture was already sustained during the fall.

Takeaway: In remote environments, early and gentle reduction of shoulder dislocations is prioritized to manage pain and prevent neurovascular complications.

Correct: In a wilderness setting, a diabetic patient presenting with altered mental status and sympathetic nervous system signs like diaphoresis and tachycardia should be treated for hypoglycemia. Administering oral glucose is the standard of care because the brain requires a constant supply of sugar, and the risks of giving sugar to a hyperglycemic patient are minimal compared to the immediate life-threat of untreated hypoglycemia.

Incorrect: The strategy of administering insulin is highly dangerous and outside the scope of EMT practice, as it could be fatal if the patient is already hypoglycemic. Focusing only on completing a full secondary survey before intervention unnecessarily delays life-saving treatment for a time-sensitive metabolic crisis. Choosing to elevate the legs and provide oxygen addresses potential shock or hypoxia but fails to treat the primary cause of the altered mental status, which is the lack of circulating glucose.

Takeaway: In wilderness settings, treat suspected diabetic emergencies as hypoglycemia by providing oral sugar if the patient can safely swallow.

Correct: In the Wilderness Patient Assessment System (PAS), the Primary Survey follows the ABCDE sequence. After addressing Airway, Breathing, and Circulation, the provider must evaluate Disability (Spine) and Exposure/Environment. Assessing for spinal tenderness and neurological deficits is critical given the mechanism of injury, and preventing heat loss is a priority in trauma management to avoid the lethal triad of trauma, especially in remote settings with dropping temperatures.

Incorrect: Focusing on a detailed head-to-toe exam for minor injuries is premature because the Primary Survey (ABCDE) must be completed before moving to the Secondary Survey. The strategy of obtaining vital signs and a SAMPLE history is also part of the Secondary Survey and should not delay the assessment of spinal stability or environmental protection. Choosing to evacuate the patient immediately without completing the assessment risks aggravating unidentified spinal injuries and fails to stabilize the patient for the duration of the transport.

Takeaway: The Primary Survey must include Disability and Exposure assessments to address spinal risks and environmental threats before starting the Secondary Survey.
