NREMT Environmental Emergencies 1 — Questions and Answers
Question 1: A patient is found in a hot environment with altered mental status, hot dry skin, and a core temperature of 104°F (40°C). Which condition does this presentation most likely indicate?
- Heat exhaustion
- Heat stroke (Correct answer)
- Heat cramps
- Febrile seizure
Correct answer: Heat stroke
Heat stroke is characterized by altered mental status, hot skin, and a core temperature exceeding 104°F (40°C), making it a life-threatening emergency requiring immediate cooling.
Question 2: A hypothermic patient who was previously shivering has now stopped shivering. What does this indicate?
- The patient is beginning to rewarm spontaneously
- The patient's condition is improving due to rest
- The body can no longer generate compensatory heat, indicating worsening hypothermia (Correct answer)
- The patient has reached a normal core temperature
Correct answer: The body can no longer generate compensatory heat, indicating worsening hypothermia
Cessation of shivering in a hypothermic patient indicates the body's thermogenic mechanisms have been overwhelmed, signaling progression to severe hypothermia.
Question 3: You arrive to find a drowning victim who has been removed from the water. The patient is unresponsive and pulseless. What is your immediate priority?
- Apply a cervical spine immobilization device before moving
- Begin CPR immediately (Correct answer)
- Administer epinephrine 1:10,000 IV push
- Establish IV access and run a rapid fluid bolus
Correct answer: Begin CPR immediately
For a pulseless drowning victim, beginning CPR immediately is the highest priority, as prompt chest compressions and ventilations offer the best chance of survival.
Question 4: At a lightning strike mass casualty incident, which victim should receive priority care?
- A conscious patient complaining of severe chest pain
- An unconscious patient with no detectable breathing (Correct answer)
- A patient with superficial burns to the arms but normal vital signs
- A patient who is confused but walking and talking
Correct answer: An unconscious patient with no detectable breathing
Lightning strike incidents use reverse triage: pulseless and apneic victims are prioritized because they have the greatest chance of survival with immediate CPR, unlike other MCI scenarios.
Question 5: A patient presents with heavy sweating, pale moist skin, weakness, nausea, and a core temperature of 101°F (38.3°C) after working in the heat. Which condition does this most likely represent?
- Heat stroke
- Heat exhaustion (Correct answer)
- Malignant hyperthermia
- Exertional rhabdomyolysis
Correct answer: Heat exhaustion
Heat exhaustion presents with heavy sweating, pale moist skin, weakness, and nausea with a mildly elevated temperature, distinguishing it from heat stroke which features altered mental status and higher core temperatures.
Question 6: A patient has superficial frostbite (frostnip) to the fingers. Which field treatment is most appropriate?
- Vigorously rub the affected area to restore circulation
- Immerse the fingers in hot water at 120°F (49°C)
- Remove from the cold environment and rewarm gently using body heat (Correct answer)
- Leave the fingers exposed to open air for gradual rewarming
Correct answer: Remove from the cold environment and rewarm gently using body heat
Superficial frostbite should be managed by removing the patient from the cold and applying gentle body heat; vigorous rubbing causes tissue damage, and hot water immersion risks burns to insensate skin.
Question 7: After removing a heat stroke patient from the hot environment and excess clothing, what is the next most important cooling intervention?
- Administer oral fluids to rehydrate the patient
- Apply cool packs to the neck, armpits, and groin and fan the patient (Correct answer)
- Wait for ALS to arrive before initiating cooling measures
- Wrap the patient in a blanket to prevent shivering during transport
Correct answer: Apply cool packs to the neck, armpits, and groin and fan the patient
Applying cool packs to high-vascularity areas (neck, axillae, groin) and fanning promotes rapid cooling through conduction and evaporation, which is critical in heat stroke management.
