NREMT Emergency Medical Technician (EMT) Cognitive ExamTraumaEasy
A 19-year-old female was found unresponsive after spending several hours hiking in extreme heat. Her skin is hot, red, and dry. She has a rapid, weak pulse. This presentation is MOST indicative of:
- AHeat exhaustion
- BHeat stroke
- CDehydration
- DHeat cramps
Show answer & explanationAnswer & explanation
Correct answer: B. Heat stroke
The critical indicators for heat stroke are altered mental status (unresponsive) and hot, dry skin (indicating a failure of the body's thermoregulatory system). Heat exhaustion typically involves profuse sweating and a more preserved mental status.
Why the other options are wrong
- A. Heat exhaustion typically presents with profuse sweating, pale skin, weakness, and dizziness, but usually the patient is responsive.
- C. Dehydration is a contributing factor but not the specific diagnosis for this severe presentation; heat stroke is the medical emergency.
- D. Heat cramps involve muscle spasms and are not associated with unresponsiveness or hot, dry skin.
Heat Stroke Management
A life-threatening condition caused by the body's inability to regulate its temperature, characterized by a core temperature >104°F (40°C), altered mental status, and hot, dry or moist skin.
- Medical emergency, rapid cooling is essential.
- Remove from hot environment, remove clothing.
- Cool with water, ice packs (neck, armpits, groin).
- Monitor ABCs and prepare for seizures/vomiting.
