During a hot summer day, construction workers are performing strenuous outdoor tasks. Which of the following is an early symptom of heat stroke, requiring immediate emergency medical attention?
- AHot, dry skin and confusion.
- BMuscle cramps and thirst.
- CDizziness and headache, but still sweating.
- DProfuse sweating with cool, moist skin.
Show answer & explanationAnswer & explanation
Correct answer: A. Hot, dry skin and confusion.
Heat stroke is a medical emergency characterized by a dangerously elevated body temperature and central nervous system dysfunction. Hot, dry skin (due to the body's inability to sweat effectively) and confusion are hallmark signs requiring immediate medical intervention.
Why the other options are wrong
- B. Muscle cramps and thirst are symptoms of heat cramps, a milder heat-related illness.
- C. Dizziness and headache with sweating are symptoms of heat exhaustion, not heat stroke.
- D. Profuse sweating with cool, moist skin is more indicative of heat exhaustion.
Heat Stroke Symptoms
Heat stroke is a severe, life-threatening heat-related illness characterized by a body temperature over 104°F (40°C), hot/dry skin, and central nervous system dysfunction like confusion or loss of consciousness.
- Medical emergency; call 911 immediately.
- Absence of sweating is a key indicator (though sometimes sweating can still occur).
- Confusion, slurred speech, seizures are common.
Memory trick: Cramps then Exhaustion, Stroke is the Worst Solution.
