In heat stroke, sweating has ceased; which sign would indicate heat stroke?

• A. Profuse sweating
• B. Temperature 104 F
• C. Headache
• D. Hot, dry skin

Answer: (D)

When heat stroke develops, the body's cooling system fails and sweating often stops. The skin becomes hot and dry because evaporation can no longer occur, reflecting a breakdown of thermoregulation. Among the signs listed, hot, dry skin is the best indicator of heat stroke because it directly shows that sweating has ceased and the body can no longer dissipate heat. Profuse sweating would suggest heat exhaustion, not heat stroke; a temperature of 104°F can occur but isn’t specific enough on its own; a headache is nonspecific and can occur in many conditions.
