Which is not a typical sign of heat stroke?

• A. Dry, red, hot skin
• B. Profuse sweating
• C. Altered mental status
• D. Core temperature 104 F or higher

Answer: (B)

Profuse sweating is not typical of heat stroke because heat stroke represents a breakdown of the body's ability to regulate temperature. When thermoregulation fails, the skin becomes hot and often dry, and the core temperature rises well above 104°F. Mental status changes such as confusion, agitation, or even coma are common due to CNS dysfunction. Sweating tends to stop or be markedly reduced in heat stroke, reflecting the failure of sweat production as part of the body’s cooling mechanism. Sweat presence is more characteristic of heat exhaustion, where the person is still sweating but shows signs like dizziness, weakness, and dehydration. So, profuse sweating does not fit the classic presentation of heat stroke, making it the not-typical sign in this scenario.
