Which of the following is true about heat injury symptoms?

• A. Hot, dry skin is a sign of heat stroke
• B. Profuse sweating is common in heat stroke
• C. Heat stroke never involves altered mental status
• D. Heat stroke is always brief and mild

Answer: (A)

Heat stroke is a medical emergency where the body's cooling system fails and body temperature climbs rapidly. A key sign is hot, dry skin, because sweating can cease as the condition worsens, reflecting the body's inability to dissipate heat. This distinguishes heat stroke from heat exhaustion, where profuse sweating is more typical. Also, heat stroke often involves altered mental status, so saying it never affects mental function is incorrect. And it can be life-threatening, not something brief and mild. So hot, dry skin aligns with heat stroke symptoms, making it the best true statement.
