Which symptom is characteristic of heat stroke?

• A. Cold, clammy skin
• B. Flushed, hot, moist skin
• C. Pale, cool skin
• D. Shivering with nausea

Answer: (B)

Heat stroke is a life-threatening heat illness where the body's cooling system fails and core temperature rises rapidly. A defining sign is skin that is very hot and flushed; sweating may still be present, so the skin can feel moist in some cases. This combination—flushed, hot skin with moisture from sweating—fits the described symptom. Other options reflect different conditions: cold, clammy or pale cool skin suggests shock or hypothermia, and shivering with nausea is more typical of cold exposure. Because heat stroke can cause rapid organ damage, act quickly to cool the person and seek emergency care.
