Which statement is NOT typically associated with heat exhaustion?

• A. Fatigue
• B. Dizziness
• C. Sweating
• D. Severe confusion or loss of consciousness due to CNS dysfunction

Answer: (D)

Heat exhaustion comes from dehydration and impaired cooling during heat exposure. It typically shows fatigue, dizziness, and sweating as the body tries to shed heat, often with headache, nausea, or muscle cramps. Severe confusion or loss of consciousness indicates a breakdown of the brain’s ability to regulate temperature, which is not how heat exhaustion usually presents. That level of CNS dysfunction is a hallmark of heat stroke, where core temperature climbs very high and mental status can deteriorate rapidly, requiring urgent cooling and medical care. So the statement describing severe confusion or loss of consciousness is not typical of heat exhaustion.
