Which statement accurately contrasts heat exhaustion and heat stroke?

• A. Heat exhaustion—profuse sweating; heat stroke—cold or pale skin; treat with warm blankets.
• B. Heat exhaustion—sweating, cool moist skin, dizziness; heat stroke—no sweating, confusion, hot skin; treat with cooling, fluids if available, oxygen, and rapid transport.
• C. Heat exhaustion—no sweating; heat stroke—excessive sweating; treat with rest.
• D. Heat exhaustion—rapid transport only; heat stroke—immediate antibiotics.

Answer: (B)

Differentiating heat exhaustion from heat stroke hinges on how the body's cooling mechanism is functioning and how that guides urgent care. In heat exhaustion, the body is still producing sweat, and the skin is typically cool and moist. People often feel dizzy, weak, or nauseated, but their mental status remains normal. The best care is to move them to a cooler environment, have them rest, give fluids if they can drink, and use cooling measures as needed while monitoring for worsening signs. In heat stroke, the thermoregulation system has failed. Sweating often stops, and the skin becomes hot, red, and dry or may feel very moist early on. Confusion, agitation, or even loss of consciousness is common. This is a medical emergency, requiring aggressive rapid cooling (such as immersion in cool water or other effective cooling methods), supplemental oxygen if needed, and rapid transport to a hospital. Fluids may be given if the patient can safely take them, typically via IV when trained personnel are available. So the correctly describing statement captures the key contrasts—sweating with cool moist skin and dizziness in heat exhaustion versus no sweating with altered mental status and hot skin in heat stroke—and aligns the treatment with rapid cooling, fluids if possible, oxygen, and swift transport for heat stroke.
