What immediate action should be taken in response to severe heat exhaustion?

Moving the victim to a cooler place is the most critical immediate action in response to severe heat exhaustion. This condition occurs when the body loses an excessive amount of fluid and salt, typically due to prolonged exposure to high temperatures and heavy physical exertion.

By relocating the victim to a cooler environment, you help lower their body temperature, which is essential for preventing further deterioration of their condition. This action also allows the victim to recover in a place where they can regain fluids and electrolytes in a safe setting. Ensuring that the individual is in a shaded or air-conditioned area is vital to facilitate their recovery.

The other options do not provide the necessary support for managing severe heat exhaustion. Applying heat or allowing the victim to walk around could worsen their condition, as these actions do not address the critical need to cool down and rehydrate. Getting the victim outside may not be beneficial if the outdoor temperatures are also high, which could exacerbate the problem. The emphasis should be on providing immediate relief through cooling measures.
