Which statement best describes the essential purpose of rehab in the field?

• A. Rest, rehydration, and recovery to prevent heat stress and fatigue.
• B. Only hydration is needed; rest is optional.
• C. Continuous activity to stay ahead of fatigue.
• D. Doff PPE immediately and take a break.

Answer: (C)

Rehab in the field is about giving responders a true recovery window after heavy work, so the body can cool, rehydrate, and regain energy before returning to duties. The essential purpose is rest, fluids, and cooling to prevent heat stress and fatigue, allowing safe, continued operation. After strenuous exertion, core temperature and heart rate remain elevated and fluids/electrolytes are depleted; rehab provides fluids, electrolytes, rest, and cooling, with medical assessment if needed, to restore readiness. Continuous activity would keep fatigue levels rising and increase the risk of heat illness, so staying in motion during rehab defeats its purpose. While taking a break and removing PPE can be part of rehab, the overall aim is the recovery process that enables safe return to work.
