Describe a safe approach to post-exertional rehydration in rehab.

• A. Begin with plain water and monitor vitals only.
• B. Begin with fluids containing caffeine and sugar to restore energy.
• C. Begin with fluids containing electrolytes, monitor tolerance, and reassess vitals and hydration status before final clearance.
• D. Hydration can be skipped if the firefighter feels thirsty.

Answer: (C)

Post-exertional rehydration in rehab should start with fluids that contain electrolytes to replace what was lost in sweat. Electrolyte-containing drinks help restore sodium and other minerals, supporting normal fluid balance, nerve function, and muscle performance as the firefighter recovers. As fluids are given, closely monitor tolerance—watch for nausea, vomiting, abdominal cramping, or dizziness—and track vitals like heart rate, blood pressure, and, if possible, core temperature. Reassess hydration status by noting urine output and color, skin turgor, and overall signs of hydration before giving final clearance. This approach minimizes risks from overhydration with plain water and avoids the stimulatory effects of caffeine or excessive sugar, while recognizing that thirst alone is not a reliable guide after heavy exertion.
