Drinks that contain caffeine should be avoided for fluid replacement.

• A. Sugar
• B. Caffeine
• C. Salt
• D. Electrolytes

Answer: (B)

Caffeine is avoided for fluid replacement because it can act as a mild diuretic, increasing urine output and potentially reducing net fluid retention. In firefighter rehabilitation, the goal is to restore fluid volume and electrolyte balance quickly and predictably, using beverages that hydrate without promoting further fluid loss or causing adverse effects. Caffeinated drinks can hinder hydration by promoting water loss and, for some individuals, causing jitters or an upset stomach that complicates recovery. Other components like electrolytes help retain fluids and replace salts lost in sweat, and while sugar provides quick energy, it does not directly support hydration. Therefore, drinks containing caffeine should be avoided for fluid replacement.
