How does fatigue affect rehab decisions?

• A. Fatigue can mask symptoms and increase risk; rehab uses objective vitals and symptom checks to decide on rest and return-to-duty
• B. Fatigue has no effect
• C. Fatigue guarantees full recovery
• D. Fatigue reduces the need for hydration

Answer: (A)

Fatigue drives rehab decisions because it can hide how close a firefighter is to trouble and raise the risk of problems during recovery or when returning to duty. In rehab, staff rely on objective measures and symptoms rather than just how tired someone feels. If heart rate remains elevated after activity, blood pressure isn’t responding normally, core temperature is high, dehydration signs appear, or there are warning symptoms like dizziness or confusion, that signals more rest, hydration, cooling, or medical evaluation is needed before clearing to resume work. Fatigue doesn’t guarantee full recovery, and it doesn’t lessen the need for proper hydration; instead, it heightens the need to verify readiness with concrete vitals and symptom checks. The aim is to ensure the firefighter is physiologically and functionally ready to return to duty to prevent heat illness, cardiac strain, or impaired performance.
