Massachusetts OEMS Protocols Basic Life Support (BLS) Practice Exam

Oral rehydration is appropriate for mild heat-related illness when the patient can swallow and protect the airway. If the patient is conscious, has an intact gag reflex, and is not vomiting, giving oral fluids helps replace lost water and electrolytes during heat cramps or heat exhaustion. The gag reflex matters because it reduces the risk of aspiration; if these protections aren’t present, oral fluids should not be given.

While cooling measures are essential, hydration can be done concurrently when the patient meets these safe-for-swallow criteria. The other options are too restrictive or require IV access even when it isn’t necessary for mild dehydration.
