In a heat emergency, when is it appropriate to give water?

• A. If the patient does not feel dizzy
• B. If the patient does not feel nauseated
• C. If the patient is thirsty
• D. Never give water

Answer: (B)

In heat emergencies, offering water is appropriate only when the patient can protect their airway and swallow safely. The best cue is that the patient does not feel nauseated. If they’re not nauseated, you can provide small sips to help replace fluid losses from sweating. Thirst or dizziness alone aren’t reliable indicators for giving fluids, and giving water when the patient is nauseated increases the risk of vomiting and aspiration. If there’s vomiting, altered mental status, or inability to swallow, water should be withheld and the focus should be on safety, cooling, and transport.
