Final answer:
If someone is suspected to have heat stroke, they should be cooled down gradually and given fluids to rehydrate.
Step-by-step explanation:
If you suspect that someone is experiencing heat stroke, you should have the individual gradually cool down, not stop immediately. It is important to lower their body temperature slowly to prevent shock. Having them sit in a cold bath can cause the body to cool too rapidly, which can also lead to shock. It is important to have them drink fluids to rehydrate, but avoid beverages that can induce vomiting, such as alcohol or caffeine. Having the individual lay with their face down is not an appropriate action for heat stroke.
