What is a vital component of first aid for heat stroke?

A vital component of first aid for heat stroke involves multiple interventions to effectively manage the condition. Each of the actions listed plays an important role.

First, removing the person from the heat is crucial because it helps to prevent further overheating and allows for a more effective cooling process. This action mitigates exposure to high temperatures that worsen heat stress.

Second, cooling the person with ice packs or cold compresses is integral to rapidly lowering the body temperature. This targeted approach can effectively reduce the core temperature, which is essential for survival.

Finally, immediate hydration with cold water addresses dehydration, which often accompanies heat-related illnesses. While hydration alone cannot treat heat stroke, it supports the body's recovery process.

Understanding that these actions work synergistically is why the correct answer encompasses all of them. Each component is necessary to ensure comprehensive first aid for someone experiencing heat stroke.
