What should be avoided when treating a heat stroke victim?

Restricting fluid intake in a heat stroke victim is inappropriate as it can worsen their condition. Heat stroke occurs when the body's temperature regulation fails, often leading to a core temperature that rises to dangerous levels. This can result in serious complications or even death. Providing fluids is essential because rehydration helps to lower body temperature and restore normal physiological functions.

In contrast, giving immediate emergency medical attention, moving the person to a shaded area, and pouring cold water over their body are all critical and effective responses to treat heat stroke. These actions help reduce the victim's body temperature and prevent further complications. Therefore, restricting fluid intake directly contradicts the necessary treatment for a heat stroke victim and underscores why it should be avoided.
