Which pulse characteristic would be expected in a person experiencing heat stroke?

2. Rapid and weak

3. Rapid and strong

4. Normal and steady

The correct answer is: Rapid and strong

In cases of heat stroke, the body experiences a significant increase in core temperature due to prolonged exposure to high temperatures or excessive exercise in a hot environment. As the body's regulatory systems become overwhelmed, several physiological changes occur, including cardiovascular responses. A rapid and strong pulse is typically observed in individuals suffering from heat stroke. This is the body's attempt to maintain adequate blood flow and oxygen delivery to vital organs despite the stress of excessive heat. The heart rate increases to pump more blood, responding to the elevated metabolic demands and the potential for dehydration. Although the pulse may be rapid due to the body's efforts to cool itself and circulate blood effectively, it is likely to be strong initially as the body tries to compensate for the heat stress. This strong pulse reflects the body's heightened effort to manage its internal environment under extreme conditions.
