Final answer:
The most indicative signs of exertional heat stroke are a body core temperature greater than 104°F (40°C), hot and either wet or dry skin, disorientation, and irritable or irrational behavior.
Step-by-step explanation:
Exertional heat stroke is a serious condition characterized by several distinct signs and symptoms. The most indicative signs and symptoms of exertional heat stroke in the scenario presented would include:
- Body core temperature greater than 104 degrees Fahrenheit (40 degrees Celsius)
- Hot and wet or dry skin
- Disoriented
- Irritable/Irrational behavior
These symptoms are reflective of the critical temperature range for metabolic reactions in the body, with proteins and enzymes beginning to lose their structure and function at elevated temperatures, leading to potential organ system failures.
