The situation described involves a person who has collapsed on a hot summer day and has an elevated body temperature of 106 degrees Fahrenheit. This high temperature suggests the person may be suffering from a heat-related illness, most likely heat stroke. Heat stroke is characterized by:
- Hot skin: The person's skin feels hot to the touch due to elevated body temperature.
- Disorientation: Confusion or altered mental status is common during heat stroke.
- Hypotension: Low blood pressure may occur due to dehydration and heat stress.
However, sweating is a thermoregulatory mechanism the body uses to cool down. In classic heat stroke, the body's cooling mechanisms fail, and absence of sweating (anhidrosis) is a typical symptom, especially in a hot and dry environment. Thus, among the given options, sweating is the least likely symptom to be seen in heat stroke. The correct answer is:
Sweating
