Which of the following is a symptom of heat exhaustion?
Dry skin
Paranoia
Moist skin
Hypervigilance
The Correct Answer is C
A. Dry skin:
This is more typical of heat stroke, where the body fails to regulate temperature and sweating stops.
B. Paranoia:
Paranoia is not a hallmark of heat exhaustion; it may be seen in severe hyperthermia or neurologic conditions.
C. Moist skin:
In heat exhaustion, the person continues to sweat as the body tries to cool down, resulting in cool, moist skin.
D. Hypervigilance:
Not a classic sign of heat exhaustion - this term refers to increased alertness, not typically associated with this condition.

Correct Answer is B
Explanation
A. Hypermetabolism:
While it increases the body’s energy demands, hypermetabolism itself does not directly compromise perfusion. It contributes to catabolism and worsening organ function over time, but perfusion deficits are due to vascular and circulatory issues.
B. Hypotension and micro-emboli formation:
Hypotension reduces overall blood flow to organs, and micro-emboli can block capillaries, both of which impair oxygen and nutrient delivery, leading to organ dysfunction/failure.
C. Hyperperfusion:
This is the opposite problem - increased blood flow. SIRS and MODS are marked by hypoperfusion.
D. Hyperglycemia:
Elevated glucose contributes to inflammation and poor outcomes, but it does not directly cause impaired perfusion like hypotension and emboli do.
Correct Answer is D
Explanation
A. Administering antibiotics:
Antibiotics are not used unless infection is suspected. Heat stroke is not an infectious condition.
B. Monitoring blood glucose levels:
While monitoring glucose may be part of general care, it is not the priority in heat stroke.
C. Providing hydration through oral fluids:
Oral fluids are contraindicated in unconscious or altered patients, which is often the case in heat stroke. IV fluids are preferred.
D. Rapid cooling of the body:
The primary concern in heat stroke is core temperature reduction to prevent organ damage. Ice packs, cooling blankets, and cold IV fluids are used.
