Which term describes heat stroke caused by environmental heat exposure?

• A. Non-Exertional Heat Stroke
• B. Drowning
• C. Barotrauma
• D. Altitude Sickness

Answer: (A)

Distinguishing heat stroke by cause: environmental heat exposure leads to non-exertional heat stroke. This form, sometimes called classic heat stroke, occurs when the ambient heat and humidity overwhelm the body's ability to dissipate heat, typically affecting vulnerable individuals during hot weather without strenuous activity. It presents with high core temperature and neurological impairment, and requires rapid cooling and supportive care.

The other terms don’t describe heat stroke from environmental heat exposure. Drowning involves inhalation of water and impaired oxygen delivery. Barotrauma is injury from pressure differences affecting air-filled spaces. Altitude sickness results from hypoxia at high elevations.
