Which condition is defined by core temperature below 105°F, profuse sweating, pale skin, nausea, dizziness; treat by cooling and hydrating?

Which condition is defined by core temperature below 105°F, profuse sweating, pale skin, nausea, dizziness; treat by cooling and hydrating?

• A. Exertional Heat Exhaustion
• B. Exertional Heatstroke
• C. Heat Rash (Prickly Heat)
• D. Heat Syncope

Answer: (A)

Focusing on how the body responds to heat illness helps you tell these apart. In exertional heat exhaustion, the person is still sweating, the skin is cool and pale from vasodilation, and they may feel dizzy, nauseated, and fatigued. Core temperature is elevated but not severely high (in this scenario, under 105°F). Because sweating is present and fluids are lost, the key treatment is cooling the body and rehydrating promptly to restore volume and electrolytes. This fits the description: profuse sweating, pale moist skin, nausea, dizziness, and a core temperature below the threshold for heatstroke, all pointing to heat exhaustion rather than a more severe heat illness. In contrast, heatstroke involves a much higher core temperature (typically ≥104°F) with altered mental status and a hot, often dry skin, and heat rash is just a localized skin reaction, not a systemic illness. Heat syncope is mainly fainting from blood pooling with minimal systemic heat symptoms.
