Which of the following is a symptom of heat exhaustion?

• A. Fatigue, nausea or vomiting, extreme thirst, cool pale moist skin, headache, weakness, dizziness
• B. Fever above 103 F with dry skin
• C. Severe chest pain and shortness of breath
• D. Rash and itching across the body

Answer: (A)

Heat exhaustion shows up after extended heat exposure with dehydration from sweating. The body’s response includes fatigue, nausea or vomiting, extreme thirst, and a combination of symptoms like headache, dizziness, weakness, and cool, pale, moist skin. This cool, moist skin sets it apart from heat stroke, where skin is hot and often dry and the fever is very high.

So the described signs—fatigue, nausea or vomiting, extreme thirst, cool pale moist skin, headache, weakness, and dizziness—fit heat exhaustion best. The other options describe fever with dry skin, chest pain with shortness of breath, or a rash, which align with different conditions rather than heat exhaustion. If symptoms worsen or include confusion, fainting, or seizures, seek urgent care.
