Which set lists three common signs of heat illness to monitor in hot environments?

• A. Heat cramps, heat exhaustion, and heat stroke
• B. Dizziness, faintness, confusion
• C. Coughing, sneezing, rash
• D. Headache and nausea

Answer: (A)

Monitoring how the body responds in hot environments is about recognizing a progression of heat illness, from milder to life-threatening. The three common signs to monitor are heat cramps, heat exhaustion, and heat stroke. Heat cramps are painful muscle contractions caused by dehydration and electrolyte loss. Heat exhaustion follows with more systemic signs like weakness, dizziness, nausea, headache, sweating, and a rapid pulse, signaling that cooling and fluids are needed. Heat stroke is the most dangerous stage, with a rising core temperature and altered mental status, often accompanied by hot or dry skin, requiring immediate emergency care. This sequence guides appropriate action at each level and makes the trio the best set to watch for. The other options mix symptoms that aren’t recognized as a standard trio for monitoring heat illness.
