Final answer:
The primary sign of heat stroke is hot, dry skin. Heatstroke is a serious condition when the body overheats and fails to cool down, which can lead to a core body temperature above 104°F and symptoms like confusion, nausea, and a lack of sweating. Option C.
Step-by-step explanation:
The primary sign of heat stroke on a worker is C) Hot, dry skin. Heatstroke is a severe condition that occurs when the body overheats and cannot cool down effectively, leading to potentially dangerous body temperatures.
It's characterized by a core body temperature above 104 degrees Fahrenheit (40 degrees Celsius), and symptoms include confusion, nausea, seizures, and a lack of sweating despite the heat.
This is counterintuitive because when someone is overheating, we might expect them to sweat excessively; however, in the case of heatstroke, the body's temperature regulation system fails, which can result in hot, dry skin.
Additionally, other signs and symptoms that may be associated with heatstroke are a fast heart rate, headache, and dizziness. It's important to recognize these symptoms early and provide immediate treatment to avoid serious complications, including potential damage to muscles and internal organs, or even death.
If a person is suspected of having a heatstroke, emergency medical services should be called immediately, and efforts should be made to cool the person down, such as moving them to a shaded area or applying cool water.
So Option C.
