Question

select the correct answer. what is the difference between heat exhaustion and heat stroke?
a. heat exhaustion is a decrease in blood volume, while heat stroke is an increase in blood volume.

b. heat exhaustion is an increase in blood volume, while heat stroke is a decrease in blood volume.

c. heat exhaustion involves extreme sweating, while heat stroke involves a lack of sweating.

d. heat exhaustion involves a lack of sweating, while heat stroke involves extreme sweating.

Explanation:

To determine the correct answer, we analyze the characteristics of heat exhaustion and heat stroke:

• Heat exhaustion typically involves extreme sweating as the body tries to cool down.
• Heat stroke occurs when the body's cooling mechanism (sweating) fails, leading to a lack of sweating, along with a rapid rise in body temperature.

Now let's evaluate the options:

• Option A: Incorrect. Blood volume changes are not the primary distinction between heat exhaustion and heat stroke.
• Option B: Incorrect. Similar to A, blood volume is not the key differentiator.
• Option C: Correct. Matches the known characteristics of heat exhaustion (extreme sweating) and heat stroke (lack of sweating).
• Option D: Incorrect. It reverses the sweating patterns of heat exhaustion and heat stroke.

Answer:

C. Heat exhaustion involves extreme sweating, while heat stroke involves a lack of sweating.
