1. A nurse is assessing a patient who has a fever of 39°C.

The nurse knows that the patient's body is trying to lower

the temperature by:

a) increasing blood flow to the skin

b) shivering and increasing metabolic rate

c) decreasing heat production and heat loss

d) sweating and vasodilating the peripheral vessels

Answer: D. Sweating and vasodilating the peripheral

vessels are mechanisms of heat loss that help the body to

lower the temperature when it is too high. Increasing blood

flow to the skin, shivering and increasing metabolic rate,

and decreasing heat production and heat loss are

mechanisms of heat conservation that help the body to raise

the temperature when it is too low.

2. A nurse is caring for a patient who has hypothermia due

to exposure to cold weather. The nurse should monitor the

patient for which of the following complications?

a) cardiac dysrhythmias

b) hyperglycemia

c) respiratory alkalosis

d) increased cerebral blood flow

Answer: A. Cardiac dysrhythmias are a common

complication of hypothermia, as the cold temperature

affects the electrical activity of the heart. Hyperglycemia,

respiratory alkalosis, and increased cerebral blood flow are

not associated with hypothermia.

3. A nurse is teaching a group of nursing students about the
