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.
