The nurse knows that an older adult client with a diagnosis of heart failure (HF) will most likely have compromised ability to perform activities of daily living upon discharge due to which of the following statements listed below?

A)
The client's musculature will be dependent on aerobic metabolism.
B)
The client's diagnosis will have contributed to cardiac muscle atrophy.
C)
Intramuscular acidification will cause the client to be more easily fatigued.
D)
The client will have experienced a shift toward the use of slow-twitch muscle fibers.

Question 2

A)
Conduction of heat from the air will be heating his skin surface and raising his core temperature.
B)
Blood volume at his skin surface will be increasing to dissipate heat.
C)
His autonomic nervous system will be stimulating him to sweat.
D)
Radiation from his skin surfaces will be dissipating heat into the environment.

Answer to Question 1

Ans:
C

Feedback:

HF patients experience increased fatigability due to intramuscular acidification. He will be more dependent on anaerobic metabolism and has likely experienced skeletal muscle atrophy and a shift toward increased fast-twitch muscle fibers.

Answer to Question 2

Ans:
B

Feedback:

In response to high temperatures, blood volume at the surface increases in order to dissipate heat. Heat exchange between his body and the air is radiation, not conduction, and the sympathetic, not autonomic, nervous system will be in control of the sweating process. Because the air temperature exceeds his body temperature, he will not be able to lose heat in this way.
