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)
