An older patient who enjoys good health is experiencing a decline in stamina despite being physically active over the years. The nurse recognizes which age-related change as likely affecting the patient's stamina?
A) Increased resting heart rate and blood pressure
B) Reduced heart contractility and a prolonged cardiac cycle
C) Stenosis of the aorta and decreased muscle tissue perfusion
D) Hypotension with consequent inadequate peripheral blood supply
B
Feedback:
An increased time for the systole–diastole cycle and a reduction in contractility are normal, age-related changes that affect activity tolerance. An increased heart rate and blood pressure would not be considered age-related changes while aortic stenosis would be characterized as pathological rather than normal. While many older adults experience hypotension, this is not considered a normal age-related change.
