An 80-year-old resident of an assisted living facility is proud of the fact that he was an elite athlete during his younger years
Despite his concerted efforts to remain physically active and maintain his stamina, he is lamenting his loss of exercise tolerance in recent years. How can his nurse best respond to these concerns? A) "It's inevitable that your heart increases in size as you age, and this is associated with a loss of cardiac efficiency.".
B) "It's normal for your heart to contract less strongly as you age, and this makes you somewhat less able to exercise vigorously.".
C) "As you age, it's common for your heart rate becomes less regular and this often results in fatigue.".
D) "The normal increase in blood pressure that accompanies aging leaves you with less cardiac reserve capacity than when you were young.".
B
Feedback:
Cardiac contractility decreases as a part of normal aging. An increase in heart size, irregular heart rate, and increased blood pressure would be considered pathological conditions regardless of age.
