Answer to Question 1

ANS: C
Paroxysmal nocturnal dyspnea (shortness of breath generally occurring at night) occurs with heart failure. Lying down increases the volume of intrathoracic blood, and the weakened heart cannot accommodate the increased load. Classically, the person awakens after 2 hours of sleep, arises, and flings open a window with the perception of needing fresh air.

Answer to Question 2

ANS: B
With aging, an increase in systolic blood pressure occurs. No significant change in diastolic pressure and no change in the resting heart rate occur with aging. Cardiac output at rest is does not changed with aging.
