Answer to Question 1

Ans:
C, D

Feedback:

Changes with aging contribute to the development of HF in older adults. First is reduced responsiveness to -adrenergic stimulation. Second is increased vascular stiffness that contributes to ventricular hypertrophy. Third, the heart itself becomes less compliant with age. Fourth relates to altered myocardial metabolism at the level of the mitochondria. Older adults usually develop aortic stenosis and mitral regurgitation. Kidney stones do not contribute to HF. Increase in diastolic pressure compromises LV filling leading to increases in pressures predisposing to HF. Arthritis is not associated with heart failure.

Answer to Question 2

Ans:
C

Feedback:

Thiazide diuretics increase the loss of potassium in urine. Because calcium is actively reabsorbed in the distal convoluted tubule, it is likely that her calcium level will go up, especially if she takes it for a long time.
