Answer to Question 1

Correct Answer: 3
Rationale 1: Both drugs can cause flushing as a consequence of peripheral vasodilation.
Rationale 2: Both drugs could cause dizziness because of peripheral vasodilation.
Rationale 3: Shortness of breath and dependent edema are symptoms and signs of possible heart failure. The cardiovascular effects of nifedipine (Procardia) are limited to vascular smooth muscle.
Rationale 4: Both drugs are associated with a risk of constipation because blocking calcium channels can decrease intestinal motility.
Global Rationale: Shortness of breath and dependent edema are symptoms and signs of possible heart failure. The cardiovascular effects of nifedipine (Procardia) are limited to vascular smooth muscle. Both drugs can cause flushing as a consequence of peripheral vasodilation; dizziness because of peripheral vasodilation; and are associated with a risk of constipation because blocking calcium channels can decrease intestinal motility.
