Answer to Question 1

Correct Answer: 4
Rationale: Beta blockers and some calcium channel blockers reduce cardiac demand by lowering heart rate. Organic nitrates dilate vessels, and anticoagulants prevent blood clots from forming.

Answer to Question 2

Correct Answer: 3
Rationale: Nitroglycerin can dilate cerebral vessels, leading to headaches. Dysrhythmias, shortness of breath, and the development of a rash are not common.
