Answer to Question 1

2

Rationale 1: Phosphodiesterase inhibitors are used for only 23 days when other drugs have failed.
Rationale 2: Because of their toxicity, phosphodiesterase inhibitors are reserved for patients who have not responded to ACE inhibitors or cardiac glycosides, and they are generally used only for 23 days.
Rationale 3: Phosphodiesterase inhibitors are used for only 23 days when other drugs have failed.
Rationale 4: Phosphodiesterase inhibitors are used for only 23 days when other drugs have failed.

Global Rationale: Because of their toxicity, phosphodiesterase inhibitors are reserved for patients who have not responded to ACE inhibitors or cardiac glycosides, and they are generally used only for 23 days.

Answer to Question 2

2, 4

Rationale 1:Hypertension is incorrect because vasodilators cause orthostatic hypotension.
Rationale 2: Because of a high incidence of adverse effects, including reflex tachycardia and orthostatic hypotension, vasodilators play a minor role in the drug therapy of HF.
Rationale 3:Blurry vision is incorrect because this is a sign of digoxin (Lanoxin) toxicity.
Rationale 4: Because of a high incidence of adverse effects, including reflex tachycardia and orthostatic hypotension, vasodilators play a minor role in the drug therapy of HF.
Rationale 5:Hypokalemia is incorrect because this occurs with the administration of loop diuretics.

Global Rationale: Because of a high incidence of adverse effects, including reflex tachycardia and orthostatic hypotension, vasodilators play a minor role in the drug therapy of HF. Vasodilators are reserved for patients who cannot tolerate ACE inhibitors.
