Answer to Question 1

B
Afterload reducers include the following:
captoprilprevents the conversion of angiotensin I to angiotensin II. It is a potent vasodilator. Afterload and cardiac output usually improve in 10 to 15 minutes.
enalapril (Vasotec)is a competitive ACE inhibitor and reduces angiotensin II levels.
nitroprusside (Nitropress)is a potent, direct smooth muscle-relaxing agent that primarily reduces afterload.
Norepinephrine (Levophed) may be used in the management of cardiogenic pulmonary edema; however, it is a positive inotropic agent, not an afterload reducer.

Answer to Question 2

E
Pulmonary embolism may cause noncardiogenic pulmonary edema. All of the other listed options may cause cardiogenic pulmonary edema.
