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.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
