Answer to Question 1

ANS: C
Furosemide is a diuretic, used to rid the body of excess fluid, and it is excess fluid that leads to increased preload. Digoxin is often used in heart failure for its positive inotropic actions. Dopamine increases contractility. Metoprolol is a beta blocker, and its major effect is blocking sympathetic nervous system activity.

Answer to Question 2

ANS: C
The pulmonary artery is the only artery in the body to carry deoxygenated blood. It is an artery because it carries blood away from the heart.
