A) The amount of oxygen available to tissues throughout the body
B) The volume of the venous system relative to the volume of the arterial system
C) The size of the client's heart muscle
D) The resistance that the client's heart must overcome when pumping blood
D
Feedback:
Blood pressure is representative of the amount of resistance that the heart must overcome in order to pump blood; increased BP equates with increased resistance, or afterload. Blood pressure is not necessarily indicative of oxygen supply, the relative volumes of the venous and arterial systems or the size of the heart.
