Ans: C
Feedback: The CVP is a measurement of the pressure in the vena cava or right atrium. Since the pressure in the vena cava, right atrium, and right ventricle are equal at the end of diastole, the CVP also reflects the filling pressure of the right ventricle (preload). The normal CVP is 2 to 6 mm Hg.
