A nurse who is mentoring a graduate nurse explains the correlation between severe blood loss and the effect on the client's mean arterial pressure (MAI The graduate nurse demonstrates correct understanding when he states which of the following:

It raises cardiac output and MAP.

It causes vasoconstriction and increased MAP.

There is no direct correlation to MAP.

Lower blood volume lowers MAP.

Answer and Explanation

The Correct Answer is D

A.   Severe blood loss actually decreases blood volume, which leads to decreased cardiac output and ultimately lower MAP.
B.   While it's true that the body initially responds to blood loss by vasoconstricting to maintain blood pressure, this compensatory mechanism can only last for so long. As blood loss continues, MAP will decrease.
C.   There is no direct correlation to MAP. MAP is directly influenced by cardiac output and systemic vascular resistance (SVR). Blood volume is a major determinant of both.
D.   A decrease in blood volume leads to decreased preload, which reduces cardiac output. This, in turn, lowers MAP.
