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.

A. Methylprednisolone B. Dobutamine C. Furosemide D. Epinephrine

Correct Answer is D

Explanation

Methylprednisolone is a crucial medication in managing anaphylaxis but it takes longer to act compared to epinephrine and is not the immediate first-line treatment.
B. Dobutamine is a vasopressor used to treat heart failure. However, it's not indicated in the initial management of anaphylaxis.
C. Furosemide is a diuretic used for conditions like heart failure and edema. It has no role in treating anaphylaxis.
D. Epinephrine is the first-line treatment for anaphylactic shock. It rapidly reverses the life-threatening effects of anaphylaxis by constricting blood vessels, relaxing airway muscles, and stimulating the heart.
