A nurse is caring for a client who experienced severe head trauma. The client's partner asks the nurse why they are concerned about the mean arterial pressure (MAP). The nurse should explain that MAP determines which of the following?

Cerebral blood flow

The client's intake and output needs

Regulation of blood pressure

Resorption of cerebrospinal fluid

Answer and Explanation

The Correct Answer is A

A. Cerebral blood flow. MAP is crucial for maintaining adequate cerebral perfusion pressure, ensuring enough blood flow to the brain.

B. The client's intake and output needs. MAP does not directly influence intake and output needs; it is more directly related to blood flow and tissue perfusion.

C. Regulation of blood pressure. MAP is a measure of average blood pressure but not a regulator of it.

D. Resorption of cerebrospinal fluid. CSF resorption is not directly influenced by MAP; it’s regulated by intracranial pressure and other factors.

Correct Answer is B

Explanation

A. Warm extremities. PAD typically leads to cold extremities due to poor blood flow.

B. Intermittent claudication. Intermittent claudication, or muscle pain during exercise, is a classic symptom of PAD caused by limited blood supply to the muscles.

C. Darkened skin color near extremities. Darkened skin is more common in venous insufficiency, not PAD. PAD can cause pale or bluish skin.

D. Edema. Edema is typically associated with venous insufficiency, not PAD.

A. Obtain a pair of slipper socks for the client. B. Increase the client's oral fluid intake. C. Rub the client's feet briskly for several minutes. D. Place a moist heating pad under the client's feet.

Correct Answer is A

Explanation

A. Obtain a pair of slipper socks for the client. Slipper socks can provide warmth without applying direct heat, which is safer for clients with impaired circulation.

B. Increase the client's oral fluid intake. Increasing fluids does not directly address cold feet and may be contraindicated depending on the client’s condition.

C. Rub the client's feet briskly for several minutes. Rubbing can damage skin and tissue in clients with poor circulation and should be avoided.

D. Place a moist heating pad under the client's feet. Heating pads can cause burns and further impair circulation in clients with vascular issues.
