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 A

Explanation

A. "Cardiac rehabilitation cannot undo the damage to your heart, but it can help you get back to your previous level of activity safely." This response is therapeutic and educative, helping the client understand that while damage cannot be reversed, rehabilitation supports safe recovery and improved quality of life.

B. "Your doctor is the expert here, and I'm sure he would only recommend what is best for you." This response does not address the client’s concerns and lacks supportive or educational value.

C. "You are probably right and I agree with you, but I still think you should go." This dismissive response fails to provide support, education, or empathy.

D. "It's not unusual to feel that way at first, but once you learn the routine, you'll be fine." Although this statement offers some support, it lacks the educational element needed to address the client’s concerns about the purpose of rehabilitation.

A. "I am constipated." B. "My vision seems yellow C. "My tongue is red and beefy." D. "I am gaining weight."

Correct Answer is B

Explanation

A. "I am constipated." Constipation is not a common indicator of digoxin toxicity; it may be more related to diet or other medications.

B. "My vision seems yellow." Yellow or blurred vision, also called xanthopsia, is a classic sign of digoxin toxicity and should be reported immediately.

C. "My tongue is red and beefy." A red and beefy tongue may indicate vitamin B12 deficiency, not digoxin toxicity.

D. "I am gaining weight." Weight gain is usually a sign of fluid retention or worsening heart failure, not specifically digoxin toxicity.
