Correct Answer is B

Explanation

A. Cherries do not contain tyramine, which is the compound of concern for clients on MAOIs, so they can be included in the diet.
B. Cheddar cheese is high in tyramine, which can lead to hypertensive crises when consumed by clients taking MAOIs. Therefore, it should be eliminated from the diet.
C. Chicken is generally safe for clients on MAOIs as it does not contain significant amounts of tyramine.
D. Fresh fish is also safe to consume while on MAOIs as long as it is fresh and not aged, fermented, or spoiled, which could contain higher tyramine levels.

"Increase your potassium intake by eating more bananas and apricots." D. "The impaired taste associated with this medication usually goes away in 2 to 3 weeks."

Correct Answer is B

Explanation

A. Daily weight monitoring is not specifically indicated for doxazosin, and significant weight loss is typically not a primary concern with this medication.
B. Doxazosin can cause first-dose hypotension, leading to dizziness; thus, the client should be advised to lie down after the initial dose to minimize this risk.
C. Increasing potassium intake is not necessary with doxazosin; there are no direct interactions that would warrant dietary changes regarding potassium.
D. Impaired taste is not a commonly reported side effect of doxazosin; this statement is misleading and not relevant to the medication's profile.
