Complete the following sentence by choosing from the list of options. Clients who are prescribed phenelzine should avoid foods containingdropdowndue to the risk for dropdown

• tyramine: Phenelzine is a monoamine oxidase inhibitor (MAOI) that inhibits the breakdown of tyramine, a naturally occurring amino acid found in aged cheeses, cured meats, and certain fermented foods. Excess tyramine can cause a sudden increase in norepinephrine levels, leading to dangerous cardiovascular effects. Clients must avoid high-tyramine foods to prevent serious complications associated with MAOIs. • Hypertensive crisis: Excessive tyramine intake in clients taking phenelzine can precipitate a hypertensive crisis, characterized by severe headache, elevated blood pressure, palpitations, chest pain, and potential stroke. This is a life-threatening reaction that occurs due to unopposed sympathetic stimulation. Dietary management and patient education are critical to prevent this adverse effect. • dairy: Routine dairy products do not contain significant tyramine unless they are aged or fermented. Consuming milk, fresh cheese, or yogurt does not generally trigger hypertensive crises in clients on phenelzine. Avoiding all dairy is unnecessary and unrelated to MAOI therapy. • tree nuts: Tree nuts are not a source of tyramine and do not interact with MAOIs to cause hypertensive crises. Regular consumption does not pose a cardiovascular risk for clients taking phenelzine. Dietary restriction of nuts is not required. • Anaphylaxis: Anaphylaxis is an acute allergic reaction and is unrelated to the tyramine–phenelzine interaction. MAOI-induced complications are primarily cardiovascular, not immunologic. Avoiding tyramine is aimed at preventing hypertensive emergencies rather than allergic reactions. • hyperkalemia: Hyperkalemia refers to elevated serum potassium and is not a known risk associated with phenelzine or tyramine-containing foods. Electrolyte disturbances are not the focus of dietary restrictions for MAOI therapy.
