A nurse is providing teaching to a client who has a depressive disorder and a new prescription for phenelzine. Which of the following foods should the nurse instruct the client to avoid?

Choice A reason: Smoked salmon is high in tyramine, which phenelzine, an MAOI, prevents from being metabolized. This risks hypertensive crisis due to norepinephrine release, potentially causing stroke or cardiovascular complications. Avoiding tyramine-rich foods is critical for safety in clients on MAOI therapy. Choice B reason: Cottage cheese is low in tyramine, safe for phenelzine users. Unlike aged cheeses, fresh dairy poses minimal risk of hypertensive crisis, as it lacks significant tyramine content. MAOIs require avoiding high-tyramine foods, making cottage cheese an acceptable dietary choice for these clients. Choice C reason: Grapefruit affects CYP450 enzymes, interacting with some drugs, but is not contraindicated with phenelzine. It lacks significant tyramine, so it does not trigger hypertensive crises. Avoidance is unnecessary, as it does not impact MAOI metabolism or related cardiovascular risks. Choice D reason: Fresh apples are low in tyramine and safe for phenelzine users. MAOIs require avoiding tyramine-rich foods like aged meats, but fresh fruits do not cause hypertensive crises, as they lack amino acids interacting with MAOI metabolism, making them safe for consumption.
