Final answer:
Yogurt is an appropriate food choice for a client with a new prescription for phenelzine, as it is generally low in tyramine and does not pose a risk for hypertensive crisis when consumed in moderation.
Step-by-step explanation:
The nurse should include yogurt as an appropriate food choice for a client with a new prescription for phenelzine. Phenelzine is a monoamine oxidase inhibitor (MAOI) used to treat certain types of depression, and it requires dietary restrictions to avoid a hypertensive crisis. Foods that are high in tyramine such as aged cheeses, fermented meats (like pepperoni), smoked or processed meats (like smoked salmon), and certain fruits and vegetables (like avocados) should be avoided because they can interact with MAOIs and lead to dangerously high blood pressure. Yogurt, especially those that are not aged or cultured for a long time, is generally considered safe in moderation.
