Final answer:
Tranylcypromine sulfate (Parnate), a monoamine oxidase inhibitor (MAOI), is used to treat major depression. The nurse should instruct the client to avoid consuming aged cheese due to its high tyramine content, which can cause a dangerous increase in blood pressure when combined with MAOIs.
Step-by-step explanation:
Tranylcypromine sulfate (Parnate) is a monoamine oxidase inhibitor (MAOI) used to treat major depression. When educating the client about their medication, the nurse should advise them to avoid consuming aged cheese. This is because aged cheese contains high levels of tyramine, which can cause a dangerous increase in blood pressure when combined with MAOIs. It is important for the client to adhere to a tyramine-free diet while taking tranylcypromine sulfate.
