A nurse is collecting data from a client who is taking tranylcypromine and reports ingestion of tyramine-rich foods. The nurse should monitor the client for which of the following findings as an adverse effect of this medication?

A. Tinnitus is not typically associated with the ingestion of tyramine-rich foods while on tranylcypromine. B. Hyperglycemia is not a common adverse effect related to tyramine interaction with tranylcypromine. C. Hypertension is correct. Ingesting tyramine-rich foods (such as aged cheese, cured meats, and fermented foods) while taking tranylcypromine, a monoamine oxidase inhibitor (MAOI), can cause a hypertensive crisis. Tyramine is normally broken down by monoamine oxidase (MAO), and inhibiting this enzyme with tranylcypromine can lead to a dangerous increase in blood pressure. D. Hematuria is not a known adverse effect of tranylcypromine or the ingestion of tyramine-rich foods.
