A nurse is assessing a client who has depression and takes phenelzine. The client reports eating pepperoni pizza while out on a pass during lunchtime. Which of the following assessments should the nurse perform?

A. Pupil response is not directly related to the risks associated with phenelzine or dietary restrictions. B. Bowel sounds are not directly relevant to the client's medication and dietary interaction risks. C. Oxygen saturation is not an immediate concern when assessing the effects of food interactions with phenelzine. D. Phenelzine, a monoamine oxidase inhibitor (MAOI), has significant dietary restrictions, especially related to foods high in tyramine, such as pepperoni. Consuming these foods can lead to hypertensive crisis, so monitoring blood pressure is essential.
