A nurse is teaching a client who is to undergo placement of a nontunneled percutaneous central venous access device. Which of the following statements should the nurse include in the teaching?

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.

Choice A reason: Occasional mild nausea is common in early pregnancy due to hormonal changes and does not typically require reporting unless severe or persistent. It is not a concerning finding at 14 weeks, so this is incorrect for urgent reporting.
Choice B reason: Mild ankle swelling in the evening can be normal due to fluid retention but is not urgent unless accompanied by other preeclampsia signs. It is less critical than bleeding, so this is incorrect for priority reporting.
Choice C reason: Vaginal bleeding at 14 weeks is abnormal and may indicate miscarriage, placental issues, or other complications, requiring immediate reporting to the provider for evaluation. This finding is critical at 14 weeks gestation, aligning with obstetric emergency protocols, making it the correct choice for teaching.
Choice D reason: Increased appetite is normal in pregnancy as nutritional needs rise and does not warrant urgent reporting. It reflects healthy adaptation rather than a complication, so this is incorrect for inclusion in teaching about concerning findings.
