A nurse is caring for a client who has an abdominal aortic aneurysm and reports a feeling of heaviness in the chest while ambulating in the hall. Which of the following actions should the nurse take first?

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: Explaining the implications of a Do Not Resuscitate (DNR) status ensures the client understands that no CPR or intubation will occur if their condition deteriorates. This supports informed consent and autonomy, clarifying the scope of DNR to prevent misunderstandings. It respects the client’s decision-making capacity, ensuring their wishes align with end-of-life care preferences.
Choice B reason: Placing a “Do Not Resuscitate” sign outside the room breaches confidentiality under HIPAA, risking unauthorized disclosure of sensitive information. DNR status is communicated via medical records or wristbands. This action is inappropriate, as it does not contribute to implementing the client’s wishes and violates privacy standards, making it an incorrect response.
Choice C reason: Obtaining family consent is unnecessary for a competent client’s DNR request, as autonomy rests with the client. If decisionally capable, their wishes override family input. The nurse’s role is to support the client’s decision, not seek family approval, unless the client is incapacitated, which is not indicated, making this action inappropriate.
Choice D reason: Documenting the DNR request in the medical record ensures the care team follows the client’s wishes, preventing unwanted interventions. Accurate documentation communicates code status, supports legal and ethical standards, and ensures continuity of care. This is critical for aligning treatment with the client’s end-of-life preferences, making it a necessary action.
