Struggling to breathe, an older adult client with end-stage chronic obstructive pulmonary disease (COPD) is admitted through the emergency department. The client is anxious and considering mechanical ventilation when the spouse interrupts the nurse and hands the nurse a copy of the client’s living will. Which action is most important for the nurse to take?

Choice A reason: Acetaminophen reduces pain but is secondary to preventing infection and bleeding with petrolatum dressings. Dressings are the immediate post-circumcision priority to protect the surgical site, per circumcision care and infection control protocols in neonatal nursing practice.

Choice B reason: Wrapping in blankets maintains warmth but does not address the surgical site’s immediate needs. Petrolatum dressings prevent infection and adhesion, critical post-circumcision. Warmth is secondary, per circumcision care and neonatal thermoregulation standards in nursing practice.

Choice C reason: Offering a glucose-dipped pacifier soothes but does not protect the circumcision site from infection or bleeding. Petrolatum dressings are the priority to ensure healing and comfort, per circumcision care and postoperative pain management standards in neonatal nursing practice.

Choice D reason: Applying petrolatum gauze dressings prevents infection, promotes healing, and reduces adhesion of the circumcision site to diapers. This is the priority intervention to protect the surgical wound, per evidence-based circumcision care and infection control protocols in neonatal nursing practice.

Choice A reason: Monitoring serum potassium is relevant, as lisinopril can cause hyperkalemia by reducing aldosterone, impairing potassium excretion. Skin turgor, however, assesses hydration, not ACE inhibitor effects. Blood pressure monitoring is more critical, as lisinopril lowers blood pressure via vasodilation, risking hypotension and falls, especially in elderly clients.

Choice B reason: Eosinophil count and constipation are unrelated to lisinopril’s effects. Elevated eosinophils may suggest allergies, but this is rare with ACE inhibitors. Constipation is not a common side effect. Lisinopril’s primary action is renin-angiotensin inhibition, making blood pressure and fall risk monitoring more urgent to prevent hypotensive complications.

Choice C reason: Lisinopril reduces angiotensin II, promoting vasodilation and lowering blood pressure. Monitoring blood pressure detects hypotension, which increases fall risk, particularly in older adults, due to dizziness or orthostatic changes. This directly assesses the drug’s cardiovascular effects, ensuring safety by preventing falls or syncope, making it the priority assessment.

Choice D reason: Heart rate and nausea are not primary lisinopril concerns. Tachycardia may occur secondary to hypotension, and nausea is rare. The drug’s main effect is blood pressure reduction via ACE inhibition, necessitating monitoring for hypotension and fall risk to ensure patient safety, as these are more immediate and significant pharmacological effects.
