The nurse is providing discharge instructions to a client who is prescribed lisinopril, an ACE inhibitor. Which statement by the client demonstrates proper understanding of the discharge instructions?

Choice A reason: Lisinopril can cause hyperkalemia due to reduced potassium excretion. Salt substitutes often contain potassium chloride, which can exacerbate this risk. Reviewing ingredients prevents excessive potassium intake, which could lead to dangerous cardiac arrhythmias, demonstrating proper understanding of dietary precautions. Choice B reason: Missing a dose of lisinopril if feeling unwell is dangerous, as it may worsen hypertension or heart failure. Consistent dosing is critical to maintain therapeutic effects, and this statement indicates a misunderstanding requiring further teaching on medication adherence. Choice C reason: Dizziness upon standing (orthostatic hypotension) is a side effect of lisinopril due to vasodilation and reduced blood pressure. Accepting this as normal without reporting it could delay intervention for excessive hypotension, indicating a need for further education. Choice D reason: Unlimited intake of high-potassium foods like potatoes, bananas, and oranges can lead to hyperkalemia in clients taking lisinopril, risking cardiac arrhythmias. This statement reflects a lack of understanding of dietary potassium restrictions, necessitating further teaching on safe dietary practices.
