After administering lisinopril it is most important for the nurse to monitor which assessment finding?

Rationale: A. Blood pressure and risk for falls: Lisinopril is an ACE inhibitor that lowers blood pressure by blocking the renin-angiotensin-aldosterone system. The most important assessment is monitoring for hypotension, which increases fall risk, especially in older adults or when standing suddenly. B. Serum potassium and skin turgor: Lisinopril can cause hyperkalemia due to reduced aldosterone, so potassium should be monitored. However, this is a secondary concern compared with the immediate risk of hypotension and falls after administration. C. Eosinophil count and constipation: These findings are not commonly associated with lisinopril use. Eosinophil changes and constipation do not reflect the drug’s primary effects or the most urgent risks to the client’s safety. D. Heart rate and reports of nausea: Lisinopril does not typically alter heart rate significantly, and nausea is not a primary concern with this medication. The main risk immediately following administration remains hypotension, which can compromise perfusion and safety.
