A nurse is caring for a client who has been taking lisinopril for several months. The nurse should plan to check which of the following laboratory values to monitor for adverse effects of the medication?

Choice A rationale Monitoring calcium levels is not typically necessary for patients taking lisinopril, as it does not significantly affect calcium levels. Choice B rationale Sodium levels are not commonly affected by lisinopril, so routine monitoring is not required. Choice C rationale Lisinopril can cause hyperkalemia (high potassium levels), so monitoring potassium levels is crucial to prevent complications. Choice D rationale Magnesium levels are not significantly impacted by lisinopril, so routine monitoring is not necessary.
