A nurse is providing teaching to a client who has a new prescription for Lisinopril. Which of following statements by the client indicates an understanding of the teaching?

A. "I should report a persistent cough to my provider.": A dry, persistent cough is a common side effect of ACE inhibitors like Lisinopril. Reporting this symptom is important, as the provider may consider switching to another class of antihypertensives if it becomes bothersome. B. "I should take this medication as needed.": Lisinopril must be taken consistently every day to manage blood pressure effectively. Taking it only when symptoms are present is inappropriate and can lead to poor control and serious complications. C. "I should expect to have facial swelling when taking this medication.": Facial swelling (angioedema) is a serious and potentially life-threatening adverse effect, not something to expect or tolerate. If it occurs, the medication should be stopped and medical help sought immediately. D. "I should increase my intake of potassium-rich foods.": Lisinopril can increase serum potassium levels, leading to hyperkalemia. Clients should be advised to avoid excessive potassium intake and may need periodic lab monitoring.
