When should the nurse suspect a need for further teaching regarding lisinopril?

The statement regarding skipping a dose once a week indicates a misunderstanding of the medication's regimen and its importance in managing a patient's condition. Lisinopril is an antihypertensive medication commonly used for treating high blood pressure and heart failure. Consistent daily dosing is crucial to maintain stable blood levels of the drug, ensuring effective management of the patient's condition. Skipping doses can lead to fluctuations in blood pressure control, potentially resulting in complications.

In contrast, the other statements reflect appropriate knowledge regarding the medication. Changing positions slowly can help prevent postural hypotension, a potential side effect of lisinopril. Taking the medication after breakfast aligns with a routine that can help patients remember to take it consistently. Recognizing the need to contact a physician for severe headaches is crucial as it could signal complications related to blood pressure management or side effects of the medication. Thus, understanding the importance of taking lisinopril daily without skipping doses is vital for effective treatment and patient safety.
