When a health care provider prescribes losartan, which nursing action is most appropriate?

• A. Monitor the client's blood pressure.
• B. Administer with meals.
• C. Check potassium levels daily.
• D. Assess for cough.

Answer: (A)

Losartan is an angiotensin II receptor blocker used to treat hypertension, and its primary effect is lowering blood pressure. Because of this, the most important nursing action after a provider prescribes it is to monitor the client's blood pressure to assess effectiveness and to detect any potential hypotension, especially after starting therapy or after a dose change. This safety check helps guide dose adjustments and when to hold or modify treatment. While monitoring potassium is important due to the risk of hyperkalemia with ARBs, and ARBs typically do not cause a cough (unlike ACE inhibitors), these are secondary considerations in the immediate safety assessment. Losartan can be taken with or without meals, so administration timing is not the critical safety focus. Thus, checking blood pressure promptly after initiating therapy best serves the patient’s safety and therapeutic goals.
