Pharmacology Antihypertensives #3

Question

The nurse correctly explains to the client that which medication lowers the blood pressure by relaxing blood vessels?

Answers

  1. Losartan
    • Rationale:

      This answer is not correct because losartan is an angiotensin-receptor blocking agent (ARB) which lowers blood pressure by blocking the body’s natural renin-angiotensin aldosterone system (RAAS).

  2. Lovastatin
    • Rationale:

      This answer is not correct because lovastatin is a HMG-CoA reductase inhibitor that helps lower cholesterol levels. There are no blood pressure lowering properties in the drug.

  3. Captopril
    • Rationale:

      This answer is not correct because captopril is an Angiotensin-converting enzyme inhibitor (ACE-inhibitors), a common antihypertensive medication. It’s major side effects include a hacking, non-productive cough and angioedema.

  4. Nifedipine
    • Rationale:

      This answer is correct because nifedipine is a calcium channel blocker. These medications work to lower the blood pressure by relaxing blood vessels. Their uses also include use for peripheral spasms associated with Raynauds disease and during a myocardial infarction.
