Medical Surgical Labs Cardiac #2

Question

Which medications may be indicated for the client with a BNP of 428 pg/mL? Select all that apply.

Answers

  1. Oxygen
    • Rationale:

      This answer is correct because oxygen ensures sufficient ventilation for the client with CHF. The use of a nasal cannula creates adequate oxygen saturation. Care should be taken with the client who has CHF to avoid too much oxygen to prevent hyperinflation of the lungs.

  2. Lisinopril
    • Rationale:

      This answer is correct because lisinopril is an ACE inhibitor. ACE inhibitor medications are used for CHF to prevent reabsorption of salt and fluid. This stops the conversion of the renin-angiotensin-aldosterone system.

  3. Furosemide
    • Rationale:

      This answer is correct because furosemide is a diuretic. Diuretics are used to assist elimination of excess body fluid. This can prevent pulmonary edema.

  4. Amlodipine
    • Rationale:

      This answer is not correct because nifedipine is a calcium channel blocker. Calcium channel blockers induce activation of the renin-angiotensin-aldosterone system, which is already increased in clients with CHF.

  5. Digoxin
    • Rationale:

      This answer is correct because digoxin improves contractions of the heart muscles. This results in better cardiac output. Decreased cardiac output is a result of CHF.

Overview

A BNP over 100 pg/mL indicates congestive heart failure. Medications used to treat CHF are aimed at reducing the workload of the heart by improving the pumping of the heart and ridding excess fluid from the body.

Learning Outcomes

A BNP over 100 pg/mL indicates congestive heart failure.

Test Taking Tip

Having comprehension of the renin-angiotensin-aldosterone system will help the student answer this question. It increases blood volume by sodium and water reabsorption. This is not helpful for the client with congestive heart failure.
