Pharmacology Antibiotics #14

Question

The nurse is providing education to a patient with a history of rheumatic heart disease. Information includes risk factors for bacterial endocarditis. The nurse asks through teach-back if the patient knows the importance of taking which of the following drugs prior to scheduled invasive procedures?

Answers

  1. Amoxicillin
    • Rationale:

      This answer is correct because to help reduce the risk of bacterial endocarditis, the patient should take prophylactic antibiotics, such as amoxicillin, prior to any invasive procedure, including dental procedures. Rheumatic heart disease patients are at a higher risk of having bacterial (infective) endocarditis and should be taught to take these measures to prevent a very serious infection in the heart.

  2. Solumedrol
    • Rationale:

      This answer is not correct because solumedrol is a glucocorticoid that treats inflammation. It is not the correct medication to help prevent endocarditis in patients with rheumatic heart disease. Antibiotics, such as amoxicillin, is the best choice for prevention of endocarditis.

  3. Warfarin
    • Rationale:

      This answer is not correct because warfarin is an anticoagulant used for prevention of clots.
      It is not the correct medication to help prevent endocarditis in patients with rheumatic heart disease. Antibiotics, such as amoxicillin, is the best choice for prevention of endocarditis.

  4. Metoprolol
    • Rationale:

      This answer is not correct because metoprolol is a beta blocker used to decrease blood pressure and heart rate in many patients. It is not the correct medication to help prevent endocarditis in patients with rheumatic heart disease. Antibiotics, such as amoxicillin, is the best choice for prevention of endocarditis.

Overview

Bacterial endocarditis can occur in patients with rheumatic heart disease. The patients should take prophylactic antibiotics, such as amoxicillin, prior to any invasive procedures.

Explanation

Learning Outcomes

Bacterial endocarditis is a condition which can occur if a person has rheumatic heart disease. To help reduce this risk, the patient should take prophylactic antibiotics, such as amoxicillin, prior to any invasive procedure, including dental procedures. Rheumatic heart disease occurs as the result of the patient not adequately treating strep throat or scarlet fever. Rheumatic heart disease patients are at a higher risk of having bacterial (infective) endocarditis. This is an infection that can be caused by bacteria which enters the bloodstream and attaches itself to the heart valve or cardiac blood vessel. This vegetation which grows within the heart valve or vessel and can result in serious heart damage or death related to emboli.

Test Taking Tip

Patient education which surrounds medication therapy is extremely important. Focus your studies on pharmacologic patient education.
