Cardiac Question #19
The nurse is caring for a client with a new prosthetic cardiac valve and is preparing discharge teaching. During discharge teaching, the nurse should provide education on the importance of antibiotic prophylaxis prior to which of the following?
- When exposed to influenza or pneumococcal pneumonia
- Prior to the next cardiac stress test
- Dental procedures
- Prior to any trip outside the United States
Phrophylactic antibiotics are recommended prior to dental procedures to help prevent infective endocardities which can occur following manipulation of gingival tissue or periapical regions of the teeth, or for injury to oral mucosa during dental procedures. Infective endocarditis occurs when bacteria from another part of the body enter and spread through the bloodstream and attach to areas of the heart. This spread may be the result of vegetation when endocardial tissue abnormalities induce deposits of fibrin and platlets which can lead to bacterial colonization.
