The nurse is concerned that a client is at risk for developing infective endocarditis. What information in the client’s recent history is a possible cause infective endocarditis?

Infective endocarditis is often preceded by transient bacteremia, which allows oral or systemic flora to enter the bloodstream and adhere to cardiac endothelium. Patients with structural heart defects or prosthetic material are especially vulnerable when invasive procedures disrupt mucosal barriers, permitting high concentrations of bacteria to circulate. A. Dental procedures, such as an impacted tooth extraction, involve significant manipulation of the gingival tissue, which is highly vascular and colonized with various streptococcal species. This trauma allows bacteria to enter the venous system and migrate to the heart, potentially colonizing susceptible heart valves and forming vegetations. B. Benign prostatic hyperplasia (BPH) is a common condition involving the enlargement of the prostate gland, which can cause urinary obstruction. While it may lead to urinary tract infections, it is not a direct or recognized primary cause of the bacteremia specifically associated with the onset of infective endocarditis. C. Family medical history, such as a sister being treated for chronic renal failure, does not impact the client’s personal risk for developing an endocardial infection. Risk factors must be specific to the individual’s own physiological status, such as personal history of valve disease or personal history of intravenous drug use. D. Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage. It is a non-inflammatory, non-infectious condition. Routine treatment for osteoarthritis, such as analgesics or physical therapy, does not involve the systemic introduction of pathogens into the bloodstream and does not increase endocarditis risk.
