Question

question 53 1 pts a patient has native valve endocarditis (nve). while blood cultures are pending, which antibiotics will be ordered as empirical treatment? a beta - lactamase - resistant penicillin and an antifungal drug imipenem - cilastatin and ampicillin penicillin g and an aminoglycoside antibiotic vancomycin and quinupristin - dalfopristin

Explanation:

Native valve endocarditis is often caused by streptococci and staphylococci. Penicillin G is effective against streptococci and an aminoglycoside antibiotic provides synergistic activity and helps cover for possible resistant organisms while blood - cultures are pending. Antifungal drugs are not indicated as the causative agents are usually bacteria. Imipenem - cilastatin and ampicillin combination is not the typical empiric choice. Vancomycin and quinupristin - dalfopristin are not the first - line empiric agents for NVE.

Answer:

C. Penicillin G and an aminoglycoside antibiotic
