She underwent an uncomplicated tooth extraction approximately 6 weeks ago. Her vital signs include a temperature of 100.8 F, pulse of 83, blood pressure of 11077, and SpO2 of 97 on room air. On exam, you note a grade IIIVI holosystolic murmur at the apex radiating to the axilla as well as several red, painful nodules on her fingers. Which of the following is the next best course of action?? A: Obtain blood cultures x3 sites over 1 hour and start empiric antibiotics, B: Obtain blood cultures x3 sites over 24 hours and start antibiotics after culture results are available, C: Blood cultures are not needed. Start empiric antibiotics, D: Consult cardiothoracic surgery for mitral valve replacement, E: Start anticoagulation with heparin,  <response>: This is a patient with a history of mitral valve prolapse presenting with prolonged fevers, fatigue, anorexia, a new murmur, and subacute bacterial endocarditis SBE stigmata splinter hemorrhages. The key finding is the new murmur, which indicates worsening mitral regurgitation likely due to SBE. Blood cultures are needed to identify the organism and guide antibiotic therapy. Empiric antibiotics should be started promptly to prevent further valve damage and complications like embolic events. Surgery may be eventually needed but not as the immediate next step. Anticoagulation is not indicated in native valve endocarditis.B: Obtain blood cultures x3 sites over 24 hours and start antibiotics after culture results are available
