What is an initial management step when bacterial endocarditis is suspected?

• A. Start IV antibiotics and obtain blood cultures.
• B. Start oral antibiotics.
• C. Immediate surgery.
• D. Reassure and discharge.

Answer: (A)

When endocarditis is suspected, the priority is to identify the causative organism quickly and start effective treatment. Collect blood cultures from multiple sites before or as soon as possible after starting therapy, because knowing the exact organism and its sensitivities guides targeted antibiotics. Begin intravenous antibiotics promptly, since parenteral therapy achieves reliable drug levels and can penetrate vegetations better than oral agents. Delay in treatment can lead to valve damage, embolic complications, and higher mortality, so reassurance or discharge is inappropriate. Surgery is reserved for specific complications or indications (such as heart failure, persistent infection despite antibiotics, or prosthetic valve endocarditis), not as the initial step.
