Which is the most appropriate initial step in suspected sepsis?

• A. Start broad-spectrum antibiotics immediately
• B. Provide IV fluids and oxygen
• C. Place patient in isolation
• D. Obtain blood cultures before antibiotics

Answer: (D)

In suspected sepsis, the priority is to identify the causative organism before starting targeted therapy. Drawing blood cultures first preserves the ability to detect the specific pathogen and its antimicrobial sensitivities, which guides appropriate narrowing or adjustment of antibiotics as results come back. While initiating broad-spectrum antibiotics promptly is crucial, doing cultures before antibiotics maximizes diagnostic yield and helps tailor treatment rather than relying on empiric therapy alone. In practice, you can start antibiotics quickly if needed, but aim to obtain blood cultures as the first step whenever feasible so you don’t obscure the pathogen with early antimicrobial exposure.
