Objective Structured Clinical Assessment (OSCA) Practice Exam

Identifying the causative organism before giving antibiotics is crucial in suspected meningitis. Obtaining blood cultures prior to antibiotic administration, when possible, helps detect bacteremia and identifies the specific pathogen and its antibiotic sensitivities. This allows clinicians to tailor therapy more precisely and optimize outcomes. Starting antibiotics promptly is important, but if you can draw blood cultures first, you preserve the diagnostic information that will guide targeted treatment.

Urine cultures, EEG, and chest X-ray don’t directly inform the organism causing meningitis or guide immediate antimicrobial choice in this scenario, so they’re not the priority before antibiotics.
