In a patient with suspected meningitis and high pretest probability, what is the recommended action?

• A. Order imaging first
• B. Start antivirals
• C. Obtain lumbar puncture before antibiotics
• D. Start antibiotics immediately

Answer: (D)

In suspected meningitis with high pretest probability, acting fast with treatment saves lives. Bacterial meningitis can progress rapidly, so starting intravenous antibiotics right away is the priority to reduce mortality and neurologic complications. If feasible, obtain blood cultures first, but do not delay antibiotics waiting for those results or for procedures like a lumbar puncture or imaging. Once antibiotics are started, you can pursue diagnostic steps (blood cultures, lumbar puncture, imaging) as appropriate, but these should not hold up initial therapy. In practice, empiric broad-spectrum antibiotics are given promptly, with dexamethasone considered early in appropriate cases, and imaging or LP performed after antibiotics if there are signs that these tests are urgently needed or if contraindications to LP exist.
