Which infection requires fast antibiotic administration with a 45-minute target?

• A. Meningitis (45 min)
• B. Sepsis (1 hour)
• C. Severe
• D. Pneumonia

Answer: (A)

Rapid antibiotic therapy is crucial when a bacterial CNS infection is suspected because delays dramatically worsen outcomes. Bacterial meningitis can progress quickly, and starting empiric antibiotics as soon as meningitis is suspected significantly reduces mortality and long-term neurological damage. In many clinical training contexts, a very short window—around 45 minutes from presentation—to administer the first dose is emphasized for meningitis to reflect how time-sensitive this infection is.

Sepsis also requires prompt treatment, but the commonly cited target is within about 1 hour of recognition, not 45 minutes. Pneumonia, while serious, does not have a universal 45-minute antibiotic window in standard guidelines. Thus the infection with the strict 45-minute treatment target here is meningitis.
