What is the most common nosocomial infection?

• A. Pneumonia
• B. Urinary Tract Infection (UTI)
• C. Surgical site infection
• D. Bloodstream infection

Answer: (B)

The question is testing which infection is most commonly acquired in a hospital setting. Catheter-associated urinary tract infections are the most frequent hospital-acquired infections. Indwelling urinary catheters breach the body’s natural defenses and create a surface for bacteria to form biofilms, allowing organisms to ascend into the bladder. The risk grows the longer the catheter remains in place, and since many inpatients require catheterization, these infections occur more often than other HAIs. While pneumonia, surgical-site infections, and bloodstream infections are important and serious, they occur less commonly overall. Preventing CAUTIs hinges on limiting catheter use to when truly needed, using sterile technique for insertion, maintaining a closed drainage system, keeping the collection bag below bladder level, and removing the catheter as soon as it’s no longer necessary.
