C-Diff is the most frequently identified cause of which condition?

• A. Nosocomial diarrhea
• B. Community-acquired pneumonia
• C. Urinary tract infection
• D. Wound infection

Answer: (A)

The question is testing understanding that C. difficile infection most commonly presents as diarrhea acquired in a healthcare setting. In hospitals and long-term care facilities, many patients receive antibiotics, which disrupt the normal gut bacteria. This disruption allows C. difficile to overgrow and produce toxins that irritate and damage the colon, leading to watery diarrhea. Because antibiotic use and hospital exposure are common, C. difficile becomes the leading identified cause of diarrhea that starts in the facility or during a recent stay. It isn’t typically the cause of pneumonia, urinary tract infections, or wound infections, which arise from different pathogens and have different primary symptoms. Remember also that C. diff has spores that can spread in the hospital environment, so infection control and careful hand hygiene are important in preventing its spread.
