Which factor puts Mr. Carolis most at risk for developing an infection after surgery and catheterization?

• A. In-dwelling urinary catheter
• B. Age
• C. Poor nutrition
• D. Surgery

Answer: (A)

The main idea is that invasive devices significantly raise infection risk, especially an indwelling urinary catheter. When a catheter is left in place, it creates a direct pathway for bacteria to enter the urinary tract and it provides a surface for biofilms to form. These biofilms protect bacteria from the immune system and antibiotics, making catheter-associated urinary tract infections a common post‑operative complication. The catheter also serves as a reservoir for pathogens and increases the likelihood of contamination with routine care. While age, poor nutrition, and the surgery itself can influence how someone responds to infection, none are as directly linked to post‑operative infection risk as having an indwelling urinary catheter. Removing the catheter as soon as it’s no longer needed and ensuring proper catheter care are key steps to reduce this risk.
