Catheterization is described as which type of procedure?

• A. Sterile
• B. Non-sterile
• C. Aseptic
• D. Contaminated

Answer: (A)

The main idea is that invasive catheter placement must be performed using sterile technique to prevent introducing microorganisms into a normally sterile body space. Catheterization involves inserting a device into the urethra and into the bladder, which is a mucosal surface that should remain free of contaminants. To achieve this, everything involved—the catheter, gloves, drapes, and antiseptic prep—must be sterile, and steps are taken to maintain a sterile field throughout the procedure. This absolute level of sterility helps prevent catheter-associated infections, including urinary tract infections and potential sepsis. While aseptic principles are about reducing contamination, the goal here is true sterility because the device enters a sterile environment. Non-sterile or contaminated approaches would significantly raise infection risk, and aseptic would not fully capture the need for a completely sterile field in this context.
