Which word completes this statement: Catheterization is a ______ procedure.

Which word completes this statement: Catheterization is a ______ procedure.

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

Answer: (A)

The key idea is that catheterization is performed using sterile technique to prevent introducing infection. To insert a catheter, you use sterile supplies (catheter, gloves, drapes) and create a sterile field, then keep that field uncontaminated throughout the procedure. That level of cleanliness aims to eliminate all viable microorganisms at the moment of insertion, which is what "sterile" means in this context. Aseptic refers to practices designed to minimize contamination, but it describes the approach rather than guaranteeing a completely free-field condition. In catheterization, the standard description is that the procedure is sterile because the goal is to be free of microorganisms during insertion, not merely to reduce contamination. Non-sterile or contaminated would imply a higher risk of infection, which is inappropriate for this procedure.
