Sterile technique to keep an area free from microorganisms and used for procedures like inserting an indwelling catheter or IV is called

• A. Surgical asepsis
• B. Medical asepsis
• C. Disinfection
• D. Sterilization

Answer: (A)

Maintaining a sterile field is the idea being tested. Surgical asepsis is the set of practices that keep an area free from all microorganisms during invasive procedures like inserting a catheter or IV line. This involves using sterile gloves, sterile instruments, and sterile drapes, with anything inside the sterile field remaining sterile and untouched by non-sterile items. Medical asepsis, in contrast, reduces microorganisms on surfaces and skin through hygiene and cleaning but does not create a truly sterile field. Disinfection aims to kill or reduce many pathogens on surfaces but doesn’t achieve complete sterility. Sterilization removes all forms of life from equipment, but it refers to preparing tools rather than describing the ongoing technique used during procedures. In short, the proper term describes the highly controlled sterile technique required to prevent infection when accessing the body with invasive devices.
