A procedure performed under sterile conditions is known as

• A. Aseptic Technique
• B. Sterile Procedure
• C. Clean Technique
• D. Disinfection

Answer: (A)

Aseptic technique is the process of performing procedures in a way that prevents contamination by microorganisms. It’s the set of practices used to maintain a sterile environment: thorough hand hygiene, using sterile gloves and instruments, sterilizing tools, and creating and preserving a sterile field so that pathogens cannot be introduced during an invasive procedure.

The other terms don’t fit as precisely. A sterile procedure can describe the outcome or setting but isn’t the standard way to refer to the practices that prevent contamination. Clean technique describes non-sterile handling, used for routine tasks that don’t require sterility. Disinfection means reducing or eliminating microbes on surfaces, not guaranteeing sterility during a procedure.
