Aseptic technique is best described as:

• A. Procedures that ensure sterility to prevent infection.
• B. Practices that maintain sterility to prevent infection.
• C. A method of completely eliminating all microorganisms.
• D. A protocol for sterilizing the environment.

Answer: (B)

Aseptic technique focuses on preventing infection by keeping the sterile field intact through deliberate practices during procedures. This is best described as practices that maintain sterility to prevent infection because it emphasizes ongoing actions—hand hygiene, sterile gloves, proper instrument handling, and maintaining a clean, sterile field—to minimize contamination. It acknowledges that absolute sterility in every moment is not guaranteed in real life, but the goal is to continually uphold sterility to reduce infection risk. It’s not about completely eliminating all microorganisms, since some microbes are always present in the environment, and it isn’t solely about sterilizing the environment, which misses the emphasis on the continuous, careful practices used during procedures.
