In wound care, which technique should be used to prevent contamination?

• A. Clean technique
• B. Aseptic technique
• C. Hand hygiene is optional
• D. Use non-sterile equipment

Answer: (B)

Aseptic technique focuses on keeping the wound and the surrounding environment free from microorganisms by using sterile supplies and strict practices. It combines thorough hand hygiene, sterile gloves, sterile instruments and dressings, and proper skin preparation to create a sterile field around the wound. By maintaining sterility throughout the procedure, it minimizes the chance of introducing pathogens and helps prevent infection.

Clean technique lowers contamination risk but does not guarantee a sterile field because it allows the use of non-sterile supplies and environments in some steps, which is not sufficient for high-risk wound care. Hand hygiene is essential and not optional part of the process, and using non-sterile equipment would compromise sterility and increase contamination risk.
