Which of the following is NOT a correct step to maintain asepsis during wound dressing using sterile technique?

• A. Maintain sterile field
• B. Keep hands above the waist
• C. Open sterile items on a non-sterile surface
• D. Avoid non-sterile contact with sterile items

Answer: (C)

Maintaining a sterile field is essential to prevent introducing microorganisms into a wound. Opening sterile items on a non-sterile surface compromises that boundary—the surface is likely contaminated, and as soon as you handle or set the sterile item on it, contaminants can transfer to the item, defeating sterility and increasing infection risk. To uphold asepsis, sterile items should be opened on a sterile surface or within the sterile field so they remain uncontaminated. Keeping hands above the waist reduces the chance of dirty clothing or body surfaces contacting the sterile area, and avoiding non-sterile contact with sterile items protects the integrity of the sterile supplies. These practices together preserve sterility throughout wound dressing.
