Which statement best describes the relationship between skin prep and draping?

• A. They are unrelated steps.
• B. Skin prep is optional if drapes are secure.
• C. Draping is only relevant after skin prep has begun.
• D. Skin prep and draping are planned together to ensure the operative field remains clean.

Answer: (D)

Skin prep and draping are planned together to create and maintain a sterile operative field. Skin prep reduces the skin’s microbial load with antiseptic cleansing, while draping provides a sterile barrier that isolates the surgical area from non-sterile surfaces. Coordinating these steps ensures the antiseptically treated area stays within the sterile field established by the drapes, minimizing the risk of contamination. The idea that prep is optional if drapes are secure isn’t correct, since reducing skin flora is essential regardless of draping. Likewise, draping isn’t only relevant after prep has begun; the planning and sequencing are coordinated so the sterile field is established and preserved from the start.
