During surgical hand scrubbing, why is a new piece of gauze used for each scrubbing cycle?

• A. To prevent rubbing dryness
• B. To reduce contamination risk
• C. To increase scrubbing time
• D. To keep gauze from sticking

Answer: (B)

The goal of using a fresh gauze for each scrub cycle is to minimize contamination risk. When you scrub, you’re trying to remove as many microorganisms and debris as possible with each pass. If you reuse a gauze, you risk transferring microbes and skin oils from the used material onto areas you’ve already cleaned, or you could pick up more contaminants from the used gauze itself. A new gauze provides a clean surface to wipe away loosened material and prevents back-and-forth contamination, helping maintain a sterile, low-microbial hand surface before entering the sterile field. Other options don’t fit the main purpose: using new gauze to prevent rubbing dryness isn’t the priority in a sterile technique, increasing scrubbing time isn’t the objective and isn’t desired, and keeping gauze from sticking isn’t the underlying reason for changing gauze between cycles.
