During preoperative skin preparation, how should scrubbing be performed?

• A. Start at the incision and scrub outward.
• B. Repeat scrubbing three times, with a new gauze each cycle.
• C. Soak small animals with rubbing alcohol.
• D. Ensure povidone-iodine is still wet when surgery starts.

Answer: (B)

The main idea is that preoperative skin prep works to reduce skin bacteria by applying antiseptic in several clean passes, keeping each pass fresh so contaminants aren’t reintroduced. Repeating the scrubbing three times with a new gauze for each cycle ensures that every pass uses a pristine material, maximizing the antiseptic’s effect and preventing recontamination from a used gauze. This approach also helps achieve adequate coverage and the required contact time for the antiseptic to work effectively. Soaking animals in rubbing alcohol isn’t a standard method for skin prep, and prep solutions like povidone-iodine or chlorhexidine should be used and kept on the skin for the recommended contact time, rather than relying on dryness or inappropriate alternatives.
