Which scrubbing method involves a specified number of strokes per anatomical plane?

The counted brush stroke method is the correct answer because it specifies a precise number of strokes for scrubbing each anatomical plane of the hands and forearms. This method is particularly important in surgical settings, where maintaining a sterile environment is vital to prevent infections. By counting the strokes for specific areas, this method ensures that all surfaces receive adequate attention and cleaning, thus enhancing the effectiveness of the scrub in reducing microbial load.

In contrast, the timed scrub method involves scrubbing for a set amount of time rather than focusing on a specific number of strokes per area. This could lead to uneven cleaning if not monitored carefully. The antiseptic hand rub method is a quick technique using alcohol-based solutions that do not involve scrubbing and are less time-consuming. The traditional scrub method, while thorough, typically does not have the rigorous stroke counting element that characterizes the counted brush stroke method, relying more broadly on clean technique over defined parameters.
