Sorry should have been more specific. Patients have already had chlorohexidine scrub Preop. We currently use iodine solution to paint surgical site. Two nurses paint patients chest, abdomen, groins and both legs circumferentially to ankles. The legs are free limb draped (using a perigroin drape) and the unprepped feet are in isolation bags. There are two surgical sites here. The chest and the legs. Should one nurse be only painting the chest? While the other is prepping the legs? Should the "leg nurse"be using separate paint brushes for each leg?
