3. True or false: Skin preps should always be applied in a circular
motion, from clean to dirty areas.
False. Don't automatically assume that all preps require the circular
motion that used to be the standard. Instead, AORN recommends
reading the manufacturer's directions for use. Generally, CHG formu-
lations require a back-and-forth scrubbing motion over the site, start-
ing with the least contaminated area and moving to the most contami-
nated areas. For povidone-iodine solutions, you typically want to use
a circular application, again moving from clean to dirty areas.
Regardless of technique, apply the prep in an area that is large enough
to allow for an extension of the incision, additional incisions, drain
placement or shifting of the drapes, says AORN.
4. Most alcohol-based preps need a dry time of at least
____________________.
a. 3 minutes
b. 5 minutes
c. 12 minutes
a. 3 minutes. While it's important to read the product's directions for
use, most prep manufacturers say preps that contain isopropyl alcohol
and give off flammable vapors should dry for at least 3 minutes before
draping the patient or activating an ignition source, such as an electro-
cautery device. AORN also notes that it is important to not let the prep
pool during application — if excess solution drips off of the patient,
remove soaked materials such as drapes, gowns and towels before
using an electrosurgical device.
