How should skin prep be adapted for procedures involving the groin or axilla?

• A. Ensure thorough coverage of the involved skin, avoid mucous membranes, and follow site-specific protocol to minimize contact with non-target areas.
• B. Prep only the incision area to save time.
• C. Use only alcohol-based prep on mucous membranes.
• D. Do not prep groin/axilla to avoid irritation.

Answer: (A)

When prepping groin or axilla, the goal is to cover all skin that will be in the sterile field while protecting mucous membranes and non-target areas. Those regions have folds, moisture, and higher bacterial load, so bacteria can linger in surrounding skin if you only treat the exact incision line. Applying the antiseptic to the entire involved area reduces residual organisms and helps prevent contamination of the surgical field. Following a site-specific protocol ensures the right antiseptic choices, application technique, and contact time for the anatomy involved, plus proper draping to keep non-target areas out of contact with the prep. Avoid exposing mucous membranes to skin prep, as this can cause irritation or chemical injury. Skipping prep or limiting it to only the incision area increases infection risk, and using prep solely on mucous membranes is inappropriate.
