Why is it important to avoid recontaminating the skin after initial prep?

• A. Recontamination negates prep benefits and increases SSI risk; maintain sterile field.
• B. It has no effect.
• C. It speeds up procedure.
• D. It improves drape adhesive.

Answer: (A)

After skin prep, the goal is to lower and maintain the skin’s microbial load so the sterile field remains intact throughout the operation. If the skin or sterile barriers become contaminated again, bacteria can be reintroduced, eroding the antiseptic benefits and increasing the risk of a surgical site infection. Maintaining a sterile field and avoiding recontamination preserves the effectiveness of the prep and protects the patient.

The other ideas don’t fit because: recontamination does have an effect on infection risk; it doesn’t speed up the procedure; and it doesn’t improve drape adhesion—drape adhesion relies on a clean, dry, intact barrier, not on recontaminating after prep.
