What step should be taken to ensure proper adhesion of the drape?

Ensuring proper adhesion of the drape is critical in maintaining a sterile field during any interventional radiology procedure. Allowing the skin to dry is essential because moisture can compromise the adhesive properties of the drape. When the skin is wet, the drape may not stick properly, which can lead to potential breaches in sterility or dislodgement of the drape during the procedure.

By allowing the skin to dry completely, you create an optimal surface for the adhesive on the drape to adhere securely. This practice minimizes the risk of contamination and helps to maintain a sterile environment, essential in preventing infection and ensuring patient safety during interventional radiological procedures.
