1

When unfolding and placing sterile drapes, which principle ensures that sterility of the operative field is preserved?

Place the fenestration first and then adjust the sides back toward the incision site
Touch any part of the drape with sterile gloves since the entire drape is sterile
Unfold drapes toward the body so they fall smoothly over the patient
Hold drapes high, touch only the outer edges, and unfold away from the body so only the top surface remains sterile

2

During draping for a laparotomy, a nurse drops one corner of a large sterile drape, and it brushes against the floor. What is the correct response?

Consider that corner contaminated and keep it outside the sterile field while continuing draping
Replace the entire drape immediately, even though only the corner touched the floor
Shake out the contaminated corner to remove debris and continue using it
Ignore the contact, as the antiseptic prep on the patient will protect against contamination

3

Why must a fresh drape be added if an existing one becomes saturated with antiseptic solution or blood during surgery?

Because saturated drapes become heavier and may slip off the patient
Because moisture reduces the antimicrobial activity of chlorhexidine or iodine
Because moisture enables strike-through, allowing microorganisms to migrate from the non-sterile underside to the sterile top
Because saturated drapes no longer adhere well to the patient’s skin

4

During hip replacement surgery, the surgeon notices the fenestrated drape is misaligned, leaving part of the incision site uncovered. The nurse attempts to reposition the drape toward the incision. What is the safest response?

Reposition the drape carefully toward the incision, since it has not touched any unsterile areas
Stop and replace the drape, since moving it back toward the incision risks dragging contamination into the sterile area
Cover the exposed area with an additional adhesive strip of sterile tape
Leave the drape as is and continue, since the antiseptic prep already reduced skin flora
