Why Sterile Field & Draping matters
Sterile Field & Draping is heavily weighted on the CST Certified Surgical Technologist (NBSTSA) because lapses in safety protocols directly threaten patient outcomes.
Sample Practice Questions (5)
1. When draping the patient for a laparotomy, sterile drapes should be placed:
- From the non-sterile area toward the sterile area (far to near)
- From the operative site outward (near to far), with the first drape placed closest to the incision site
- All four drapes placed simultaneously by different team members
- Starting with the drape farthest from the surgical team
2. During a total joint replacement, the circulating nurse opens a sterile implant tray to the field. The surgical technologist notices the internal chemical indicator strip has not changed color. What does this indicate and what should be done?
- The indicator confirms sterility; proceed with using the implant
- The sterilization conditions may not have been met; do NOT use the implant and notify the circulating nurse to obtain a replacement
- The indicator is only for external use and has no bearing on the contents' sterility
- Re-sterilize the implant tray using immediate-use steam sterilization (IUSS) and proceed
3. When donning a sterile gown, which area of the gown is considered sterile?
- The entire gown from neckline to hem
- The front of the gown from chest to waist level, and the sleeves from the cuff to 2 inches above the elbow
- Only the sleeves and gloved hands
- The front and back of the gown from shoulder to waist

- Hand the item directly to the surgical technologist
- Open the outer wrapper using sterile technique and present the contents or flip/drop them onto the sterile field without reaching over it
- Place the wrapped item on the back table for the ST to unwrap later
- Toss the item onto the sterile field from a distance of 3 feet
5. During a long surgical procedure, the surgical technologist notices a small hole in the fingertip of their right glove. No one else on the team has noticed. What is the MOST appropriate action?
- Cover the hole with a sterile adhesive bandage and continue
- Immediately step back from the sterile field, inform the team, and have the circulator assist with regloving using an open or assisted gloving technique
- Wait until the next convenient break in the procedure to change gloves
