Certified Surgical Technologist (CST) Practice Exam

Which member of the surgical team is considered non-sterile?

1. Surgeon

2. Surgical assistant

3. Surgical Technologist

4. Circulator

The correct answer is: Circulator

The circulator is considered a non-sterile member of the surgical team. This role involves managing the overall environment of the operating room and ensuring that all necessary supplies and equipment are available for the surgical procedure. The circulator is responsible for activities such as obtaining sterile instruments, passing them to sterile team members, and keeping the sterile field organized. Being non-sterile, the circulator does not wear sterile attire and can interact with the outside environment, which is critical for maintaining communication with other medical personnel, handling medications, and fulfilling any requests that arise during the surgery. This role contrasts with that of the sterile team members, such as the surgeon, surgical assistant, and surgical technologist, who must maintain their sterile environment and avoid contamination throughout the procedure.
