,Introduction
This comprehensive assessment is designed to evaluate candidates' readiness for the Certified Surgical
Technologist certification examination. The exam measures essential skills and knowledge required for safe and
effective perioperative practice, including preoperative preparation, intraoperative technique, sterile
processing, and postoperative care. The assessment consists of multiple-choice and scenario-based questions
that emphasize real-world application and critical decision-making in surgical settings. Candidates will
demonstrate mastery of aseptic technique, equipment handling, patient safety protocols, emergency response,
and professional standards. Success on this exam indicates competency for entry-level surgical technologist
practice and adherence to current evidence-based guidelines in modern healthcare environments.
Section One: Questions 1–100
Question 1
The primary purpose of the surgical technologist's role during the preoperative phase is to:
A. Administer anesthesia to the patient
B. Prepare the sterile field and arrange instruments
C. Perform the surgical incision
D. Obtain the patient's surgical history
🟢 Correct answer: B
,🔴 RATIONALE: The surgical technologist's primary preoperative responsibility is preparing the sterile field
and arranging instruments for the procedure. Administering anesthesia is performed by the anesthesia
provider, the surgeon performs the incision, and obtaining surgical history is done by the nursing or medical
team.
Question 2
Which sterilization method is most appropriate for heat-sensitive instruments containing plastics?
A. Steam autoclaving at 121°C
B. Dry heat sterilization at 170°C
C. Ethylene oxide gas sterilization
D. Flash sterilization at 134°C
🟢 Correct answer: C
🔴 RATIONALE: Ethylene oxide gas sterilization is appropriate for heat-sensitive instruments including
plastics because it operates at lower temperatures (typically 30-60°C) and does not damage delicate materials.
Steam autoclaving and dry heat use temperatures that would damage plastics, and flash sterilization is also
high-temperature.
, Question 3
During a laparoscopic procedure, the surgical technologist should position the trocars:
A. In a straight line parallel to the midline
B. Forming a triangular configuration with the scope at the apex
C. Randomly based on surgeon preference
D. All clustered at the same insertion point
🟢 Correct answer: B
🔴 RATIONALE: Trocars should be positioned in a triangular configuration with the laparoscope at the apex to
provide optimal triangulation for instrument manipulation and visualization. This standard positioning allows
the surgeon to work effectively with both hands while maintaining proper camera view.
Question 4
The minimum exposure time for sterilization using a steam autoclave at 121°C and 15 psi is:
A. 3 minutes
B. 10 minutes
C. 15 minutes
D. 30 minutes
🟢 Correct answer: C
