This comprehensive practice assessment is designed to evaluate knowledge and competency essential for
surgical technologists seeking certification in Illinois. The exam tests critical skills including preoperative
patient preparation, intraoperative assistance, sterile field maintenance, equipment handling, and emergency
response protocols. Questions are presented in multiple-choice and scenario-based formats that mirror the
actual certification examination structure. Emphasis is placed on real-world clinical application, clinical
decision-making, regulatory compliance, and professional standards that surgical technologists must
demonstrate in operating room settings. This assessment prepares candidates for the practical challenges
they will face in healthcare facilities across Illinois.
Section One: Questions 1–100
,Question 1
During preoperative preparation, what is the maximum recommended time a surgical technologist should allow
for skin antisepsis to achieve optimal microbial reduction?
A. 1-2 minutes
B. 3-5 minutes
C. 7-10 minutes
D. 15-20 minutes
🟢 B. 3-5 minutes
🔴 RATIONALE: Current surgical guidelines recommend 3-5 minutes of adequate contact time for surgical
skin antisepsis agents (such as chlorhexidine gluconate or iodine-based solutions) to achieve optimal microbial
reduction. Less time may not provide adequate antimicrobial effect, while longer times do not significantly
improve outcomes and may increase skin irritation.
Question 2
Which sterilization method is most appropriate for heat-sensitive surgical instruments containing plastic
components?
A. Steam autoclaving at 121°C
B. Dry heat sterilization at 160°C
C. Ethylene oxide gas sterilization
D. None of the above
🟢 C. Ethylene oxide gas sterilization
,🔴 RATIONALE: Ethylene oxide (EtO) gas sterilization is the preferred method for heat-sensitive instruments,
including those with plastic components, rubber, and electronic elements. Steam autoclaving and dry heat
would damage these materials. EtO penetrates packaging effectively and does not degrade heat-sensitive
materials.
Question 3
A patient with a known penicillin allergy is scheduled for colorectal surgery. Which antibiotic prophylaxis
alternative is most appropriate?
A. Cefazolin
B. Vancomycin
C. Ampicillin
D. Penicillin G
🟢 B. Vancomycin
🔴 RATIONALE: For patients with severe penicillin allergies, vancomycin is the recommended alternative for
surgical prophylaxis in colorectal procedures. Cefazolin is a cephalosporin with potential cross-reactivity.
Ampicillin and Penicillin G are penicillins and contraindicated.
Question 4
What is the primary responsibility of the surgical technologist during the count procedure?
, A. Document the count in the patient's medical record
B. Perform the count with the circulator and announce results clearly
C. Adjust the count if instruments appear missing
D. Only count sponges, not instruments
🟢 B. Perform the count with the circulator and announce results clearly
🔴 RATIONALE: The surgical technologist and circulator jointly perform all counts (sponges, instruments,
sharps) and must announce results clearly to ensure accuracy. Documentation is the circulator's responsibility.
The count cannot be adjusted without locating missing items.
Question 5
Which anatomical structure is directly visualized during a cholecystectomy?
A. Common bile duct
B. Pancreatic duct
C. Hepatic portal vein
D. Splenic artery
🟢 A. Common bile duct
🔴 RATIONALE: During cholecystectomy (gallbladder removal), the common bile duct is directly visualized
and carefully identified to avoid injury. The cystic duct and cystic artery are ligated and cut. The pancreatic
duct, hepatic portal vein, and splenic artery are not directly visualized in this procedure.
