What is the correct intraabdominal CO₂ pressure maintained during most laparoscopic procedures in adults?
Answer: 10–15 mmHg
Standard pneumoperitoneum for laparoscopic surgery in adults is maintained at 10–15 mmHg to provide adequate visualization while minimizing physiologic stress.
Which OR lighting system provides the most shadow-free illumination of the operative field?
Answer: Multi-source LED overhead surgical lights
Multi-source LED surgical lights illuminate from multiple angles simultaneously, eliminating shadows and providing consistent, color-accurate lighting of the operative field.
When is it appropriate for the surgical technologist to break scrub during a procedure?
Answer: Only with the surgeon's permission and when relieved by another scrubbed person
The surgical technologist should break scrub only when relieved by another qualified scrubbed person, and only with team communication, to maintain sterile field continuity.
What is the primary purpose of a sterile drape fenestration (opening)?
Answer: To expose only the operative site while keeping surrounding areas covered
The fenestration exposes only the intended operative site, providing a controlled sterile field while keeping all surrounding tissue covered.
Which AORN standard requires that the surgical site be verified using a 'time-out' before incision?
Answer: Universal Protocol / Joint Commission National Patient Safety Goals
The Universal Protocol, a Joint Commission National Patient Safety Goal, mandates a pre-incision time-out to verify patient identity, procedure, and site.
What is the role of the surgical technologist during the time-out?
Answer: To actively participate and confirm patient identity, site, and procedure
All OR team members, including the surgical technologist, must actively participate in the time-out and verbally confirm the required safety information.
Which patient position is most commonly used for procedures on the perineum, rectum, and gynecologic organs?
Answer: Lithotomy
The lithotomy position, with legs elevated and abducted in stirrups, provides optimal access to the perineum, rectum, and pelvic organs.
