CST OR Efficiency & Case Flow 3 — Questions and Answers
Question 1: During a laparoscopic cholecystectomy, the scrub tech notices the laparoscope is fogging repeatedly. The MOST efficient intraoperative solution is:
- Requesting a full scope exchange from SPD, halting the case
- Warming the scope tip or applying anti-fog solution to clear the lens without interrupting flow (Correct answer)
- Asking the surgeon to proceed without visualization
- Documenting the issue and addressing it post-case
Correct answer: Warming the scope tip or applying anti-fog solution to clear the lens without interrupting flow
Warming the scope tip or using anti-fog solution is the standard rapid fix that restores visualization without requiring a scope exchange or case delay.
Question 2: The term 'block scheduling' in OR management refers to:
- Reserving OR time in defined blocks for specific surgeons or service lines to improve predictability (Correct answer)
- Blocking access to the OR to non-essential personnel
- Scheduling cases back-to-back with no turnover time allocated
- Using physical barriers between ORs during trauma cases
Correct answer: Reserving OR time in defined blocks for specific surgeons or service lines to improve predictability
Block scheduling allocates reserved OR time to specific surgeons or specialties, improving case volume predictability and resource planning.
Question 3: Which of the following BEST describes the scrub technician's role during the 'timeout' procedure?
- Leaving the sterile field to retrieve additional supplies
- Actively participating by verbally confirming the patient, procedure, and site (Correct answer)
- Observing silently while the surgeon leads the timeout
- Documenting the timeout in the anesthesia record
Correct answer: Actively participating by verbally confirming the patient, procedure, and site
Every member of the OR team, including the scrub tech, must actively participate in the timeout by confirming critical patient safety information.
Question 4: To minimize contamination risk during a long case, the scrub tech should:
- Periodically leave the sterile field to stretch
- Keep the sterile field compact, covered when not in active use, and avoid reaching over it (Correct answer)
- Allow the circulator to reach across the sterile field to hand instruments
- Open additional sterile supplies over the draped patient
Correct answer: Keep the sterile field compact, covered when not in active use, and avoid reaching over it
Maintaining a compact sterile field and covering it during pauses reduces the risk of contamination and helps the scrub tech maintain control during long procedures.
Question 5: What does 'case duration accuracy' measure in OR efficiency metrics?
- How quickly the anesthesiologist induces the patient
- The difference between predicted and actual case length, used to improve future scheduling (Correct answer)
- The time from patient arrival to discharge from PACU
- The number of instruments counted per case
Correct answer: The difference between predicted and actual case length, used to improve future scheduling
Case duration accuracy compares estimated versus actual OR times to refine future scheduling and reduce block time waste.
Question 6: When a case is added emergently to a full OR schedule, which action by the scrub tech BEST supports team efficiency?
- Refusing the add-on until the schedule clears
- Quickly reviewing the preference card, gathering supplies from the case cart, and communicating readiness to the team (Correct answer)
- Waiting for the charge nurse to fully set up the room
- Beginning setup without notifying the circulator
Correct answer: Quickly reviewing the preference card, gathering supplies from the case cart, and communicating readiness to the team
Proactively reviewing the preference card and mobilizing supplies speeds the room's readiness for the emergent add-on while keeping the team informed.
Question 7: Which metric BEST reflects overall OR suite efficiency?
- Total number of instruments sterilized per day
- OR utilization rate — the percentage of scheduled block time actually used for surgical cases (Correct answer)
- Number of preference cards updated per quarter
- Daily sterilizer load count
Correct answer: OR utilization rate — the percentage of scheduled block time actually used for surgical cases
OR utilization rate measures how effectively booked time is converted to actual surgical minutes, serving as the primary indicator of suite-wide efficiency.
