How many minutes after the sterile chime should service begin?

• A. 8 to 12 minutes
• B. 12 to 15 minutes
• C. 15 to 20 minutes
• D. 5 to 10 minutes

Answer: (B)

The timing after the sterile chime is about ensuring items are ready for use without compromising sterility or slowing the workflow. The 12 to 15 minute window is the practical range because it typically allows enough time for sterilized packs and instruments to dry and cool, and for staff to complete the final checks and set up the service quickly. Starting too soon can mean handling items that are still warm or damp, risking contamination or damage to the sterile field. Waiting too long can delay the schedule and create bottlenecks, reducing efficiency. This interval balances safety with efficiency, making 12 to 15 minutes the best fit.
