a. The instrument set indicated on the surgeon’s preference card was placed on the ring stand or table and opened by the circulator. Figure 3-20 shows one such instrument set.

b. The scrub takes a hand towel from the linen pack, rolls the towel, and places it on the back table on which the instruments are to be arranged. The towel makes it easier to pick up the instruments from the back table.

c. The scrub then checks the instrument set sterilization indicator. If the sterilization indicator is acceptable, he proceeds to move the contents of the instrument pan to the back table. If the sterilization indicator does not show adequate sterilization, the instrument set is rejected and the scrub must regown and perhaps reglove.
