Which statement about sterilizing wrapped instruments is incorrect?

The statement regarding the removal of packs immediately after sterilization is incorrect because it is important to allow sterilized items to cool down and dry within the sterilizer before they are removed. This process reduces the risk of contamination and ensures that the integrity of the packaging is maintained. If items are taken out prematurely while still wet or hot, they can trap moisture that might lead to microbial growth or compromise sterilization.

In addition, proper cooling and drying allow for the formation of steam or vapor to escape, which can also help in preventing condensation on the instruments, ensuring they remain sterile. The other statements about the arrangement of perforated trays, non-perforated containers, and peel-packs reflect established best practices that optimize air circulation and steam penetration, which are critical factors for effective sterilization.
