Which of the following actions should not be performed when maintaining sterile items?

The action of packaging items in non-sterile containers is an important aspect of maintaining sterility. When sterile items are packaged in containers that are not sterile, there is a significant risk of contamination which would compromise the integrity of the sterile items. The purpose of maintaining sterile items is to prevent infections and ensure patient safety, and this cannot be achieved if the items are not properly packaged.

In contrast, controlling traffic in the storage area, monitoring cleanliness, and ensuring proper air circulation are all practices that contribute to maintaining a sterile environment and the integrity of sterile items. These actions help to minimize the risk of contamination and ensure that the storage area remains conducive to preserving sterility. Hence, packaging items in non-sterile containers is indeed the action that should not be performed in the context of maintaining sterile items.
