Which practice best promotes stock rotation when storing sterile supplies?

• A. Rotate stock to use oldest items first.
• B. Store updated items on top of older items.
• C. Keep stock in warm, humid areas.
• D. Store older items behind newer items.

Answer: (A)

Stock rotation means using the oldest sterile supplies first so nothing sits on the shelf past its expiration or compromises sterility. The best way to implement this is to place the oldest stock in the most accessible position and consistently pull from that front position, ensuring items are used in the order they were received. This approach, often called first in, first out, minimizes waste and keeps the sterility of supplies intact by honoring their shelf life.

If newer items are placed on top or in front of older ones, the older stock may not be used promptly and could expire or deteriorate, even though it is still sterile at the time. Storing supplies in warm, humid areas can hasten degradation of packaging and barrier integrity, increasing the risk of contamination. Keeping older items behind newer items also makes rotation easy to overlook, leading to older stock being neglected or forgotten.
