Which storage practice helps prevent contamination of PMU instruments?

• A. Store sterile items in sealed containers and use them before expiration
• B. Leave instruments exposed in open air
• C. Share storage with other equipment
• D. Pack items damp with disinfectant spray

Answer: (A)

Maintaining a sterile barrier until use is essential to prevent contamination of PMU instruments. Storing sterile items in sealed containers protects them from dust, microbes, moisture, and handling that could breach sterility, and using them before their expiration ensures the packaging and contents remain intact and effective. This approach minimizes the risk of introducing infections during procedures. Leaving instruments exposed to open air invites contamination, sharing storage can lead to cross-contamination with other equipment, and packing items damp with disinfectant spray can compromise sterility and leave moisture or residues that encourage microbial growth.
