What constitutes a sterile pack and what is required to maintain sterility?

• A. A sterile pack is intact, sealed, and dry; handle only at the outer edge, avoid moisture, and inspect packaging before opening.
• B. A sterile pack can be damp as long as it seals later.
• C. A pack only needs to be sealed; dryness is not necessary.
• D. A sterile pack can be opened from the center.

Answer: (A)

Maintaining sterility relies on the packaging acting as an effective barrier to microorganisms. A sterile pack must be intact, sealed, and dry to keep that barrier uncompromised. Moisture can weaken the seal and wick into folds, allowing bacteria to reach the contents, so a damp pack cannot be trusted to remain sterile. Handle the pack only at the outer edge to avoid touching the sterile contents and to minimize the risk of transferring contaminants from hands or surfaces. Always inspect the packaging before opening for tears, punctures, moisture, or compromised seals, and check the expiration or lot information. If any compromise is found, the pack should not be used. Opening from the center would expose the sterile contents to non-sterile surfaces, breaking the sterility.
