Which of the following is a reason that a bag may need to be unsealed?

• A. Mixes
• B. Re-bill
• C. For patient convenience
• D. When the bag is damaged

Answer: (A)

Opening a bag is done when you need to mix its contents with other ingredients to reach the correct final formulation. The unsealing step allows thorough blending and ensures the medication is prepared in the right concentration, while still following sterile technique to prevent contamination.

Other options don’t fit this purpose: re-bill is an administrative action, not a preparation step; unsealing for patient convenience isn’t appropriate because it can affect sterility and safety; and a damaged bag should not be unsealed—damaged packaging requires replacement or disposal to maintain safety.
