Is adding fresh formula to a formula that is already hanging in an administration set recommended?

Is adding fresh formula to a formula that is already hanging in an administration set recommended?

• A. Yes, it is recommended to add fresh formula to extend hang time
• B. It is acceptable to add fresh formula if the original is low
• C. It is mandatory to add fresh formula when a dose is due
• D. No, should be avoided

Answer: (D)

The important idea here is safety and stability of intravenous nutrition solutions. Once a formula is hanging in the administration set, adding fresh formula to it introduces contamination risk and can compromise the mixture’s stability. The system is not a closed, sterile environment for adding more solution mid-infusion, and introducing new formula can carry bacteria or alter the chemical balance, potentially causing precipitation or incompatibilities. Hang times and safety guidelines are built around using a fresh, properly prepared bag with a new administration set, not topping off an in-use line. So the recommended approach is to discard the current bag when a dose is due and start a new bag with a new set.
