How much formula should be poured into an open administration set?

• A. 8-12 hour supply
• B. 24 hour supply
• C. 4 hour supply
• D. 2 hour supply

Answer: (A)

Open administration sets expose formula to the environment and handling, so the safety goal is to limit how long the opened product sits in the set. Pouring enough formula to run the infusion for about 8–12 hours keeps the exposure practical—you don’t have to repour constantly, which lowers contamination risk and reduces handling. At the same time, it avoids having a full day’s supply sitting open, which could lead to contamination or stability issues if the line is left in place too long. In contrast, pouring a 24-hour supply increases the window for microbial growth or spoilage; pouring only 2–4 hours would require more frequent handling and changes, elevating the risk and workload. Always follow your facility’s policy and the product’s stability guidance for opened PN solutions.
