How often should administration sets for human breast milk be changed?

How often should administration sets for human breast milk be changed?

• A. Every 12 hours
• B. Every 4 hours
• C. Every 24 hours
• D. Every 48 hours

Answer: (B)

The main idea is infection prevention in enteral feeds. Expressed human milk is perishable and can harbor bacteria; as it sits in tubing and reservoirs—especially if warmed during administration—bacteria can multiply. Changing the administration set every 4 hours minimizes the time the milk spends in contact with the tubing, reducing contamination risk for the infant. Longer intervals allow more bacterial growth and potential downstream issues such as infection or occlusion, so those options aren’t appropriate for routine practice with human milk feeds.
