A client has a gastrostomy tube with continuous enteral feedings. Which intervention should the nurse include?

• A. Change feeding bag and tubing every 72 hours.
• B. Flush tube with 30 mL of water every 4 hours.
• C. Keep head of bed elevated at 15 degrees.
• D. Place enough formula in the feeding bag to last for 8 hours of continuous feeding.

Answer: (B)

Maintaining the tube’s patency is essential during continuous enteral feeding, and regular water flushes accomplish that by clearing residual formula and mucus from the lumen so the feed can flow smoothly. Flushing with about 30 mL of water every 4 hours helps prevent clogging that can interrupt the continuous infusion and keeps hydration steady without introducing concentrated feeds into the system. Reasoning about the other practices: changing the feeding bag and tubing every 72 hours is too infrequent and raises infection and contamination risks; head-of-bed elevation should be higher, typically 30–45 degrees, to reduce aspiration risk during and after feeds (15 degrees is insufficient); and having enough formula in the bag to last 8 hours for a continuous system increases the chance of bacterial growth and tubing occlusion, whereas shorter hangs and regular changes are safer.
