Which intervention assists with maintaining feeding tube patency in the adult patient?

• A. administer medications through feeding tube with 5 mL of water
• B. use a 20 mL of smaller syringe to flush small-bore feeding tubes
• C. change feeding tube every 72 hours
• D. flush feeding tube with 30 mL of water every 4 hours during continuous feeding

Answer: (D)

Maintaining tube patency hinges on keeping the lumen clear with regular hydration. For adults on continuous feeds, flushing with a substantial volume of water at regular intervals prevents buildup of formula, residues, and medications that can clog the tube. This approach provides ongoing clearance during the entire infusion, reducing the risk of occlusion. Administering medications with only a small amount of water can leave residues that precipitate blockage, and using a very small syringe can generate high pressure that may damage the tube while still not effectively clearing it. Replacing the tube on a fixed schedule doesn’t address occlusion once it occurs and isn’t a patency-maintenance strategy. So, a routine, adequately volumed water flush during continuous feeding best maintains feeding tube patency.
