How has psyllium fiber been successfully administered via feeding tubes?

• A. By diluting 1 tsp with 80 mL water, inject by syringe and follow with 15 mL water flush
• B. Mixed with formula and infused with gravity feeding bag
• C. Directly as powder through the syringe
• D. Without dilution and no flushing

Answer: (A)

Psyllium fiber thickens considerably when it contacts water, so delivering it through a feeding tube requires thinning and a controlled delivery to prevent blockage. Diluting a small amount of psyllium in plenty of water creates a slurry that can be drawn into a syringe and pushed through the tube smoothly. Following the administration with a water flush helps push any remaining fibers through and keeps the tube patent, ensuring the entire dose is received. Mixing psyllium with formula and using gravity flow can leave the fiber too viscous to move reliably and increases occlusion risk, while administering the powder directly or without a flush is prone to clogging and incomplete delivery.
