Which practice best describes maintaining enteral tube patency?

• A. Regular water flushes
• B. Saltwater flushes
• C. Oil flushes
• D. No flushes

Answer: (A)

Maintaining enteral tube patency depends on regularly flushing the lumen to rinse away residual formula and medications and prevent drying or plugging. Water is the best choice because it is safe, readily tolerated, and does not add solutes or fats that could complicate the tube environment. Regular water flushes keep the tube open between draws of feeds and meds and after residual checks, helping ensure the prescribed nutrition is delivered reliably. Using saltwater could introduce excess salt and risk fluid and electrolyte imbalances, especially in vulnerable patients. Oil flushes may leave lipid residues that are hard to clear and can contribute to clogging. Not flushing at all allows secretions and residue to dry and form clogs, making administration difficult and increasing the risk of tube blockage.
