What is the preferred flush solution to maintain feeding tube patency?

• A. Normal saline
• B. Tap water
• C. Water
• D. Sterile water

Answer: (C)

Flushing a feeding tube is done to keep the lumen open by removing residual formula and medications. Water is the preferred flush because it is nonnutritive and neutral, so it dissolves and washes away residues without adding solutes that could interact with the formula or medications or alter electrolyte balance in the small volumes used. It’s also readily available and inexpensive, making it practical for routine maintenance. In most settings, this means flushing with a small amount of water before and after feeds and after medications to prevent clogging. In patients with special risks or when water quality is uncertain, institutional policy may specify sterile water or another option, but for routine patency maintenance, plain water is the standard choice.
