Which statement about syringe size and feeding tube patency is correct?

• A. Using a small syringe does not increase pressure and is safe.
• B. A small syringe increases pressure and may cause feeding tube rupture.
• C. The syringe size has no impact on patency.
• D. Only large syringes should ever be used; otherwise you must remove the tube.

Answer: (B)

The key idea is that syringe size changes the pressure you generate when flushing a feeding tube. Pressure inside the tube is determined by how hard you push divided by the area of the syringe’s barrel. A small syringe has a smaller area, so pushing with the same force creates higher pressure. That higher pressure can stress the tube, potentially causing rupture or other damage and can worsen blockage if the tube isn’t able to flow. Using a larger syringe distributes the force over a bigger area, giving lower pressure for the same push and helping maintain patency safely. So a small syringe can increase pressure and may lead to tube rupture, making it the correct statement. If you encounter resistance, check for a kink, reposition the tube, or use a larger syringe and gentle, steady pressure rather than forcing with a small one.
