What should the nurse do to prevent clogging of a percutaneous gastrostomy tube?

Flushing a percutaneous gastrostomy tube with 30 mL of water before and after medication administration is the best practice to prevent clogging. This amount is generally sufficient to clear the tube of any residual formula and to ensure that the medication is adequately mixed and delivered without obstruction. Flushing before administration helps to prepare the tube for the medications, while flushing afterward ensures that all the administered medication is passed through the tube and any remaining residues are cleared away.

Using a larger volume like 30 mL is effective in maintaining patency and helps minimize the build-up of any particles that could contribute to clogging. This ergonomic approach is particularly important in managing patients with enteral feeding tubes, as they often require multiple medications and might be prone to tube obstruction if not handled correctly.

The inappropriate options include flushing with only 10 mL, which may not be sufficient to prevent clogging, especially if thicker medications are administered. Using milk to flush the tube isn't advisable, as it could leave residues that could potentially lead to obstruction. Additionally, administering all medications simultaneously with tube feeding can complicate clear delivery and further increase the risk of clogging the tube with solid or viscous substances. Flushing optimally before and after medication administration is essential for a
