Why is flushing the tube with water before and after each medication recommended?

• A. To improve flavor
• B. To avoid physical interactions between medications and between medications and formula
• C. To prevent bacterial growth
• D. To measure dose

Answer: (B)

Flushing between and after medications is mainly about preventing interactions and ensuring the full dose is delivered through the tube. When you flush, you clear the lumen of residual formula or previously administered meds, so the next drug isn’t altered by contact with other drugs or with formula. This reduces the risk of chemical or physical interactions, such as precipitation or reduced absorption, and helps keep the tube patent so doses aren’t blocked. The flush after administration also pushes the medication through the tube, making sure the entire dose reaches the stomach. Flavor, bacterial growth control, or precise dose measurement aren’t the primary purposes of this practice.
