Before, between, and after medication administration, what volume of water flush is recommended?

• A. 5 mL
• B. 10 mL
• C. 15 mL
• D. 30 mL

Answer: (C)

Flushing with a moderate, consistent volume helps keep the enteral tube patent and ensures each medication is delivered fully without mixing with formula or causing tube occlusion. Using 15 mL of water before, between, and after each medication is a common standard because it is large enough to clear the lumen and push the medication through, yet not so large as to add excessive fluid burden for most adults. A smaller amount, like 5 mL, may not effectively clear residual medication or formula; 10 mL might be insufficient in some situations; and 30 mL can unnecessarily increase fluid load, which could be risky for patients with limited fluid tolerance. Therefore, 15 mL is the best balance for maintaining patency and ensuring proper dose delivery in typical adult use.
