Before feeding through an NG tube, what is the first action?

• A. Check placement
• B. Flush with water
• C. Measure residual
• D. Auscultate bowel sounds

Answer: (A)

Verifying the tube’s placement is the first step before you start any feeding. Feeding into the lungs or another wrong location can cause dangerous complications like aspiration pneumonia, so you want to be certain the tube tip is in the stomach before delivering formula. The most reliable method is imaging that confirms the tube’s path and final position, but if imaging isn’t immediately available, clinicians may assess placement indirectly by aspirating gastric contents and checking the pH, keeping in mind this method isn’t perfect. After placement is confirmed, you would flush the tube with water to maintain patency and then proceed with the feeding or residual checks as your protocol dictates. Auscultating bowel sounds does not indicate where the tube is and isn’t used to verify placement.
