Which method is recommended for checking gastric residual volumes (GRVs) during the first two days of tube feeding?

• A. Use a small-bore feeding tube and a 5 mL syringe to check GRVs.
• B. Use a standard feeding tube and a 30 mL syringe to check GRVs.
• C. Use a large-bore feeding tube and a 60 mL syringe to check GRVs the first two days of feeding.
• D. Check GRVs only if there are signs of feeding intolerance.

Answer: (C)

When you’re initiating tube feeding, you want to obtain an accurate measure of what remains in the stomach to judge tolerance and prevent overfeeding. A large-bore feeding tube allows thicker gastric contents to be aspirated more reliably and reduces the risk of clogs. A 60 mL syringe provides sufficient suction to pull out residual contents without underestimating the volume. Smaller syringes or smaller-bore tubes can under-aspirate thick contents or clog, giving a falsely low GRV and potentially leading to inappropriate feeding decisions. Checking GRVs in the early feeding period with this setup helps you gauge tolerance before advancing the rate or volume of feeds.
