What should the nurse do with the residual volume before administering a nasogastric tube feeding?

Pouring back the residual volume into the nasogastric tube through a syringe is the correct approach because it helps to ensure that the patient receives all the nutrients and fluids that are already in their stomach. The presence of residual volume can indicate how well the patient is tolerating the feeding, but if the residual is within an acceptable range, it is often appropriate to return it before administering additional formula to prevent the loss of important nutrients and fluids.

This practice also aligns with the guidelines for managing tube feedings, where maintaining the patient's nutritional status is crucial. By returning the residual, the nurse also aids in preventing further complications, such as aspiration, which can occur if a significant amount of residual is left in the stomach. It is essential to make sure that the residual volume is within safe limits before doing this, demonstrating the appropriate application of clinical judgment.
