Final answer:
The priority action when a tube feeding stops infusing is to check for tube placement to ensure it is properly located and to avoid serious complications.
Step-by-step explanation:
If a nurse notices that the tube feeding has stopped infusing for a patient receiving continuous enteral feedings via NG tube, the priority action is to check for tube placement. This involves verifying the position of the NG tube to ensure that it continues to be properly located in the stomach or intestine. If the tube has become dislodged or is not in the correct location, it could result in serious complications, such as aspiration or inadequate nutrition. After confirming the placement, the next steps can be taken, which might include assessing vital signs, documenting the incident, or irrigating the NG tube to resolve any potential clogging. It's vital to follow proper procedure and hospital protocol to safely manage enteral feeding issues.
