Final answer:
The nurse's priority when eneteral feeding through an NG tube stops is to flush the tube with warm water to clear any obstructions. If this does not resolve the issue, further steps like notifying the medical provider may be necessary.
Step-by-step explanation:
The priority action a nurse should take when noticing that the tube feeding has stopped infusing through an NG tube is to flush the tube with warm water. This initial step is essential to determine if the tube is obstructed. Flushing the tube can help clear any potential clogs and restore the flow of the enteral feeding. If flushing the tube does not resolve the issue, further action may be necessary, such as notifying the provider or considering tube replacement. Changing the formula is not a priority as it does not address an infusion stoppage caused by a potential tube clog.
