Which action is initially taken by the nurse to verify the correct position of a newly placed small-bore feeding tube?

The initial action taken by the nurse to verify the correct position of a newly placed small-bore feeding tube is to place an order for an x-ray film examination to check the position. This method is considered the gold standard for confirming tube placement because it provides a clear and accurate visualization of the tube's location. An x-ray can effectively show whether the tube is correctly positioned in the stomach or has advanced into the lungs, reducing the risk of aspiration, which could lead to serious complications such as pneumonia.

While other methods, such as testing the pH of gastric contents or auscultating over the gastric area, can be used to obtain additional confirmation of tube placement, they are not as definitive as an x-ray. These methods rely on certain assumptions that may not always hold true, making them less reliable than a radiographic evaluation. Additionally, confirming the distal mark on the feeding tube is important for placement documentation but does not verify the actual position once the tube is placed. Therefore, placing an order for an x-ray is the most reliable and appropriate initial step.
