A nurse is about to administer an intermittent enteral feeding to a client who has an NG tube in place. Besides obtaining an x-ray, which of the following methods should the nurse use to verify the placement?
Inject air and listen for bubbling.
Test the pH of the gastric aspirate.
Measure the gastric residual.
Add food coloring to the formula.
The Correct Answer is B
This is done by aspirating a small amount of stomach contents and testing the pH using pH paper or a pH indicator strip. The pH of stomach contents is typically acidic (pH less than 5), indicating proper placement in the stomach.
Injecting air and listening for bubbling is not a reliable method to verify tube placement, as it can lead to complications such as pneumothorax.
Measuring gastric residual is done to assess the amount of gastric contents remaining in the stomach, but it does not confirm tube placement.
Adding food coloring to the formula is not a standard practice and does not provide reliable confirmation of tube placement.
X-ray is the gold standard method to confirm tube placement but is not typically done before every intermittent feeding unless there are concerns about tube placement
