Where should an NG tube ideally be located on radiographic imaging?

• A. Above the diaphragm in the esophagus.
• B. In the small intestine.
• C. Below the diaphragm on the left side in the stomach.
• D. In the right atrium.

Answer: (C)

NG tubes are intended to terminate in the stomach so they can drain or deliver feedings safely. On a radiograph, the key is to have the tube pass below the diaphragm and project into the stomach region, which sits in the left upper abdomen. This position ensures the tube’s tip is in the stomach rather than the esophagus, right atrium, or small intestine. A misplacement above the diaphragm means the tube is still in the esophagus, which risks aspiration, while a tip in the heart or elsewhere can be dangerous. So the ideal location is below the diaphragm within the stomach, typically on the left side of the imaging field.
