What is the final location for a nasogastric (NG) tube?

Small intestine
Stomach
Esophagus
Colon

The correct answer is: Stomach

The final location for a nasogastric (NG) tube is the stomach. An NG tube is a flexible plastic tube that is inserted through the nose, passing down the esophagus, and is intended to reach the stomach. Its primary functions include delivering nutrition, removing gastric contents, and providing medications directly into the stomach. The design of the NG tube makes it suitable for use in the stomach, as it is aimed at facilitating various medical needs while minimizing complications. While the tube does pass through the esophagus, it does not remain there; its destination is the stomach, where it can carry out its intended functions effectively. Other potential locations mentioned, such as the small intestine and colon, are not typical destinations for a standard nasogastric tube. If feeding or drainage beyond the stomach is required, a different type of tube, such as a nasoenteric tube, would be used to bypass the stomach and reach the small intestine.
