What type of tube is inserted through the nose to reach the stomach?

The type of tube that is inserted through the nose to reach the stomach is the nasogastric tube. This tube is specifically designed for providing nutritional support, administering medications, or removing gastric contents. Its placement through the nasal passage allows it to travel down the esophagus and into the stomach, facilitating direct access for various medical needs.

In contrast, the other tubes mentioned serve different purposes. The endotracheal tube is utilized to secure the airway and is inserted through the mouth or nose into the trachea, not the stomach. The oropharyngeal tube is intended to keep the airway open and is positioned in the oropharynx, while the tracheostomy tube is inserted directly into the windpipe through a surgical opening in the neck. These differing functions and insertion sites clarify why the nasogastric tube is the correct answer for accessing the stomach via the nose.
