What is the first step in inserting a nasogastric (NG) tube?

The first step in inserting a nasogastric (NG) tube involves measuring the distance of the tube. This step is crucial because it ensures that the tube is the correct length to reach the stomach safely and effectively. Typically, the measurement is taken from the tip of the nose, along the midline of the face, to the earlobe, and then down to the xiphoid process (the lower part of the sternum). This process helps in determining how far the tube needs to be inserted to avoid complications such as coiling in the esophagus or not reaching the stomach properly.

Measuring the tube distance lays the groundwork for proper placement and minimizes the risk of injury to the patient. After this measurement is taken, other steps can follow, such as lubricating the end of the tube to facilitate smooth insertion.
