Educate the client on what is going to take place. Instruct client to relax and breathe normally while occluding one naris. Then repeat this action for the other nare. Select the nostril with greater airflow.

Determine the length of the tube to be inserted. Measure the distance from the tip of the nose to the earlobe to the xiphoid process (NEX) of the sternum.

Begin inserting the tube. Have the client relax and flex their head toward their chest after the tube has passed through the nasopharynx.

Encourage the client to swallow by taking small sips of water when possible. Then advance the tube as the client swallows.

Advance the tube each time the client swallows until you reach the desired length.

Temporarily anchor the tube to the nose with a small piece of tape.

Verify tube placement with a radiograph. Check agency policy for specific guidelines.
