Final answer:
During NG tube placement, the patient should be in a high-Fowler's position. The NG tube spans from the nose to the stomach. Before first use, confirm the tube's placement, and if the tube is on suction, turn it off when administering oral meds.
Step-by-step explanation:
NG Tube Placement and Care
The patient should be in a high-Fowler's position during NG tube placement to facilitate the passage of the tube and reduce the risk of aspiration. The NG tube goes from the nose to the stomach, via the esophagus. A Salem sump is a type of NG tube designed with dual lumens—one for removal of gastric contents and the other for venting air to prevent the vacuum effect when on suction.
The measuring points for determining the length of insertion typically involve measuring from the nose to the earlobe and then from the earlobe to the xiphoid process. If the client starts to gag, it is essential to pause and allow them to catch their breath, but if they can tolerate it, continue with the placement. Before using the NG tube for the first time, confirm placement by aspirating gastric contents and checking the pH, or by obtaining an x-ray.
If the NG tube is on suction, you should temporarily turn off suction when giving meds PO to ensure the medication reaches the stomach. If a patient vomits during the procedure, stop the insertion, clear the airway, and reassess before continuing.
