A nurse is caring for a client who has a bowel obstruction and a new prescription for the insertion of a nasogastric tube. Which of the following interventions should the nurse take when inserting the nasogastric tube?

Choice A rationale Instructing the client to place his chin to his chest and swallow is the correct technique for nasogastric tube insertion. Tucking the chin closes off the trachea and opens the esophagus. The act of swallowing helps propel the tube downward into the esophagus rather than the larynx. This coordination reduces the risk of accidental tracheal intubation and makes the passage of the tube more comfortable and efficient for the patient while ensuring the tube reaches the stomach. Choice B rationale Gagging is a normal physiological response during the insertion of a nasogastric tube as it passes the posterior pharynx. The nurse should not withdraw the tube completely if the client gags. Instead, the nurse should briefly pause, encourage the client to take a few sips of water or take deep breaths to relax, and then continue with the insertion. Withdrawal is only necessary if the client shows signs of respiratory distress, such as coughing, choking, or becoming cyanotic. Choice C rationale Placing the client in a supine position is contraindicated for nasogastric tube insertion. The client should be in a high-Fowler's position with the head of the bed elevated to at least 60 to 90 degrees. This upright position uses gravity to help the tube descend and significantly reduces the risk of aspiration if the client vomits during the procedure. A supine position increases the likelihood that the tube will enter the airway or that secretions will be inhaled. Choice D rationale The measurement for nasogastric tube insertion is from the tip of the nose to the earlobe and then to the xiphoid process, not the umbilicus. This traditional measurement method helps estimate the distance needed for the tube to reach the stomach. Measuring to the umbilicus would result in the tube being inserted too far, potentially causing it to coil in the stomach or enter the duodenum, which might not be the goal for basic gastric decompression.
