A nurse positions a patient for the insertion of a nasogastric (NGT) tube by:

Choice A rationaleThe side-lying position with the head of bed at 30 degrees does not optimally align the nasal passages with the esophagus, increasing the risk of the NGT entering the trachea. Proper alignment facilitates easier and safer insertion into the stomach.Choice B rationaleThe tripod position is typically used for patients experiencing respiratory distress to maximize lung expansion. It does not provide the necessary head and neck alignment for safe nasogastric tube insertion.Choice C rationaleSitting the patient in an upright position, ideally between 45 to 90 degrees, uses gravity to aid the passage of the NGT down the esophagus. This position also allows the patient to cough effectively if the tube inadvertently enters the trachea.Choice D rationaleHyperextending the patient's head during NGT insertion can close off the esophagus and open the trachea, significantly increasing the risk of misplacement of the tube into the respiratory tract. The neck should be flexed forward with the chin to the chest during insertion.
