4. To prevent tissue trauma and minimize client discomfort during NGT insertion, the nurse assesses the patency of both nares before insertion. This helps the nurse deter-mine which nares are more patent and the best nares to use for the initial attempt.
1. If the prescription calls for an NGT, a soft pliable gastric tube is an unsuitable substitute because a soft tube does not allow aspiration of gastric contents.
2. If the nares are obstructed, additional lubricant cannot overcome the obstruction and can cause significant client trauma if the nurse attempts an insertion.
3. The nurse avoids instructing the client to bear down during NGT insertion because the Valsalva maneuver engorges tissue and is more likely to impair passage of the NGT.
