Irrigate the tube with cola.-the nurse should irrigate the tube with cola because its effervescence and acidity are suited to the purpose, its inexpensive, and its readily available in most homes. advancing the ng tube is inappropriate because the tube is designed to stay in the stomach and isnt long enough to reach the intestines. applying intermittent suction or using a syringe for aspiration is unlikely to dislodge the material clogging the tube but may create excess pressure. intermittent suction may even collapse the tube.
