In advancing the NG tube, which technique provides the safest outcome?
a. Rotate the tube if resistance is felt.
b. Advance the tube in between swallows.
c. Start with the patient's head flexed.
d. Check the tube placement by instilling air and auscultating over the stomach.
A
If resistance is met, try to rotate the tube and see whether it advances. If there is still resistance, withdraw the tube, allow the patient to rest, relubricate the tube, and insert it into the other naris. Advance the tube 2.5 to 5 cm (1 to 2 inches) with each swallow of water. If the patient is not allowed fluids, instruct him to dry swallow or suck air through a straw. Initially, instruct the patient to extend his neck back against the pillow; insert the tube slowly through the naris with the curved end pointing downward. Verify tube placement. Check agency policy for preferred methods.
