An LPN is preparing to administer medication to a client via a nasogastric (NG) tube. After checking the tube placement, the LPN notes resistance when attempting to flush the tube with water. What is the most appropriate initial action?

  1. ANotify the registered nurse (RN) or physician immediately.
  2. BApply forceful pressure to the syringe to clear the obstruction.
  3. CReposition the client and attempt to flush the tube again gently.
  4. DInstill a small amount of carbonated beverage into the tube.
Show answer & explanation

Correct answer: C. Reposition the client and attempt to flush the tube again gently.

Resistance during flushing suggests a potential obstruction. Repositioning the client (e.g., turning from side to side) can sometimes dislodge the obstruction. Attempting to flush gently again after repositioning is a safe and appropriate initial step before escalating to more invasive or risky interventions.

Why the other options are wrong

  • A. While the RN or physician may need to be notified eventually, less invasive measures should be attempted first.
  • B. Forceful pressure can cause tube perforation or push the obstruction further into the tube.
  • D. Carbonated beverages are not recommended for clearing NG tube obstructions as they are ineffective and can introduce air into the stomach.

NG Tube Obstruction

A blockage within a nasogastric tube that prevents fluid or medication from passing through.

  • Common causes include crushed medication residue, formula, or tube kinking.
  • Initial interventions focus on gentle methods like repositioning and gentle flushing.
  • Forceful flushing or unapproved solutions should be avoided to prevent complications.

Memory trick: NG Tube Stuck? Reposition, Then Gently Chuck!
