Reduction of Risk PotentialQuestion 1877 of 2368

A central line will not infuse, and no blood return is obtained. Which initial action should the nurse take?

  1. Flush the line forcefully with a small syringe to clear the occlusion
  2. Remove the central line immediately and notify the provider afterward
  3. Increase the infusion pump pressure to push through the resistance
  4. Reposition the client, then have them raise the arm overhead or cough
Show answer

Correct answer: Reposition the client, then have them raise the arm overhead or cough

Occlusion may be due to a clot or malposition, so repositioning is tried first. Flushing against resistance can rupture the catheter.
