While flushing a central vascular access device, the nurse meets resistance. The nurse would:
1. Check the clamp on the catheter.
2. Manipulate the catheter.
3. Apply force to the syringe.
4. Discontinue the site.
Check the clamp on the catheter.
Rationale: The nurse would check the clamp on the catheter because the catheter is clamped when not in use; unclamping the catheter is necessary to initiate flushing of the catheter. Applying force to the syringe could result in damage to the catheter. Manipulating the catheter could result in misplacement of the catheter in the vena cava. Discontinuing the site would require a physician's order.
