Final answer:
To address an occluded CVC during flushing with NS, reposition the patient's arm and then check for tubing kinks.
Step-by-step explanation:
If a central venous catheter (CVC) is occluded while trying to flush with 10 ml of normal saline (NS), the first thing to do is reposition the patient's arm. This involves gently moving the arm to ensure proper alignment of the catheter and the blood vessels. Once the arm is repositioned, check for tubing kinks by visually inspecting the entire length of the tubing for any bends or twists that might be causing the blockage.
