A CVC is occluded while flushing with 10 mL NS. What is the first action?

• A. Reposition the patient's arm and check for tubing kinks
• B. Increase the flush volume
• C. Notify the provider immediately
• D. Clamp the catheter and attempt to flush again

Answer: (A)

When a central venous catheter becomes occluded during flushing, treat the problem as a mechanical issue first. The most likely culprit is something simple you can fix right away, such as external compression, a kink, or a poorly positioned arm that interferes with the catheter’s path. Repositioning the patient’s arm and checking the tubing for kinks directly addresses these common causes and often restores patency without more invasive steps. If the flow improves after adjusting position and removing any kinks, you can resume flushing and continue to monitor. If the occlusion persists despite these mechanical checks, then other factors like a clot or catheter malposition need to be explored and the provider may need to be notified per protocol. Avoid increasing the flush volume initially, as that does not fix a mechanical obstruction and could cause harm. Clamping and retrying can worsen occlusion and raise the risk of complications such as air embolism. Notifying the provider is important if simple mechanical adjustments don’t resolve the issue or if there are additional concerns, but it isn’t the first step.
