What should be done if resistance is felt while flushing a CVAD?

• A. Continue flushing with more force
• B. Stop the flush and assess for obstruction
• C. Report to a supervisor immediately
• D. Use a different catheter

Answer: (B)

When resistance is felt while flushing a Central Venous Access Device (CVAD), it is essential to stop the flush and assess for obstruction. This action is correct as it prioritizes patient safety and minimizes potential complications. Flushing with more force can cause damage to the catheter or the surrounding vasculature, which may lead to catheter fracture or displacement. Additionally, if there is an obstruction, forcing fluid through the device may worsen the situation, potentially leading to embolism or other serious issues.

Assessing for obstruction involves a careful evaluation of the catheter's patency, checking for issues like thrombosis, kinking, or infiltration. It is crucial to determine the cause of the resistance before attempting any further intervention, ensuring that the health of the patient is maintained and complications are avoided.
