When should you check the patency of a CVAD?

• A. Only after medication administration
• B. Before any infusion or blood draw
• C. At the patient's request
• D. Once every 24 hours

Answer: (B)

Checking the patency of a Central Venous Access Device (CVAD) is critical to ensure that the device is functioning properly and is free from obstruction. The most appropriate time to assess patency is before any infusion or blood draw. This is because establishing that the CVAD is patent helps to confirm that there are no clots or blockages that could interfere with medication delivery or blood sampling. Before initiating any treatment or procedure, it is essential to ensure that the vascular access is open and effective. This practice is vital for patient safety and helps to prevent complications such as infiltration, extravasation, or thrombus formation. Additionally, verifying patency prior to administering medications or drawing blood allows for a more reliable and efficient procedure. Other options may reflect situations where checking patency could be relevant, but they do not encompass the comprehensive safety protocol needed for effective CVAD management. For instance, checking at the patient’s request could lead to delayed responses in case of an actual problem, whereas infrequent checks every 24 hours might not adequately ensure the device's functionality on a day-to-day basis. Therefore, assessing patency before any infusion or blood draw is the most appropriate and medically sound practice.
