How frequently should CVAD patency be assessed?

• A. Once a day
• B. At least once per shift when in use
• C. Only when patient requests
• D. After every infusion

Answer: (B)

Assessing the patency of a Central Venous Access Device (CVAD) at least once per shift when it is in use is crucial for ensuring optimal patient care and minimizing complications. Frequent assessments help to verify that the device remains open and functional, which is essential for effective medication delivery, fluid administration, and blood sampling.

By performing this check at least once per shift while the CVAD is in use, healthcare providers can promptly identify any issues such as occlusion or thrombosis. This proactive approach helps in addressing potential problems before they affect patient treatment. Furthermore, regular assessment aligns with best practices in maintaining the integrity of the vascular access device, thus supporting patient safety and comfort.

The other choices suggest less frequent or situational checks, which could lead to undetected problems and increased risk of complications. Regular assessments not only enhance the reliability of the CVAD but also contribute to overall patient outcomes.
