Question: 1 / 400

After drawing blood from a CVAD, what should the nurse do to maintain proper functioning of the device?

Flush the catheter with alcohol

Flush the catheter with preservative-free 0.9% sodium chloride

Flushing a central venous access device (CVAD) with preservative-free 0.9% sodium chloride is essential for maintaining proper functioning of the device. This saline solution is isotonic, which helps to keep the catheter patent by ensuring that any blood or debris does not coagulate and block the catheter. Additionally, using preservative-free saline is crucial because preservatives can cause irritation or adverse reactions within the bloodstream. Regular flushing after drawing blood clears the catheter of any residual blood and keeps it patent for future use, which is crucial for preventing complications such as thrombosis or catheter occlusion.

This practice not only preserves the integrity of the device but also ensures safe and effective patient care. Proper flushing technique is a critical component of catheter maintenance protocols that all healthcare providers must follow.
