How does hydration impact the function of a CVAD?

• A. It decreases the catheter's length
• B. It improves patency and reduces clot risks
• C. It causes increased pressure in the line
• D. It makes aspiration more difficult

Answer: (B)

Hydration plays a crucial role in the function of a central venous access device (CVAD) primarily by improving patency and reducing the risks of clot formation. When a patient is well-hydrated, their blood volume is optimized, which leads to improved blood flow and better circulation around the CVAD. This increased blood flow helps to keep the lumen of the catheter clear and reduces the likelihood of clotting within the catheter. Hydration affects the viscosity of the blood; adequately hydrated individuals have less viscous (thinner) blood. This thinner blood can flow more easily through the CVAD, helping to maintain access and functionality. Ensuring proper hydration is essential for patients with a CVAD as it minimizes complications such as occlusions and enhances the overall efficacy of the device. Regarding other options, the catheter's length is not affected by hydration, pressure in the line typically relates to flow dynamics and resistance rather than hydration status, and aspiration is generally more effective with better hydration levels that promote blood flow rather than making it difficult. Therefore, the impact of hydration on CVAD functionality is significant and aligns with its beneficial effects on patency and reduced clot risks.
