What is a common risk associated with intravenous therapy via CVAD?

• A. Excessive fluid retention
• B. Thrombosis or clot formation
• C. Frequent blood transfusions
• D. Increased appetite

Answer: (B)

Thrombosis or clot formation is a common risk associated with intravenous therapy via a Central Venous Access Device (CVAD). This occurs because the presence of a catheter can lead to turbulence in blood flow and potential damage to the blood vessel lining, creating an environment conducive to clot formation. Factors such as decreased blood flow around the catheter, prolonged use of the device, and hypercoagulable states can further increase this risk.

The presence of a CVAD, particularly in larger veins, can increase the likelihood of thrombus development, which can lead to complications such as venous occlusion or pulmonary embolism. These serious complications require vigilant monitoring and management to ensure patient safety and effective therapy delivery. Understanding this risk is essential for healthcare providers who manage patients with CVADs, as it emphasizes the need for appropriate care protocols to prevent thrombotic events.
