What is a common risk associated with CVADs?

• A. Excessive hydration
• B. Skin irritation at the insertion site
• C. Pneumothorax from CVAD placement
• D. Limited mobility due to device

Answer: (C)

A common risk associated with Central Venous Access Devices (CVADs) is pneumothorax from CVAD placement. This occurs because CVADs are often inserted into large veins in the neck, chest, or groin, and the insertion process involves puncturing the skin and underlying tissues to access the vein. If the needle inadvertently punctures the pleura, which is the membrane surrounding the lungs, air can enter the pleural space, leading to a pneumothorax. This is a serious complication as it can cause shortness of breath, chest pain, and may require immediate medical intervention.

While other risks are associated with CVADs, such as skin irritation at the insertion site or limited mobility due to the device, pneumothorax specifically relates to the technical aspect of placement and poses an acute threat that necessitates awareness during the procedure. Proper technique and monitoring during and after insertion can help minimize this risk, emphasizing the importance of trained personnel performing such procedures.
