A central venous catheter (CVC) is inserted into which type of vein?

• A. Inserted into a central vein (subclavian, internal jugular, or femoral)
• B. A peripheral vein in the arm
• C. An artery
• D. A capillary vein

Answer: (A)

Central venous catheters are placed into large veins that drain into the heart so meds and fluids can be delivered directly into the central circulation and, if needed, monitored from there. The typical sites are the subclavian vein, internal jugular vein, or the femoral vein, all considered central veins. Peripheral veins in the arm are smaller and used for short-term IV therapy, not for central access. Arteries carry blood away from the heart and are not suitable for venous catheters, and capillary veins aren’t practical access routes for this purpose. So, a CVC is inserted into a central vein like the subclavian, internal jugular, or femoral.
