Which vein is NOT typically used for central venous access?

• A. Internal Jugular
• B. Subclavian
• C. Cephalic Vein
• D. Femoral

Answer: (C)

Central venous access aims to place a catheter into a large central vein that leads directly to the heart, providing reliable, high-flow access to the central circulation. The cephalic vein is a superficial, peripheral upper‑extremity vein that drains into the axillary/subclavian system, not a large central vessel. Its smaller size and peripheral location make it unsuitable for most central venous catheters, which is why it’s not used for central access. In contrast, veins like the internal jugular and subclavian provide direct, stable routes to the superior vena cava and right atrium, and the femoral vein is used when upper-body access isn’t possible. So the cephalic vein is not typically used for central venous access.
