Which vein is described as the phlebotomy vein of choice because it is large and does not tend to move when the needle is inserted?

• A. Median Vein
• B. Cephalic Vein
• C. Basilic Vein
• D. Median Cubital Vein

Answer: (D)

The median cubital vein in the antecubital fossa is the vein of choice because it sits directly under the skin, is typically large, and remains relatively still when the needle is inserted. Its size makes it easier to see and palpate, and its position between the cephalic (lateral) and basilic (medial) veins tends to be stable, so it doesn’t roll as much as other surface veins. This combination—ample size, superficial location, and minimal movement—gives the most reliable, straightforward access for drawing blood. If this vein isn’t usable, clinicians turn to other superficial veins, which are more likely to roll or be smaller and harder to access.
