Which vein is commonly used for venipuncture?

• A. Cephalic vein
• B. Basilic vein
• C. Median antecubital vein
• D. Median cubital vein

Answer: (D)

The vein in the cubital fossa that is most commonly used for venipuncture is the median cubital vein. This vein sits just beneath the skin in the elbow crease, usually large and easy to feel, and lies relatively still when you palpate it. Its typical position between the cephalic (lateral) vein and the basilic (medial) vein makes it a stable target with a straightforward path for the needle, which reduces the chance of missing or hitting deeper structures.

Veins like the cephalic are on the outer side of the arm and can roll or be harder to access, while the basilic vein is closer to the inner arm and can be deeper and nearer to nerves and arteries, making venipuncture trickier and riskier in some patients. The median antecubital vein is not the standard term used for this preferred site, and the median cubital vein remains the go-to choice for its reliability and ease of access.
