The Vein in the Arm Commonly Sampled for Blood by Venipuncture

Question

The vein in the arm commonly sampled for blood by venipuncture is the ________ vein.
A) cephalic
B) basilic
C) brachial
D) median cubital
E) ulnar

Accepted Answer

The median cubital vein is the most commonly used vein for venipuncture as it is easily accessible, usually large and runs parallel to the skin surface, making it easy to locate. The cephalic and basilic veins can also be used, but they are more difficult to locate and can be smaller in some individuals. The brachial and ulnar veins are not commonly used for routine blood draws.
