3
3. The phlebotomist uses the regional veins in the antecubital area for blood draws in the clinic because these veins are superficial, large, and well anchored; these charac-teristics increase the chances of a successful blood draw on the first puncture.
1. The antecubital area does not include the hand.
2. Except for punctures in the hand, venipunctures tend to cause the same degree of pain and bleeding regardless of the location.
4. The antecubital veins are superficial veins. The most distal veins in the arm are located in the hand and these veins are reserved for IV fluids.
