    Which site should you avoid for venipuncture?

    Do not use the tip of the finger or the center of the finger. Avoid the side of the finger where there is less soft tissue, where vessels and nerves are located, and where the bone is closer to the surface. The 2nd (index) finger tends to have thicker, callused skin.

    Why should you not use the basilic vein?

    The basilic vein is close to the brachial artery so there is more risk of hitting an artery. Exercise caution when drawing from this area. Additionally, this area is often more sensitive, thus a stick is slightly more painful for the patient.
