Quizplus · Accepted Answer

The left forearm (median cubital vein) is generally the best choice for blood withdrawal in this situation due to the presence of an IV in the basilic vein of the right forearm. Using the right forearm could result in contaminating the blood sample with fluids from the IV. The left upper arm (brachial vein) may be used as well, but the median cubital vein is typically easier to locate and access. The foot (greater saphenous vein) is not a preferred site for blood withdrawal unless there are no other options available.
