Phlebotomy第 61 / 100 题
Which vein is generally the preferred first choice for routine venipuncture in the antecubital area?
a.Median cubital vein
b.Basilic vein
c.Cephalic vein of the wrist
d.A vein on the underside of the wrist
解析
The median cubital vein is usually the first choice for venipuncture because it is large, well-anchored, and located away from major nerves and arteries. The cephalic vein is a second choice, and the basilic vein is used with caution due to its proximity to the brachial artery and nerves. Veins on the underside of the wrist are avoided due to injury risk.
