Final answer:
For venipuncture, the best practice is to choose the most superficial vein in the antecubital fossa, as these are easier to access and cause less discomfort. The median cubital vein is often selected due to its superficial location and visibility.
Step-by-step explanation:
Venipuncture: Vein Selection in the Antecubital Fossa
When performing a venipuncture, the selection of a vein in the antecubital fossa must be done carefully. The most common site for drawing venous blood is the median cubital vein, which is a superficial vein that links the cephalic vein to the basilic vein. It is recommended practice to select a vein that is both visible and superficial, as these are less painful for the patient and easier to access. Among the visible veins, healthcare providers often look for the largest suitable vein to ensure an adequate flow during the blood draw.
The correct answer to the order of vein selection in the antecubital fossa for venipuncture is: c) The most superficial vein. Superficial veins like the median cubital vein are more prominent and easier to puncture. Deeper veins are not typically the first choice for venipuncture due to increased difficulty and higher risk of complications.
