NHA Phlebotomy Certification Practice Exam

Which vein is typically the vein of choice for routine venipuncture?

1. Median cubital

2. Radial

3. Cephalic

4. Basilic

The correct answer is: Median cubital

The median cubital vein is favored for routine venipuncture due to its accessibility and stability. This vein is located in the antecubital fossa, which is the crease of the elbow, making it easily palpable for phlebotomists. It is generally larger than other veins and has a more straightforward course, reducing the likelihood of complications during the puncture. Additionally, the median cubital vein is centrally positioned between the cephalic and basilic veins and is not typically accompanied by major nerves or arteries, which minimizes the risk of injury during the procedure. Its desirable characteristics make it the first choice for drawing blood samples, especially in a laboratory setting where multiple blood collections may be needed. In contrast, the other veins listed may have limitations. The cephalic vein, while also accessible, is often more difficult to puncture and may be more variable in its position. The basilic vein, though suitable, is located closer to important structures, such as nerves and arteries, which increases the risk of complications. The radial vein, found in the wrist, is generally not used for venipuncture due to its smaller size and difficulty of access.
