Question 13

The median cubital vein is the preferred vein for venipuncture on an adolescent patient.

The median cubital vein is typically the most accessible and largest vein in the antecubital fossa, making it the preferred choice for venipuncture in adolescents.

A) Cephalic

The cephalic vein is often more difficult to locate and may be positioned laterally, presenting a greater risk of complications during venipuncture. While it can be used, it is not the primary choice due to its variability and potential for difficulty.

B) Basilic

The basilic vein is located medially and is close to major arteries and nerves, which increases the risk of injury during venipuncture. Although it can be accessed, it is generally less favored compared to the median cubital vein due to these considerations.

C) Brachial

The brachial vein is deeper and less visible than the median cubital vein, making it harder to puncture effectively. Furthermore, it runs alongside the brachial artery, which poses a risk of arterial puncture, thus it is not recommended as the first option for venipuncture.

D) Median cubital

The median cubital vein is the most commonly used site for venipuncture due to its size, accessibility, and less risk of complications. It is centrally located in the antecubital fossa, providing a straightforward approach for blood collection, particularly in adolescent patients.

Conclusion

The median cubital vein is definitively the best choice for venipuncture in adolescents due to its accessibility and lower complication risk. Other options like the cephalic, basilic, and brachial veins either present challenges in locating or accessing them or carry higher risks, making them less suitable for this procedure.
