Which of the following is NOT a common site for venipuncture?

The femoral vein is not a common site for venipuncture primarily due to its location and the associated risks. The femoral vein is situated deeper in the body and is surrounded by vital structures, including major arteries and nerves, making venipuncture at this site more challenging and potentially dangerous.

In contrast, the median cubital vein, basilic vein, and cubital vein are located in the upper arm and are more accessible, which significantly reduces the risk of complications during the blood collection process. These veins are well-defined and have a good size for drawing blood, making them the preferred sites for venipuncture in most routine procedures. The use of these more accessible veins minimizes potential damage to surrounding tissues and arteries, ensuring a safer and simpler process for both the patient and the healthcare professional.
