Quizplus · Accepted Answer

The median cubital vein is generally the easiest and most accessible vein for venipuncture. It is located in the antecubital fossa (the bend of the arm), and is typically larger and more superficial than other veins in the area. The ulnar and radial veins are smaller and deeper, while the brachial vein is larger and deeper, making them more difficult to access. The cephalic vein is also a viable option but can be more difficult to find and may require more manipulation of the arm.
