@BlogLove – Another site that blood can be drawn from is the back of the hand. If an IV needs to be placed, depending on the size of the line it can be placed in the neck or upper chest, or in the leg. Central IV lines are used when multiple drugs need to be administered – these can be placed in the neck and upper chest. The veins in the leg can also be used sometimes. The vein in the leg that are typically used for placement of a central line is the femoral vein, which is located near at the top of the leg near the groin area.
