9. Determine the patient’s preferred site for the procedure
based on his or her previous experience. Expose the arm,
supporting it in an extended position on a firm surface,
such as a tabletop. Position self on the same side of the
patient as the site selected. Apply a tourniquet to the upper
arm on the chosen side approximately 3 to 4 inches above
the potential puncture site. Apply sufficient pressure to
impede venous circulation, but not arterial blood flow.
10. Put on unsterile gloves. Assess the veins using inspection
and palpation to determine the best puncture site.
