5)Sheath/Sleeve-rubber piece covering the second needle(that punctures the tube stopper) which can bounce back to cover the tip, stopping the flow of blood, therefore allowing multiple tubes to be drawn from a single stick 6)Hub/Tube Holder-a plastic sleeve that the needle hilt screws into, which also serves as a tube holder 7)Safety Device-designed to be engaged immediately after withdrawing the needle from the patient to prevent accidental needlesticks and possible exposure to bloodborne pathogens Name four areas to avoid during the venipuncture procedure - correct answer 1)hematomas-blood that has pooled and clotted in the tissue above the vein (the old blood gets into the lumen and then into the evacuated tube, causing inaccurate results) 2)scar tissue- dense collagenous fibers in the connective tissue, from previous injuries, that are very hard to penetrate with a needle
