9 Assemble Holder & Needle Put short end of needle into threaded hole in vacutainer holder Screw tightly using clockwise motion

10 Insert the Tube into the Holder Insert stoppered end of the tube into holder Do not push tube beyond the guideline Inspect the needle for barbs, corrosion

11 Identify Patient Explain the procedure and purpose Ask patient about allergies (i.e., iodine or alcohol). Position the patient - sitting or lying Never draw blood from a standing patient. Position protective pad

12 Apply Constricting Band Apply with enough pressure to stop venous return A radial pulse should be felt Place latex tubing around limb about 2 inches above venipuncture site If a commercial band is used, wrap it around limb and secure by overlapping velcro ends

13 Instruct patient to clench and unclench his fist several times to trap blood and distend veins Avoid veins that are infected, injured, irritated, or have an IV running distally. Apply Constricting Band

14 Palpate Selected Vein Palpate along length of vein with index finger Vein should have a spongy feel Clean the skin Do not re-palpate the vein after cleansing the skin.

15 Prepare the Puncture Site Cleanse area with betadine or alcohol using a circular motion Do not touch the area once cleansed

16 Prepare to Puncture the Vein Remove protective cover from needle Position needle in line with vein and grasp patient's arm below entry point with free hand Place thumb of free hand 1 inch below entry site and pull skin taut toward hand

17 Puncture the Vein Align needle bevel up Pierce skin at a 15° to 30 ° angle Decrease angle until parallel to skin surface, then pierce vein If needle is withdrawn above skin surface, do not attempt venipuncture again with the same needle 15 ° to 30 °

18 If unsuccessful –Release the constricting band –Place 2 x 2 gauze sponge over site –Quickly withdraw the needle and instruct the patient to elevate arm slightly and keeping the arm fully extended apply pressure to the site for 2 to 3 minutes. –Notify supervisor before attempting another venipuncture Puncture Vein

19 Single Tube Collections When the tube is nearly full release the tourniquet Remove the tube from the holder DO NOT withdraw the needle before the constricting band is released
