Initials Corresponding Signature of Instructor Title Supplies needed: Disposable exam gloves 2 x 2 gauze pads Alcohol or povidone-iodine sponges Tourniquet Puncture-resistant needle disposal container Syringe method: 10-mL syringe Sterile needles: gauge for adults, or 23-gauge butterfly Vacuum-tube method: Vacuum tube with needle holder Sterile double-needles: gauge for adults, gauge for children Plastic bag for used supplies Adhesive bandage Procedure Guidelines S/U Initials S/U Initials 1. Perform your beginning procedure 2. Apply a tourniquet and locate a vein. Select the largest, most stable vein in the area. When palpated, the site will feel firm and rebound slightly. 3. Release the tourniquet.

3 Procedure Guidelines S/U Initials S/U Initials 4. Cleanse the site with alcohol. Wipe in a circular motion. Begin in the center of the venipuncture site and extend the circle out 2 inches in diameter. 5. Allow the alcohol or other skin prep to dry thoroughly. 6. Reapply the tourniquet, taking care not to bump or touch the prepped skin area. 7. Remove the needle cover, holding the needle bevel facing up in your dominant hand. 8. Stabilize the vein by holding it with your nondominant thumb, approximately 1 inch below the puncture site. Warn the patient that he or she will feel a stick. 9. With the needle at a 15-degree angle, slowly enter the patient s vein. You will feel a change of pressure when it enters the vein. Slowly advance the needle 1 4 inch. 10. Release the tourniquet by pulling the upper end downward, before removing the needle. If you are releasing the tourniquet while filling tubes, hold the collection device securely. Avoid pulling upward, as this may cause the needle to come out of the patient s arm. 11. Continue the procedure by obtaining the blood specimen with the syringe or vacuum method or starting the intravenous infusion. 12. Place a 2 x 2 gauze pad over the insertion site. Avoid using cotton balls. Cotton balls tend to stick to the venipuncture site and, when removed, remove the platelet plug, causing bleeding. 13. Quickly withdraw the needle. Immediately apply pressure on the insertion site. Maintain the pressure for 2 to 3 minutes, or longer, until bleeding stops. 14. Cover the puncture site with an adhesive bandage.

18 Procedure Guidelines S/U Initials S/U Initials 5. Hold the plastic end of the lancet in your dominant hand. With your nondominant hand, break the plastic cover off the end to expose the needle. 6. Hold the lancet at a 45-degree angle. With the sharp end of the lancet, pierce the skin. For an adult fingerstick, make the stick perpendicular to the lines in the fingerprints. Follow the directions for the type of lancet you are using. If the lancet has a plunger, depress it to pierce the skin while holding pressure on the site. 7. Remove the lancet. Discard it in the puncture-resistant sharps container. 8. Wipe the first drop of blood away with a sterile 2 x 2 sponge. You will need the rest to fill the containers. 9. Hold the collection tube near the puncture site. Position the tube almost horizontally, with the end slightly down. Squeeze the skin slightly, allowing blood to flow into the tube. Do not squeeze hard, as this forces tissue fluid into the sample, diluting it. If blood does not flow freely, create suction by placing your gloved finger over the end of the capillary tube, or by squeezing the small bulb. Fill the tube approximately 2 3 to 3 4 full. Usually, two or three tubes are filled. 10. Apply gentle pressure with the 2 x 2 gauze to the skin to prevent painful bleeding inside the tissues. The patient can hold the gauze sponge in place until the bleeding stops. Avoid using cotton balls. Cotton balls tend to stick to the puncture site and, when removed, remove the platelet plug, causing bleeding. 11. Wipe any remaining blood from the skin, and cover with an adhesive bandage. 12. Label the sample while in the patient s room. 13. Perform your procedure completion

Perform your beginning procedure Double-check the requisition slip. 2. Support the patient s arm on the bed or other surface, palm up. Make sure the patient is comfortable and can maintain this position for the duration of the procedure. 3. Apply the blood pressure cuff to the upper arm. Do not inflate it. 4. Apply gloves.

21 Procedure Guidelines S/U Initials S/U Initials 5. You will perform the test approximately 4 inches below the antecubital space. Cleanse the site with alcohol or povidone-iodine. Wipe in a circular motion. Begin in the center of the puncture site and extend the circle out 3 inches in diameter. 6. Allow the alcohol or other skin prep to dry. 7. Remove the Surgicutt, template, or other product from the package. Twist off the tab on the side, taking care not to touch the blade or activate the trigger. 8. Inflate the blood pressure cuff until the gauge reads 40mm Hg. You must start the test within 60 seconds of inflating the cuff. 9. Apply the Surgicutt or other device to the prepared skin, approximately 4 inches below the antecubital space. Position the device so the blade is parallel to the bend in the elbow. 10. Depress the trigger while monitoring the second hand on your watch. Remove the blade from the skin within 1 second of depressing the trigger. Record the time. Discard the device containing the blade in the puncture-resistant container. 11. Absorb the blood with the edge of the filter paper. Position the paper near the incision, without touching the wound directly. Placing the paper directly on the incision will interfere with the results of the test. 12. With the filter paper, blot the bleeding every 30 seconds. When the blood no longer stains the paper, stop timing. Discard the filter paper in the plastic bag. Record the time the test ended. 13. Deflate the blood pressure cuff. 14. Wipe remaining blood from the skin. 15. Apply a steri-strip, butterfly bandage, or dressing to the incision. 16. Remove the gloves and discard in the plastic bag.
