The nurse is preparing to draw a blood sample. Which technique should the nurse implement when performing venipuncture?
a. Insert the needle, bevel up, at a 45-degree angle.
b. Select a vein that is rigid, cordlike, and prominent.
c. Insert the needle at once after scrubbing the skin with alcohol.
d. Pull the skin taut by placing the thumb about 2.5 cm (1 inch) below the site.
D
The nurse stabilizes the vein and minimizes rolling by pulling the vein with the thumb positioned about 1 inch below the insertion point to prevent contaminating the site. The needle is inserted at a 15- to 30-degree angle. The best vein to select will be prominent and straight with no signs of swelling or hematoma. The vein should rebound when palpated. The nurse allows the alcohol to dry before inserting the needle because the process kills microorganisms and the needle can carry alcohol into the puncture and increase the pain.
