    A nurse is preparing to perform a blood glucose test. After performing hand hygiene and donning gloves, in which order should the nurse perform the following actions to obtain a capillary blood sample? (Move the steps into the box on the right, placing them in the order of performance. Use all the steps.)

    Explanation & Rationale

    A. Pierce the puncture site quickly: The puncture is performed after proper site preparation and drying to minimize pain and reduce the risk of contamination. A quick puncture ensures adequate blood flow and less tissue trauma. B. Allow the site to dry: After cleansing the site with an antiseptic swab, allowing it to air dry prevents alcohol or antiseptic residue from contaminating the blood sample. Residual moisture can interfere with test accuracy and cause stinging. C. Cleanse the site with an antiseptic swab: Proper cleansing reduces the risk of infection at the puncture site. The site should be wiped using a circular motion and then allowed to dry completely before puncturing. D. Apply blood to the test strip: Once a sufficient blood droplet is obtained, it is applied directly to the glucose test strip for accurate measurement. Proper application ensures the meter reads the correct glucose concentration. E. Squeeze the site gently to obtain a blood droplet: Gentle pressure helps produce an adequate blood droplet without causing tissue trauma or hemolysis. Excessive squeezing can dilute the sample with interstitial fluid, affecting accuracy.
