A practical nurse is preparing to perform a capillary blood glucose test for an adult client with diabetes mellitus. To ensure an accurate result and reduce the risk of complications, in which order should the nurse perform the following steps? Arrange the actions in the correct chronological sequence.
- 1Perform hand hygiene and put on clean gloves.
- 2Cleanse the lateral aspect of the finger with an alcohol swab and allow it to air dry.
- 3Puncture the side of the fingertip using a sterile lancet.
- 4Wipe away the first drop of blood using a clean gauze pad.
- 5Apply the next drop of blood to the reagent test strip.
Answer
The correct sequence is: perform hand hygiene and don gloves, cleanse the site and let it air dry, puncture the finger, wipe away the first drop of blood, and finally apply the second drop of blood to the test strip.
Following the correct chronological sequence ensures that standard precautions are maintained, the site is properly prepped without alcohol interference, and the specimen is undiluted by tissue fluid. This methodical approach directly reduces the risk of inaccurate laboratory results and subsequent incorrect insulin administration.
