A practical nurse is preparing to perform a routine capillary blood glucose test for a client with diabetes mellitus. In what order should the nurse perform the following actions to obtain an accurate sample and minimize complications? Arrange the steps from first to last.
- 1Clean the selected puncture site with an alcohol swab.
- 2Allow the alcohol on the skin to dry completely.
- 3Puncture the lateral aspect of the fingertip using a sterile lancet.
- 4Wipe away the first drop of blood using a dry, sterile gauze pad.
- 5Apply the second drop of blood directly to the reagent test strip.
Answer
The correct sequence is to first clean the site with alcohol, allow it to dry completely, puncture the side of the finger, wipe away the initial drop of blood, and then apply the second drop to the test strip.
To obtain an accurate capillary blood glucose reading and reduce the risk of potential complications, the practical nurse must follow a strict procedural sequence. First, the site is cleaned to prevent infection. Second, the alcohol must dry completely to prevent it from altering the glucose reading. Third, the puncture is made on the less sensitive side of the finger. Fourth, the first drop of blood is wiped away because it contains tissue fluid that dilutes the sample. Finally, the second drop of pure capillary blood is applied to the test strip for an accurate measurement.
