Administer insulin according to the patients sliding scale orders.

Note: Regular exercise plays an important role in glycemic control, but it will not lower blood glucose level in a timely manner. In fact, when diabetes is uncontrolled, exercise can actually raise blood glucose levels and cause ketonuria. Note: Unless there is a reason to believe that the glucometer used is inaccurate or has not been calibrated or there is a problem with the test strips, it is unnecessary to repeat the test. Note: The patient's blood sugar is elevated. There is no indication to give a glucose source at this time.

Rub the patient's arm at the selected site prior to venipuncture. Stroking the arm from the distal area to the proximal area below the proposed site can help dilate the vein, but vigorous rubbing should be avoided due to the potential for injury. Note: The tourniquet should be released after vein selection to restore circulation while the site is prepped. Note: It is recommended that the extremity be in a dependent position to help dilate the vein and make it more visible.

Wrap the finger in a warm cloth. Heat helps increase blood flow to the area to be punctured. Note: Dangling the hand is recommended to promote blood flow to the fingers. The nurse should pierce the lateral aspect of the finger. Piercing it in the middle is more painful for the client and is unlikely to affect blood flow. Milking the puncture site to get a full blood sample is not recommended as it could lyse, or break, the blood cells and alter the test results. Gentle squeezing is permissible.
