Answer

Blood glucose level – 226-250 mg/dL

  • If lower than the last blood glucose level by more than 80 mg/dL, decrease rate by half (50%).

  • If lower than the last blood glucose level by 30 –80 mg/dL, continue same rate.

  • If lower than the last blood glucose level by 0-30 mg/dL, increase the insulin rate by 1 U/h and bolus with 2 intravenous units.

  • If higher than the last blood glucose level by 1-20 mg/dL, increase the insulin rate by 2 U/h and bolus with 4 intravenous units.

  • If higher than the last blood glucose level by more than 20 mg/dL, increase the insulin rate by 3 U/h and bolus 6 intravenous units; recheck blood glucose level in 30 minutes.

  • Repeat blood glucose testing every 30 minutes until less than 200 mg/dL.
