Answer

Blood glucose level – 201-225 mg/dL

  • If lower than the last blood glucose level by more than 30 mg/dL, increase rate by 2 U/h and bolus with 4 U intravenously.

  • If higher than the last blood glucose level by 0-30 mg/dL, increase rate by 1 U/h and bolus with 3 U intravenously.

  • If lower than the last blood glucose level by 1-20, increase rate by 1 U/h and bolus with 2 U intravenously.

  • If lower than the last blood glucose level by 21-50 mg/dL, remain at the same rate.

  • If lower than the last blood glucose level by 51-80 mg/dL, decrease rate by half (50%) and recheck blood glucose levels in 30 minutes.

  • If lower than the last blood glucose level by more than 80 mg/dL: Stop drip and recheck blood glucose level in 30 minutes . If the infusion is turned off, recheck the blood glucose level in 30 minutes; when BG is more than 175 mg/dL, restart at 50% of previous rate.

  • Recheck blood glucose levels in 30 minutes. Repeat every 30 minutes until less than 200 mg/dL.
