Answer

Blood glucose level - 101-124 mg/dL

  • If greater than the last test result, decrease rate by 0.3 U/h.

  • If lower than the last test result, stop drip and recheck blood glucose in 30 minutes. If the infusion is turned off, recheck blood glucose in 30 minutes. When blood glucose is more than 125 mg/dL, restart at 50% of previous rate and recheck the blood glucose level in 30 minutes.

  • If lower than last result by 15-30 mg/dL, decrease the rate by half (50%) and recheck blood glucose in 30 minutes.

o If equal to the last result or lower than the last result by less than 7 mg/dL, decrease the rate by 0.3 U/h.

  • Recheck the blood glucose every 30 minutes until more than 100 mg/dL.
