Answer

Blood glucose level - 70-100 mg/dL

  • If previous blood glucose level is more than 120 mg/dL or if symptomatic from hypoglycemia and the patient is not receiving anything orally, give 15 mL of D50W intravenously; if the patient is able, administer 4-6 oz of juice or 3 glucose tablets orally.

  • Recheck blood glucose levels ever 30 minutes until it is more than 100 mg/dL.

  • If the next blood glucose measurement is 70-99 mg/dL, repeat previous treatment.

  • When the blood glucose level is more than 125 mg/dL, restart the insulin rate at 50% of the previous rate and recheck the blood glucose level in 30 minutes.
