Practice question from Insulin Dosing & Titration

An adult patient with type 2 diabetes is receiving insulin glargine 30 units once daily. Over the past 3 consecutive mornings, the patient’s fasting blood glucose has averaged 165 mg/dL. The target fasting glucose range is 80–130 mg/dL. Using a standard treat-to-target basal insulin titration protocol, what is the most appropriate adjustment? A. Increase by 2 units B. Increase by 4 units C. Increase by 6 units D. Increase by 8 units E. No change needed

Answer

C

Explanation

Fasting glucose 140-179 mg/dL warrants an increase of 6 units according to the treat-to-target titration protocol. This systematic approach safely optimizes basal insulin while minimizing hypoglycemia risk.
