Rationale of the Week | Gestational Diabetes: Diabetes Care in the Fourth Trimester

For last week’s practice question, we quizzed participants on Gestational Diabetes: Diabetes Care in the Fourth Trimester. 51% of respondents chose the best answer. We want to clarify and share this important information, so you can pass it on to people living with diabetes and your colleagues, plus prepare for exam success!

Before we start though, if you don’t want any spoilers and haven’t tried the question yet, you can answer it below: Answer Question

Lightbulb and text: Rationale of the Week

MT is a 29-year-old with Type 1 diabetes who is currently 14 weeks pregnant. She uses a continuous glucose monitor (CGM) with concurrent fingersticks and uploads her glucose data weekly. Her CGM settings was already set to the recommended time in
range and the latest CGM report shows the following: time in range (TIR): 67%, time below range: 6%, time above range: 27%.

Based on current ADA Standard of Care, which of the following statements is most accurate regarding her CGM values?

  1. The recommended time in range is >70% within 70–180 mg/dL. MT’s TIR is slightly below target and her time below range is above the recommended targets, indicating adjustments are needed to reduce hypoglycemia.
  2. The recommended time in range is >70% within 63–140 mg/dL; MT’s TIR is slightly below target and her time below and above range is above the recommended goal.
  3. The recommended time in range is >80% within 63–140 mg/dL; MT’s TIR is below target, with fluctuations of hypo and hyperglycemia.
  4. The recommended time in range is >80% within 70–180 mg/dL to prevent fetal complications; MT’s TIR is significantly below the recommended Standard of Care target.

Getting to the Best Answer

If you are thinking about taking the certification exam, this practice test question will set you up for success. Test writers anticipate possible answers based on the details in the question. They will wave those “juicy answers” right under your nose. Your job is to weed through the particulars, pluck out the most important elements and choose the BEST answer.

Answer A is incorrect: 16.58% chose this answer, “The recommended time in range is >70% within 70–180 mg/dL. MT’s TIR is slightly below target and her time below range is above the recommended targets, indicating adjustments are needed to reduce hypoglycemia.” Answer A is incorrect. The answer uses non-pregnancy CGM target range of 70–180 mg/dL. Pregnancy target range for individuals with type 1 diabetes are lower, keep reading for the best answer.

Answer B is correct: 51% chose this answer, “The recommended time in range is >70% within 63–140 mg/dL; MT’s TIR is slightly below target and her time below and above range is above the recommended goal.” Answer B is correct. Based on the 2025 ADA Standards of Care the recommended time in range targets for individuals with type 1 diabetes during pregnancy is >70% between 63-140 mg/dL, < 4% under 63 mg/dL with < 1 % under 54 mg/dL, and < 25% over 140 mg/dL.

Answer C is incorrect: 19.55% chose this answer, “The recommended time in range is >80% within 63–140 mg/dL; MT’s TIR is below target, with fluctuations of hypo and hyperglycemia.” Answer C is incorrect. The time in range target is above the evidenced-based
minimum and MT is having frequent hypoglycemia in addition to hyperglycemia, both outside the goal ranges.

Answer D is incorrect: 12.87% chose this answer, “The recommended time in range is >80% within 70–180 mg/dL to prevent fetal
complications; MT’s TIR is significantly below the recommended Standard of Care target.” Answer D is incorrect. The recommended target range for individuals with type 1diabetes during pregnancy is 63-140 mg/dL as stated above.

We hope you appreciate this week’s rationale! Thank you so much for taking the time to answer our Question of the Week and participate in this fun learning activity!
