Rationale of the Week | Teens’ A1C Climbs After Starting CGM

For last week’s practice question, we quizzed participants on SJ having questions about their insulin pen, and what would be the best response. % 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

Katie is a 14-year-old living with type 1 diabetes since age 10. She uses multiple daily insulin injections (MDI) therapy to manage her diabetes and started using a continuous glucose monitor (CGM) 3 months ago at the recommendation of her endocrinology team. Her A1c has increased to 9.2% since starting CCM technology.

Her mother reports that Katie has episodes of prolonged hyperglycemia when she is away from home. When at home, her mother will remind Katie to bolus based on the alerts she gets on the CGM share app. Katie reports she mutes alarms and alerts because she doesn’t want her classmates to hear them, afraid they will judge her. When you ask if she has uploaded her data to the school nurse or her endocrinology team she says, “The app is really confusing.” Her mother is frustrated with Katie for not paying attention to the CGM, saying, “She can text her friends without any problem; I don’t know why she struggles with the CGM”.

As the diabetes healthcare provider, how can you support Katie in improving her glycemic control?

  1. Turn on her CGM alarms but increase the high alarm so she doesn’t get as many hyperglycemia related alerts.
  2. Show her step-by-step how to use the app and how to troubleshoot the alerts and alarms.
  3. Have the school nurse monitor her CGM trends when Katie is at school, since her mom monitors the CGM trends when she is at home.
  4. Email Katie’s mother once a week for updates to make sure she is monitoring CGM trends.

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: % chose this answer, “Turn on her CGM alarms but increase the high alarm so she doesn’t get as many
hyperglycemia related alerts.” Helping Katie turn on and increasing her high alarm will not help
improve her glycemic control.

Answer B is correct: % chose this answer, “Show her step-by-step how to use the app and how to troubleshoot the alerts and alarms.” Guiding Katie through the CGM app and its functions helps her ask questions, resolve issues, and better monitor her glycemic control.

Answer C is incorrect: % chose this answer, “Have the school nurse monitor her CGM trends when Katie is at school, since her mom
monitors the CGM trends when she is at home.” Asking the school nurse to monitor CGM data while Katie is at school is not helping to improve Katie’s self-management skills.

Answer D is incorrect: % chose this answer, “Email Katie’s mother once a week for updates to make sure she is monitoring CGM
trends.” Emailing Katie’s mother does not help improve Katie’s CGM self-monitoring skills or her confidence level with the CGM app.

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!
