Diabetes Education Certification Diabetes Technology & Devices 1 — Questions and Answers
Question 1: What does CGM stand for in diabetes management technology?
- Continuous Glucose Monitor (Correct answer)
- Calibrated Glucose Meter
- Controlled Glycemic Module
- Combined Glucose Measurement
Correct answer: Continuous Glucose Monitor
CGM stands for Continuous Glucose Monitor, a device that tracks interstitial glucose levels in real time throughout the day and night.
Question 2: What is the typical warm-up (initialization) period for most implantable or sensor-based CGM devices?
- 30 minutes
- 2 hours (Correct answer)
- 12 hours
- 24 hours
Correct answer: 2 hours
Most CGM sensors require approximately a 2-hour warm-up period after insertion before providing accurate glucose readings.
Question 3: Which setting on an insulin pump delivers a constant baseline amount of insulin throughout the day?
- Bolus dose
- Basal rate (Correct answer)
- Correction factor
- Insulin-to-carb ratio
Correct answer: Basal rate
The basal rate on an insulin pump delivers a steady, pre-programmed amount of insulin continuously to manage background glucose levels.
Question 4: What is a 'time in range' (TIR) target recommended for most adults with diabetes using CGM?
- Greater than 50%
- Greater than 70% (Correct answer)
- Greater than 85%
- Greater than 90%
Correct answer: Greater than 70%
The International Consensus on Time in Range recommends that most adults with diabetes spend greater than 70% of time with glucose between 70–180 mg/dL.
Question 5: Which feature of a hybrid closed-loop insulin delivery system automatically adjusts insulin delivery?
- Manual bolus calculator only
- Algorithm that responds to CGM readings (Correct answer)
- Fixed basal-bolus schedule
- Glucagon co-secretion
Correct answer: Algorithm that responds to CGM readings
A hybrid closed-loop system uses an algorithm that continuously reads CGM data and automatically adjusts basal insulin delivery to maintain target glucose levels.
Question 6: When educating a patient about insulin pump therapy, which situation requires them to return to multiple daily injections temporarily?
- During mild exercise
- During pump site rotation
- When the pump malfunctions or site occludes (Correct answer)
- When eating a low-carb meal
Correct answer: When the pump malfunctions or site occludes
Patients must have a backup plan with multiple daily injections in case of pump malfunction, site occlusion, or unexpected pump failure.
