Diabetes Education Certification Diabetes Technology & Devices 2 — Questions and Answers
Question 1: What does the acronym 'AGP' refer to in CGM reporting?
- Average Glucose Profile
- Ambulatory Glucose Profile (Correct answer)
- Adjusted Glycemic Pattern
- Annual Glucose Panel
Correct answer: Ambulatory Glucose Profile
AGP stands for Ambulatory Glucose Profile, a standardized one-page CGM report that summarizes glucose patterns to guide clinical decision-making.
Question 2: Which CGM metric reflects the variability of glucose readings and is expressed as a percentage?
- Mean glucose
- Time in range
- Coefficient of variation (CV) (Correct answer)
- GMI (Glucose Management Indicator)
Correct answer: Coefficient of variation (CV)
The coefficient of variation (CV) measures glucose variability; a CV ≤36% is generally considered stable glucose control.
Question 3: What is the primary advantage of a patch pump (tubeless insulin pump) over a traditional tethered pump?
- Lower insulin cost
- No tubing, worn directly on the skin (Correct answer)
- Longer sensor life
- Built-in glucagon delivery
Correct answer: No tubing, worn directly on the skin
A patch pump is tubeless and adheres directly to the skin, eliminating external tubing and offering a more discreet, flexible option for active patients.
Question 4: A diabetes educator should advise CGM users that sensor glucose readings may lag behind blood glucose by approximately how many minutes?
- 1–2 minutes
- 5–15 minutes (Correct answer)
- 30–45 minutes
- 60–90 minutes
Correct answer: 5–15 minutes
CGM measures interstitial fluid glucose, which typically lags behind blood glucose by 5–15 minutes, particularly during rapid glucose changes.
Question 5: Which condition can cause falsely low CGM readings and should be considered when calibrating or interpreting results?
- High altitude exposure
- Acetaminophen ingestion (older electrochemical sensors) (Correct answer)
- Caffeine consumption
- Dehydration only
Correct answer: Acetaminophen ingestion (older electrochemical sensors)
Acetaminophen can interfere with older electrochemical CGM sensors, causing falsely elevated or low readings depending on the sensor technology.
Question 6: In pump therapy, what is a 'correction bolus' (also called a supplemental bolus)?
- Insulin given to cover a meal
- Extra insulin given to bring high glucose back to target (Correct answer)
- The basal rate multiplied by hours
- A bolus given before exercise
Correct answer: Extra insulin given to bring high glucose back to target
A correction bolus is additional insulin delivered to lower an elevated blood glucose level back toward the patient's target range.
