Question 1

What does the acronym 'AGP' refer to in CGM reporting?

Accepted Answer

Ambulatory Glucose Profile

Answer

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?

Accepted Answer

Coefficient of variation (CV)

Answer

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?

Accepted Answer

No tubing, worn directly on the skin

Answer

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?

Accepted Answer

5–15 minutes

Answer

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?

Accepted Answer

Acetaminophen ingestion (older electrochemical sensors)

Answer

Acetaminophen can interfere with older electrochemical CGM sensors, causing falsely elevated or low readings depending on the sensor technology.
