Question 1

Which of the following is a key patient education point when initiating CGM therapy regarding sensor accuracy?

Accepted Answer

Patients should calibrate or verify CGM readings with a fingerstick during symptoms of hypoglycemia if using a non-factory-calibrated sensor

Answer

During symptomatic hypoglycemia or when symptoms do not match CGM readings, patients using non-factory-calibrated CGMs should verify with a fingerstick before treating.

Question 2

A patient reports that their CGM readings are consistently 20–30 mg/dL higher than fingerstick readings. Which factor is LEAST likely to cause this discrepancy?

Accepted Answer

Sensor placed correctly in healthy tissue

Answer

A sensor correctly placed in healthy tissue is expected to perform accurately; the other three factors are known causes of CGM-fingerstick discrepancy.

Question 3

Smart insulin pens differ from standard insulin pens in that they:

Accepted Answer

Record the time and dose of each injection and may connect to a smartphone app

Answer

Smart insulin pens contain dose-capture technology that logs injection time and amount, helping patients and clinicians track MDI adherence and identify dosing patterns.

Question 4

When downloading a patient's CGM data for a clinic visit, which standardized report provides the most comprehensive view of glucose patterns, including TIR, TBR, and variability metrics?

Accepted Answer

Ambulatory Glucose Profile (AGP)

Answer

The Ambulatory Glucose Profile (AGP) is the standardized, single-page report that displays 14+ days of CGM data including TIR, TBR, TAR, CV, and a modal day curve.

Question 5

A patient with type 1 diabetes asks whether they should wear their CGM during an MRI scan. What should a CDCES advise?

Accepted Answer

The sensor and transmitter must be removed before entering the MRI room

Answer

CGM sensors and transmitters contain metal components that can be damaged by MRI magnetic fields and radiofrequency energy; both must be removed before entering the MRI room.
