CBDCE Diabetes Technology and Monitoring Flashcards

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

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

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

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?

Answer: Sensor placed correctly in healthy tissue

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

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

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

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

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?

Answer: Ambulatory Glucose Profile (AGP)

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.

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

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

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.

Which of the following best describes 'Time Below Range' (TBR) in CGM reporting and its clinical significance?

Answer: Time glucose is below 70 mg/dL, indicating hypoglycemia burden

TBR measures the percentage of time glucose is below 70 mg/dL (Level 1 hypoglycemia) or below 54 mg/dL (Level 2), quantifying hypoglycemia burden for clinical decision-making.
