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

CGM readings are always more accurate than fingerstick meters

Answer

CGM automatically adjusts insulin doses

Answer

Sensors never require replacement

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

Sensor placed in an area with lipohypertrophy

Answer

Rapid glucose change causing physiological lag

Answer

Sensor nearing end of wear life

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

Deliver insulin automatically based on CGM readings

Answer

Contain both basal and bolus insulin in one pen

Answer

Eliminate the need for needle changes

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

A1C lab result

Answer

Fasting glucose log

Answer

7-day average glucose printout

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 are MRI-safe and can always be worn

Answer

Only the transmitter must be removed, not the sensor

Answer

CGM is safe during MRI if the field strength is below 3 Tesla

Question 6

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

Accepted Answer

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

Answer

Time glucose is above 250 mg/dL, indicating dangerous hyperglycemia

Answer

Time glucose is between 70–180 mg/dL, the target range

Answer

Time the CGM sensor is not transmitting data
