Question 1

A closed-loop system increases basal insulin delivery yet the patient's postprandial glucose rises to 280 mg/dL consistently. The MOST likely explanation is:

Accepted Answer

The patient is not pre-bolusing for meals

Answer

Closed-loop systems optimize basal insulin but rely on patient-entered meal boluses; skipping pre-bolus causes postprandial spikes the algorithm cannot fully correct in real time.

Question 2

Which factor MOST significantly impairs CGM accuracy during rapid glucose changes?

Accepted Answer

Physiological lag between interstitial and blood glucose

Answer

Interstitial glucose lags behind blood glucose by approximately 5–10 minutes, causing CGM readings to underestimate or overestimate during rapid changes.

Question 3

What does a coefficient of variation (CV) >36% on a patient's CGM report indicate?

Accepted Answer

High glycemic variability requiring management

Answer

A CV >36% reflects high glycemic variability, which is associated with increased hypoglycemia risk and poor metabolic control independent of mean glucose.

Question 4

A patient with type 2 diabetes on basal insulin is considering a connected insulin pen. Which benefit is MOST relevant to their diabetes management?

Accepted Answer

Dose logging and reminders to reduce missed or duplicate injections

Answer

Connected insulin pens record dose timing and amount, helping patients and clinicians identify missed or duplicate injections that drive glucose variability.

Question 5

According to the AGP (Ambulatory Glucose Profile) report, which metric best reflects overnight hypoglycemia burden?

Accepted Answer

Time below range <54 mg/dL (Level 2 low)

Answer

Time below range <54 mg/dL (Level 2 hypoglycemia) is the metric most directly reflecting serious hypoglycemia burden, with a target of <1%.
