Question 1

A patient using a hybrid closed-loop insulin pump system reports frequent nocturnal hypoglycemia despite the system's auto-suspend feature. Which adjustment is MOST appropriate?

Accepted Answer

Raise the glucose target set point and review carbohydrate ratios

Answer

Raising the target set point gives the algorithm more headroom to reduce insulin delivery and prevent nocturnal lows.

Question 2

Which CGM accuracy metric is used to assess the proportion of sensor glucose values within ±20% (or ±20 mg/dL) of reference blood glucose?

Accepted Answer

%20/20

Answer

The %20/20 criterion measures the percentage of paired CGM-reference readings that fall within 20% or 20 mg/dL of the reference, depending on glucose level.

Question 3

A patient's CGM shows a rapid-drop arrow (↓↓) at a glucose of 110 mg/dL before exercise. What is the MOST appropriate immediate action?

Accepted Answer

Consume 15–30 g of fast-acting carbohydrates

Answer

A rapidly falling glucose with a double-down arrow before exercise indicates impending hypoglycemia, requiring preemptive carbohydrate intake.

Question 4

Which feature distinguishes a 'predictive low glucose suspend' (PLGS) system from a basic 'low glucose suspend' (LGS) system?

Accepted Answer

PLGS suspends insulin based on a projected future low rather than a current low threshold

Answer

PLGS uses CGM trend data to predict a future low and suspends insulin delivery before the threshold is actually reached.

Question 5

In time-in-range (TIR) reporting, the international consensus target for adults with type 1 diabetes is TIR >70% in the range of:

Accepted Answer

70–180 mg/dL

Answer

The consensus target for adults with T1D is >70% TIR within 70–180 mg/dL.
