  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?

    Answer: Raise the glucose target set point and review carbohydrate ratios

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

  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?

    Answer: %20/20

    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.

  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?

    Answer: Consume 15–30 g of fast-acting carbohydrates

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

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

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

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

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

    Answer: 70–180 mg/dL

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

  6. A patient using flash glucose monitoring (FGM) asks why alarms do not alert her to hypoglycemia overnight. The BEST explanation is:

    Answer: Flash glucose monitors do not have real-time alarms; they require active scanning

    Unlike CGM, FGM (e.g., FreeStyle Libre 1) is a scan-on-demand system with no automatic alarms unless the user scans the reader over the sensor.

  7. Which insulin pump infusion set change interval is generally recommended to minimize the risk of lipohypertrophy and site infections?

    Answer: Every 48–72 hours

    Infusion sets should be rotated and changed every 48–72 hours to prevent lipohypertrophy, infection, and unexplained hyperglycemia.
