  1. What is an insulin pump (CSII) used for in diabetes management?

    Answer: Delivering continuous subcutaneous insulin infusion to replace multiple daily injections

    CSII (Continuous Subcutaneous Insulin Infusion) delivers a programmed basal rate of insulin plus patient-activated bolus doses via a small catheter inserted under the skin.

  2. What is a closed-loop automated insulin delivery (AID) system?

    Answer: A system where CGM data automatically adjusts insulin pump delivery without user input

    Automated Insulin Delivery (AID) systems use CGM data and an algorithm to automatically adjust insulin pump delivery in real time, sometimes called an 'artificial pancreas.'

  3. A patient using an insulin pump reports unexplained hyperglycemia. What is the first troubleshooting step a CDCES should recommend?

    Answer: Check the infusion site and tubing for occlusion, air bubbles, or dislodgement

    Unexplained hyperglycemia in pump users most commonly results from infusion site problems such as occlusion, kinking, air in tubing, or site dislodgement.

  4. What is the recommended infusion site rotation interval for insulin pump users to prevent lipohypertrophy?

    Answer: Change every 2–3 days

    Insulin pump infusion sets should be changed every 2–3 days and sites should be rotated systematically to prevent lipohypertrophy and maintain insulin absorption.

  5. Which insulin is used in most insulin pumps?

    Answer: Rapid-acting insulin analogs (e.g., lispro, aspart, glulisine)

    Insulin pumps use only rapid-acting insulin analogs to provide both basal rates (tiny continuous doses) and mealtime boluses.

  6. What does 'time below range' (TBR) refer to in CGM ambulatory glucose profile reporting?

    Answer: Percentage of time glucose is below 70 mg/dL

    Time Below Range (TBR) is the percentage of CGM readings below 70 mg/dL and is a key safety metric for assessing hypoglycemia burden.
