Technology in Diabetes Flashcards

A patient with type 1 diabetes on a closed-loop system is planning a 4-hour drive. Which action is MOST appropriate regarding insulin delivery?

Answer: Set a temporary higher glucose target or activity mode during driving

Setting a higher glucose target or activity mode reduces insulin delivery risk during prolonged sedentary activity and accounts for any risk of hypoglycemia while driving.

Which factor is MOST important when selecting a CGM system for a patient with chronic kidney disease on hemodialysis?

Answer: Potential for glucose reading inaccuracies due to uremia and dialysis-related glucose fluctuations

Uremia and hemodialysis can impair CGM accuracy; clinicians should counsel patients and use CGM data cautiously, especially peri-dialysis.

A patient's Dexcom CGM requires two fingerstick calibrations daily. Which generation of the Dexcom system does this describe?

Answer: Dexcom G5 Mobile

The Dexcom G5 Mobile required two fingerstick calibrations per day; the G6 and G7 are factory-calibrated and require no routine calibration.

Which CGM glucose alert setting is most directly linked to reducing severe hypoglycemia events while minimizing alarm fatigue?

Answer: Setting the low alert at 70 mg/dL with a 30-minute snooze

A 70 mg/dL low alert with a 30-minute snooze balances early hypoglycemia warning with reduced alarm fatigue, aligning with standard hypoglycemia thresholds.

A patient reports her insulin pump's reservoir only delivers 80% of the programmed dose. After ruling out occlusion, the MOST likely technical cause is:

Answer: Air bubbles in the reservoir or tubing causing delivery errors

Air bubbles in the reservoir or infusion tubing are a well-known cause of under-delivery in insulin pumps, as the motor displaces air rather than insulin.

Which finding on an AGP report would prompt immediate clinical concern for nocturnal hypoglycemia requiring intervention?

Answer: Time below 54 mg/dL (Level 2) of 2% between midnight and 6 AM

Time below 54 mg/dL >1% (especially concentrated overnight) exceeds the international consensus threshold and requires immediate intervention to prevent serious hypoglycemia.

Which BEST describes the role of 'smart insulin pens' compared to connected insulin pens in diabetes technology?

Answer: Smart pens include a dose calculator using CGM data; connected pens primarily record what was delivered

Smart pens integrate with CGM and insulin-on-board data to calculate suggested doses; connected pens focus primarily on dose capture and logging.
