What is the recommended action before a patient with an insulin pump undergoes an MRI scan?
Answer: Remove the pump before the MRI
Insulin pumps must be removed before MRI because the strong magnetic field can damage the device and potentially harm the patient.
Which glucose alert threshold on a CGM is used to warn a patient of an impending low before it occurs?
Answer: Predictive low glucose alert
A predictive low glucose alert notifies the patient that their glucose is trending toward hypoglycemia before the actual low occurs, allowing preventive action.
When a patient uses an automated insulin delivery (AID) system, meals still require which manual patient action?
Answer: Announcing the meal by entering a meal bolus
Even with a hybrid closed-loop AID system, patients must manually announce meals and deliver a meal bolus because the system cannot anticipate food intake independently.
What does 'GMI' (Glucose Management Indicator) estimate on a CGM report?
Answer: Approximate HbA1c based on CGM mean glucose
GMI estimates an approximate HbA1c level derived from the CGM's mean glucose data over a period of at least 14 days.
A patient reports that their CGM alarm woke them at night but their fingerstick showed glucose was normal. What term describes this scenario?
Answer: False positive alarm
A false positive alarm occurs when the CGM alerts the patient to a glucose problem that does not actually exist, reducing trust and causing alarm fatigue.
Which insulin pump feature allows a patient to deliver insulin more slowly over a set time period, useful for high-fat meals?
Answer: Extended (square wave) bolus
An extended or square wave bolus delivers insulin gradually over a user-defined period, helping manage the delayed glucose rise from high-fat or high-protein meals.
