AI in Diabetes Management Quiz

Answers and explanations appear as you take the quiz.

1. What does a continuous glucose monitor (CGM) measure?
   • Blood pressure every hour
   • Glucose in the fluid under the skin every few minutes
   • Insulin levels in the blood
   • Retinal blood vessel damage
2. Which system did the FDA approve in 2016 as the first hybrid closed-loop insulin system?
   • Omnipod 5
   • Beta Bionics iLet
   • Tandem Control-IQ
   • Medtronic MiniMed 670G
3. What does 'hybrid' mean in a hybrid closed-loop system?
   • Users generally still announce meals or give meal boluses
   • The system uses both insulin and glucose tablets
   • It works with both type 1 and type 2 diabetes only
   • It combines a CGM with a smartwatch
4. What kind of algorithms do most automated insulin delivery systems use?
   • Large language models
   • Image recognition networks
   • Control algorithms such as model predictive control or PID control
   • Random number generators
5. Why was the 2018 FDA authorization of IDx-DR significant?
   • It was the first insulin pump
   • It was the first autonomous AI diagnostic system, reading retinal images without a clinician interpreting them
   • It was the first CGM
   • It cured diabetic retinopathy
6. Why are glucose forecasts judged with error grids such as Clarke or Parkes?
   • Error grids are faster to compute
   • They measure battery life
   • They are required only for retinal screening
   • They weight errors by clinical risk, since some mistakes are more dangerous than others
7. Why must insulin controllers act on predicted glucose rather than current readings?
   • Current readings are never accurate
   • Pumps cannot read current values
   • CGM readings lag blood glucose and insulin takes time to reach peak effect
   • Regulators forbid using current readings
8. Why are image-quality checks essential in autonomous retinopathy screening?
   • The system must reject ungradable photos rather than guess
   • They make images look better for patients
   • They remove the need for a camera
   • They speed up insulin delivery
