  1. In standard sleep study scoring, what unit of time is each sleep stage label assigned to?
    • Each 5-minute block
    • Each 30-second epoch
    • Each hour
    • Each breath
  2. What does the apnea-hypopnea index measure?
    • Total hours of REM sleep
    • Average heart rate during sleep
    • Apneas plus hypopneas per hour of sleep
    • Minutes of snoring per night
  3. In adults, an AHI of 32 would usually be classified as what?
    • Severe
    • Normal
    • Mild
    • Moderate
  4. Which sleep stage do human scorers agree on least often?
    • REM
    • N3
    • Wake
    • N1
  5. Why is a wearable sleep score not the same as a polysomnogram?
    • Wearables record more brain signals than a lab
    • Wearables usually estimate stages from movement and heart rate rather than EEG brain waves
    • Wearables only work during the day
    • Polysomnograms do not measure breathing
  6. What is the appropriate response to a smartwatch sleep apnea notification?
    • Start treatment immediately
    • Ignore it, since watches are never accurate
    • Treat it as a prompt to see a doctor and get a proper sleep test
    • Delete the app
  7. How do FDA-cleared autoscoring tools typically fit into a sleep lab's workflow?
    • They pre-score studies, and qualified staff review and correct the results
    • They replace the sleep physician
    • They are only used for research
    • They score only the first hour of sleep
  8. Why can the hypopnea scoring rule change a patient's diagnosis?
    • It changes the length of the epochs
    • It decides whether EEG is recorded
    • It only applies to children
    • Using a 3 percent versus 4 percent oxygen-drop rule changes how many events count, which can shift the AHI category
