Answers and explanations appear as you take the quiz.

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
