Questions: 16 · 10 minutes

Obstructive sleep apnea
Delayed sleep-wake phase disorder
Restless legs syndrome
Sleepwalking disorder
2. When does sleepwalking most commonly arise?
During REM sleep near morning, usually with vivid dream recall

This may reflect insufficient sleep opportunity rather than a sleep disorder
This confirms a circadian rhythm disorder
This is most typical of REM sleep behavior disorder
5. A person consistently cannot fall asleep until very late, struggles to wake for morning obligations, but sleeps normally on a preferred late schedule. What best explains the pattern?
Nightmare disorder
Restless legs syndrome
REM sleep behavior disorder
Delayed sleep-wake phase disorder
6. Which observation most specifically suggests sleep-disordered breathing rather than insomnia alone?
Worrying about tomorrow while trying to fall asleep
Witnessed breathing pauses followed by choking or gasping
Checking the clock repeatedly during the night
Feeling more alert after an evening activity
7. Which description is most characteristic of restless legs syndrome?
Repeated breathing pauses that occur only during dreams
An uncomfortable urge to move the legs that worsens at rest and often improves with movement
Leg cramps caused exclusively by strenuous exercise

An obstruction of the airway during sleep
A permanent inability to enter REM sleep
A temporary mismatch between the internal body clock and local time
An urge to move the legs caused by inactivity
11. A clinician suspects obstructive sleep apnea and wants comprehensive overnight measurements of sleep stages, breathing, and oxygen levels. Which test most directly provides them?
A daytime mood questionnaire
A structural brain MRI
A dream-content journal
Overnight polysomnography
12. What is the main purpose of a sleep diary during a sleep evaluation?
To record patterns such as bedtimes, awakenings, naps, and daytime sleepiness
To identify the exact medical cause of every awakening
To replace a clinical history and physical examination
To measure brain waves and blood oxygen directly
13. What most clearly distinguishes insomnia disorder from an occasional bad night of sleep?
Sleeping fewer hours than another person of the same age
Any night when it takes longer than usual to fall asleep
Persistent trouble sleeping despite adequate opportunity, accompanied by daytime impairment

Cataplexy
Sleepwalking
