Sleep/Wakefulness Disorders
Sleep/Wakefulness Disorders ( 40 Questions)
A nurse is conducting a teaching session on types of sleep and wakefulness disorders. Which of the following classifications is characterized by abnormal behavioral, experiential, physiological, or psychological events occurring during sleep or sleep-wake transitions?
Insomnia refers to the difficulty of initiating or maintaining sleep or experiencing nonrestorative sleep, often resulting in daytime impairments. It doesn't involve abnormal behavioral or physiological events during sleep, making it an incorrect choice.
Hypersomnolence is characterized by excessive daytime sleepiness and prolonged nighttime sleep, but it doesn't encompass abnormal events during sleep. It focuses on excessive sleep rather than abnormal behaviors or experiences during sleep.
Circadian rhythm sleep-wake disorders involve disruptions in the sleep-wake cycle due to misalignment with the natural circadian rhythm. While this can lead to difficulties in falling asleep or staying awake at desired times, it doesn't specifically account for abnormal behavioral or experiential events during sleep.
Parasomnias involve abnormal behaviors, experiences, physiological events, or psychological events occurring during sleep or sleep-wake transitions. These include disorders like sleepwalking, night terrors, sleep-related eating disorders, and rapid eye movement (REM) sleep behavior disorder. These behaviors are outside the range of normal sleep activities and differentiate parasomnias from other sleep disorders.
Choice A rationale:
Insomnia refers to the difficulty of initiating or maintaining sleep or experiencing nonrestorative sleep, often resulting in daytime impairments. It doesn't involve abnormal behavioral or physiological events during sleep, making it an incorrect choice.
Choice B rationale:
Hypersomnolence is characterized by excessive daytime sleepiness and prolonged nighttime sleep, but it doesn't encompass abnormal events during sleep. It focuses on excessive sleep rather than abnormal behaviors or experiences during sleep.
Choice C rationale:
Circadian rhythm sleep-wake disorders involve disruptions in the sleep-wake cycle due to misalignment with the natural circadian rhythm. While this can lead to difficulties in falling asleep or staying awake at desired times, it doesn't specifically account for abnormal behavioral or experiential events during sleep.
Choice D rationale:
Parasomnias involve abnormal behaviors, experiences, physiological events, or psychological events occurring during sleep or sleep-wake transitions. These include disorders like sleepwalking, night terrors, sleep-related eating disorders, and rapid eye movement (REM) sleep behavior disorder. These behaviors are outside the range of normal sleep activities and differentiate parasomnias from other sleep disorders.
