RPSGT DOMAIN 3 Sleep stages Practice Quizzes Q & A 2024 Question 1: Which stage of sleep is characterized by the presence of theta waves and the appearance of sleep spindles and K-complexes on an EEG? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: b) Stage 2 Rationale: Stage 2 sleep is characterized by the presence of theta waves and the appearance of sleep spindles and K- complexes on an EEG. This stage represents approximately 45-55% of total sleep time and is essential for the consolidation of memory and learning. Question 2: Which stage of sleep is often referred to as slow-wave sleep (SWS) and is characterized by the presence of high-amplitude, low-frequency delta waves on an EEG? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: c) Stage 3 Answer: c) Stage 3 Rationale: Stage 3 sleep, or slow-wave sleep, is most prominent during the first half of the night, while REM sleep becomes more prevalent during the second half. This pattern is characteristic of the sleep cycle. Question 7: What term is used to describe the transition period between wakefulness and sleep, characterized by the presence of alpha and theta brain waves? a) Hypnagogic state b) Hypnopompic state c) Sleep onset d) Sleep paralysis Answer: a) Hypnagogic state Rationale: The hypnagogic state refers to the transition period between wakefulness and sleep, characterized by the presence of alpha and theta brain waves. It is often accompanied by vivid sensory experiences and fleeting thoughts. Question 8: Which stage of sleep is associated with a decreased heart rate, blood pressure, and body temperature, as well as reduced muscle tone? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: d) REM sleep Rationale: REM sleep is associated with a decreased heart rate, blood pressure, and body temperature, as well as reduced muscle tone. These physiological changes contribute to the restorative nature of REM sleep. Question 9: Which sleep disorder is characterized by a recurring pattern of disrupted breathing during sleep, leading to fragmented sleep and excessive daytime sleepiness? a) Insomnia b) Narcolepsy c) Restless Legs Syndrome d) Obstructive Sleep Apnea Answer: d) Obstructive Sleep Apnea Rationale: Obstructive Sleep Apnea is characterized by a recurring pattern of disrupted breathing during sleep, leading to fragmented sleep and excessive daytime sleepiness. It is often associated with snoring and pauses in breathing. Question 10: What term is used to describe the inability to fall or stay asleep, leading to daytime impairment and distress? a) Insomnia b) Hypersomnia c) Parasomnia d) Sleep Apnea Answer: a) Insomnia Rationale: Insomnia refers to the inability to fall or stay asleep, leading to daytime impairment and distress. It can be caused by various factors, including stress, anxiety, and poor sleep habits. Question 11: Which of the following is a characteristic feature of REM sleep behavior disorder (RBD)? a) Sleepwalking b) Night terrors c) Sleep paralysis d) Acting out dreams Answer: d) Acting out dreams Rationale: REM sleep behavior disorder (RBD) is characterized by the acting out of dreams during REM sleep. This can result in disruptive and potentially dangerous behaviors during sleep. complex behaviors while asleep, such as walking, eating, or performing activities, without full awareness. It typically occurs during non-REM sleep. Question 16: What term is used to describe the repetitive grinding or clenching of the teeth during sleep? a) Insomnia b) Narcolepsy c) Restless Legs Syndrome d) Sleep bruxism Answer: d) Sleep bruxism Rationale: Sleep bruxism refers to the repetitive grinding or clenching of the teeth during sleep. It can lead to dental problems, jaw pain, and disrupted sleep. Question 17: Which stage of sleep is most closely associated with the restoration of physical and mental energy? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: c) Stage 3 Rationale: Stage 3 sleep, or slow-wave sleep, is most closely associated with the restoration of physical and mental energy. It is essential for overall well-being and body repair processes. Question 18: What term is used to describe the phenomenon of experiencing vivid, often frightening, sensory experiences during the transition from wakefulness to sleep? a) Insomnia b) Night terrors c) Hypnagogic hallucinations d) Sleep paralysis Answer: c) Hypnagogic hallucinations Rationale: Hypnagogic hallucinations refer to the phenomenon of experiencing vivid, often frightening, sensory experiences during the transition from wakefulness to sleep. They are commonly associated with narcolepsy. Question 19: Which stage of sleep is characterized by the presence of alpha and theta brain waves, as well as hypnic jerks and myoclonic twitches? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: a) Stage 1 Rationale: Stage 1 sleep is characterized by the presence of alpha and theta brain waves, as well as hypnic jerks and myoclonic twitches. This stage represents the transition from wakefulness to sleep. Question 20: What term is used to describe the state of excessive daytime sleepiness and a tendency to fall asleep in inappropriate situations? a) Insomnia b) Narcolepsy c) Restless Legs Syndrome d) Sleep Apnea Answer: b) Narcolepsy Rationale: Narcolepsy is characterized by excessive daytime sleepiness and a tendency to fall asleep in inappropriate situations. It can also involve symptoms such as cataplexy, sleep paralysis, and hypnagogic hallucinations. Question 21: Which sleep disorder is characterized by a sudden and uncontrollable urge to sleep during the day, often resulting in episodes of microsleep? a) Insomnia b) Narcolepsy most vivid and emotionally intense dreams? a) Stage 1 b) Stage 2 c) Stage 3 d) REM sleep Answer: d) REM sleep Rationale: REM sleep is associated with the most vivid and emotionally intense dreams. This stage plays a crucial role in emotional processing and memory consolidation during sleep. 1.
