Prep U Ch. 22 Sleep Disorders
An elderly patient is brought to the clinic by her daughter who informs the nurse that her mother is having terrible nightmares and does not know what to do about them. The patient does not sleep well and is very tired. What does the nurse suspect the diagnostic label to be for this patient? a) Sleep apnea b) Sleep-related movement disorder c) Insomnia d) Parasomnia
Parasomnia Explanation: Parasomnias are primary sleep disorders characterized by unusual or undesirable behaviors during sleep. They interfere with sleep or happen during the threshold between sleep and wakefulness. Examples include nightmares, sleepwalking, and sleep terrors.
Narcolepsy, a disorder characterized by excessive daytime sleepiness and cataplexy (sudden bilateral loss of postural muscle tone), is effectively treated with ... a) SSRIs. b) administration of methylphenidate (Ritalin). c) behavior modification techniques. d) discouraging daytime napping.
b) administration of methylphenidate (Ritalin).
A nursing student correctly identifies which of the following to be true about adolescence and sleep? a) Inadequate sleep does not interfere with daily activities. b) Circadian changes in sleep timing, particularly later bedtimes, may be normal in adolescence. c) Teenagers normally get at least 9 hours of sleep. d) Experts say that teenagers need approximately 12 hours of sleep each night.
Circadian changes in sleep timing, particularly later bedtimes, may be normal in adolescence. Explanation: Circadian changes in sleep timing, particularly later bedtimes, may be normal in adolescence. Experts say teenagers need about 9 hours of sleep but they usually get 7 to 8 hours. Inadequate sleep is a health concern for pediatric populations
A nurse is reading a journal article about sleep-wake disorders. The article mentions a REM disorder. Which of the following would the nurse expect to be discussed? a) Sleep walking b) Nightmare disorder c) Restless leg syndrome d) Sleep terrors
Nightmare disorder Explanation: Nightmare disorder is a rapid eye movement (REM) disorder that generally occurs during the second half of the major sleep episode. Non-rapid eye movement (NREM) sleep arousal disorders, including sleepwalking and sleep terror types, usually occur the first third of the major sleep episode. Restless legs syndrome is considered a sleep disorder and is classified as a parasomnia.
Which of the following parasomnias occur primarily in children in the Non-REM stage and may result in emotional experiences that are frightening? a) Confusional arousals b) Sleep terrors c) Sleepwalking d) Nightmares
Sleep terrors Explanation: Sleep terrors occur primarily in children, and in the non-REM sleep stage resulting in frightening thoughts. Nightmares occur in the REM sleep stage.
A geriatrician is assessing an 84-year-old male recently admitted to a subacute medical unit of a hospital for rehabilitation following recent falls and a hip contusion. Which of the following aspects of the client's sleep history would the physician want to follow up with education? a) "I try my best to get out for a walk after breakfast or after supper." b) "I make it a rule not to drink any alcohol in the evening." c) "I make sure that I take a long nap each afternoon to compensate for my frequent waking at night." d) "I've got a bottle of diazepam at home, but I only take them once or twice a month."
"I make sure that I take a long nap each afternoon to compensate for my frequent waking at night." Explanation: Daytime sleeping can interfere with the normal sleep-wake cycle. Occasional use of hypnotics is acceptable and moderate exercise that is not performed before bedtime can help with insomnia. Alcohol can inhibit sleep in older adults.
A young adult comes to the sleep clinic and reports not getting enough sleep and rest. The client reports needing a drink of alcohol to fall asleep. What should the nurse tell this client about alcohol's effect on sleep? a) "The short-term effects of alcohol will be beneficial to your sleep." b) "Alcohol should not have any effect on your sleep." c) "Long-term effects of alcohol are arousal and wakefulness." d) "Alcohol causes restful sleep; continue using it."
"Long-term effects of alcohol are arousal and wakefulness." Explanation: Many people use alcohol to self-treat insomnia. Although its acute sedative effects lead to drowsiness and shorten sleep latency, long-term effects include arousal and wakefulness. Once alcohol is metabolized (4-5 hours), withdrawal results in shallow and disturbed sleep as well as other symptoms.
A client asks the nurse, "What causes insomnia?" Which response by the nurse would be most appropriate? a) "No one factor is associated with causing insomnia." b) "It is one of the few disorders caused by a chemical imbalance." c) "Most cases involve some type of posttraumatic stress." d) "Individuals with insomnia have an underlying mental health problem."
"No one factor is associated with causing insomnia." Explanation: Many factors affect sleep, but there is no one factor that causes insomnia. One of the major reasons for insomnia is depression, which accounts for most cases. However, most people with insomnia do not have psychiatric diagnosis

A nursing instructor is teaching a class on sleep and rest to first year nursing students. The instructor realizes a need for further education when one of the students makes which statement? a) "Changes in sleep patterns may be a sign of other medical conditions." b) "Pain is a cause of sleep disturbance." c) "Sleep disturbance is part of normal aging." d) "Sleep disturbance can be caused by nocturia
"Sleep disturbance is part of normal aging." Explanation: Sleep disturbance is not a normal part of aging; this mistaken belief may be a barrier for clients to seek help for genuine problems. The other statements are true.
A parent of a 14-year-old male expresses concern over the late hours the teen keeps. Which of the following responses by the nurse best explains a possible etiology for the late hours? a) "You are the parent and need to enforce the bed time rules to show who the boss is." b) "The onset of puberty often lengthen the circadian rhythm causing and increase in evening wakefulness." c) "Your teen needs to be prescribed sleep medications." d) "Your teenager is likely being pressured by peers to stay up late and go against your house rules."
"The onset of puberty often lengthen the circadian rhythm causing and increase in evening wakefulness."
A 77-year-old woman is concerned because she has occasionally found her husband sleepwalking in the last several weeks. What is her care provider's most appropriate response to her concerns? a) "There may be something else going on with your husband such as delirium or a problem with his medications." b) "This is understandably upsetting for you, but as long as the environment is safe it's likely not significant." c) "I'll likely prescribe a benzodiazepine for this when I next see your husband." d) "This is not an uncommon event that often accompanies older age."
"There may be something else going on with your husband such as delirium or a problem with his medications." Explanation: New onset sleepwalking in an older adult is usually a manifestation of another problem such as delirium, drug toxicity or a seizure disorder. It is not a normal age-related change and a benzodiazepine is not a prudent initial treatment.
A nurse is teaching a client with insomnia about stimulus control. Which of the following would the nurse include in the education? a) "You should avoid eating or watching television in your bedroom." b) "You should focus your attention on pleasant images to reduce stress." c) "Let's look at your behavior and thoughts contributing to your problem." d) "Try spending less time in bed along with avoiding any naps."
"You should avoid eating or watching television in your bedroom." Explanation: Stimulus control is a technique used when the bedroom environment no longer provides cues for sleep but has become the cue for wakefulness. Patients are instructed to avoid behaviors in the bedroom incompatible with sleep, including watching television, doing homework, and eating. This allows the bedroom to be reestablished as a stimulus for sleep. Another behavioral intervention is sleep restriction. Clients often increase their time in bed to provide more opportunity for sleep, resulting in fragmented sleep and irregular sleep schedules. Clients are instructed to spend less time in bed and avoid napping. Relaxation training, such as imagery, is used when patients complain of difficulty relaxing, especially if they are physically tense or emotionally distressed. Cognitive behavior therapy helps to identify maladaptive behaviors and cognition that contribute to insomnia
A nurse working in a sleep laboratory is talking to patients about the importance of adequate sleep. The nurse informs them that the timing and patterns of sleep changes as people age. What does the nurse say is the normal amount of sleep needed for INFANTS? a) 10 to 12 hours b) 18 to 20 hours c) 14 to 15 hours d) 8 to 10 hours
14 to 15 hours Explanation: Infants normally spend more time each day asleep than awake. Their 14 to 15 hours of daily sleep usually consists of one or two naps and 10 to 12 hours of nighttime sleep.
After reviewing information about sleep patterns and changes occurring over the lifespan, a group of nursing students demonstrates understanding when they identify that NEWBORNS require how much sleep per day? a) 17 to 18 hours b) 13 to 14 hours c) 8 to 9 hours d) 11 to 12 hours
17 to 18 hours Explanation: Newborns need 17 to 18 hours of sleep each day, which occurs in 3- to 4-hour episodes throughout the day. By age 6 months, 12 hours of sleep at night and two 1- to 2-hour naps each day are needed. After age 5 years, children gradually need less sleep. Preadolescents need about 10 hours of sleep each night, and napping is rare. A teenager's sleep need is only slightly less, at about 9 hours. During young adulthood, about 8 hours of sleep is needed.
A nurse is reading a journal article about sleep. When reviewing the statistics about the average person in the Unites States, which of the following would the nurse most likely find as the average duration of sleep? a) 9 to 9.5 hours b) 6 to 6.5 hours c) 7 to 7.5 hours d) 8 to 8.5 hours
6 to 6.5 hours Explanation: The average sleep duration of adults in the U. S. has plateaued between 6 and 6.5 hours from a high of 8.5 hours in 1960.
Which of the following individuals would be expected to have the highest risk of developing sleep apnea? a) A man with poorly controlled diabetes and hypertension b) A female with chronic insomnia and atrial fibrillation that is treated with warfarin c) A woman with restless leg syndrome and chronic obstructive pulmonary disease d) A male client with a diagnosis of unstable angina and peripheral vascular disease
A man with poorly controlled diabetes and hypertension Explanation: Male gender, diabetes and hypertension are all associated with sleep apnea. COPD, angina, PVD and atrial fibrillation are not noted to be strongly associated with sleep apnea.
Which of the following findings during sleep observations of clients in a sleep lab would be most likely to be considered pathologic? a) A man experiences periods of apnea of 5 to 15 seconds in duration b) A woman's intrinsic clock involves a sleep-wake cycle that is consistently two hours longer than the actual length of a day c) A woman spends the majority of her sleeping hours in REM sleep d) A man's PCO2 is increased and his PO2 decreased during deep sleep
A woman spends the majority of her sleeping hours in REM sleep Explanation: While vital, REM sleep does not normally occupy the majority of sleeping hours. Brief apneic spells are not uncommon and the circadian rhythm often does not match the 24-hour length of day. It is normal for PCO2 to increase and PO2 to decrease during deep sleep.

A physician is providing care for a 40-year-old male who is experiencing chronic insomnia in recent months while going through a divorce and child custody proceedings. The man is requesting a prescription for "sleeping pills" to help him through this time. Which of the following statements forms a valid basis for the physician's plan for treatment? a) Melatonin supplements will be the safest and most effective long term pharmacological treatment b) Behavioral therapies, counseling and education may be of some use for the client c) Sedatives and hypnotic drugs will not provide safe relief of the man's health problem d) The man is suffering from primary insomnia
Behavioral therapies, counseling and education may be of some use for the client Explanation: Behavioral therapies may be beneficial in the treatment of insomnia. Drugs may be of use in the short term and should be used judiciously rather than completely avoided. The efficacy of melatonin is unproven and his insomnia would likely be categorized as secondary insomnia, given the obvious contribution of stressors.
Problems that nurses who work the night shift may encounter more than those who work day shift include ... a) hyperalertness. b) poor concentration. c) lower alcohol tolerance. d) increased risk of errors.
Daily use of caffeine Explanation: Caffeine is a stimulant that results in delayed sleep onset, decreased total sleep time, increased wake after sleep onset, and decreased REM and slow-wave sleep. Caffeine-containing beverages include coffee, tea, cola, chocolate, and some non-cola soft drinks. Caffeine is also found in over-the-counter (OTC) cold preparations and stimulants.
A client comes to the clinic reporting insomnia that began with depression that was diagnosed about 2 months ago. The client informs the nurse that she goes to bed at the same time each night, drinks a glass of warn milk prior to bedtime, and mediates for 20 minutes before turning out the lights. What does the nurse suspect is the cause of this client's insomnia? a) Meditating prior to bedtime b) Not varying bedtime each night c) Drinking milk prior to bedtime d) Depression
Depression Explanation: Many factors affect sleep, but no single factor causes insomnia. One of the major reasons for insomnia is depression, which accounts for many cases.
A client is telling a nurse about a dream that was beautiful, as if the client was actually in a garden with vivid colors and bright flowers. The client was in which stage of sleep during this dream? a) N3 b) N1 c) N2 d) REM
REM Explanation: REM sleep is the stage when dreams have vivid content, full color, and sounds. The person is difficult to wake at this stage.
Which of the following observations of a female client in a sleep lab would indicate to clinicians that she is in REM sleep? a) Her motor movements are suppressed and muscle tone is flaccid. b) Delta waves are evident on her EEG and heart and respiration rates are slowed. c) Rolling eye movements are observed and she has moderate muscle activity. d) She has a low level of cerebral activity and her EEG indicates low voltage and mixed frequencies.
Her motor movements are suppressed and muscle tone is flaccid. Explanation: REM sleep is accompanied by low levels of muscle movement and loss of muscle tone. Rolling eye movements, delta waves and low levels of cerebral activity are associated with stages 1 through 4 of sleep.

A client is diagnosed with narcolepsy. During the interview, the client reports vivid dream-like images when he first falls asleep. The nurse documents this as which of the following? a) Hypnagogic hallucinations b) Daytime sleepiness c) Sleep paralysis d) Cataplexy
Hypnagogic hallucinations Explanation: Hypnagogic hallucinations are intense dreamlike images that occur at sleep onset and usually involve the current environment. Hallucinations can be visual or auditory, such as hearing one's name called or a door slammed. Cataplexy is the bilateral loss of muscle tone triggered by a strong emotion, such as anger or laughter. This muscle atonia can range from subtle (drooping eyelids) to dramatic (buckling knees). Respiratory muscles are not affected. Sleep paralysis, the inability to move or speak when falling asleep or waking up, is often described as terrifying and is accompanied by a sensation of struggling to move or speak. Daytime sleepiness refers to the overwhelming urge to sleep.
An instructor is describing the sleep-wake cycle to a group of nursing students. The instructor determines that the education was successful when the group identifies that the body's biological clock is located in which of the following? a) Hypothalamus b) Temporal lobe c) Frontal cortex d) Pituitary gland
Hypothalamus Explanation: The biologic clock that regulates our circadian rhythms is located in the suprachiasmatic nucleus, an area of the hypothalamus that lies on top of the optic chiasm.
A client who comes to the sleep clinic reports being tired in the morning. Upon further assessment, the client discusses difficulty falling asleep at night and waking up in a bad mood in the morning. The client also acknowledges difficulty staying awake during the day. Which of the following diagnoses would the nurse suspect? a) Depression b) Insomnia c) Restless leg syndrome d) Narcolepsy

Insomnia Explanation: Insomnia, which is a perception of insufficient sleep or not feeling rested after habitual sleep, is the most common sleep disorder in adults.
After teaching a group of nursing students about sleep-wake disorders, the instructor determines that the education was successful when the students identify which of the following as the most prevalent disorder? a) Insomnia b) Obstructive sleep apnea syndrome c) Parasomnia d) Narcolepsy
Insomnia Explanation: Of all the sleep-wake disorders and sleep-related problems, insomnia is the most prevalent.
Which type of circadian rhythm sleep disorder occurs across time zones? a) Delayed sleep type b) Advanced sleep phase type c) Shift type work d) Jet lag type
Jet lag type Explanation: Jet lag occurs after travel across time zones, particularly in coast-to-coast and international travel. Individuals with delayed sleep phase type or "night owls" tend to be unable to fall asleep between 2 and 6 AM; hence, their whole sleep patterns shift, and they have difficulty rising in the morning. The endogenous sleep-wake cycle is normal but is mismatched to the imposed hours of shift work. In advanced sleep phase type, the opposite of the night owls occurs. These individuals are "larks" or earlier risers. They are unable to stay awake in the evening and consistently wake up early.
A nursing student has learned that the sleep-wake cycle is partially regulated by which of the following hormones? a) Estrogen b) Melatonin c) Cortisol d) Cholecystokinin
Melatonin Explanation: Melatonin, a hormone released from the pineal gland, aids in the regulation of the sleep-wake cycle

A client is prescribed Ramelteon (Rozerem). The nurse understands that this drug is classified as which of the following? a) Sedating antidepressant b) Benzodiazepine c) Melatonin receptor agonist d) Nonbenzodiazepine
Melatonin receptor agonist Explanation: Ramelteon is classified as a melatonin receptor agonist. Triazolam is an example of a benzodiazepine. Zolpidem is an example of a nonbenzodiazepine. Trazodone is an example of a sedating antidepressant.
A nurse walks into a client's room to administer medications and finds the client sitting up in a chair. He is holding the newspaper but appears to be sleeping and not reading. His wife tells the nurse that he does this all the time and sometimes falls asleep while driving. For what should the nurse assess this client? a) Insomnia b) Sleep apnea c) Restless leg syndrome d) Narcolepsy
Narcolepsy Explanation: Narcolepsy is an overwhelming urge to sleep that can occur at anytime of the day, regardless of the amount of sleep at night.
When performing a nursing history with a client reporting a sleep disturbance, it is important to assess for which potential contributing factor to sleep difficulties? a) Recent cessation of smoking b) Chronic stress c) Use of over-the-counter antihistamines d) Daily use of caffeine

Restless legs syndrome is considered a sleep disorder and is classified as a parasomnia.
Which of the following motor disorders of sleep can be life threatening? a) Obstructive apnea b) Narcolepsy c) Restless legs syndrome d) Periodic limb movement disorder
Obstructive apnea Explanation: Obstructive apnea causes poor ventilation, poor quality sleep, and daytime sleepiness - at best. At worst, it can contribute to depression, auto- and work-related accidents, cardiac dysrhythmias, and hypertension. Severe apnea can lead to pulmonary hypertension, polycythemia, or cor pulmonale. Periodic limb movement disorder and restless legs syndrome, although distressing and possibly indicative of disease, are not of themselves life threatening. Narcolepsy is not a motor disorder of sleep.

A client comes to the sleep clinic and reports fatigue and daytime sleepiness. Assessment reveals a weight gain of 40 lbs over the last year following smoking cessation and a history of gastroesophageal reflux disease (GERD). The client's wife says that her husband snores so loudly, she cannot remember the last time that she slept well. From what should the nurse suspect this client is suffering? a) Obstructive sleep apnea syndrome b) Narcolepsy c) Restless leg syndrome d) Insomnia
Obstructive sleep apnea syndrome Explanation: Obstructive sleep apnea syndrome is the most commonly diagnosed breathing-related sleep disorder. It is characterized by snoring during sleep and episodes of sleep apnea that can disrupt sleep and contribute to daytime sleepiness.
In which stage of sleep does dreaming occur most frequently? a) Non-Rapid Eye Movement Sleep b) Stage I c) Stage 3 and 4 d) Rapid Eye Movement Sleep
Rapid Eye Movement Sleep Explanation: Most dreaming occurs in REM sleep. Stage 1, 3 and 4 are parts of Non-REM sleep, and dreaming does occur in most stages of sleep.

To treat transient insomnia, it is suggested that good sleep hygiene habits be established. What is an example of sleep hygiene? a) Taking a prescribed dosage of sedatives routinely b) Watching television or reading until falling asleep c) Taking a warm bath at night to promote good hygiene d) Setting up a normal bedtime and awakening time
Setting up a normal bedtime and awakening time Explanation: Good sleep hygiene includes setting normal sleep and wake times to help set the circadian clock, sleeping only as long as needed to feel refreshed, and providing a quiet sleep environment. Each of the other options is not recommended to develop good sleep hygiene.
Sleep disturbances may be caused by multiple factors. Which of the following is not a common contributor to sleep disturbances? a) Prolonged periods of wakefulness b) Length of daylight hours between winter and summer months c) Working the occasional night shift d) Rapid geographical relocation across several time zones
Prolonged periods of wakefulness Explanation: Homeostasis is the coordinated physiological processes that maintain most steady states in an organism. The need for sleep increases as the time awake increases. Prolonged periods of wakefulness result in decreased alertness, increased sleepiness, and greater amounts of slow-wave (NREM stage 4) sleep. But once sleep occurs, homeostasis is accomplished and the accumulated "sleep debt" is replenished. The client awakes feeling rested.

A client tells the nurse that he goes to bed and turns the lights out at 10 PM, but doesn't fall asleep until around 11 PM. The nurse documents this time as which of the following? a) Sleep architecture b) Circadian rhythm c) Sleep efficiency d) Sleep latency
Sleep latency Explanation: Sleep latency is the time period measured from "lights out," or bedtime, to initiation of sleep. Sleep architecture is the pattern of non-rapid eye movement (NREM) and rapid eye movement (REM) that are in about a 90- to 110-minute cycle. Sleep occurs in stages, and the timing of sleep is regulated by circadian rhythms. Sleep efficiency is the ratio of total sleep time to time in bed. Circadian rhythm refers to the pattern that reflects all physiologic and psychological functions fluctuating and repeating itself in a 24-hour cycle.
A client with narcolepsy tells the nurse that it often feels like he is being suffocated when he is falling asleep. He also says, "I get terrified because I can't seem to move." The nurse identifies this as which of the following? a) Hypersomnolence b) Cataplexy c) Sleep paralysis d) Hypnagogic hallucinations
Sleep paralysis Explanation: Sleep paralysis, the inability to move or speak when falling asleep or waking up, is often described as terrifying and is accompanied by a sensation of struggling to move or speak. Although the diaphragm is not involved, patients may also complain of not being able to breathe or feeling suffocated. These episodes are typically brief in duration and usually terminate spontaneously or when the individual is touched.Cataplexy is the bilateral loss of muscle tone triggered by a strong emotion, such as anger or laughter. This muscle atonia can range from subtle (drooping eyelids) to dramatic (buckling knees). Respiratory muscles are not affected. Hypnagogic hallucinations are intense dreamlike images that occur at sleep onset and usually involve the current environment.Hypersomnolence refers to excessive sleepiness.
Which of the following parasomnias occur primarily in children in the Non-REM stage and may result in emotional experiences that are frightening? a) Sleepwalking b) Sleep terrors c) Nightmares d) Confusional arousals
Sleep terrors Explanation: Sleep terrors occur primarily in children, and in the non-REM sleep stage resulting in frightening thoughts. Nightmares occur in the REM sleep stage.
When describing the stages of sleep, which of the following would the nurse identify as the deepest state of sleep? a) Slow-wave sleep b) NREM sleep stage 2 c) REM sleep d) NREM sleep stage 1
Slow-wave sleep Explanation: Slow-wave sleep, or the deepest state of sleep, characterizes stages 3 and 4 of NREM sleep. Light sleep characterizes NREM sleep stage 1 and 2. REM sleep is a deep sleep but the brain is active.
What body function is responsible for the control of the circadian clock with input of light-dark awareness? a) Suprachiasmatic nucleus (SCN) b) Thalamus c) Visual stimulation d) The rotation of the moon
Suprachiasmatic nucleus (SCN) Explanation: The SCN is responsible for the control of the circadian clock through receiving lights-dark input from the retina. Visual stimulation is involved, but the SCN seems to be the control center. While the suprachiasmatic nucleus is part of the hypothalmus, the thalamus is not involved.
A nursing student overhears a sleep clinic doctor say that a patient is diurnal. The student correctly identifies this to mean which of the following? a) The patient remains awake both day and night. b) The patient sleeps both day and night. c) The patient awakes during the day and sleeps during the night. d) The patient awakes at night and sleeps during the day.
The patient awakes during the day and sleeps during the night. Explanation: Most adults are diurnal, meaning that they are awake during the day and asleep at night.
A person with advanced sleep phase syndrome (ASPS) would experience which symptoms? a) Trouble staying awake in the evening and waking up in the morning feeling rested. b) Difficulty falling asleep at night and awakening in the morning. c) Trouble staying awake and falling asleep at inappropriate times. d) Sleeping 10 to 12 hours per day and awakening with feelings of sadness.
Trouble staying awake in the evening and waking up in the morning feeling rested. Explanation: With ASPS a person has trouble staying awake in the evening, goes to bed early and wakes up in the morning feeling rested. Falling asleep at inappropriate times is more related to narcolepsy, and waking up feeling sadness is most related to depression. Trouble going to sleep and trouble waking in the morning is related to delayed sleep phase syndrome.
A nursing instructor is teaching about the importance of sleep for all body systems. What does the instructor identify as types of sleep deprivation? (Select all that apply.) a) Chronic b) Partial c) Indirect d) Complete e) Acute
• Acute • Chronic • Partial • Complete Explanation: Sleep deprivation may be acute or chronic and partial or complete.
Cory, an 18-year-old high school senior, stays up past midnight every night and has to be at school by 7:30 AM the next day. He often feels sleepy until mid-morning yet refuses to go to bed any earlier. An explanation for Cory's disrupted sleep-wake cycle is a) as people get older they tend to fall asleep later and wake earlier naturally. b) adolescents only need 4 to 6 hours of sleep. c) Cory is not motivated to attend his senior year of high school and dreads going. d) circadian changes may be normal in adolescence.
circadian changes may be normal in adolescence. Explanation: As children move through their school years into their teens, total daily sleep time gradually declines from approximately 10 to 7 to 8 hours. Adolescents tend to stay up late into the night and arise late in the morning. They may be difficult to arouse early in the morning and may suffer from excessive daytime sleepiness. These circadian changes may be normal in adolescence.
The pacemaker that regulates sleep-wake cycles in humans and contributes to sleep disorders is ... a) circadian rhythm. b) hippocampus. c) Medulla. d) caudate nucleus and pineal glands.
circadian rhythm. Explanation: The circadian rhythm is a pacemaker or biological clock that regulates the daily patterning of sleep. In mammals this structure is the suprachiasmic nucleus located in the hypothalamus. The circadian pacemaker stimulates changes in the daily patterns of sleep and wake that are endogenous (stimulated internally) to the organism.
A client complains of sleepiness during the day and occasional slight memory lapses. During the assessment, his wife states she is bothered by his snoring, especially when he is sleeping on his back. She often rolls him over in his sleep. The nurse suspects the client has ... a) narcolepsy b) parasomnia c) sleep deprivation d) obstructive sleep apnea syndrome
obstructive sleep apnea syndrome Explanation: Clients with OSA experience sleep disruption and excessive daytime sleepiness. They typically snore loudly and gasp or choke during sleep, which is more severe when they lie supine. They may be unaware that they have apnea or hypopnea or that they snore during sleep. They are at risk for lapses in memory, slowed reaction time, and falling asleep while working, operating machinery, or driving a motor vehicle.

Since the 1960s, benzodiazepines have been prescribed commonly to promote sleep. However, a newer classification of drugs, the nonbenzodiazepine-benzodiazepine agonists, including zolpidem (Ambien) and zaleplon (Sonata), are becoming more commonly used. One major advantage of the nonbenzodiazepine-benzodiazepine agonists is a) their effects may last into the next day. b) they also contain antihistamines, which aid in sedation and drowsiness. c) they are less likely to produce tolerance or hangover effects. d) they also help to reduce general anxiety levels.
they are less likely to produce tolerance or hangover effects. Explanation: These drugs act more selectively on GABA receptors than the benzodiazepines to promote sleep. They are less likely to produce tolerance or hangover effects than the benzodiazepines.
