Chapter 34 Flashcards
Which natural chemical does the body produce at night to decrease wakefulness and promote sleep? A) Melatonin B) Serotonin C) Endorphins D) Dopamine
A) Melatonin
Melatonin is a natural chemical produced at night that decreases wakefulness and promotes sleep
A client reports that her naps after lunch often stretch to three hours in length and that she has great difficulty rousing
herself after a nap. This condition is best termed as which of the following?
A) Hypersomnia
B) Insomnia
C) Parasomnia
D) Sleep apnea
A) Hypersomnia
Hypersomnia is a condition characterized by excessive sleep, particularly during the day. Insomnia is characterized by difficulty falling asleep, intermittent sleep, or early awakening from sleep. Parasomnias are patterns of waking behavior that appear during sleep. Sleep apnea is a condition in which a person experiences the absence of breathing, or diminished breathing efforts, during sleep (between snoring intervals).
A client in his 40s has asked the nurse how much sleep he should be getting in order to maximize his health and wellbeing. How should the nurse respond?
A) “Most adults need between seven and nine hours, but everyone is different.”
B) “It’s important to get a minimum of eight hours sleep each night.”
C) “More sleep equals better health, so the more sleep you can fit into your schedule, the better.”
D) “Sleep needs depend a lot on age, and at your age, six to seven hours usually suffice.”
A) “Most adults need between seven and nine hours, but everyone is different.”
Sleep needs and routines are highly individual, but most adults require between seven and nine hours of sleep
Which of the following clients likely faces a risk for the nursing diagnosis of Disturbed Sleep Pattern: Difficulty
Remaining Asleep?
A) A client who receives IV antibiotics every three hours
B) A client whose opioid analgesics result in central nervous system depression
C) A client who is receiving corticosteroids that make her feel restless and agitated
D) A client whose physical therapy has been scheduled in the late evening
A) A client who receives IV antibiotics every three hours
A client who requires medications throughout the night is likely to experience the frequent awakenings associated with
Disturbed Sleep Pattern: Difficulty Remaining Asleep. Drowsiness or agitation as a result of medications may affect
sleep, but are less likely to result in mid-sleep awakenings. A client who performs physical activity prior to bedtime may
have difficulty falling asleep.
Which group of terms best describes sleep?
A) Decreased state of activity, refreshed
B) Altered consciousness, relative inactivity
C) Comatose, immobility
D) Alert, responsive
B) Altered consciousness, relative inactivity
Sleep is a state of rest accompanied by altered consciousness and relative inactivity. Rest is a condition in which the
body is in a decreased state of activity
An individual awakens from a sound sleep in the middle of the night because of abdominal pain. Why does this happen?
A) Stimuli from peripheral organs to the RAS
B) Stimuli to the wake center in the cerebral cortex
C) Messages from chemoreceptors to the brain
D) Messages from baroreceptors to the spinal cord
A) Stimuli from peripheral organs to the RAS
The reticular activating system (RAS) facilitates reflex and voluntary movements as well as cortical activities related to a state of alertness. Wakefulness occurs when the RAS experiences stimuli (including pain) from peripheral organs and cells.
A nurse is caring for a client who is sleeping for abnormally long periods of time. This condition may be caused by
injury to which of the following body structures?
A) Spinal cord
B) Pancreas
C) Hypothalamus
D) Thyroid
C) Hypothalamus
The hypothalamus has control centers for several involuntary activities of the body, one of which concerns sleeping and
waking. Injury to the hypothalamus may cause a person to sleep for abnormally long periods.
What name is given to the rhythmic biologic clock that exists in humans? A) Sleep-wake cycle B) Alert-unaware process C) Circadian rhythm D) Yo-yo theory
C) Circadian rhythm
Rhythmic biologic clocks are known to exist in plants, animals, and humans. Circadian rhythms complete a full cycle every 24 hours and in humans affect heart rate, blood pressure, body temperature, hormone secretions, and metabolism,
as well as performance and mood.
A nurse working the night shift assesses a client’s vital signs at 4 a.m. (0340). What would be the expected findings, based on knowledge of NREM sleep? A) Decreased TPR and BP B) Increased TPR and BP C) No change from daytime readings D) Highly individualized, cannot predict
A) Decreased TPR and BP
Throughout the stages of NREM sleep, the parasympathetic nervous system dominates; decreases in temperature, pulse, respirations, and blood pressure occur.
A nurse educates a young couple on putting their newborn on his back to sleep. What is the rationale for this
information?
A) Prone position increases the risk for sudden infant death syndrome.
B) Prone position decreases the risk for sudden infant death syndrome.
C) Supine position may alter the size and shape of the infant’s head.
D) Supine position makes changing diapers and feeding difficult.
A) Prone position increases the risk for sudden infant death syndrome.
Newborns sleep an average of 16 out of every 24 hours. It is important to teach parents to position an infant on the back.
Sleeping in the prone position increases the risk for sudden infant death syndrome (SIDS).
Based on the circadian cycle, the body prepares for sleep at night by decreasing the body temperature and releasing which chemical? A) Neonephrine B) Seratonin C) Melatonin D) Dopamine
C) Melatonin
Based on the circadian cycle, the body prepares for sleep at night by decreasing the body temperature and releasing
melatonin (a natural chemical produced at night that decreases wakefulness and promotes sleep)
A middle-age adult man has just started an exercise program. What would the nurse teach him about timing of exercise
and sleep?
A) Exercising immediately before bedtime enhances ability to sleep
B) Exercising within two hours of bedtime can hinder ability to sleep
C) The time of day does not matter; exercise facilitates sleep
D) The fatigue from exercise may be a hindrance to sleep
B) Exercising within two hours of bedtime can hinder ability to sleep
Moderate exercise is a healthy way to promote sleep, but exercise that occurs within a two-hour interval before normal
bedtime can hinder sleep
Which medication is least likely to affect sleep quality? A) Diuretic B) Steroid C) Antidepressant D) Ambien
D) Ambien
Sleep quality is influenced by drugs. Drugs that decrease sleep include diuretics, steroids, and antidepressants. Ambien
and chloral hydrate appear to influence the quality of sleep least and promote normal sleep.
Which individual is likely to require more hours of sleep? A) a person 75 years of age B) a person 43 years of age C) a person 25 years of age D) a person 15 years of age
D) a person 15 years of age
Despite individual variations, growing children, especially adolescents who are in a tremendous growth period, require from 10 to 14 hours of sleep per night. This is in comparison with the accepted standard for adults, which is 8 hours.
Older adults often require less sleep.
A client’s bed partner reports the client often has irregular snoring and silence followed by a snort. Does this warrant
further assessment?
A) No, snoring has varied patterns
B) No, this is a description of normal snoring
C) Yes, this is an indicator of obstructive apnea
D) Yes, the bed partner is unable to sleep at night
C) Yes, this is an indicator of obstructive apnea
Snoring is caused by an obstruction to airflow through the nose and mouth. When snoring changes from the
characteristic sawing wood sound to a more irregular silence followed by a snort, this indicates obstructive apnea.
