Q

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) 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.

Q

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

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.

Q

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

A

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.

recommended in this type of therapy?
A) Use the bedroom for sleep and sex only.
B) Use the bedroom for reading and eating.
C) Go to bed at the same time every night.
D) Sleep alone with minimal coverings.

A

A) Use the bedroom for sleep and sex only.

Stimulus control involves using the bedroom for sleep and sex only. If not asleep within 15 to 20 minutes, the person
should leave the room and return only when he or she feels sleepy. Getting up at the same time every day is also recommended.

18
Q

A client is diagnosed with narcolepsy. Which of the following is a characteristic of this disorder?
A) Waking during sleep
B) Restless leg syndrome
C) Uncontrollable desire to sleep
D) Decrease in the amount or quality of sleep

A

C) Uncontrollable desire to sleep

Narcolepsy is a condition characterized by an uncontrollable desire to sleep. Narcolepsy is considered a neurologic
disorder

19
Q

A client with a sleep disorder experiences cataplexy. Which is a feature of this condition?
A) Irresistible urge to sleep, regardless of the type of activity in which the client is engaged
B) Sudden loss of motor tone that may cause the person to fall asleep; usually experienced during a period of strong
emotion
C) Nightmare or vivid hallucinations experienced during sleep time
D) Skeletal paralysis that occurs during the transition from wakefulness to sleep

A

Sudden loss of motor tone that may cause the person to fall asleep; usually experienced during a period of strong
emotion

Cataplexy is the sudden loss of motor tone that may cause the person to fall asleep; this is usually experienced during a
period of strong emotion. Sleep attacks are irresistible urges to sleep, regardless of the type of activity in which the client
is engaged. Hypnagogic hallucinations involve nightmares or vivid hallucinations. In sleep-onset REM periods, during a sleep attack, the person moves directly into REM sleep. Sleep paralysis is skeletal paralysis that occurs during the
transition from wakefulness to sleep.

20
Q

What is the rationale for using CPAP to treat sleep apnea?
A) Positive air pressure holds the airway open.
B) Negative air pressure holds the airway closed.
C) Delivery of oxygen facilitates respiratory effort.
D) Alternating waves of air stimulate breathing.

A

A) Positive air pressure holds the airway open.

Continuous positive airway pressure (CPAP) is used to treat sleep apnea. The device, worn at night, delivers positive air
pressure through a facemask to hold the airway open

21
Q
The parents of a boy 10 years of age are worried about his sleepwalking (somnambulism). What topic should the nurse
discuss with the parents?
A) Sleep deprivation
B) Privacy
C) Schoolwork
D) Safety
A

D) Safety

Somnambulism (sleepwalking) is a parasomnia, a pattern of waking behaviour that appears during sleep. It is more commonly seen in children and is commonly outgrown before adulthood. Safety and prevention of injury are paramount concerns

22
Q

What independent nursing action can be used to facilitate sleep in hospitalized clients who are on bedrest?
A) Administering prescribed sleep medications
B) Changing the bed with fresh linens
C) Encouraging naps during the daytime
D) Giving a back massage

A

D) Giving a back massage

Simple interventions, such as offering a back massage, can promote comfort and sleep in hospitalized clients on bedrest.

23
Q

A sedative-hypnotic has been prescribed to help a client sleep. What should the nurse teach the client about this
medication?
A) It should be taken every night for several months
B) It is useful for sleep but is better taken with alcohol
C) It loses its effectiveness after one or two weeks
D) It should be taken in the morning for long-term effects

A

C) It loses its effectiveness after one or two weeks

Although most sedative-hypnotics provide several nights of excellent sleep, the medication often loses its effect after
one or two weeks. Caution the client not to increase the dose or take the drug with alcohol to try to increase effect.

24
Q
What is the most common method for ordering sleep medications?
A) Stat
B) p.r.n
C) Single order
D) Daily dose
A

B) p.r.n

Sleep medications are often ordered on a p.r.n. (as needed) basis. These medications should be administered only when
indicated, and always with the full knowledge of their limitations.

25
Q
What condition have studies confirmed occurs when adults and children do not get recommended hours of sleep at
night?
A) Obesity
B) Anxiety
C) Diabetes
D) Hypertension
A

A) Obesity

The fact that children and adults are getting less sleep has been implicated as a contributing factor to the obesity epidemic in the United States (CDC, 2008, Goldsmith, 2007). Various studies confirm that adults and children who slept
less than their recommended hours per night were more likely to be overweight. This sleep-weight link is possibly
related to two hormones: leptin and ghrelin. Leptin signals the brain to stop eating, whereas ghrelin promotes continued
eating. Research suggests that sleep deprivation lowers leptin levels and elevates ghrelin levels, thus increasing one’s
appetite.

26
Q
Which drug normalizes sleep cycles by enabling the body’s supply of melatonin to naturally promote sleep?
A) Flurazepam (Dalmane)
B) Temazepam (Restoril)
C) Eszopiclone (Lunesta)
D) Ramelteon (Rozerem)
A

D) Ramelteon (Rozerem)

The most recently approved sleep medication is Ramelteon (Rozerem). This drug is classified as a melatonin receptor agonist and it normalizes sleep cycles by enabling the body’s supply of melatonin to naturally promote sleep
(Goldsmith, 2007).

27
Q

Which expected outcome demonstrates the effectiveness of a plan of care to promote rest and sleep?
A) Verbalizes inability to sleep without medications
B) Continues to read in bed for hours each night
C) Identifies factors that interfere with normal sleep pattern
D) Reports minimal improvement in quality of rest and sleep

A

C) Identifies factors that interfere with normal sleep pattern

The nurse evaluates the effectiveness of the plan of care to promote rest and sleep by evaluating if the client has met the
expected outcomes of the plan. If the client is able to identify factors that interfere with normal sleep patterns, this illustrates achievement of one expected outcome

28
Q

A nurse is caring for a client who has been diagnosed with insomnia. What nursing intervention would help the nurse
relieve the client’s condition?
A) Maintain a calm and quiet environment free from noise.
B) Administer sedatives as prescribed by the physician.
C) Motivate the client to sleep because it may affect his health.
D) Engage the client in some diversional activities.

A

A) Maintain a calm and quiet environment free from noise.

Maintaining a calm and quiet environment is the most appropriate nursing activity to relieve insomnia. Motivating the client to sleep by telling him that it may affect his health may cause anxiety in the client. Engaging the client in diversional activities at bedtime may increase sleeplessness. Sedatives can be administered as prescribed, but they
should be used as last resort. These activities may not relieve insomnia in the client.

29
Q
A nurse is caring for a client diagnosed with sleep apnea. What should the nurse do in order to promote sleep in the
client?
A) Encourage the client to lose weight.
B) Avoid sedatives for sleeping.
C) Encourage deep breathing exercises.
D) Provide good ventilation in the room.
A

B) Avoid sedatives for sleeping.

The nurse should avoid sedatives in the client because sedatives may depress respiration. The client with sleep apnea
already has decreased ventilation and low blood oxygenation; the condition may become worse if the respiration is further depressed by sedatives. Losing weight is a long-term measure and is not applicable in this case. Encouraging deep breathing exercises and providing good ventilation may help the client, but they are secondary measures

30
Q

A nurse is caring for a client who complains about sleep apnea. Which of the following delivery devices should the
nurse use to administer oxygen to this client?
A) Nasal catheter
B) Oxygen tent
C) Transtracheal oxygen
D) CPAP mask

A

D) CPAP mask

The nurse should use a CPAP mask for a client with complaints of sleep apnea. A CPAP mask maintains positive pressure within the airway throughout the respiratory cycle. Clients generally wear this type of mask at night to maintain
oxygenation when they experience sleep apnea. A nasal catheter is a tube for delivering oxygen that is inserted through the nose into the posterior nasal pharynx. It is used for clients who tend to breathe through the mouth or experience claustrophobia when a mask covers their face. An oxygen tent is a clear plastic enclosure that provides cooled, humidified oxygen, which is used for active toddlers. Transtracheal oxygen is a hollow tube inserted within the trachea to deliver oxygen to clients who require long-term oxygen therapy.

31
Q

. Which of the following guidelines does the nurse apply to discussion of sleep patterns with older adult clients?
A) Circadian rhythms become more prominent as clients age.
B) The amount of stage 4 sleep increases as clients age.
C) Total sleep time decreases as the clients age.
D) Older clients fall asleep more quickly than younger ones

A

C) Total sleep time decreases as the clients age

As people age, the amount of stage 4 sleep decreases significantly. Sleeping patterns may become polyphasic, with a
shorter nocturnal period plus daytime naps.

32
Q

A client has sought care because of insomnia that has been increasing in severity and frequency in recent months. What
questions should the nurse include in an assessment of this client’s health problem? Select all that apply.
A) “Do you have a family history of sleep disturbances?”
B) “Do you smoke?”
C) “What medications are you currently taking?”
D) “Do you have a consistent routine around getting ready for bed and going to bed?”
E) “How would you characterize your mood lately?”

A

B) “Do you smoke?”
C) “What medications are you currently taking?”
D) “Do you have a consistent routine around getting ready for bed and going to bed?”
E) “How would you characterize your mood lately?”

Sleep is a multifaceted phenomenon that is affected by many variables. Among these are cigarette smoking,
medications, sleep routines, and mood; the nurse should assess each of these areas. Sleep problems do not normally have a genetic basis.

33
Q
Time period Activity
0600-0900 awake
0900-1100 sleep
1100-1300 awake
1300-1600 sleep
1600-1900 awake
1900-2200 sleep
2200-2400 awake
2400-0600 sleep

The best statement by the nurse is:
A) “Your infant requires more time asleep during the day hours.”
B) “You need to awaken your infant during the 2400 to 0600 time period.”
C) “Your infant is obtaining the average hours of sleep per day for an infant.”
D) “Your infant is actually obtaining too little sleep for one day.”

A

C) “Your infant is obtaining the average hours of sleep per day for an infant.”

Infants usually require 14 to 20 hours of sleep per day. This infant is obtaining 14 hours of sleep each day

34
Q

The nurse manager in an acute care facility has received client evaluations in which the clients have complained about excessive noise that interfered with their rest. The nurse manager and nursing staff plan to do the following. Which activity will most assist clients in obtaining rest?
A) Post signs for quiet and turn down hall lights during formal quiet times.
B) Ensure clients are offered prescribed sleeping medications at bedtime.
C) Provide a small carbohydrate snack or juice prior to hours of sleep.
D) Adjust the temperature of the room to 74 degrees and provide a blanket.

A

A) Post signs for quiet and turn down hall lights during formal quiet times.

All of the options may be helpful in promoting rest. However, the client complaints are about excessive noise, and
posting signs for quiet and turning down hall lights during formal quiet times is the only option that directly addresses noise. Also, some clients cannot rest if the room temperature is not to their liking. The room temperature needs to be adjusted to client preference

35
Q

The client is a male who states his wife complains that his snoring awakens her at night. The spouse is present. To obtain further data, the nurse asks the spouse what?
A) “How loud is his snoring?”
B) “Is there silence after snoring which then is followed with a snort?”
C) “How long does he snore each night?”
D) “How often are you awakened at night due to his loud snoring?”

A

B) “Is there silence after snoring which then is followed with a snort?”

Snoring that is followed by silence and then a snort may be a sign of obstructive apnea. Snoring is not considered a
sleeping disorder and is often more disturbing to the sleep partner.
