ECPI 2020: NUR 164: CHAPTER 34: REST & SLEEP
A nurse caring for patients in a busy hospital environment should implement which recommendation to promote sleep? A) Keep the room light dimmed during the day. B) Keep the room cool. C) Keep the door of the room open. D) Offer a sleep aid medication to patients on a regular basis
B) Keep the room cool.
A nurse is performing a sleep assessment on a patient being treated for a sleep disorder. During the assessment, the patient falls asleep in the middle of a conversation. The nurse would suspect which disorder? A) Circadian rhythm sleep-wake disorder B) Narcolepsy C) Enuresis D) Sleep apnea
B) Narcolepsy
Barbiturates, amphetamines, and antidepressants increase REM sleep. A. True B. False
B. False Barbiturates, amphetamines, and antidepressants decrease REM sleep.
In which stage of NREM sleep does the person fall into a stage of sleep but can be aroused with relative ease? A. Stage I B. Stage II C. Stage III D. Stage IV
B. Stage II In stage II of NREM sleep, the person falls into a stage of sleep but can be aroused with ease. In stage I, the person is in a transitional stage between wakefulness and sleep. In stages III and IV, the depth of sleep increases, and arousal becomes increasing difficult.
Which of the following snacks is an appropriate bedtime snack to promote sleep in a patient? A. Candy B. Toast C. Lunchmeat D. Cheese
B. Toast Because carbohydrates seem to promote sleep, there appears to be justification for offering a snack or beverage high in carbohydrates (such as toast or crackers) before bedtime. Candy, lunchmeat, and cheese do not contain carbohydrates.
Stages Of NRM Sleep: Stage IV:
- The person reaches the greatest depth of sleep, which is called delta sleep. - Arousal from sleep is difficult. Physiologic changes in the body include the following: - Slow brain waves are recorded on an EEG - Pulse and respiratory rates decrease - Blood pressure decreases - Muscles are relaxes - Metabolism slows and the body temperature is low. - This constitutes about 10% of sleep
Information Recorded in a Sleep Diary:
- Time patient retires - Time patient tries to fall asleep - Approximate time patient falls asleep - Time of any awakening during the night and resumption of sleep - Time of awakening in morning - Presence of any stressors affecting sleep - Record of food, drink, or medication affecting sleep - Record of physical and mental activities - Record of activities performed 2 to 3 hours before bedtime - Presence of worries or anxieties affecting sleep
Factors Affecting Sleep: Culture:
- A person's cultural beliefs and practices can influence rest and sleep. A - Although developmental stages are similar, children's bedtime rituals, sleeping position and place, and pattern of sleep may vary based on culture. - Methods to enhance or foster sleep may also be culturally influenced. - A cultural orientation toward privacy and quiet makes sleep difficult in a busy special care unit. - Sensitivity to a patient's culture must be included in the plan of care for preparing the patient for an evening's sleep.
Factors Affecting Sleep: Illness:
- A physiologic as well as a psychological stressor, influences sleep. Certain illnesses are more closely related to sleep disturbances than others. - For example: Gastric secretions increase during REM sleep. Many people with gastroesophageal reflux disease (GERD) awaken at night with heartburn or pain. They find that using antacids to neutralize stomach acidity often relieves discomfort and promotes sleep. - The pain associated with coronary artery disease and myocardial infarction is more likely with REM sleep. - Epilepsy seizures are most likely to occur during NREM sleep and appear to be depressed by REM sleep. - Liver failure and encephalitis tend to cause a reversal in day-night sleeping habits. - Hypothyroidism tends to decrease the amount of NREM sleep, especially stages II and IV, while hyperthyroidism may result in difficulty falling asleep. - End-stage renal disease (ESRD) disrupts nocturnal sleep and leads to excessive daytime sleepiness. - Patients with ESRD who receive dialysis also have a higher incidence of RLS (discussed later in the chapter), which possibly is related to the iron deficiency common in ESRD.
Circadian Rhythm Sleep-Wake Disorders:
- Characterized by a chronic or recurrent pattern of sleep-wake rhythm disruption primarily caused by an alteration in the internal circadian timing system or misalignment between the internal circadian rhythm and the sleep-wake schedule desired or required; a sleep-wake disturbance (e.g., insomnia or excessive sleepiness); and associated distress or impairment, lasting for a period of at least 3 months (except for jet lag disorder) - Treatment for circadian rhythm sleep-wake disorders varies based on the type of disorder and the degree to which it affects a person. Behavior therapy includes maintaining regular sleep-wake times, avoiding naps, keeping to a regular exercise routine, and avoiding caffeine, nicotine, and stimulating activities within several hours of bedtime - Light therapy helps ease the transition to a new schedule or time zone. It involves exposing the patient's eyes to an artificial bright light that simulates sunlight for a specific and regular amount of time during the time the person should be awake - Chronotherapy requires a commitment on the part of the patient to act over a period of weeks to progressively advance or delay the time of sleep for 1 to 2 hours per day. Over time, this results in a shift of the sleep-wake cycle
Sleep Disorders: Insomnia:
- Characterized by difficulty falling asleep, intermittent sleep or difficulty maintaining sleep, despite adequate opportunity and circumstances to sleep. - As many as 30 to 35 percent of adults in the United States complain of insomnia. - People with a history of depression are more likely to experience insomnia. - Many cases of insomnia are related to disruptions in circadian rhythms. - Insomnia may be short-term or chronic in nature.
Central disorders of hypersomnolence: Idiopathic hypersomnia:
- Characterized by excessive sleep, particularly during the day. - A person may fall asleep for intervals during work, while eating, or even during conversations. - These naps do not usually relieve their symptoms. - When they awake, they are often disoriented, irritated, restless, and have slower speech and thinking processes. - Some people may have a genetic predisposition to hypersomnia. - It appears most often in adolescents and young adults. - Although not usually life threatening, hypersomnia can have some serious consequences, such as motor vehicle accidents that occur because of drowsiness or falling asleep while driving. These attacks may occur indefinitely
Characteristics of Circadian Rhythm Sleep -Wake Disorders:
- Chronic or recurrent pattern of sleep-wake rhythm disruption Primary causes: - An alteration in the internal circadian timing system or misalignment between the internal circadian rhythm and the sleep-wake schedule desired or required - A sleep-wake disturbance (e.g., insomnia or excessive sleepiness) - Associated distress or impairment, lasting for a period of at least 3 months (except for jet lag disorder).
Stages Of Sleep: Non-rapid eye movement (NREM):
- Comprises about 75% of total sleep time, consists of four stages. Stages I and II, consuming about 5% and 50% of a person's sleep time - Are light-sleep states. - During these stages, the person can be aroused with relative ease. - Stages III and IV, each representing about 10% of total sleep time, are deep-sleep states, termed delta sleep or slow-wave sleep. - The arousal threshold (intensity of stimulus required to awaken) is usually greatest in stage 4 NREM. Throughout the stages of NREM sleep, the parasympathetic nervous system dominates, and decreases in pulse, respiratory rate, blood pressure, metabolic rate, and body temperature are observed.
Key Findings of Physical Assessment:
- Energy level - Facial characteristics - Behavioral characteristics - Physical data suggestive of sleep problems
REM Sleep Characteristics:
- Eyes dart back and forth quickly. - Small muscle twitching, such as on the face - Large muscle immobility, resembling paralysis - Respirations irregular; sometimes interspersed with apnea - Rapid or irregular pulse - Blood pressure increases or fluctuates - Increase in gastric secretions - Metabolism increases; body temperature increases - Encephalogram tracings active - REM sleep enters from stage II of NREM sleep and reenters NREM sleep at stage II: arousal from sleep difficult
Factors Affecting Sleep: Medications:
- Health care practitioners must also take into account the effect that drugs used to treat medical or psychological disorders have on sleep. - Drugs that decrease REM sleep include barbiturates, amphetamines, and antidepressants. - Diuretics, antiparkinsonian drugs, some antidepressants and antihypertensives, steroids, decongestants, caffeine, and asthma medications are seen as additional common causes of sleep problems. - Chronotherapeutics is a growing field of study that involves the strategic use of time in the administration of medicine. Researchers have determined that certain treatments for disease are more effective when circadian rhythms are taken into account. - For example, a larger midafternoon dose of asthma medication may be more effective in preventing attacks that commonly occur at night during sleep. - The timing of antihypertensive medication administration may need to be adjusted to provide peak protection during early-morning hours, when heart attacks are more common. - Cancer chemotherapy appears to be less toxic when administered at certain times of the day. - Paying attention to biologic rhythms may influence drug tolerance and medication effectiveness, and reduce adverse effects, including those related to rest and sleep.
Rapid eye movement (REM):
- It is more difficult to arouse a person during this - consumes 20% to 25% of a person's nightly sleep time - People who are awakened during the REM state almost always report that they have been dreaming. They can usually vividly recall their dreams even if they were absurd or have no sensible meaning for them. Everyone dreams. - the pulse, respiratory rate, blood pressure, metabolic rate, and body temperature increase, whereas general skeletal muscle tone and deep tendon reflexes are depressed. REM sleep is believed to be essential to mental and emotional equilibrium and to play a role in learning, memory, and adaptation. - Person who is deprived of REM sleep for several nights generally will spend more time in REM sleep on successive nights
Factors Affecting Sleep: Environmental factors:
- Most people sleep best in their usual home environments. - Sleeping in a strange or new environment tends to influence both REM and NREM sleep. - People accustomed to sleeping in a noisy environment, such as a busy large city, actually have a hard time falling asleep in an area that is extremely quiet. - By turning on a radio or other noise, the person may actually be able to rest in the new environment. Likewise, if a patient is accustomed to sleeping in a quiet environment, a room next to a high-traffic area, such as the nurse's desk, may not be the best place for this patient to rest.
Obtaining a Sleep History:
- Nature of problem - Cause of problem - Related signs and symptoms - When the problem began and how often it occurs - How the problem affects everyday living - Severity of the problem and how it can be treated - How the patient is coping with the problem and success of treatments attempted
Factors Affecting Sleep: Lifestyle and habits:
- People working a shift other than the day shift must reorganize their priorities, or sleep difficulties may occur. - 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). - Working the night shift disrupts this natural process and can result in loss of sleep and other adverse effects. - Developing a sleep pattern is especially difficult if the work shift changes periodically. - Nurses and others who work long hours and varying shifts have difficulty finding time to exercise, which can promote weight gain. - The duration and quality of sleep can be affected by watching some types of television shows, participating in stimulating outside activities, and taking part in activity or exercise within 3 hours of the person's normal bedtime. - A person's ability to relax from work-related pressures and to put aside home stresses are also important factors in the ability to fall asleep.
Common Etiologies for Nursing Diagnoses:
- Physical or emotional discomfort or pain - Changes in bedtime rituals or sleep environment - Disruption of circadian rhythm - Exercise and diet before sleep - Drug dependency and withdrawal - Symptoms of physical illness
Nursing Interventions to Promote Sleep:
- Prepare a restful environment. - Promote bedtime rituals. - Offer appropriate bedtime snacks and beverages. - Promote relaxation and comfort. - Respect normal sleep-wake patterns. - Schedule nursing care to avoid disturbances. - Use medications to produce sleep. - Teach about rest and sleep.
Functions of Rest and Sleep:
- Rest refers to a condition in which the body is in a decreased state of activity, with the consequent feeling of being refreshed. - Sleep is a state of rest accompanied by altered consciousness and relative inactivity. - Sleep is part of what is called the sleep-wake cycle. Wakefulness is a time of mental activity and energy expenditure. - Sleep is a period of inactivity and restoration of mental and physical function.
Sleep Related Movement Disorders: Restless Legs Syndrome (RLS):
- Restless legs syndrome (RLS), also known as Willis- Ekbom disease (WED), is a common sleep-related movement disorder that affects up to 15% of the population, most often middle-aged and older adults. - People with restless legs syndrome (RLS) cannot lie still and report unpleasant creeping, crawling, or tingling sensations in the legs. - Nonpharmacologic treatments
Sleep Characteristics To Assess:
- Restlessness - Sleep postures - Sleep activities - Snoring - Leg jerking
Stages Of NRM Sleep: Stage III:
- The depth of sleep increases, and arousal becomes increasingly difficult. - This stage composes about 10% of sleep.
Stages Of NRM Sleep: Stage II:
- The person falls into a stage of sleep. - The person can be aroused with relative ease. - This stage constitutes 50% to 55% of sleep.
Stages Of NRM Sleep: Stage I:
- The person is in a transitional stage between wakefulness and sleep. - The person is in a relaxed state but still somewhat aware of the surroundings. - Involuntary muscle jerking may occur and waken the person. - The stage normally lasts only minutes. - The person can be aroused easily. - This stage constitutes only about 5% of total sleep.
Sleep Cycle Stages:
- The person passes consecutively through four stages of NREM sleep. - The pattern is then reversed. - Return from stage IV to III to II - Enter REM sleep instead of re-entering stage I - The person re-enters NREM sleep at stage II and moves on to III and IV.
Factors Affecting Sleep: Developmental Considerations:
- Variations in sleep patterns are related to age - Routine assessment of sleepiness or short sleep patterns in children is a first step in identifying the existence of a sleep problem and factors interfering with a child's sleep. - With a growing body of evidence linking inadequate sleep with obesity and other health concerns in children, health care practitioners must ask about patterns of sleep and sleep habits in children and discuss these issues with parents. - A majority of people ages 65 and older report difficulty falling asleep, early awakening or waking frequently during the night, napping, or not feeling rested after a night's sleep. - Older adults often need more time to fall asleep and are less able to cope with changes in their usual sleep patterns compared to younger people. - Many older adults nap during the day, which often results in sleeping fewer hours at night. - Chronic illnesses in older adults may also affect their sleep patterns. - For instance, many older men have enlargement of the prostate gland, which may cause them to awaken throughout the night to use the bathroom.
