Sleep Rest
VCS When You Have to Be Right: Rest and Sleep
Objectives
Identify variables that influence rest and sleep.
Describe age-related differences in the sleep cycle.
Describe nursing strategies to promote sleep and rest.
Sleep Cycle
The sleep cycle consists of four consecutive stages of non-rapid eye movement (NREM) sleep, which are reversed before entering REM sleep.
Stages of NREM:
The person returns from Stage IV to III to II.
After reaching the end of Stage II, REM sleep is entered instead of returning to Stage I.
Re-entering NREM starts at Stage II then moves through stages III and IV.
Single Normal Sleep Cycle
Wakefulness transitions into NREM and then REM:
NREM stages include:
Stage I
Stage II
Stage III
Stage IV
After completing cycle, the pattern starts over with wakefulness.
Stages of Sleep
Non-Rapid Eye Movement (NREM) Sleep:
Four stages characterized as follows:
Stages I and II: Light sleep (5% to 50% of total sleep time)
Stages III and IV: Deep sleep states (delta sleep, approx. 10% of total sleep time)
Rapid Eye Movement (REM) Sleep:
Represents about 20% to 25% of total sleep time.
Physiological changes occur, including increased pulse, respiratory rate, blood pressure, metabolic rate, and body temperature; skeletal muscle tone and reflexes are depressed during this stage.
Factors Affecting Sleep
Various factors can impact sleep:
Developmental considerations
Lifestyle and habits
Environmental factors
Psychological stress
Illnesses
Medications
Developmental Considerations
The amount of sleep needed varies by age group:
Newborns, infants, toddlers
Preschoolers
School-aged children
Adolescents
Young adults and adults
Elderly adults
Review strategies to promote sleep and rest across these age groups.
Illnesses Associated with Chronic Sleep Disturbances
Chronic sleep disturbances are often linked to:
Depression
Increased risk of obesity
Hypertension
Diabetes
Heart attacks
Strokes
Sleep Disorders
Dyssomnias: Characterized by insomnia or excessive sleepiness.
Parasomnias: Involves patterns of waking behavior appearing during sleep.
Types of Dyssomnias
Includes several specific conditions:
Insomnia
Hypersomnia
Narcolepsy
Sleep apnea
Restless leg syndrome
Sleep deprivation
Obstructive Sleep Apnea
A physical condition characterized by:
Normal unoccluded airway versus an occluded airway (tongue, soft palate, uvula).
Types of Parasomnias
Disorders include:
Somnambulism
REM behavior disorder (RBD)
Sleep terrors
Nightmares
Bruxism
Enuresis
Sleep-related eating disorder
Obtaining a Sleep History
Essential questions to ask include:
Nature and cause of the sleep problem
Related signs and symptoms
Duration and frequency of the problem
Impact of the problem on daily living
Severity of the problem and treatment options
Coping mechanisms and treatment success
Sleep Characteristics to Assess
Indications to observe and assess:
Restlessness
Sleep postures
Sleep activities
Snoring
Leg jerking
Information Recorded in a Sleep Diary
Important details to include:
Time patient retires
Time attempting to fall asleep
Approximate time patient falls asleep
Times of awakening during the night
Morning awakening time
Presence of stressors affecting sleep
Food, drink, or medication affecting sleep
Physical and mental activities prior to bedtime
Worries or anxieties impacting sleep
Key Findings of Physical Assessment
Aspects to look for:
Energy level
Facial characteristics
Behavioral attributes
Physical data suggesting sleep problems
Common Etiologies for Nursing Diagnoses
Factors leading to sleep issues include:
Physical/emotional discomfort or pain
Changes in bedtime rituals or sleeping environment
Disruption of circadian rhythm
Pre-bedtime exercise and diet
Drug dependency and withdrawal
Symptoms of physical illness
Nursing Interventions to Promote Sleep
Strategies to enhance sleep include:
Create a restful environment
Establish bedtime rituals
Offer appropriate snacks and beverages
Encourage relaxation and comfort
Respect normal sleep-wake patterns
Schedule nursing care to minimize disturbances
Employ medication when necessary
Educate about the importance of rest and sleep
