Study Notes
Learning Outcomes
- Explain physiology and functions of sleep.
- Identify NREM (Non-Rapid Eye Movement) and REM (Rapid Eye Movement) sleep characteristics.
- Describe variations in sleep patterns across the lifespan.
- Identify factors influencing sleep.
- Discuss common sleep disorders.
- Outline components of a sleep pattern assessment.
- Develop nursing diagnoses, outcomes, and interventions for sleep issues.
- Identify interventions that promote better sleep.
Physiology of Sleep
- Sleep involves cycles alternating with wakefulness, influencing physiological functions and behaviors.
- The Reticular Activating System (RAS) in the anterior brainstem regulates alertness and wakefulness.
Circadian Rhythms
- Biological rhythms affect plants, animals, and humans, synchronized with environmental cues like light.
- Circadian rhythms follow a 24-hour cycle, affecting sleep-wake cycles, body temperature, and blood pressure.
- Melatonin production increases at night, promoting sleepiness, while exposure to light in the morning halts melatonin, encouraging wakefulness.
- Aligning circadian rhythms with natural light improves sleep quality.
Types of Sleep
- Sleep architecture refers to the organization of normal sleep encompassing NREM and REM stages.
Diagnosing Sleep Disorders
- Insomnia: Trouble falling/staying asleep due to various factors, including discomfort, anxiety, and environmental changes.
- Risks include injury from sleepwalking, ineffective coping with insufficient sleep, and fatigue from sleep deprivation.
- Common issues include sleep apnea, anxiety from diagnoses, and unmet knowledge about nonprescription sleep remedies.
Planning
- Aim to maintain sleep patterns that provide adequate energy and improve feelings of well-being.
- Nursing interventions include minimizing distractions, promoting bedtime rituals, comfort measures, and teaching good sleep hygiene.
Implementing
Creating a Restful Environment
- Minimize noise and ensure comfortable room temperature and ventilation.
- In healthcare settings: place beds low, use night lights, and make call bells accessible.
Promoting Comfort and Relaxation
- Consider loose-fitting nightwear and hygienic routines for clients.
- Close curtains to block external lights and reduce overhead lighting.
- Minimize noise by maintaining low conversations and adhering to policies regarding communal media usage.
- Encourage voiding before bed and provide back massages for relaxation.
- Ensure a clear pathway to avoid disturbances at night.
- Use supportive devices for dependent clients to ensure comfort.
Additional Considerations
- Schedule medication administration effectively and consider prewarming bed linens.
- Utilize comfortable 100% cotton flannel sheets.
