Key Takeaways

  • Sleep cycles include NREM stages 1-3 and REM sleep, each serving different restorative functions
  • Sleep hygiene practices include consistent schedule, optimal environment, and limiting stimulants
  • Cluster nursing care at night to minimize sleep interruptions
  • Use non-pharmacological comfort measures before or alongside medications
  • PQRST is a systematic method for comprehensive pain assessment

Rest, Sleep, and Comfort Measures

Rest and sleep are essential for healing, immune function, and overall well-being. LPN/VNs must understand sleep physiology, recognize sleep disturbances, and implement interventions that promote restorative rest while managing pain through various comfort measures.

Sleep Physiology

Sleep occurs in cycles of approximately 90 minutes, alternating between two main types:

Sleep StageCharacteristicsImportance
NREM Stage 1Light sleep, easily awakenedTransition to sleep
NREM Stage 2Deeper sleep, eye movement stopsPhysical restoration begins
NREM Stage 3Deep sleep, slow delta wavesPhysical restoration, growth hormone release
REM SleepRapid eye movement, dreaming, muscle atoniaMemory consolidation, cognitive restoration

Normal Sleep Duration by Age:

  • Infants: 14-17 hours
  • Toddlers: 11-14 hours
  • School-age: 9-11 hours
  • Adults: 7-9 hours
  • Older adults: 7-8 hours (often fragmented)

Common Sleep Disorders

DisorderDescriptionKey Interventions
InsomniaDifficulty falling/staying asleepSleep hygiene, relaxation, medications if needed
Sleep ApneaBreathing pauses during sleepCPAP/BiPAP, weight loss, positional therapy
NarcolepsyExcessive daytime sleepiness, sudden sleep attacksScheduled naps, stimulant medications
Restless Leg SyndromeUncomfortable leg sensations, urge to moveMovement, iron supplementation, medications
Circadian Rhythm DisordersSleep-wake cycle disruptionLight therapy, melatonin, schedule adjustment

Sleep Hygiene Education

Teach patients these evidence-based sleep hygiene practices:

  1. Maintain consistent sleep schedule - Same bedtime/wake time daily, including weekends
  2. Create optimal sleep environment - Dark, quiet, cool (65-68°F)
  3. Limit screen time - No electronic devices 1 hour before bed
  4. Avoid stimulants - No caffeine 6+ hours before bed, limit alcohol
  5. Exercise regularly - But not within 3-4 hours of bedtime
  6. Limit naps - If needed, keep to 20-30 minutes before 3 PM
  7. Reserve bed for sleep - Avoid working, watching TV in bed
  8. Wind-down routine - Relaxing activities before bed (reading, bath)

Hospitalized Patient Sleep Considerations

Hospital environments often disrupt sleep. Nursing interventions include:

  • Cluster care activities to minimize nighttime interruptions
  • Dim lights during night hours
  • Reduce noise levels (silence alarms promptly, lower voices)
  • Provide earplugs and eye masks if desired
  • Maintain patient's normal sleep routines when possible
  • Assess and treat pain before bedtime
  • Limit fluids before sleep to reduce nocturia

Non-Pharmacological Pain Management

LPN/VNs implement various comfort measures that complement medication therapy:

InterventionMechanismNursing Actions
Heat ApplicationVasodilation, muscle relaxationWarm packs, heating pads (check temperature, protect skin)
Cold ApplicationVasoconstriction, reduced inflammationIce packs (20 min max, protect skin)
PositioningReduces pressure, supports alignmentPillows, bed positioning, specialty surfaces
MassageRelaxation, circulation, gate controlBack rub, hand/foot massage (check contraindications)
DistractionRefocuses attentionMusic, TV, conversation, reading
RelaxationReduces muscle tension, anxietyDeep breathing, guided imagery, progressive relaxation
TENS UnitElectrical stimulation blocks pain signalsApply electrodes as ordered, check skin

Pain Assessment

Accurate pain assessment guides intervention:

Pain Assessment Scales:

  • Numeric Rating Scale (NRS): 0-10 (0 = no pain, 10 = worst pain)
  • Wong-Baker FACES: Visual faces for children, cognitive impairment
  • FLACC Scale: Face, Legs, Activity, Cry, Consolability (for nonverbal patients)

PQRST Pain Assessment:

  • P = Provocation/Palliation (What makes it better/worse?)
  • Q = Quality (Sharp, dull, burning, aching?)
  • R = Region/Radiation (Where is it? Does it spread?)
  • S = Severity (0-10 scale)
  • T = Timing (When did it start? Constant or intermittent?)

Rest and Activity Balance

Promote therapeutic rest while preventing complications of immobility:

  • Plan activities to allow rest periods
  • Prioritize essential tasks when energy is limited
  • Teach energy conservation techniques for chronic illness
  • Balance activity with rest during recovery
  • Assess for signs of fatigue (vital sign changes, pallor, weakness)
