Study Notes

Sensory Perception

  • Learning guides assist in exploring key concepts for course exams, ATI assessments, NCLEX, and nursing practice
  • Review sensory perception

Spinal Cord Injury (SCI)

  • The spinal cord is part of the central nervous system (CNS) and acts as a messenger system
  • SCI carries sensory information from the body to the brain
  • SCI sends motor signals from the brain to the body
  • SCI is responsible for autonomic regulation, including: breathing, circulation, digestion, urinary elimination, and sexual function

Classifications of SCI

  • Tetraplegia (quadriplegia) involves damage to the cervical region of the spinal cord
  • Paraplegia results from damage to the thoracic region of the spinal cord and extends through the lumbar/sacral vertebrae
  • Complete SCI is the interruption of all motor and sensory messaging below the level of injury
  • Incomplete SCI is when motor and sensory messages are not fully interrupted

Clinical Features of SCI

  • Loss of motor function
  • Loss of sensation
  • Loss of reflex activity
  • Loss of bowel and bladder control
  • Sexual dysfunction
  • Diagnostics include CT scans, MRI of the spine

Complications of SCI

  • Acute respiratory failure
  • Neurogenic shock (initial): cervical to thoracic cord, bradycardia, hypotension
  • Autonomic dysreflexia (later)
  • Stool incontinence, urinary incontinence, permanent paralysis
  • Pressure injury

Nursing Interventions for SCI

  • Maintain spinal alignment and immobilization by immobilizing the spine with a cervical collar and using a log-roll technique
  • Avoid twisting the client's torso
  • Monitor the airway, respirations, and breathing effort for respiratory support and prepare for intubation
  • Cardiac monitoring includes heart rate and blood pressure, and prepare to administer IV fluids for neurogenic shock
  • Maintain skin integrity by turning the client every 2 hours and manage incontinence
  • Provide appropriate nutritional support
  • Bowel and bladder management includes intermittent catheterization, teaching self-catheterization, scheduled voiding, checking for abdominal distension, and bowel training
  • Passive and/or active range of motion exercises
  • DVT prophylaxis involves sequential compression devices to lower extremities and anticoagulants
  • Monitor for depression

Autonomic Dysreflexia

  • Complication of tetraplegia caused by noxious stimuli below the level of injury
  • Examples include distended bladder, impacted rectum, and constrictive clothing
  • Injuries above T6 and in cervical lesions symptoms: severe hypertension, severe headache, nasal stuffiness, flushing, and bradycardia

Interventions for Autonomic Dysreflexia

  • Raise the head of the bed
  • Loosen tight clothing
  • Check for bladder distension or fecal impaction
  • Document the event

Ischemic Stroke

  • Medical emergency
  • Thrombus or embolus causes an abrupt alteration in cerebral perfusion, preventing oxygen from reaching the brain (ischemia)
  • Thrombus forms in the brain
  • Embolus is a clot to the brain
  • Cerebral edema causes further dysfunction

Risk Factors for Stroke

  • Thrombotic stroke (atherosclerosis): hypertension, diabetes mellitus, smoking
  • Embolic stroke: carotid artery disease (clot comes from blocked carotid arteries), atrial fibrillation (clot comes from left atrium), abnormal cardiac valves (endocarditis)
  • Transient Ischemic Attack (TIA) is considered "angina" of a "brain attack" as a warning sign of stroke
  • Localized ischemic event resolves
  • Neurological deficits last only minutes to hours and are never detected in imaging
  • Full functional recovery occurs within 24 hours

Clinical Features of Stroke

  • "BE FAST" (Balance, Eyes, Face, Arms, Speech, Time)
  • Balance: ataxia and vertigo
  • Eyes: blurry vision, diplopia, visual field deficits
  • Face: weakness, drooping, numbness
  • Arms and legs: extremity numbness or weakness
  • Speech and swallowing: aphasia, dysarthria, dysphagia
  • Time: onset of symptoms
  • Left hemisphere: analytical thought, language, reasoning, math, science, controls touch/movement on right side
  • Right hemisphere: spatial processing, emotion, art, music, visualization, controls touch/movement on left side

Diagnostics for Stroke

  • CT scan of the brain (no contrast to rule out hemorrhage)
  • Carotid artery duplex (ultrasound)
  • Electrocardiogram (ECG)
  • Echocardiogram

Nursing Interventions for Stroke

  • Determine the time of symptom onset
  • Administer thrombolytic therapy within 4.5 hours
  • Assess for contraindications: active bleeding, recent brain/spinal surgery, uncontrolled hypertension, low platelets or high PT/INR
  • Permissive hypertension is allowed for non-tPA clients up to 220/120mmHg

Monitoring in ICU

  • Bleeding precautions
  • Frequent neuro assessments & vital signs
  • Monitor signs of increased intracranial pressure

Acute Stage of Stroke

  • Monitor neurologic status
  • Perform bedside swallow assessment
  • Suction as needed
  • Elevate head of bed 15-30 degrees
  • Turn to unaffected side with head positioned midline
  • Passive and/or active range of motion exercises
  • Prevent complications: contractures, constipation/stool impaction, pressure ulcers, DVT
  • Aphasia: face the client, reduce background noise, don't shout, allow response time, ask yes/no questions
  • Hemineglect: client touches and uses both sides of the body
  • Hemianopsia: client moves head to scan, approach from unaffected side, place objects in visual field

Chronic Management of Stroke

  • Antiplatelet agents (aspirin)
  • Cholesterol-lowering medications (statins)
  • Strict blood pressure control (ACE inhibitors)
  • Smoking cessation

Pearson Concepts

  • Module 11: Intracranial Regulation (pp. 781-787)
  • Module 18: Sensory Perception (1419-1423)

Tests and Skills

Rosenbaum

  • Measures near vision by assessing the client's ability to read a chart 36 cm (14 inches) away
  • Screens for presbyopia by holding 35.5 cm (14 inches) away and correlates with the Snellen chart

Weber's

  • Technique: vibrating tuning fork on top of the client's head
  • Expected Finding: sound heard equally in both ears (negative Weber test).

Snellen

  • Measures distance vision having clients stand 6m (20ft) away
  • The numerator is 20 (distance in feet from the chart) with a larger denominator indicates poorer visual acuity
  • Screens for myopia (impaired far vision).

Romberg

  • Assesses balance by having the client stand with feet together, arms at sides, and eyes closed
  • Expected finding is minimal swaying for at least 5 seconds

Rinne

Technique: vibrates tuning fork firmly against the mastoid bone and then in front of the ear canal

  • Expected Air conduction (AC) sound longer than bone conduction (BC) sound; 2:1 ratio

Nursing Interventions for Clients Experiencing Sensory Deprivation

  • Provide meaningful stimulation, large-print materials, amplify phones, pleasant aromas.
  • Increase touch (if acceptable) with back rubs, hand holding, range-of-motion exercises, and hair care
  • Ensure client has vision and hearing assistive devices
  • Communicate frequently with the client
  • Encourage family flowers and pets
  • Provide objects with various textures
  • Encourage mental engagement (crossword puzzles, whistling, reciting)

Nursing Interventions for Clients Experiencing Sensory Overload

Environmental Stimuli and IICP

  • Overstimulation can exacerbate IICP, leading to further complications
  • Priority: Reduce environmental stimulation and avoid clustering multiple procedures
  • Create a Calm Environment by dimming lights, minimizing noise, and limiting conversations
  • Limit Visitors to reduce stimulation
  • Maintain a Calm Manner and approach the patient calmly
  • Elevate Head of Bed to 30 degrees to facilitate venous drainage and reduce ICP and avoid hyperextension or exaggerated neck flexion
  • Prevent Constipation and Bladder Distention by administering stool softeners and using methods like the Credé method
  • Educate family members on the importance of maintaining a quiet and calm environment

Brudzinski Sign

  • Symptoms: flex head towards the chest while lying supine, positive sign is involuntary flexion of the hips and knees
  • Findings: associated with meningitis, indicating irritation of the meninges

Kernig Sign

  • Symptoms: hip and knee are flexed at 90 degrees, and then the knee is straightened, a positive sign is pain/resistance in the lower back/hamstrings
  • Findings: positive sign suggests meningitis due to meningeal irritation

Patient Education for New Hearing Aid

  • Amplify sounds but do not help clients interpret what they hear
  • Amplification of sound be distracting and disturbing in a loud environment
  • Use the lowest setting that allows hearing without feedback
  • Clean the ear mold, use mild soap and water while keeping the hearing aid dry
  • When not in use, turn it off and remove the battery to conserve battery power
  • Keep replacement batteries on hand

Nursing Interventions for Clients with Vision Loss

  • Call clients by name before approaching to avoid startling them
  • Identify yourself and stay within clients' visual field if they have a partial loss
  • Give specific info about the location and explain interventions before touching
  • Before leaving, inform clients when leaving their presence
  • Appraise clients' clothing and politely suggest changes
  • Make audio players available
  • Describe the arrangement of the food on the tray before leaving the room

Loss of Hearing and Vision

Hearing Aids and Cochlear Implants

  • For severe hearing loss, these devices bypass damaged parts of the ear and directly stimulate the auditory nerve

Visual Aids:

  • Magnifiers, screen readers, and Braille materials help those with vision loss

Interventions:

  • Safety by ensuring a clutter-free environment with clear pathways and adequate lighting for visually impaired patients

Facilitate Communication:

  • By using clear speech, facing the patient, and employing visual aids or sign language for hearing-impaired individuals

Types of Hearing Loss

Sensorineural

  • Affects the inner ear, auditory nerve, or auditory pathways in the brain
  • High-frequency sounds are most affected, making speech discrimination difficult, especially in noisy environments
  • Common Conditions: Congenital issues, genetic factors, or acquired conditions like noise exposure or ototoxicity
  • Clinical: Tinnitus (ringing in the ears) is often associated, amplifier may be disruptive

Conductive

  • Disruption in sound transmission from the external ear to the inner ear
  • Finding: Equal loss of hearing at all sound frequencies
  • Speech discrimination remains good if the sound level is above the hearing threshold
  • Common: Obstruction (e.g., impacted cerumen), infections (e.g., otitis media), perforated tympanic membrane, or ossicle issues
  • often benefits from amplification by hearing aids as well as conditions like otitis media leading to temporary or permanent hearing loss if untreated.

Mixed

  • Combination of conductive and sensorineural elements affecting different parts of the auditory system
  • Requires a comprehensive approach to treatment, addressing both conductive and sensorineural components

Tools/Assessments/Methods for Eye/Vision Assessment

Snellen Chart

  • Used to assess distance vision.
  • The patient reads letters from a chart at 20 feet.
  • Normal vision is 20/20

Rosenbaum Chart

  • Used to assess near vision.
  • The patient reads from a card held 12-14 inches away.
  • Normal near vision is 14/14

Cardinal Fields of Vision

  • Finding: Assesses extraocular movements.
  • The patient follows a pen or finger through six fields of vision.

Ophthalmoscope

  • Used to visualize internal structures like the lens, vitreous humor, and retina.
  • Typically performed by a physician

Use of Negative Pressure Wound Therapy (NPWT)

  • Effective for chronic, acute, and traumatic wounds that are not healing well with traditional methods and dehisced wounds, used when surgical wounds reopen
  • Helps in managing partial-thickness burns that affect the top layers of skin, ulcers, pressure, and venous insufficiency ulcers, as well as flaps and grafts, assists in the preparation and healing of skin graft sites
  • Outcomes: Improved wound healing, decreased hospital stay, and enhanced oxygenation and blood flow

Cerebral Edema

  • Excessive fluid in the brain is caused by increased cerebrospinal fluid production, obstruction of drainage, or impaired reabsorption, masses/tumors, infection/encephalopathy, or vascular dysfunction
  • Finding: Increased intracranial pressure (ICP), headache, vomiting, change in level of consciousness, motor dysfunction (decorticate or decerebrate posturing), restlessness, hyperthermia, vision changes, abnormal pupil dilation, and Cushing triad
  • Maintain calm, non-stimulating environment
  • Keep the head of the bed elevated to 30 degrees and head in a neutral position
  • Monitor ICP, vitals, and neurological status
  • Prepare for endotracheal intubation
  • Administer as prescribed: Hypertonic saline, Osmotic diuretic, Stool softener, Antipyretics and Muscle relaxers

Cataract

  • Clouding or opacification of the lenses impairs visual acuity and is mainly age-related, can be unilateral or bilateral
  • Clinical: painless, progressive decline in vision, problem with night driving, difficulty reading, glare, and halos
  • Requires surgical intervention with artificial lens implantation, performed on one eye at a time
  • Postoperative: notify surgeon if vision acuity worsens, elevate head of bed, avoid activities that increase intraocular pressure Monitor for infection and wear eye patch
  • Expected finding: feeling of "sand" in the eye for 6-8 weeks, and photophobia requiring sunglasses in bright light.
