Rnur 141 Sensory Deprivation

  1. Sensory Deprivation leads to:
    • Boredom
    • Confusion
    • Irritability
    • Disorientation
    • Anxiety
  2. Sensory Deprivation Prevention includes:
    • Color
    • Pictures
    • Textures
    • Smells
    • Sounds
    • Interpret Environment
    • Change scene often
  3. Definition:
    CATARACTS
    • clouding of normally clear, transparent lens.
    • Chemical changes in lens protein
    • Leading cause of blindiness in the world
  4. Causes of Cataracts
    • Aging
    • Congenital
    • Trauma
    • Long term corticosteroid use
    • Diabetes
    • Radiation Exposure (Sun)
  5. Clinical manifestations of Cataracts
    • Decreased visual acuity
    • Glare sensitivity
    • Poor night vision
    • Pupil may appear gray or pearly white
  6. Diagnostics of Catarcts
    • Snellen visual acuity test
    • Opthalmoscopy
    • Slit-lamp biomicroscopic exam
  7. Treatment of Cataracts
    • No nonsurgical treatment cures cataracts.
    • Use glasses, contact lens, bifocals, magnifying lens.
    • Surgical-extracapsular, removes ant capsule and lens, place plastic lens
  8. Complications of Cataracts
    • Corneal damage
    • Glaucoma
    • Hemorrhage
    • IOL malposition
    • Secondary lens develops
  9. Cataracts Post Op Care
    • May read and watch TV
    • NO bending forward, rubbing, straining, lifting over 15 lbs, driving, coughing, sneezing, vomiting
    • Kneel or squat
    • Sleep with protective shield
    • Sleep on back
    • Wear glasses during day
    • Sunglasses outside
    • MEDS: Steroids, Antibiotics
    • REPORT: pain, headache, ocular redness, swelling, drainage, discharge ,changes in visual acuity
  10. Definition:
    GLAUCOMA
    • "Silent thief of sight"
    • Visual field loss from damage to optic nerve from high intraocular pressure generally
    • Asymptomatic until extensive & irreversible damage done
    • Leading cause of blindness in the US
    • High risks: Diabetics, Afr Amer, family hx, eye trauma
  11. Classifications of Glaucoma
    • Open Angle
    • Angle Closure
    • Primary
    • Secondary
  12. Diagnosis of Glaucoma
    • Assess ocular history, medications
    • Opthalmic exam
    • Tonometry to measure IOP (air puff test)
  13. Clinical manifestations of Glaucoma
    • Blurred vision
    • Halo vision
    • Difficulty focusing, adjusting eyes in low lighting
    • Loss of peripheral vision
    • Aching or discomfort around eyes
    • Headache
  14. Treatment of Glaucoma
    • Goal: prevent optic nerve damage and maintain IOP w/in range
    • B Blockers: Timolol, Betagen, Betoptic
    • Cholinergics: Pilocarpine
    • Surgery: Iridectomy, Laser Trabeculoplasty
  15. Glaucoma Post Op Care
    • No driving, straining, lifting or bending for 1 week
    • Patch 24 hrs a day
    • No water in eye
    • Antiobiotic drops
    • Corticosteroid drops
  16. Consequences of
    HEARING LOSS
    • Speech discrimination lost
    • Social isolation
    • Lower performance on mental exams
    • Depression
    • Boredom
    • Safety issues
    • Can't test reality-leads to paranoia
  17. Conductive Hearing Loss
    • decreased or absent transmission of sound from external auditory canal to and through the middle ear.
    • Caused by: impacted cerumen, loss of elasticity of tympanic membrane, bone ridigidity-otosclerosis
  18. Sensorineural Hearing Loss
    gradual hearing loss in elder, involves damage to cochlea or vestibulocochlear nerve
  19. Presbycusis
    • progressive hearing loss
    • Caused by: noise damage, aging, ototoxicity (drug toxicity)
  20. Risk Factors for Hearing Loss
    • family history
    • congenital malformations of the cranial structure
    • low birth weight
    • use of ototoxic meds
    • recurrent ear infxns
    • bacterial meningitis
    • chronic exposure to loud noises
    • perforation of tympanic membrane
