Natcep day 7

  1. 1. Recognizing Changes in Body Function NATCEP Day Seven
  2. 2. Objectives • Describe changes in vision that may accompany aging • Describe how the NA might recognize that a resident has impaired vision • Name diseases that may cause visual impairment • Describe ways to change the environment to encourage the visually impaired resident’s independence and to promote safety • Describe ways to care for the visually impaired resident • Describe changes in hearing that may accompany aging
  3. 3. Visual changes that may occur with aging • Reduced ability to focus vision. • Decreased sharpness of vision. • Loss of peripheral vision. • Reduced ability to acclimate to darkness. • Increased sensitivity to glare. • Possible impairment of color vision from cataracts.
  4. 4. Diseases that may cause Visual Loss • Cataracts – Clouding of the lens of the eyes • Glaucoma – Damage to the optic nerve – Caused by ncreased internal pressure in eye • Blood vessel damage – Diabetes – High Blood Pressure • Cerebral Vascular Accident (CVA) – Commonly known as Stroke – May remove part of visual field
  5. 5. Diseases that may cause Visual Loss • Macular Degeneration – Leading cause of severe vision loss in people over age 60 – Occurs when small central portion of the retina (macula) deteriorates. – Retina is the light-sensing nerve tissue at the back of the eye.
  6. 6. Environmental accommodations • Place objects where the resident can see them; keep the same location. • Keep surroundings uncluttered. • Provide good lighting & adjust blinds to prevent glare. • Use large print on signs, black on white.
  7. 7. Eye Glass care • Wearing correct eye glasses. • Clean and fit properly. • Store properly when not in use.
  8. 8. Hearing Changes • Reduced ability to hear high-pitched sounds. • Reduced acuity.
  9. 9. Clues to hearing loss • Speaks louder than necessary or increases volume of TV/radio. • Asks for words to be repeated. • Does not react to a sound out of the visual field.
  10. 10. Communication • Speak clearly, slowly, facing the resident. • Turn off background noise.
  11. 11. Hearing Aid/Cochlear Implant care • Replace batteries as needed. • Clean according to manufacturer’s instructions. • Store according to manufacturer’s instructions – EXPENSIVE!
