Hearing and Vision Flashcards
Age related changes to the ear
Degenerative changes in inner ear
* Narrowing of auditory meatus from
bone apposition (Squeeze closer together)
* Diminished blood supply
* Central nervous system changes
Diff bw hard of hearing and deaf?
HOH is a level of hearing impairment
Deafness is Profound hearing loss
Three categories of Hearing impairment
Prelingual (HOH occurs very young)
Postlingual (Occurs sometimes after age 2)
Presbycusis (age related degeneration of auditory structure)
Risk Factors affecting hearing wellness
male gender, increased age
genetic predisposition
exposure to noise
impacted cerumen
smoking
exposure to secondhand smoke
ototoxic medications
certain medical conditions
Most prevalent risk factos for impaired hearing
Noise induced hearing loss
- Preventable
- Prolonged
- Associated with occupations and rec activities
Types of hearing impairment
Conductive (abnormalities of external and middle ear) - sound ability to pass through canal
Sensorineural hearing loss: Abnormalities of sensor and neural structures of inner ear
Mixed: Involving both
Adjunct
Exacerbates
Hearing Assessment
Otoscopic exam
Tuning fork tests for hearing
Screening tools
Family history with past and present risks
Attitudes abt hearing aids
Nursing diagnoses
Readiness for enhanced communication
* Anxiety
* Impaired social interaction
* Ineffective coping
* Risk for loneliness
* Risk for injury
Eye Related change
arcus senilis, loss of
orbital fat and diminished elasticity of eyelid muscles—
usually do not interfere with vision
Diminished tear production
Degenerative changes affect the retinal-neural pathway and visual cortex of the brain
Less efficient at taking in light and interpreting
Visual impairment
Loss CANNOT be corrected, ranging from mild to blindness
Mild impairment
Caused by normal age related changes, excarebated by environmental conditions such as glare and poor lighting
Presbyopia
Loss of accomodation
Risk factors affecting visual wellness
Lifestyle
Nutrition
Smoking + exposure
Sunlight exposure
Chronic conditions + medications
Functional Consequences Affecting visual wellness
Presbyopia ***
Need for 3-5 times more light than previously
Difficulty with night dribng
Increased risk for mobility and falls
Increased difficulty in performing usual activities
Anxiety, depression and lower levels of psychological
well-being
Effect on driving
