sensory alterations - CORRECT ANSWERS ✔✔alterations to a
|\ |\ |\ |\ |\ |\ |\ |\


persons normal senses that effect their ability to function and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


relate effectively |\




-sensory deficits: deficit in the normal function of sensory
|\ |\ |\ |\ |\ |\ |\ |\ |\


reception and perception |\ |\




-sensory deprivation: reduced sensory input, the elimination of
|\ |\ |\ |\ |\ |\ |\ |\


patterns or meaning from input, and restrictive environments
|\ |\ |\ |\ |\ |\ |\ |\


that produce monotony and boredom
|\ |\ |\ |\




-sensory overload: when a person receives multiple sensory
|\ |\ |\ |\ |\ |\ |\ |\


stimuli and cannot perceptually disregard or selectively ignore
|\ |\ |\ |\ |\ |\ |\ |\


some stimuli |\




visual deficits - CORRECT ANSWERS ✔✔-cataract: cloudiness of
|\ |\ |\ |\ |\ |\ |\ |\


the lens interfering with passage of light causing problems with
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


glare and blurred vision
|\ |\ |\




-glaucoma: intraocular pressure against the optic nerve which |\ |\ |\ |\ |\ |\ |\ |\


distorted vision, leads to blindness, and halo effect around lights
|\ |\ |\ |\ |\ |\ |\ |\ |\




-diabetic retinopathy: veins in the eyes become occluded
|\ |\ |\ |\ |\ |\ |\ |\


decreasing oxygen/blood supply resulting in blindness |\ |\ |\ |\ |\




-muscle degeneration: progressive damage to the retina resulting
|\ |\ |\ |\ |\ |\ |\


in central blindness
|\ |\ |\




-presbyopia: gradual decline in the ability of the lens to |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


accommodate or focus on close objects resulting in inability to |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


see near objects clearly
|\ |\ |\

,hearing deficits - CORRECT ANSWERS ✔✔-cerumen accumulation:
|\ |\ |\ |\ |\ |\


buildup of cerumen which becomes hard and obstructs the ear
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


canal resulting in hard of hearing/ conduction deafness
|\ |\ |\ |\ |\ |\ |\




-presbycusis: common progressive hearing disorder in older |\ |\ |\ |\ |\ |\ |\


adults


taste deficits - CORRECT ANSWERS ✔✔-xerostomia: decrease in
|\ |\ |\ |\ |\ |\ |\ |\


salivary production that leads to thicker mucus and a dry mouth
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


leading to appetite and nutritional problems
|\ |\ |\ |\ |\




balance deficits - CORRECT ANSWERS ✔✔-dizziness and
|\ |\ |\ |\ |\ |\ |\


disequilibrium: common condition in older adulthood usually |\ |\ |\ |\ |\ |\ |\


resulting from vestibular dysfunction resulting in episodes of
|\ |\ |\ |\ |\ |\ |\ |\


vertigo or disequilibrium |\ |\




neurological deficits - CORRECT ANSWERS ✔✔-peripheral |\ |\ |\ |\ |\ |\


neuropathy: disorder of the peripheral nervous system, |\ |\ |\ |\ |\ |\ |\


characterized by symptoms that include numbness and tingling |\ |\ |\ |\ |\ |\ |\ |\


of the affected area and stumbling gait
|\ |\ |\ |\ |\ |\




-stroke: cerebrovascular accident caused by clot, hemorrhage, or
|\ |\ |\ |\ |\ |\ |\ |\


emboli disrupting blood flow to the brain. creates altered
|\ |\ |\ |\ |\ |\ |\ |\ |\


proprioception with marked incoordination and imbalance. loss of |\ |\ |\ |\ |\ |\ |\


sensation and motor function occurs. left brain stroke effects
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


right side resulting in difficulty with speech. right brain stroke
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


effects the left side resulting in visual spatial alterations
|\ |\ |\ |\ |\ |\ |\ |\




sensory deprivation - CORRECT ANSWERS ✔✔a state in which
|\ |\ |\ |\ |\ |\ |\ |\ |\


there is little or no normal sensory stimulation resulting in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


monotony and boredom |\ |\




-symptoms: confusion, severe electrolyte imbalance |\ |\ |\ |\

, sensory overload - CORRECT ANSWERS ✔✔reception of multiple
|\ |\ |\ |\ |\ |\ |\ |\


sensory stimuli |\




-a person no longer perceives the environment in a way that
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


makes sense |\




-prevents meaningful response by the brain
|\ |\ |\ |\ |\




-symptoms: racing thoughts, scattered attention, restlessness,
|\ |\ |\ |\ |\ |\


and anxiety
|\




factors influencing sensory function - CORRECT ANSWERS ✔✔-
|\ |\ |\ |\ |\ |\ |\


age: infants and children are at risk for visual and hearing
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


impairment, hearing changes begin at the age of 30, gustatory
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


and olfactory changes begin around age 50, proprioceptive
|\ |\ |\ |\ |\ |\ |\ |\


changes common after age 60 |\ |\ |\ |\




-meaningful stimuli: reduce the incidence of sensory deprivation
|\ |\ |\ |\ |\ |\ |\




-amount of stimuli: excessive stimuli cause sensory overload
|\ |\ |\ |\ |\ |\ |\




-social interaction: amount and quality of social contact with
|\ |\ |\ |\ |\ |\ |\ |\ |\


supportive family members and significant others influence
|\ |\ |\ |\ |\ |\ |\


sensory function |\




-environmental factors: persons occupation places him at risk for |\ |\ |\ |\ |\ |\ |\ |\ |\


hearing, visual, and peripheral nerve alterations
|\ |\ |\ |\ |\




-cultural factors: some sensory alterations occur more commonly
|\ |\ |\ |\ |\ |\ |\ |\


in select cultural groups
|\ |\ |\




proprioceptive - CORRECT ANSWERS ✔✔position of the body |\ |\ |\ |\ |\ |\ |\




communication deficits - CORRECT ANSWERS ✔✔trouble |\ |\ |\ |\ |\ |\


speaking, understanding, naming, reading, or writing
|\ |\ |\ |\ |\
