cognitive and sensory power point Flashcards
cognition is
knowing influenced by awareness and jedgement
sensation is
a feeling withing or outside the body
perception is
the way the brain perceives information
reticular activating system is
the area of the brain that controls alertness and attention
sensory adaptation is
the brains process of filtering impulses by priority during times of alertness
tactile receptors include
general senses of touch
pressure
tempreature
pain
special senses are
smell
taste
hearing
equilibrium
vision
aging affect/ and what it causes
decreased neurons
gradual decline in the ability to interpret sensory stimuli
response time is slower
cognitive alteration include
delirium
demetia
depression
delirium signs and symptoms
fluctuating awareness
impairment of memory
disorganized thinking
hallucinations
disturbance of sleep-wake cycles
dementia causes what
decline in cognitive abilities
Alzheimer disease
depression signs and symptoms
loss of intrest
sadness for exteded period of time
decreased self esteem
inomnia or too much sleep
changes in eating pattrens
brain injuries and illnesses include
cerebrovascular accident (CVA)
meningitis
cerebrovascular accident (CVA) could cause
aphasia
tactile deficit cause
peripheral neuropathy
smell deficit cause
insomnia
taste deficit cause
decreased gustatory cells
hearing deficit cause
conductive hearing loss
sensorineural hearing loss
prebycusis
equilibrium deficit cause
motion sickness
Meniere’s disease
vision deficit cause
myopia
presbyopia
cataracts
glaucoma
diabetic retinopathy
macular degeneration
sensory deprevation is
person who cant hear see feel respond to the environment
my feel socially isolated
sensory overload is
overabundance of stimuli
when the brain is overly stimulated it ceases to make sense of incoming stimuli
sensory overload symptoms
anxiety
attention deficit
confusion
smoking, obesity, high cholesterol diet, high alcohol use causes
hypertension and increase risk of stroke
cocaine use causes
decreased sense of smell
stress causes
hypertension
metabolic syndrome causes
high risk for developing sensory deficits
lack of sleep causes
impaired concentration
bad judgement and mental abilities
blurred vision
decreased response to auditory stimuli
enviromental toxins causes
damage to special sense organs
loud noises causes
hearing loss
excessive uv light causes
cataract development, visual impairment
some medications alter
sensory and cognitive status
sensory assessment physical part include
vital signs
neurologic assessment
CBC
electrolytes
blood glucose levels
urinalysis and culture sensitivity testing
effects of age, illness, stress, trauna on cognition and sensation
ability to communicate
special senses
ability to perform ADLs
chronic confusion signs
alert and oriented to person only
unable to express his needs
repeats questions asked
responds with unrelated comments
wanders frequently
impaired verbal communications signs and symptoms
alterations of central nevous sytem
CVA
inability to recognize words or understand question
risk for social isolation
alterations in mental status
demetia
sad affect
saying they feel so alone
when caring for patient with cognitive alterations you should
Orient to person, place, and time
Maintain a safe environment
Keep communication clear and simple
Provider reminders for or assistance with self-care
when caring for patient with tactile alterations
Test the temperature of bath water
Monitor extremities frequently
Turn and reposition patients who are unable to move in bed independently at least every 2 hours
Keep sharp objects away from the affected area.
when caring for patients with olfactory and gustatory alterations
Encourage intake of a well-balanced diet
Serve highly aromatic foods
Remain diligent about oral hygiene
Encourage patients to eat a variety of foods and enhance flavor with spices and herb
when caring for patients with auditory alterations
Encourage patients with hearing aids to use them in the hospital
Keep hearing aid in working order and prevent loss
Face the patient when speaking
Speaking clearly and slowly without shouting
Minimize background noise
Use written instructions, if practical
Use a sign language interpreter, as needed
Use in-room technology to assist with communication
when caring for patients with equilibrium alterations
Instruct patient to call for assistance when ambulating
Keep a basin on the bedside stand for patients experiencing nausea or vomiting
Keep the lights dim and minimize noise
Keep the floor clear of obstacles
when caring for patients with visual alterations
Orient patient to placement of items in the hospital room.
Keep call light and assistive devices within reach
when caring for patients with sensory deprivation
Provide social interaction and tactile stimulation
when caring for patients with sensory overload
Reduce sensory stimuli
