common pathway for all sensory perception
- special sensory receptor stimulated
- impulse travels to brain [RAS, emotion]
- opposite cortex interprets: by quality, memory
- reactions: emotional, motor, etc.
too much or too many types of stimulation
common in when admitted into the hospital or in critical care areas [new settings]
not getting enough of a normal stimuli that you should be getting for someone in your situation
can occur whenever you take away the normal stimuli that help orient a person i.e. calendar, clock, etc.
one of the senses is not working as well as usual [any of the sense may be affected]
overload can cause?
can cause anxiety, restless, reacing thoughts, mood swings, irritable and intolerance of stimuli [esp. pain], fingering of tubes
deprivation can cause
causes boredom, confusion, disorientation, looks like psych illness
deficit can cause
depend on sensory organ affected, pt. can end up with decreased self-seteem, denial [to cope with sensory loss], safety issues [esp. in people with denial], communication problems common
goals for overload
decrease abnormal stimuli in the environment, protect them
goals for deprivation
increase pleasant stimuli in environment, ENRICH by providing calendars, clocks, opening the shades.
goals for people with sensory deficit
- provide a safe environment
- maximal self-care
- maintain self esteem
- maximize communication
- involve support people
common types of HEARING loss in the YOUNG
- otitis media [inner ear infection]
common types of HEARING loss in the OLD
- cerumen [wax build up]
common types of HEARING loss in pts. with trauma or disease
- ototoxic meds
- noise [exposure]
common types of VSION loss in the YOUNG
- congenital infection
- premature with oxygen, high sats
common types of VSION loss in OLDER pts.
- cataracts, macular degeneration
common types of VSION loss in trauma or disease pts.
- diabetic retinopathy
what type of information do we want to know about hearing loss
- How bad is it?
- When do they experience this loss? Adult or child
- What type of loss are they having?
- What type of frequency and how severe is it?
timing and acuity, severity and frequencies
what are the two basic types of hearing loss
- - conductive loss
- - sensory neural loss
cognitive or sensory-neural problems
- - congenital blockages
- - otitis
- - cerumen
- - neural
- inflammation of the ear. Common problem
- for kids. They cry a lot or can affect language development. Its treatable
irrigate the ear canal which can restore the persons hearing. Common in older adults
Neural hearing loss
- congenital,noise damage, ototoxic meds [causes rining in the ears, disorientation of the person, hearing loss], aging [can involve a
- lot of denial thus preventing pt. from getting Tx]
nursing interventions for hearing loss
- Assistive devices, animals
- ¡Promoting self esteem – seen esp
- in older adults who see it as a sign of some deterioration and may get upset if
- your implying they cant hear well enough
