What is a conscious process of selecting, organizing, and interpreting sensory stimuli that requires intect and functioning sense organs, nercous pathways, and the brain?
sensory perception
What do these three things provide?
- sensory receptors
- reticular activiting system (RAS)
- functioning nervous pathways
sensory awareness
What is the process of sensory perception?
- stimuli is received by the sense and transmitted to the RAS.
- multiple stimuli are converted by the RAS into an impluse and conducted to the cerbral cortx
- cerebral cortex perceives the impluse.
What are the speical senses of normal sensory perception?
- sight
- hearing
- smell
- taste
- touch
- kinesthetic sensation
- visceral sensation
that state of optimum arousal is called?
sensoristasis
what is it called when sensory receptors adapt to repeated stimulation by responding less and less?
adaptation
What are the factors affecting sensory perception?
- environment
- previous experience
- lifestyle and habits
- illness
- medications
- age
- variations of stimulation
Results of altered sensory function are?
- anxiety
- cognitive dysfunction
- hallucinations/delusions
- sensory deficits
- depression/withdrawal
What is it called when a person is unable to process or manage the intensity and quanity of incoming sensory stimuli?
sensory overload
What is a lessening or lack of meaningful sensory stimuli, monotonous sensory input, or an interference with the processing of information called?
sensory deprivation
What is an impaired function in sensory reception or perception?
sensory deficit
What are some factors affecting sensory perception?
- age
- culture
- language
- activity level
- medical history
- medications
- experience with healthcare settings
Sensory overload or sensory deprivation can lead to?
hyperactive or hypoactive delirium - should resolve in three weeks.
What are some clinical signs of sensory overload?
- anxiety
- irritability
- and inability to concentrate
Sensory overload can lead to?
hyperactive delirium
Sensory deprivation can lead to?
hypoactive delirium
Implementation of health promotion is?
- patient teaching
- procedure preparation
- nurse-patient interaction
What are some nursing interventions for altered sensory preception?
- stimulation provision
- stimulation reduction
- sensory aids
- safety
Sensory safety precautions are?
altered sense of touch
altered sense of smell
hearing deficits
visual deficits
