Sensory Flashcards
What are the senses involved in Sensory Reception?
- Visual
- Auditory
- Olfactory
- Gustatory
- Tactile
- Stereognosis
- Kinetic and visceral
What is Stereognosis?
Perception of solidity of objects.
What is the purpose of the kinesthetic and visceral senses?
They are the basic internal orienting systems.
What is Kinesthesia?
Awareness of positioning of body parts and body movement.
What does Visceral pertain to?
Inner organs.
What is Proprioception?
Subconscious movements and positions of the body [(independent of vision) touch the tip of nose].
Review table 44-3 for sensory deprivation and overload***
What are some nursing interventions to prevent sensory alterations?
- Control patient discomfort whenever possible
- Offer care that provides rest and comfort
- Be aware of need for sensory aids and prostheses
- Use social activities to stimulate senses and mind
- Enlist aid of family members to participate in or encourage activities
- Encourage physical activity and exercise
- Provide stimulation for as many senses as possible
What are some responses to sensory deprivation?
- Provide meaningful stimulation
- Amplify any sense in a respectful way you can (larger print for vision, pleasant aromas for smell, etc)
What are some responses to sensory overload?
- Minimize overall stimuli
- Vice versa of sensory deprivation (reduce unpleasant odors, etc)
What is Presbyopia?
Age-related loss of eye’s ability to focus on close objects.
What are Cataracts?
Opacity of lens, blocking entry of light rays into eye.
What is Glaucoma?
Increase in intraocular pressure, which can lead to blindness.
What is Diabetic Retinopathy?
Leakage and blockage of retinal blood vessels.
What is Macular Degeneration?
Deterioration of center of retina.
What does the Rinne test determine for conductive hearing loss?
Air conduction of sound less than or equal to bone conduction. (AC < or = BC).
What does the Rinne test determine for sensorineural hearing loss?
Expected response of air conduction being greater than bone conduction, but with length of time decreased for both (AC >BC).
What is the purpose of the RAS?
- Mediates arousal
- Allows all impulses to reach cerebral cortex and be perceived
What is sensoristasis?
The optimal arousal state of RAS.
What is the order for sensory perception to be successful?
- Presence of stimulus
- Conversion to a nerve impulse
- Conduction from receptor to brain
- Translation into a sensation.
