Chapter 39 (Sensory Alterations) Vocab Flashcards
Accommodation
the process of accommodating or adapting
in older adults, this process is decreased due to vision changes
Age-Related Macular Degeneration
an eye disease that causes the progressive loss of central vision
Auditory
the sense of hearing
Cataracts
a clouding of the lens of the eye that obstructs the passage of light
Diabetic Retinopathy
an eye disease caused by damage to the blood vessels in the eye and resulting in vision loss
Glaucoma
condition of increased pressure within the eyeball, that causes damage to the retina and optic nerve, causing gradual loss of sight
Gustatory
the sense of taste
Meniere’s Disease
a progressive disease of the inner ear that can cause dizziness, ringing of the ears, hearing loss, and/or the feeling of pressure or congestion in the ear
Olfactory
the sense of smell
Ototoxic (ototoxicity)
the state of being poisonous to the ear
Usually refers to a drug that is damaging to the ear/hearing (drugs like analgesics, antibiotics, or diuretics)
Presbycusis
age related hearing loss
Presbyopia
the gradual loss of your eyes’ ability to focus on nearby objects (farsightedness) caused by loss of elasticity of the lens of the eye
Proprioception
perception or awareness of the position and movement of the body
Sensory Deficits
deficit in the normal function of sensory reception and perception
ex: hearing and vision loss
Sensory Deprivation
inadequate quality or quantity of stimulation
Ex: covid restrictions, bed rest, etc
Sensory Overload
reception of multiple sensory stimuli
Tactile
the sense of touch
Tinnitus
Ringing in the ears
Types of Sensory Alterations
- sensory deficits
- sensory deprivation
- sensory overload
Sensory Status
part of the assessment
finding out what they can see, smell, touch, etc
onset and duration of symptoms and aggravating/alleviating factors
Normal Sensation Sensory Experiences
Reception - stimulation of a receptor such as light, touch, or sound
Perception - integration and interpretation of stimuli
Reaction - the reaction to stimuli that is important to the person
Sensory Reception
The stimulation of nerve fibers that comes from the five senses, pressure, pain, temperature, vibration, and position
Once a stimulation is sensed, then what..
transmission of impulses to higher centers of the brain occurs
