306 exam 2 Flashcards
Eye Disorders
Cataracts-
A clouding of the lens of the eye that causes vision to be blurry, hazy, or less colorful.
Glaucoma-
An increase in intraocular pressure due to the buildup of fluid, or aqueous humor, that causes compression of the optic nerve.
Open Angle: Tunnel Vision, Gradual loss of vision
Closed Angle: Severe pain, sudden onset of decreased vision
Eye Exams: Increased Ocular pressure
Treatment: Eye drops, Laser eye surgery
Acute Macular Degeneration-
An irreversible degeneration of the macula that leads to a loss of central vision as clients age.
Diabetic Retinopathy-
affects blood vessels in the retina causing blindness.
Astigmatism-
A defect that causes both nearby and faraway objects to appear blurry

Eye Safety
Wear goggles or safety glasses in an environment that is dangerous
Hyperopia
Inability to see nearby objects clearly, also referred to as farsightedness.
Myopia
Inability to see faraway objects clearly, also referred to as nearsightedness.
Astigmatism
A defect in the eye making objects nearby and faraway look blurry or distorted
Presbyopia
Age-related farsightedness, or a gradual decrease in the ability to clearly see nearby caused by the loss of flexibility of the lens of the eye.
Sensorineural Hearing Deficit
Effects inner ear, nerve pathway
Could be associated with tinnitus and vertigo
Age related presbycusis, followed by noise-induced hearing loss
Congenital, genetic or acquired
Noise-induced hearing loss
Associated with prolonged exposure to sounds greeted than 85 dB including loud music
Can be caused by single exposure to intense sound over 120dB
Wear ear protection, avoid loud situations
Warning signs are inability to hear from 3 feet away
Conductive Hearing loss
Loss of hearing at all frequencies
Most common cause: Obstruction of external ear canal
Impacted cerumen
Perforated tympanic membrane
Otosclerosis
Abnormal growth of bone in the middle ear.
Otitis Media
Inflammation in or the accumulation of fluid in the middle ear that can result in conductive hearing loss
Occupational Risks for hearing loss
Machinery, Planes, other loud environments
Presbycusis
Age-related hearing loss.
Hair cells of cochlea ______ With aging
degenerate
______ pitched tones, conversational speech lost initiaially
High
Sensorineural hearing loss
Hearing loss that occurs from problems either in the inner ear or on the vestibulocochlear (auditory) nerve (cranial nerve VIII).
Conductive Hearing loss
Inability of sound to travel from the outer ear to the eardrum and middle ear.
Blockage in ear canal
Tinnitus
Hearing sound when no external sound is present, such as ringing, buzzing, roaring, clicking, hissing, or humming noises.
Vertigo
a sensation of motion or spinning that is often described as dizziness
TORCH
Toxoplasmosis, Rubella, Cytomegalovirus, Syphilis, Herpes
Idiopathic neuropathy
Neuropathy due to nerve damage of an unknown cause.
Peripheral Neuropathy
Conditions that occur when nerves in the central nervous system become damaged resulting in numbness, pain, and weakness to the extremities.
Diabetic neuropathy
Nerve damage that occurs in clients who have diabetes mellitus due to high blood glucose levels and high levels of triglycerides, which cause damage to the nerves and to the small blood vessels supplying blood to the nerves.
Rinne test
Tuning fork on mastoid bone, when client cannot hear it place it outside auditory canal
Weber Test
Place the tuning fork on the middle of forehead, detect if the client hears the sound equally. Can detect sensorineural issues
Sensory processing disorder
When a client appropriately detects sensory stimuli, but their brain has difficulty interpreting and responding appropriately to the stimuli.
Sensory Deficit
A deficit in the expected function of one or more of the five senses.
Sensory Deprivation
A reduction in or absence of stimuli to one or more of the five senses.
Sensory Overload
Receiving stimuli at a rate and intensity beyond the brain’s ability to process the stimuli in a meaningful way.
Ototoxicity
Causing damage to or dysfunction of the cochlea or vestibule.
Aphasia
A disorder that affects a client s ability to articulate and understand speech and written language due to damage in the brain (National Institute on Deafness and Other Communication Disorders).
Tactile Hypersensitivity
Being overly sensitive to tactile stimulilation.
Tactile Defensiveness
A severe sensitivity to touch that most people would find acceptable that often causes physical pain.
Tactile Hyposentivity
Under-responsiveness to tactile stimulation.
Gustatory Cells
Taste cells that contain specific receptors that allow for differentiation between sweet, sour, bitter, salty, or savory flavors.
Hypogeusia
A decreased ability to taste.
Dysgusia
A persistent salty, rancid, or metallic taste is said to have dysgeusia.
Aguesia
The inability to taste anything.
Phantom taste perception
A persistent, foul taste when the mouth is empty.
Hyposmia
A reduction in the ability to perceive odors.
Anosmia
The inability to smell anything.
Phantosmia
The sensation of an odor that isn’t there.
Parosmia
a distortion in smells, such as when a previously pleasant smell becomes unpleasant.
