UIUC RST 230 Final Exam UPDATED
ACTUAL QUESTIONS AND CORRECT
ANSWERS
Terms visually impaired, partially sighted, or low vision describe... - CORRECT ANSWER a
serious loss in vision that cannot be corrected by medical or surgical procedures or with conventional
glasses
The quality of vision is measured by which two factors? - CORRECT ANSWER 1. acuity
2. visual field
Define acuity - CORRECT ANSWER the amount of detail an individual sees compared to
what a person with normal vision sees
Define visual field. What is a normal degree for one to see? - CORRECT ANSWER -this
includes the entire area that can be seen at one time with the fixed eye
-170 degrees is normal
Tunnel vision VS peripheral vision (TEST!) - CORRECT ANSWER tunnel vision is when you
can only see straight ahead and not to the side. Peripheral vision is when you can see to the side, but
not straight ahead
Define ocular dominance & the miles test - CORRECT ANSWER -the tendency to prefer
visual input from one eye over the other
-create a triangle with hands
Visual impairments- cataracts (what is it) - CORRECT ANSWER It's when your lens become
milky or cloudy and the cloudiness distorts rays of light and prevents light from being focused on the
retina. It is the primary cause of blindness among older adults
Visual impairments- cataracts (symtoms) - CORRECT ANSWER blurred vision, double vision,
poor night vision, need for bright lights while reading
,Visual impairments- cataracts (causes) - CORRECT ANSWER -lack of oxygen, which leads to
disturbance in the nutrition of the lends
-external forces (i.e. electrical shock, wounds, or x-rays)
Visual impairments- glaucoma - CORRECT ANSWER it is caused by the increased pressure,
due to liquid, within the eyeball (optic nerve). This results in damage to the optic nerve. Symptoms
are loss of peripheral vision, sensitivity to light and glare, problems with night vision, and blurred
vision
Visual impairments- diabetic retinopathy - CORRECT ANSWER Diabetes causes changes in
blood vessels in the retina that causes hemorrhaging. One of the most common causes of visual
impairments and blindness in the US. Symptoms are spots floating in the visual field, vision loss,
blurred vision, and poor night vision
List the causes of visual impairments - CORRECT ANSWER -Aging (#1)
-Congenital (born with it)
-Brain injury
-Disease
-Accidents
-Sports injuries
-Stupidity
Tools for those who are living with visual impairments - CORRECT ANSWER -White canes
-GPS devices
-Guide dogs
-Echolocation
Define hearing impairment - CORRECT ANSWER General term used to describe all types of
hearing loss, ranging from very mild to profound deafness
Define deafness - CORRECT ANSWER When a person is unable to understand speech
through the ear alone, either with or without hearing aids
, Define hard of hearing - CORRECT ANSWER People who have mild to moderate hearing loss
pre-lingual vs post-lingual hearing loss - CORRECT ANSWER Pre: A hearing loss that occurs
before speech develops (born deaf or very young)
Post: Occurs after an adult person learns to speak
How does congenital hearing loss occur? - CORRECT ANSWER 1. maternal viral infection
2. Rh incompatibility
How are rhesus babies made? - CORRECT ANSWER When a woman is negative and the man
is positive
What happens to the mother and baby when Rh is incompatible? - CORRECT ANSWER -The
babies blood will enter the bloodstream of the mothers and the mom will treat the babies protein as a
disease. She'll start to create antibodies to try to kill the red blood cells of the baby. The child will be
born fine. -However, since the mother already create antibodies, she will start to kill her next baby.
Shots and bloodwork can prevent this, though.
Describe conductive hearing loss - CORRECT ANSWER -Outer or middle ear
-Obstruction of the ear canal, puncture of ear drum, or otosclerosis (calcification and softening of the
three little bones in the middle ear)
Describe sensorineural hearing loss - CORRECT ANSWER -Cochlea
-Aging, viral infections, noise levels, Rh incompatibility, fevers
Describe central hearing loss - CORRECT ANSWER -Hearing portions of the brain
-pathways to the brain or the brain itself is damaged due to an accident, tumor, etc
What are the methods of communicating to those who are hard of hearing? How should you properly
communicate? - CORRECT ANSWER -Lip reading
-Sign language
-technical assistance (i.e. hearing aids)
