COMS ACVREP QUESTIONS AND
CORRECT ANSWERS
Touch and Drag Cane Techniques ANSW✅✅Using the cane to follow a guideline or shoreline of a
different texture to locate an intersecting surface (e.g., sidewalk) or to regain a parallel line of travel
by maintaining the tip's contact with the ground during the arc toward the ground being followed.
Touch and Slide ANSW✅✅Using the cane to locate drop-offs (e.g. curbs, stairs) or texture changes
by keeping the can tip on the ground and letting it slide slightly forward when making the arc of the
touch technique to provide more feedback.
What is an advantage of a dog guide? ANSW✅✅Leading a person in a straight line from point A to
point B.
Stopping for all changes in elevation, including curbs and stairs.
Stopping for overhead obstacles, such as tree limbs.
Avoiding obstacles in their path.
What does damage at the optic chiasm disrupt? ANSW✅✅Damage at the optic chiasm disrupts
the nasal retinal fibers of both eyes resulting in a loss of both temporal visual fields.
What is a useful three-step process for helping a dog guide handler learn a new route?
ANSW✅✅orientation
coaching
solo
Why do young children with visual impairments show lags in environment exploration?
ANSW✅✅awareness of existing objects is limited
What should be determined before beginning to train a learner to use eccentric viewing?
ANSW✅✅The best viewing angle
If a learner demonstrates a change in gait over time, she may be experiencing peripheral
neuropathy. What should you ask? ANSW✅✅Check for sores on your feet
, It is described as a result of damage to the nerves located outside of the brain and spinal cord
(peripheral nerves), often causes weakness, numbness and pain, usually in the hands and feet. It can
also affect other areas and body functions including digestion, urination and circulation.
Which is a characteristic of gait patterns commonly seen in young learners who are born without
functional vision? ANSW✅✅Larger Degree of Out-toeing
Which technique does a learner use to become familiarized with environments if the learner uses
object-to-object spatial relationships? ANSW✅✅Cognitive Mapping - a mental map of where
objects are in a space
What is a feature of traffic signals which impacts crossing? ANSW✅✅actuation - Vehicle-actuated
control uses information on current demands and operations, obtained from detectors within the
intersection, to alter one or more aspects of the signal timing on a cycle-by-cycle basis
Split Phase traffic signal ANSW✅✅Split phasing is a signal design that gives a green phase for all
vehicle movements of one direction (e.g., northbound through, right, and left) followed by a phase
for all movements of the opposite direction (e.g., southbound through, right, and left).
Two Phase traffic signal ANSW✅✅Two phase system is usually adopted if through traffic is
significant compared to the turning movements.
What should a learner listen to in order to facilitate skill in using echolocation? ANSW✅✅His
footsteps as they approach a wall
What should a learner who is experiencing hypoglycemia be given? ANSW✅✅a glucose tablet
(low glucose)
What is a major advantage of using a primary ETA? ANSW✅✅Extended preview of route
Hearing loss in the lower frequencies would impact what... ANSW✅✅distinguishing men's voices
from females and children, certain vowel sounds that are lower than constants, lower base sounds in
music
What is a bilateral hearing loss? ANSW✅✅Hearing loss in both ears, which could be symmetrical
(the same degree of loss in both ears) or asymmetrical (different levels of loss in each ear)
