Part 1 of 3
Question 1: Which of the following best describes the primary goal of Orientation
and Mobility (O&M) instruction for individuals who are blind or visually impaired?
A. To teach the individual to memorize all routes in their community
B. To enable the individual to travel independently, safely, and efficiently in various
environments
C. To ensure the individual relies on sighted guides for all unfamiliar travel
D. To focus exclusively on long cane techniques for outdoor travel
CORRECT ANSWER: B. To enable the individual to travel independently, safely, and
efficiently in various environments
RATIONALE: The fundamental purpose of O&M instruction is to foster independent
travel skills that promote safety, efficiency, and confidence across diverse settings.
While route memorization, sighted guide techniques, and cane skills are components of
instruction, they serve the broader goal of functional independence rather than being
ends in themselves.
Question 2: According to the ACVREP Code of Ethics, an O&M specialist must
prioritize which of the following when developing an instructional plan?
A. The preferences of the funding agency
B. The individual's personal goals, needs, and informed choices
C. Standardized protocols that apply to all clients regardless of context
D. The specialist's area of greatest expertise
CORRECT ANSWER: B. The individual's personal goals, needs, and informed
choices
RATIONALE: Ethical practice in O&M requires client-centered planning that respects
autonomy and self-determination. The ACVREP Code of Ethics emphasizes that
services must be tailored to the individual's unique circumstances, goals, and informed
preferences, rather than external pressures or practitioner convenience.
Question 3: Which anatomical structure is primarily responsible for converting
light into neural signals in the visual pathway?
A. Optic nerve
B. Lens
C. Retina
D. Cornea
CORRECT ANSWER: C. Retina
,RATIONALE: The retina contains photoreceptor cells (rods and cones) that transduce
light energy into electrochemical signals. These signals are then processed by retinal
neurons and transmitted via the optic nerve to the brain. The lens and cornea focus
light, while the optic nerve conducts signals but does not perform phototransduction.
Question 4: A client with retinitis pigmentosa typically experiences which pattern
of visual field loss?
A. Central scotoma with preserved peripheral vision
B. Homonymous hemianopsia
C. Progressive peripheral vision loss leading to tunnel vision
D. Sudden, complete vision loss in one eye
CORRECT ANSWER: C. Progressive peripheral vision loss leading to tunnel vision
RATIONALE: Retinitis pigmentosa is a degenerative condition that initially affects rod
photoreceptors in the peripheral retina, resulting in night blindness and progressive
constriction of the visual field. Central vision is often preserved until later stages,
creating a "tunnel vision" effect that significantly impacts mobility and environmental
awareness.
Question 5: During an O&M assessment, which method is most appropriate for
evaluating a client's ability to detect drop-offs?
A. Asking the client to describe what a drop-off looks like
B. Observing the client's cane technique while approaching a known curb
C. Administering a written test on drop-off safety
D. Having the client walk with eyes closed in a controlled environment
CORRECT ANSWER: B. Observing the client's cane technique while approaching a
known curb
RATIONALE: Functional assessment of drop-off detection requires direct observation of
the client's applied skills in a real or simulated environment. The long cane is designed
to detect surface changes ahead of the traveler; observing technique at a curb provides
valid, performance-based data about the client's ability to identify and respond to drop-
offs safely.
Question 6: Which concept development skill is foundational for a young child
learning orientation and mobility?
A. Reading braille maps
B. Understanding cardinal directions
C. Developing body image and laterality
D. Using a GPS device
CORRECT ANSWER: C. Developing body image and laterality
RATIONALE: Body image (awareness of one's body parts and their positions) and
laterality (understanding left/right distinctions on one's own body) are prerequisite
,spatial concepts for O&M. These foundational skills must be established before more
complex orientation tasks, such as map reading or cardinal direction use, can be
effectively taught.
Question 7: When teaching the constant contact cane technique, the specialist
should instruct the client to maintain contact between the cane tip and the ground:
A. Only when crossing streets
B. Continuously throughout the arc of the cane swing
C. Only when detecting obstacles
D. Intermittently to conserve energy
CORRECT ANSWER: B. Continuously throughout the arc of the cane swing
RATIONALE: The constant contact technique requires the cane tip to maintain
continuous ground contact during the lateral arc. This provides consistent tactile and
auditory feedback about surface texture, alignment, and drop-offs, enhancing
environmental awareness and safety compared to techniques where contact is
intermittent.
Question 8: Which of the following is the most appropriate initial response when a
client using a sighted guide technique encounters a narrow passage?
A. The guide should walk ahead and call directions
B. The guide should switch to leading with one hand behind their back
C. The guide should bring both arms behind their back and the client should follow
directly behind
D. The client should release the guide and use their cane independently
CORRECT ANSWER: C. The guide should bring both arms behind their back and the
client should follow directly behind
RATIONALE: In narrow passages, the standard sighted guide protocol directs the guide
to place both arms behind their back, signaling the client to move directly behind them
in single file. This maintains physical contact and clear communication while adapting
to spatial constraints, ensuring safety without abandoning the established technique.
Question 9: An O&M specialist is planning instruction for a client with low vision
who benefits from high-contrast visual cues. Which environmental modification
would best support this client's travel?
A. Installing fluorescent lighting throughout the home
B. Using black tape to mark the edges of white stairs
C. Removing all rugs to eliminate tripping hazards
D. Painting all walls the same neutral color
CORRECT ANSWER: B. Using black tape to mark the edges of white stairs
RATIONALE: High-contrast visual cues enhance edge detection for individuals with low
vision. Applying black tape to the leading edge of light-colored stairs creates a strong
, luminance contrast that improves depth perception and step identification, directly
supporting safe mobility. Other options do not specifically address contrast
enhancement.
Question 10: Which legal mandate requires public schools to provide O&M services
to eligible students with visual impairments?
A. Americans with Disabilities Act (ADA)
B. Rehabilitation Act of 1973, Section 504
C. Individuals with Disabilities Education Act (IDEA)
D. Fair Housing Act
CORRECT ANSWER: C. Individuals with Disabilities Education Act (IDEA)
RATIONALE: IDEA specifically includes "orientation and mobility services" as a related
service for children with visual impairments who require them to benefit from special
education. While the ADA and Section 504 provide broader civil rights protections, IDEA
is the statutory authority mandating O&M services within the educational context.
Question 11: When assessing a client's auditory skills for O&M, which task best
evaluates sound localization ability?
A. Identifying the pitch of a tone
B. Determining the direction of a stationary sound source
C. Recognizing familiar environmental sounds
D. Measuring hearing threshold levels
CORRECT ANSWER: B. Determining the direction of a stationary sound source
RATIONALE: Sound localization—the ability to identify the direction and distance of a
sound—is critical for orientation and hazard detection. Assessing this skill requires the
client to indicate the direction of a controlled, stationary sound source, which directly
measures spatial auditory processing relevant to travel safety.
Question 12: Which factor is most critical when determining the appropriate cane
length for a client?
A. The client's age
B. The client's height and posture during travel
C. The color of the cane
D. The client's preferred grip style
CORRECT ANSWER: B. The client's height and posture during travel
RATIONALE: Proper cane length is determined by the client's height and typical posture
while walking, ensuring the tip contacts the ground approximately one step ahead and
allows for effective arc technique. An improperly sized cane compromises drop-off
detection, obstacle identification, and overall travel efficiency.
