Navigation Skills
Question 1: Which of the following is the PRIMARY purpose of the constant contact
cane technique?
A. To maximize auditory cues from the environment
B. To maintain continuous tactile feedback about the travel surface
C. To reduce physical fatigue during extended travel
D. To improve the aesthetic appearance of cane use
CORRECT ANSWER: B. To maintain continuous tactile feedback about the travel
surface
RATIONALE: The constant contact technique involves keeping the cane tip in
continuous contact with the ground, providing the traveler with ongoing tactile
information about surface texture, drop-offs, and obstacles. This continuous feedback
enhances environmental awareness and safety, particularly for detecting subtle
changes in terrain that might be missed with intermittent contact techniques.
Question 2: When teaching a student with congenital blindness to use a human
guide, which instruction should be introduced FIRST?
A. How to navigate through narrow spaces
B. How to locate and grasp the guide's elbow
C. How to position themselves one-half step behind the guide
D. How to communicate directional cues to the guide
CORRECT ANSWER: B. How to locate and grasp the guide's elbow
RATIONALE: The foundational skill in human guide technique is establishing proper
physical contact. Teaching the student to independently locate and grasp the guide's
elbow above the elbow joint creates the essential connection needed before
introducing positioning, movement patterns, or communication strategies. This
sequential approach ensures safety and builds confidence.
Question 3: Which sensory system is MOST critical for a traveler to detect a drop-
off at the edge of a curb?
A. Auditory
B. Visual
C. Tactile-kinesthetic
D. Olfactory
CORRECT ANSWER: C. Tactile-kinesthetic

Navigation Skills
RATIONALE: The tactile-kinesthetic system provides information through foot contact
and body movement. When approaching a curb, the traveler's foot detects the absence
of surface support (drop-off) through proprioceptive and tactile feedback before
stepping down. While auditory and residual visual cues may supplement this detection,
tactile-kinesthetic input is primary for immediate drop-off detection during cane or foot
travel.
Question 4: An O&M specialist is assessing a client's ability to square off to a
building facade. Which skill is being evaluated?
A. Trail following
B. Alignment
C. Shorelining
D. Echo location
CORRECT ANSWER: B. Alignment
RATIONALE: Squaring off refers to positioning one's body perpendicular or parallel to a
surface, which is a fundamental alignment skill. Proper alignment is essential for
maintaining direction, executing turns accurately, and establishing a reference frame for
navigation. This assessment determines the client's ability to orient their body relative
to environmental features.
Question 5: Which of the following BEST describes the purpose of a pre-cane
program?
A. To determine if a client is ready for a long cane
B. To develop foundational sensory, motor, and concept skills before introducing a long
cane
C. To replace the need for a long cane in young children
D. To assess visual acuity for cane selection
CORRECT ANSWER: B. To develop foundational sensory, motor, and concept skills
before introducing a long cane
RATIONALE: Pre-cane programs focus on building essential skills such as body image,
spatial concepts, sensory development, and protective techniques that form the
foundation for successful long cane use. These programs prepare individuals
cognitively, physically, and emotionally for the complex task of independent travel with
a long cane, rather than serving as a readiness test or cane substitute.

Question 6: When instructing a client in the two-point touch cane technique, the
arc width should approximately equal:
A. The client's shoulder width
B. The client's height
C. Twice the client's shoulder width
D. The length of the client's arm
CORRECT ANSWER: A. The client's shoulder width
RATIONALE: In the two-point touch technique, the cane arc should match the traveler's
shoulder width to ensure detection of obstacles within the path of travel while
maintaining efficient, rhythmic movement. An arc too narrow may miss obstacles; an
arc too wide causes unnecessary movement and fatigue. Shoulder-width arc provides
optimal coverage aligned with the body's travel path.
Question 7: Which environmental cue is MOST reliable for a traveler using echo
location to identify an open doorway?
A. Change in air temperature
B. Change in sound reflection pattern
C. Change in surface texture underfoot
D. Change in ambient light level
CORRECT ANSWER: B. Change in sound reflection pattern
RATIONALE: Echo location relies on detecting changes in how sound waves reflect off
surfaces. An open doorway creates a distinct acoustic shadow or change in
reverberation compared to a solid wall, allowing trained travelers to perceive the
opening through auditory feedback. While other cues may supplement detection, the
acoustic change is the primary echo location indicator.
Question 8: A client consistently veers to the right when traveling on a straight path.
Which intervention should the O&M specialist implement FIRST?
A. Introduce a compass app on a smartphone
B. Assess and correct body alignment and posture
C. Recommend a guide dog evaluation
D. Increase the length of practice routes
CORRECT ANSWER: B. Assess and correct body alignment and posture

Navigation Skills
RATIONALE: Veering often results from subtle misalignments in posture, head position,
or shoulder orientation. Before introducing technological aids or extending route
complexity, the specialist must evaluate and address fundamental biomechanical
factors. Correcting alignment addresses the root cause and establishes a foundation
for accurate straight-line travel.
Question 9: Which of the following is a PRIMARY safety consideration when
teaching cane techniques on escalators?
A. Using the constant contact technique throughout
B. Identifying the emergency stop button location
C. Maintaining contact with the handrail while positioning the cane
D. Removing the cane before stepping onto the escalator
CORRECT ANSWER: C. Maintaining contact with the handrail while positioning the
cane
RATIONALE: Safety on escalators requires maintaining balance through handrail
contact while using the cane to detect the comb plate and step edges. The cane should
be positioned to avoid entanglement while still providing tactile feedback. Removing the
cane eliminates critical drop-off detection; constant contact may be impractical on
moving steps.
Question 10: When teaching a student to use landmarks for navigation, which
characteristic makes a landmark MOST effective?
A. It is visually distinctive to sighted peers
B. It is permanent, detectable through the student's available senses, and uniquely
positioned
C. It is mentioned frequently in verbal directions
D. It is located at every intersection along the route
CORRECT ANSWER: B. It is permanent, detectable through the student's available
senses, and uniquely positioned
RATIONALE: Effective landmarks must be reliable (permanent), perceivable through the
traveler's sensory channels (tactile, auditory, olfactory, or residual vision), and
distinctive enough to avoid confusion with other features. These characteristics ensure
the landmark serves as a consistent, unambiguous reference point for orientation and
decision-making during independent travel.
