Occupational Therapist Test Assistive Technology 4 — Questions and Answers
Question 1: Which wheelchair cushion type provides the BEST pressure redistribution for a client at high risk for pressure injuries?
- Foam cushion
- Air flotation cushion (Correct answer)
- Gel cushion
- Solid seat insert
Correct answer: Air flotation cushion
Air flotation cushions provide superior immersion and envelopment properties, allowing optimal pressure redistribution for high-risk individuals.
Question 2: An OT is assessing a client's home for environmental control unit (ECU) installation. Which client factor is the PRIMARY prerequisite?
- Insurance coverage for the device
- The client's cognitive ability to learn and use the system (Correct answer)
- Number of smart devices in the home
- Caregiver's willingness to assist
Correct answer: The client's cognitive ability to learn and use the system
Cognitive ability to understand and operate an ECU is the primary prerequisite, as the technology is only effective if the user can learn to use it reliably.
Question 3: Which AT device category falls under the 'low-tech' classification?
- Voice output communication aid
- Dynavox SGD
- Built-up handle utensils (Correct answer)
- Powered exoskeleton
Correct answer: Built-up handle utensils
Built-up handle utensils are low-tech AT because they require no power source or electronics, relying solely on modified design to improve grip.
Question 4: When prescribing a rollator walker for a client with Parkinson's disease, which feature is MOST important to include?
- Seat and backrest for resting
- Laser line projection to cue stepping (Correct answer)
- Basket for carrying items
- Adjustable handle height
Correct answer: Laser line projection to cue stepping
Laser line projection provides an external visual cue that helps overcome freezing of gait in Parkinson's disease by cueing step initiation.
Question 5: A school-based OT is recommending AT for a student with dysgraphia. Which tool MOST directly addresses the writing impairment?
- Text-to-speech software
- Speech-to-text software (Correct answer)
- Colored overlays for reading
- FM system
Correct answer: Speech-to-text software
Speech-to-text software allows the student to produce written work by speaking, bypassing the motor planning and execution deficits associated with dysgraphia.
Question 6: Which dimension of the International Classification of Functioning, Disability and Health (ICF) does AT MOST directly target?
- Body structure impairment
- Activity and participation (Correct answer)
- Environmental factors only
- Personal factors
Correct answer: Activity and participation
AT primarily targets the activity and participation dimension of the ICF by enabling performance of daily tasks and community involvement despite impairment.
Question 7: A client with upper extremity amputation is being fitted for a myoelectric prosthesis. What is the OT's PRIMARY role during initial training?
- Adjusting the socket fit
- Teaching electrode site activation and functional use patterns (Correct answer)
- Programming the device's control software
- Ordering the prosthetic components
Correct answer: Teaching electrode site activation and functional use patterns
The OT trains the client to voluntarily activate the residual limb muscles at electrode sites and practice functional use patterns for ADL performance.
