OTR OTR Adaptive Equipment & Assistive Technology 1 — Questions and Answers
Question 1: Which type of wheelchair cushion is most appropriate for a client with Stage II pressure injuries and limited repositioning ability?
- Foam cushion
- Air-flotation cushion (Correct answer)
- Gel cushion
- Solid insert cushion
Correct answer: Air-flotation cushion
Air-flotation cushions provide dynamic pressure redistribution and are indicated for clients with existing pressure injuries who cannot reposition frequently.
Question 2: A client with C6 tetraplegia wants to feed themselves independently. Which adaptive device is MOST appropriate?
- Universal cuff with utensil slot (Correct answer)
- Rocker knife
- Built-up handle spoon
- Plate guard only
Correct answer: Universal cuff with utensil slot
A universal cuff with a utensil slot compensates for absent hand grasp in C6 tetraplegia by securing utensils to the palm using wrist extension.
Question 3: When recommending a reacher for a client post-total hip arthroplasty (posterior approach), the primary purpose is to:
- Improve grip strength
- Maintain hip precautions by avoiding hip flexion beyond 90° (Correct answer)
- Increase shoulder range of motion
- Reduce lower extremity edema
Correct answer: Maintain hip precautions by avoiding hip flexion beyond 90°
A reacher allows the client to retrieve objects from the floor or low surfaces while maintaining posterior hip precautions that restrict hip flexion beyond 90°.
Question 4: Which augmentative and alternative communication (AAC) device feature is MOST critical for a client with ALS who retains only eye movement?
- Touch screen with large icons
- Voice output with recorded messages
- Eye-gaze technology (Correct answer)
- Single switch scanning
Correct answer: Eye-gaze technology
Eye-gaze technology allows individuals who retain only volitional eye movement, as in late-stage ALS, to select messages by directing their gaze.
Question 5: A client with rheumatoid arthritis reports difficulty turning door knobs. Which assistive device follows joint protection principles?
- Foam tubing over knob
- Lever-style door handle (Correct answer)
- D-ring door pull
- Hook-and-loop strap handle
Correct answer: Lever-style door handle
Lever-style door handles require a pushing or pulling motion that avoids lateral pinch and ulnar deviation, consistent with joint protection for rheumatoid arthritis.
Question 6: Which factor is MOST important when performing a wheelchair seating evaluation to determine seat depth?
- Client's weight
- Distance from back of buttocks to popliteal fossa minus 1–2 inches (Correct answer)
- Seat-to-floor height
- Armrest height
Correct answer: Distance from back of buttocks to popliteal fossa minus 1–2 inches
Seat depth is measured from the back of the buttocks to the popliteal fossa and then reduced by 1–2 inches to prevent pressure behind the knees.
