CEAC Environmental Modification & Accessibility Design 3 — Questions and Answers
Question 1: A client uses a power wheelchair with a turning radius of 30 inches. What minimum clear floor space is needed for a 180-degree turn?
- 48 × 48 inches
- 60-inch diameter circle (Correct answer)
- 56 × 64 inches T-turn space
- 72-inch diameter circle
Correct answer: 60-inch diameter circle
ADA Standards require a 60-inch diameter clear floor space to allow a wheelchair 180-degree turn.
Question 2: In accessible bathroom design, the centerline of a toilet must be located how far from the side wall in a standard ADA-compliant configuration?
- 15 inches
- 16–18 inches
- 17–19 inches (Correct answer)
- 18–21 inches
Correct answer: 17–19 inches
ADA Standards require the toilet centerline to be between 17 and 19 inches from the side wall or partition.
Question 3: Which modification BEST addresses the needs of a client with severe arthritis who has difficulty operating standard door hardware?
- Deadbolt lock with larger key
- Round knob with rubber grip cover
- Lever-style door handle (Correct answer)
- Push-plate on pull side only
Correct answer: Lever-style door handle
Lever-style door handles require minimal grip strength and can be operated with a closed fist or forearm, making them ideal for arthritis.
Question 4: What is the maximum cross-slope permitted on an accessible pedestrian route according to ADA Standards?
- 1:12
- 1:33 (3%)
- 1:48 (2.08%) (Correct answer)
- 1:20 (5%)
Correct answer: 1:48 (2.08%)
ADA Standards limit cross-slope on accessible routes to 1:48 (approximately 2%) to prevent wheelchair drift.
Question 5: A stairway chairlift is being considered for a client. Which condition would make this modification LEAST appropriate?
- Client has limited upper extremity strength
- Stairway has a curved or angled configuration
- Client lives alone with no caregiver
- Client cannot transfer independently at the top landing (Correct answer)
Correct answer: Client cannot transfer independently at the top landing
If a client cannot independently transfer from the chairlift to a wheelchair or walking surface at the landing, the chairlift creates a safety hazard rather than solving the mobility problem.
Question 6: In a roll-in shower designed per ADA Standards, what is the minimum clear floor space required?
- 36 × 36 inches
- 36 × 60 inches (Correct answer)
- 60 × 30 inches
- 36 × 48 inches
Correct answer: 36 × 60 inches
ADA Standards require a minimum 36 × 60-inch clear floor space for a transfer-type roll-in shower.
Question 7: When evaluating a client's home for aging in place, the FIRST step in the CEAC assessment process is:
- Recommend modifications based on diagnosis
- Conduct a functional mobility assessment (Correct answer)
- Review the client's medical records
- Measure all doorways and hallways
Correct answer: Conduct a functional mobility assessment
A functional mobility assessment establishes the client's actual performance in their environment, which drives all subsequent modification recommendations.
