Question 3

Which modification BEST addresses the needs of a client with severe arthritis who has difficulty operating standard door hardware?

Accepted Answer

Lever-style door handle

Answer

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?

Accepted Answer

1:48 (2.08%)

Answer

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?

Accepted Answer

Client cannot transfer independently at the top landing

Answer

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.
