A client reports difficulty operating a round doorknob due to reduced hand strength. What is the most appropriate hardware replacement?

Turning radius describes the floor space required for a wheelchair to complete a turn; a 60-inch diameter circle accommodates a full 360° turn.
Which type of stairlift track configuration is required when a staircase makes a 90-degree turn between floors?

What is the recommended mounting height range for light switches and electrical outlets in an accessible home to serve both standing and seated users?
Answer: Switches at 42–48 inches, outlets at 18–48 inches
Placing switches between 42–48 inches and outlets between 18–48 inches creates an overlapping zone reachable from both standing and seated positions.
A client with low vision needs contrast improvements in their home. Which modification provides the most functional benefit at stair edges?

High-contrast nosing strips define the edge of each tread clearly, which is the most critical visual cue for safe stair navigation with low vision.
When assessing a bathroom door for wheelchair access, which door type offers the greatest usable floor space inside the bathroom?
