Question 1

A client with C7 complete SCI has an advantage over C6 in which key seating-related functional area?

Accepted Answer

Ability to perform push-up pressure relief due to intact triceps (elbow extensors)

Answer

The C7 myotome includes triceps; intact elbow extension enables the push-up pressure relief maneuver that is not typically possible at C6 due to absent triceps function.

Question 2

Orthostatic hypotension is MOST commonly a seating and positioning concern for clients with which condition?

Accepted Answer

High-level spinal cord injury (T6 and above)

Answer

High-level SCI disrupts the sympathetic nervous system's ability to regulate blood pressure, making orthostatic hypotension a significant risk when transitioning to upright positioning.

Question 3

A seating specialist evaluating a client with Friedreich's ataxia should prioritize which intervention for the PRIMARY trunk control challenge?

Accepted Answer

Lateral trunk supports to manage trunk ataxia and improve midline stability

Answer

Friedreich's ataxia produces progressive cerebellar ataxia with trunk instability in multiple planes; lateral trunk supports address the characteristic oscillatory trunk movement.

Question 4

Which medical condition creates the HIGHEST combined risk for seating-related pressure injury due to simultaneous sensory impairment AND vascular compromise?

Accepted Answer

Diabetes mellitus with peripheral neuropathy

Answer

Peripheral neuropathy in diabetes eliminates protective sensation while diabetic vasculopathy impairs tissue perfusion, creating a dual-mechanism risk for pressure injury that exceeds other conditions listed.

Question 5

A client with post-polio syndrome who currently uses a manual wheelchair reports increasing upper extremity pain and weakness with propulsion. What does this finding indicate?

Accepted Answer

A need for reassessment and likely transition to power mobility to protect remaining function

Answer

Post-polio syndrome causes progressive overuse weakness; increasing UE pain and fatigue with propulsion signals that the manual wheelchair is compromising remaining motor units and power mobility should be evaluated.
