OT Master of Occupational Therapy MCQ 5

Question 1

Which splint design is MOST appropriate for a client with a radial nerve injury resulting in wrist drop?

Accepted Answer

Wrist cock-up splint (wrist extension splint)

Answer

A wrist cock-up splint positions the wrist in extension to compensate for the lost wrist extensor function caused by radial nerve injury.

Question 2

During a dynamic systems theory approach to motor development, which factor is considered the RATE LIMITER for a skill such as walking?

Accepted Answer

The weakest or least developed component system needed for the task

Answer

Dynamic systems theory identifies the rate limiter as the subsystem that is least developed, which constrains emergence of the new motor skill.

Question 3

An OT working in hand therapy documents a grip strength of 15 kg on the right and 30 kg on the left in a right-handed client. The right grip strength represents approximately what percentage of the norm?

Accepted Answer

50%

Answer

The right grip (15 kg) is 50% of the left grip (30 kg), indicating significant deficit; the expected dominant-to-nondominant ratio is approximately 10% greater.

Question 4

A client with Parkinson's disease is having difficulty walking through doorways due to freezing of gait. Which OT cueing strategy is MOST effective?

Accepted Answer

Rhythmic auditory cueing (metronome or music)

Answer

Rhythmic auditory cues provide an external timing signal that bypasses the disrupted basal ganglia circuitry and helps initiate and maintain gait in Parkinson's disease.

Question 5

Which evidence level is considered HIGHEST in the evidence-based practice hierarchy?

Accepted Answer

Systematic review of RCTs

Answer

Systematic reviews and meta-analyses of multiple RCTs represent the highest level of evidence because they synthesize rigorous controlled data across multiple studies.
