You are completing a seating and mobility evaluation for an individual who requires a new wheelchair. In sitting, you measure the width of the hips as 16” and the distance from the PSIS to the back of the knee as 18”. Based on these measurements , which of the following would you recommend as the ideal dimension of the wheelchair seating surface to provide a comfortable, secure fit and allow for functional mobility?
22” wide x 24” deep
16” wide x 18” deep
18” wide x 16” deep
15” wide x 17” deep
18” wide x 16” deep
Which of the following anatomical landmarks creates the highest-pressure areas when sitting and should be monitored for skin breakdown and prevention of pressure sores?
pubis and iliac crest
sacrum and ischial tuberosities
femoral head and lesser trochanter
iliac crest and lesser trochanter
sacrum and ischial tuberosities
The functional purpose of the patella includes all of the following except:
- increasing the moment arm (leverage) of the quadriceps for knee extension.
- providing anterior stability to the knee during flexion.
- remaining static with motion of the knee
- providing a protective coverage
remaining static with motion of the knee
To decrease the force demands of the quadriceps and improve safety with bathroom transfers, which of the following would be the most beneficial modification?
- provide a raised toilet seat
- install a tub shower
- install hardwood or linoleum flooring
- providing a protective covering
provide a raised toilet seat

C. lateral roatation of the femur relative to the tibia
D. medial rotation of the tibia relative to the femur
B. lateral rotation of the tibia relative to the femur
Genu varum, or excessive inward (medial) angulation of the tibia relative to the femur, would most likely contribute to osteoarthritis on which aspect of the tibial plateau?
A. posterior
B. Lateral
C. Medial
D. Anterior
C. Medial
What is the essential functional purpose of the intrinsic muscles of the foot?
A. Provide individual motion of the toes
B. Generate force for dorsiflexion and plantar flexion of the foot and ankle.
C. Generate force for eversion and inversion of the ankle and foot.
D. Stabalize the arches of the foot during weight bearing
D. Stabalize the arches of the foot during weight bearing
