When measuring a patient for a manual wheelchair, seat width should be:
Answer: 1-2 inches wider than the widest point of the hips
Seat width should be 1-2 inches wider than the widest part of the hips or thighs, allowing comfortable seating without excessive lateral movement or pressure.
Which wheelchair component MOST directly prevents a patient from sliding forward out of the chair?
Answer: Lap/seat belt
A lap belt is the primary restraint for preventing forward sliding out of the wheelchair, directly securing the patient at the pelvis.
For a standing pivot transfer from wheelchair to mat table, the wheelchair should be positioned at what angle to the surface?
Answer: 45 degrees
A 45-degree angle minimizes the arc of rotation needed to complete the transfer, reducing physical demands on both the patient and clinician.
Pressure-relieving wheelchair cushions are MOST critical for patients with:
Answer: Sensory deficits and impaired self-repositioning ability
Patients with sensory deficits cannot detect pressure discomfort and impaired mobility prevents self-repositioning, placing them at the highest risk for pressure injuries.
Before initiating a mechanical lift transfer, the PTA's FIRST action should be to:
Answer: Verify the lift's weight capacity rating
Verifying the mechanical lift's weight capacity before use is a mandatory safety check to ensure the equipment can safely support the patient's body weight.
A tilt-in-space wheelchair differs from a reclining wheelchair because tilt-in-space systems:
Answer: Rotate the entire seating system while maintaining the seat-to-back angle
Tilt-in-space systems rotate the whole seating unit together, preserving the hip angle and reducing shear forces, unlike reclining systems that open the seat-to-back angle.
Which wheelchair type is MOST appropriate for a patient with strong upper extremities who prioritizes independent self-propulsion?
Answer: Ultra-lightweight manual wheelchair
An ultra-lightweight manual wheelchair requires the least propulsion energy due to its reduced weight, making it ideal for active patients with good upper extremity strength.
