PCM FINAL EXAM 2025 QUESTIONS
AND ANSWERS
Seat depth too long - ANS increased pressure on popliteal area
Seat Depth too short - ANS decreased trunk stability
seat height too high - ANS insufficient trunk support
seat height too low - ANS difficult with transfers
seat width too wide - ANS user will have difficulty reaching the hand rims to propel the
wheel chair
seat width too narrow - ANS excessive pressure on the greater trochanters
leg length too long - ANS causes pressure on posterior aspect of distal femur

, back height too low - ANS decreased trunk stability
armrest height too high - ANS user will have difficulty reaching hand rims
possibly greater pressure on olecranon
armrest height too low - ANS posture issues, inadequate balance, and difficulty pushing from
sit to stand
difference between reclining and semi-reclining w/c - ANS semi-reclining goes back to 30 deg
reclining w/c goes back horizontal and rear wheels need to be placed more posterior to prevent
wheelchair from tipping backwards
tilt-in-space w/c - ANS seating position angle is maintained and the whole seat tilts back to
allow for pressure relief
used for clients unable to regularly perform pressure relief
externally powered w/c?
what controls them? - ANS powered by one or more deep-cycle batteries
various controls such as hand control, chin, head, tongue, mouth, sip and puff
sports/recreational - ANS customized for sports
light weight, strong, highly maneuverable,
tilted canted wheels
standard adult w/c - ANS persons <200 lbs
limited use on rough surfaces
