NBCOT exam practice question: Domain 03: Select and Manage Interventions

Domain 03: Select and Manage InterventionsDifficulty 3/5

A client uses a wheelchair and cannot enter their bathroom. Which modification should the OTR evaluate first?

  1. AWidening the doorway to the clear width a wheelchair requires
  2. BReplacing the tub with a roll-in shower and a hand-held sprayer
  3. CAdding a raised toilet seat to reduce the height of the transfer
  4. DInstalling a vertical grab bar beside the toilet for transfer support
Show answer and rationale

Correct: A. If the wheelchair cannot pass the doorway, nothing inside the room can be used. Access precedes every in-room modification.

  • D — A grab bar is useless if the client cannot get into the room.
  • B — A roll-in shower is inaccessible behind a too-narrow doorway.
  • C — Seat height does not address the access barrier.
