Final answer:
Assistance should be requested for a transfer when (c) the client has a history of recent falls and unsteady gait, as it implies a greater risk during the transfer.
Step-by-step explanation:
The practical nurse (PN) should request assistance when moving a client who has a history of recent falls and unsteady gait. This clinical finding suggests a higher risk of instability and potential harm during the transfer process.
While the client's blood pressure and respiratory rate being within normal limits and their own readiness for the transfer are positive signs, the history of falls is a critical factor, as it indicates the client may require additional support to ensure a safe transfer from the bed to the wheelchair.
