Which step should be performed after lowering the bed to assist a resident in ambulation?

Locking the wheels of the bed is an essential safety step after lowering the bed to assist a resident in ambulation. This action prevents the bed from moving unexpectedly and reduces the risk of falls or injuries to both the resident and the caregiver during the process of helping the resident to stand and walk. Ensuring the bed is stable provides a secure base from which the resident can safely transition from lying down to a standing position.

Other steps like standing on the person's strong side or preparing ambulation devices are important, but they should come after ensuring the bed is securely locked. Doing nothing until the resident is ready does not provide the necessary support and could compromise safety, as it disregards the importance of maintaining a controlled environment during ambulation. Each of these steps is part of a comprehensive approach to ensuring the resident's safety and comfort, but securing the bed is the fundamental first action after adjusting it to a proper height for assistance.
