Preparation for assisting a client involves greeting and identifying the client, explaining the procedure, adjusting the position of IV pole, tubes, and catheters, providing the client with hearing aid and glasses if used, lowering the head of the bed to the lowest position, locking the wheels of the bed, placing the pillow near the headboard, and assisting the client to supine position with knees flexed so that soles of one or both feet are flat on the bed.
