Step-by-step explanation:
To help redirect the attention of a client with Alzheimer's disease who is mumbling incoherently and rambling in a confused manner, the nurse should encourage the client to engage in activities that stimulate their cognitive function and focus their attention. Playing cards with another client or participating in a game of charades can help keep the client mentally engaged and redirect their attention. These activities require interaction and concentration, which can help reduce confusion and improve the client's overall well-being.
