Step-by-step explanation:
The nurse aide should clean the client and take them to dinner as soon as possible. It is important to prioritize the client's comfort and dignity and to address their immediate needs, such as cleaning up after becoming incontinent. Delaying dinner until after the client has cleaned and changed themselves may cause further discomfort and inconvenience for the client. Hence, option (B) is the most appropriate course of action in this situation.
