In a psychiatric unit, which activity is most suitable for a client with bipolar disorder demonstrating pressured speech and constant need for attention?

The most suitable activity for a client with bipolar disorder demonstrating pressured speech and a constant need for attention is engaging in a physical, interactive game like ping-pong. This choice allows for a high-energy activity that can help channel the client's excess energy in a productive manner while providing immediate feedback and engagement. The fast-paced nature of ping-pong can keep the client occupied and may help to reduce the intensity of their need for constant interaction in a less structured setting.

Additionally, the social aspect of ping-pong can satisfy the client's need for attention in a controlled environment, as the game involves interaction with others, which can help in managing their behavioral impulses. This choice promotes physical activity, encourages socialization, and may support the management of their symptoms better than less stimulating activities such as reading or board games.
