The nurse notes that a client with depression has been more withdrawn and noncommunicative during the past two weeks. Which Intervention is most important to include in the updated plan of care for this client?

A. Encouraging the client to participate in group activities may be beneficial but may not address the immediate need for increased communication and engagement. B. Scheduling a daily conference with the social worker may provide support but may not directly address the client's withdrawal and noncommunicative behavior. C. Engaging the client in non-threatening conversations is important to assess the client's current emotional state, understand the reasons for withdrawal, and provide support and encouragement for communication and interaction. D. Encouraging the client's family to visit more often may be helpful for social support, but it may not address the underlying issue of the client's withdrawal and noncommunicative behavior.
