A client admitted to the psychiatric unit diagnosed with major depression wants to sleep during the day, refuses to take a bath, and refuses to eat. Which nursing intervention should the nurse implement first?

A. Assessing the client's ability to communicate is important but not the first step in addressing the immediate concerns related to depression. B. Establishing a structured routine helps provide stability and encourages engagement in daily activities, which is essential for managing depression. C. Arranging a meeting with the family is important for support but does not immediately address the client’s current refusal to eat or bathe. D. Administering medication is important but should follow the implementation of supportive measures like establishing a routine that can improve the client's overall engagement and well-being.
