The nurse is caring for a client diagnosed with catatonia. Which of the following should be a priority action by the nurse?

The correct answer is D: Offer small, frequent fluids throughout the day. This is the priority action because clients with catatonia may be at risk for dehydration due to reduced fluid intake. Hydration is essential for overall health and well-being. Scheduling a therapeutic group session (A) may not address the immediate physiological needs of the client. Encouraging the client to walk in the hallway (B) may be beneficial, but ensuring hydration takes precedence. While encouraging verbalization of feelings (C) is important for communication, hydration is a more urgent need.
