A client is admitted to the mental health unit and sits in the corner of the day room. When the nurse begins the admission assessment interview, the client is guarded, suspicious, and resists talking. Which action should the nurse implement?

A. Involving another nurse might not necessarily address the client's guarded and suspicious behavior. B. Documenting the behavior is important for the client's records, but it doesn't address the immediate need for assessment. C. Postponing the interview might not resolve the client's guarded behavior and could delay necessary assessment. D. Attempting to ask the client simple questions allows for a non-threatening approach and might gradually build rapport, encouraging the client to engage in conversation.
