The nurse observes a client with a history of psychosis repeatedly looking to the side and mumbling responses to no one present in that direction. Which comment is best for the nurse to make?

A. Telling the client that the voices they are hearing are not real may invalidate their experience and could increase their distress or resistance to the nurse's intervention. B. While discussing strategies for the next occurrence might be helpful, it does not address the immediate situation or acknowledge the client's current experience. C. Asking the client to focus on something else may be perceived as dismissive and may not effectively engage them in conversation or provide support. D. Acknowledging that the client appears to be speaking with someone validates their experience without confirming the reality of the voices. This comment encourages the client to express themselves and provides an opening for further communication, allowing the nurse to assess the situation more effectively.
