A client is admitted to the mental health unit with a bipolar disorder. When seeking to establish a therapeutic relationship and interacting with the client, which comment is best for the nurse to make?

A. This comment may come across as invalidating the client's feelings by assuming overreaction, which could potentially escalate the situation. B. This response acknowledges the client's feelings and invites further exploration, fostering a therapeutic relationship and understanding of the client's experiences. C. While understanding the cause of symptoms is important, it may not necessarily make them easier to handle, and it could divert focus from addressing the client's immediate concerns. D. While encouragement is positive, this comment does not directly address the client's feelings or concerns, which is essential for building a therapeutic relationship.
