A patient diagnosed with bipolar disorder becomes hyperactive after discontinuing lithium. The patient threatens to hit another patient. Which comment by the nurse is appropriate?

Rationale: A. This approach is confrontational and accusatory, which may escalate agitation in a hyperactive or manic patient. B. This response sets clear limits in a calm, supportive, and non-threatening manner, while also offering assistance with impulse control. C. This statement is shaming and could escalate aggression rather than de-escalate the situation. D. This is a threat rather than a therapeutic intervention, and it may increase the patient's agitation or resistance.
