A nurse in an acute mental health facility is caring for a client who suddenly jumps out of her chair and begins shouting angrily at the other clients. The client appears tense and is pacing rapidly. Which of the following therapeutic responses should the nurse use first?

A. "If you don't stop shouting I have to call security.": This response is punitive and may escalate the client’s agitation. Threatening the client can trigger further aggression and compromise safety, making it inappropriate as a first therapeutic intervention. B. "I can see you're upset. Let's step into the hallway and talk privately.": This response demonstrates a therapeutic approach by acknowledging the client’s emotional state, de-escalating the situation, and removing environmental triggers. It prioritizes safety for the client and others while encouraging verbal expression of feelings. C. "Why are you yelling at the others? What happened to cause this?": Asking “why” questions during acute agitation can be perceived as confrontational, increasing frustration and possibly aggression. It does not address immediate safety or help the client regain control of emotions. D. "You need to calm down before someone gets hurt.": This directive focuses on compliance and external behavior rather than validating feelings or de-escalating tension. While safety is important, a confrontational command may exacerbate agitation rather than promote therapeutic engagement.
