A client in the psychiatric unit is experiencing severe anxiety—they are trembling, pacing, and saying, "I can’t think straight. I feel like something terrible is going to happen." Which of the following is the most therapeutic response by the nurse?

"You need to stop thinking this way. Nothing bad is going to happen."

"Let’s sit together here quietly. I’ll stay with you until you feel more in control."

"Try to calm down. You're safe here, so there’s nothing to worry about."

"Why are you so anxious? Can you tell me what triggered this feeling?"
