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?

Choice A reason: Telling the patient to stop thinking a certain way invalidates their feelings and is not therapeutic. Choice B reason: Offering presence and calm support provides safety and helps reduce anxiety. It is the most therapeutic intervention for severe anxiety. Choice C reason: Telling the patient not to worry may feel dismissive, and in severe anxiety the patient may not be able to process reassurance. Choice D reason: Asking "why" is not effective when the patient is overwhelmed by severe anxiety, as they cannot engage in rational discussion at that moment.
