A nurse on an inpatient mental health unit is admitting a client who has panic-level anxiety. After showing the client to his room, which of the following nursing actions is most therapeutic at this time?

A. Resting in bed may be helpful later, but it does not provide the immediate reassurance and support needed during a panic attack. B. Remaining with the client provides reassurance, safety, and emotional support during a panic attack, which is essential for de-escalation. C. Having the client join a therapy group during a panic attack would be overwhelming and inappropriate. D. Administering a sedative may be considered later but should not be the first intervention, as verbal support and reassurance are the priority during a panic attack.
