A client who is experiencing a severe level of anxiety reports a racing heartbeat, dizziness, and expresses a sense that something dreadful will happen. The nurse observes the client pacing and waving hands rapidly. Which action should the nurse take?

A. Identifying triggers may be beneficial, but the client is currently in a state of severe anxiety, and immediate intervention to address the symptoms is needed. B. Exploring past behaviors can be addressed later; the immediate focus should be on managing the acute symptoms of anxiety. C. Attempting to distract the client can be helpful, but providing reassurance and addressing safety concerns take precedence. D. Speaking calmly to the client and providing assurance of safety is an appropriate first step in managing severe anxiety. Once the client is more settled, other interventions can be explored.
