Final Answer:
The nurse should choose option A and pull up a chair to sit beside the client as a supportive and empathetic response to the emotional distress.
Step-by-step explanation:
Option A involves providing immediate support and comfort to the client by physically being present and showing empathy. Sitting beside the client communicates a willingness to listen and be present without pressuring the client to talk. It acknowledges the client's emotions and offers a non-verbal form of support. Reviewing the client's record (Option B) may not be the most immediate or empathetic response in this situation. Providing privacy (Option C) is essential, but sitting with the client addresses the emotional need for support. Asking the client why she is crying (Option D) may be appropriate but should be done after establishing a supportive presence.
The correct option is A.
