Final answer:
The nurse is using the therapeutic technique of reflecting by restating the client's concern to facilitate deeper insight.
Step-by-step explanation:
When the nurse responds to the client's question by saying, “You aren’t sure if you should leave your husband?” the nurse is using the therapeutic technique of reflecting.
This technique involves the nurse listening to the client's concerns and then restating or summarizing what has been said, in order to encourage further exploration of the client's feelings and thoughts.
This helps the client to hear their own thoughts and possibly gain insight into their own feelings and behaviors, facilitating a deeper understanding of their situation without direct advice from the nurse.
