Final Answer:
The most appropriate response by the nurse would be: "This must be a very difficult time for you."
Step-by-step explanation:
The most appropriate response by the nurse would be: "This must be a very difficult time for you."
Option 2, "This must be a very difficult time for you," is the most appropriate response as it acknowledges the client's feelings and expresses empathy without making assumptions or dismissing the client's emotions. It opens the door for further discussion and allows the client to share their thoughts and feelings, fostering a supportive and understanding therapeutic relationship. Responses that invalidate or minimize the client's emotions, such as option 1 and option 3, may not effectively address the client's needs. Option 4, while seeking information, might come across as confrontational and may not be the most sensitive approach in this context.
