Nadia: Hi, can I speak with you?
Sure! What do you need?
Nadia: I heard about what happened with Mr. Liu. I just feel so bad that I came in to see him earlier and didn't realize what was going on.
Nadia: I can't help but feel like it's my fault that Mr. Liu had to go through that. It had to be pretty scary when his breathing got worse, and if I'd noticed that his chest tube was clamped when I brought him his water, maybe I could have mentioned it to you and he would have gotten help immediately.What is the most appropriate response to Nadia in this situation?

A) "Nadia, it's understandable that you feel concerned, but it's not your fault. Let's focus on ensuring Mr. Liu receives the care he needs now."
B) "Nadia, blaming yourself won't change what happened. Let's concentrate on supporting Mr. Liu's recovery moving forward."
C) "Nadia, everyone plays a part in patient care. Your concern shows your dedication. Let's work together to prevent similar incidents in the future."
D) "Nadia, it's important to learn from situations like these. Let's discuss how we can improve our communication and observation skills."
