A nurse is caring for a client who has signed an informed consent form to receive electroconvulsive therapy (ECT). The client states to the nurse, "I'm not sure about this now. I'm afraid it's too risky." Which of the following responses should the nurse make?

A. "Perhaps you think the ECT is dangerous, but I've seen it have good results." This response is dismissive of the client's concerns and implies that the nurse knows better than the client. B. "You have the right to change your mind about this procedure at any time." This response respects the client's autonomy and informs them of their rights. C. "Everyone gets a little nervous about this procedure as the time for it approaches." This response minimizes the client's feelings and assumes that they are experiencing normal anxiety. D. "Your doctor wouldn't have suggested ECT if they didn't think it would help you." This response shifts the responsibility to the doctor and does not address the client's fears.
