Final answer:
The charge nurse would intervene if the new nurse provides incorrect information about electroconvulsive therapy (ECT) as a long-term treatment for chronic depression.
Step-by-step explanation:
The new nurse should provide accurate and reliable information to the client scheduled for electroconvulsive therapy (ECT). The information that would cause the charge nurse to intervene is option d) "ECT is a long-term treatment for chronic depression." This statement is incorrect as ECT is typically used as a short-term treatment for severe depression that is resistant to other forms of therapy. It is important for the nurse to provide correct information to the client to avoid misinformation and potential harm.
