A nurse opens a unit-dose of a prescribed medication prior to administering it to a client. The client refuses to take the medication. Which of the following actions should the nurse take?

A. An incident report is not necessary in this case, as the client has the right to refuse medication, and no error occurred. B. The ethics committee is not required to be involved unless there is a complex ethical dilemma, which is not the case here. C. Reporting the incident to the provider is appropriate to inform them of the refusal, which could impact the client's treatment plan. D. Returning an opened unit-dose medication to the cart is not allowed due to contamination risk and disposal protocols.
