A nurse is providing education to a client who is scheduled for a left knee arthroplasty. Which of the following statements regarding informed consent indicates client understanding of the teaching?

Informed consent requires that the client voluntarily agrees to the procedure after being informed of its nature, risks, benefits, and alternatives. Stating "Signing this form indicates that I give my permission for the surgery" demonstrates understanding that the signature represents voluntary consent. Ambivalence (A) may indicate inadequate consent — the client may need more information. Requesting more information (C) indicates the client has not yet received adequate teaching. Waiting to speak with the doctor in the OR (D) is too late for proper informed consent.
