A nurse is caring for a client who is to undergo a total knee arthroplasty. Which of the following actions should the nurse take when participating in the informed consent process?

Informed consent is a legal and ethical process that requires the patient to receive adequate information, understand that information, and make a voluntary, uncoerced decision. The nurse's specific role in the informed consent process is to witness and verify that the client is signing voluntarily and is not being pressured or coerced — this is the function captured by verifying the client is giving consent voluntarily. The responsibility for providing a detailed explanation of the procedure, its risks, benefits, and alternatives — including what may happen without treatment — belongs to the surgeon or treating provider, not the nurse. Therefore, the option stating the nurse should inform the client of the possible outcome if she does not receive treatment describes the physician's duty, not the nurse's witnessing role. Explaining the exact amount of postoperative pain is speculative and also falls outside the nurse's consent role. Disclosing the names of all health care providers participating in surgery is not a standard requirement of the informed consent process. A nurse who witnesses consent must confirm the client's identity, competence, comprehension, and voluntariness — not deliver the substantive medical disclosure.
