While recovering from a severe illness, a hospitalized patient wants to change a living will, which was signed 9 months ago. Which response by the nurse is most appropriate?

A. This is incorrect because although verifying the presence of a living will in the chart is helpful, it doesn't address the patient's desire to change it. B. This is incorrect because there is no legal limit to how often a living will can be changed; frequency is determined by the patient's needs and preferences. C. This is correct because it acknowledges the patient's request while ensuring that appropriate steps and professionals are involved. A living will can be updated or revoked at any time as long as the individual is mentally competent. D. This is false; living wills are not permanent and can be changed or revoked at any time by the competent patient.
