A 22-year-old client is admitted to the hospital in diabetic ketoacidosis (DKA. The client's parent is insisting to know the laboratory test results. Which is the best response for the nurse to provide?

A. Providing lab results to the parent without the client's consent violates the client’s right to privacy under HIPAA (Health Insurance Portability and Accountability Act). B. While the healthcare provider may discuss results, the nurse must first ensure the client has given consent for the parent to receive medical information. C. Since the client is an adult (22 years old), their medical information is confidential. The nurse can only share information with the parent if the client provides explicit consent. D. This response is inappropriate and dismissive, potentially damaging the nurse-client relationship. A professional and respectful explanation should be given.
