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. "I can only give medical information to your child because the client is an adult.": This response respects the client's autonomy and confidentiality as an adult and upholds legal and ethical principles regarding patient privacy. B. "I'm sorry, but your child's medical information is none of your business.": This response is dismissive and disrespectful, violating the client's right to privacy and confidentiality. C. "The healthcare provider will share this information with you.": While healthcare providers may share information with family members if the client consents or if it's deemed necessary for the client's care, this response does not address the legal and ethical considerations regarding patient confidentiality and autonomy. D. "I can give you those results as soon as I get them back from the lab.": This response does not address the issue of patient confidentiality and may inadvertently disclose sensitive medical information without the client's consent.
