A nurse is preparing to identify a client prior to medication administration. Which of the following questions should the nurse ask to determine the client's identity?

Choice A rationale: Asking for a home phone number is not an effective method for identifying a patient. Phone numbers can be easily forgotten or mixed up, especially in a hospital setting where a patient may be under stress or experiencing health issues. Choice B rationale: Room numbers can change if the patient is moved, and other patients may have previously occupied the same room. Therefore, room numbers are not reliable identifiers. Choice C rationale: Asking the patient to confirm their own name is one of the most direct and reliable ways to verify their identity. This method respects patient autonomy and privacy while ensuring accurate identification. Choice D rationale: Age alone is not a reliable identifier because it does not distinguish between different patients of the same age.
