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?

The correct answer is C: Is your name Sarah Jones? This question helps verify the client's identity by confirming their name, a key identifier for medication administration. Asking about age (A) or room number (B) does not directly confirm identity. Inquiring about a home phone number (D) is not as reliable as the client may provide incorrect information. Other choices (E, F, G) are irrelevant. Thus, confirming the client's name is crucial for accurate medication administration.
