A nurse in an acute care setting is preparing to administer medications to a client. Which of the following information should the nurse obtain to identify the client?

a. To ensure accurate identification and avoid medication errors, the nurse should use at least two patient identifiers, such as the client's full name and date of birth. This information is critical in verifying that the right patient receives the correct medication. b. While a telephone number could potentially be used as an identifier, it is not typically used in acute care settings due to the possibility of errors or outdated information. It is also not practical as a primary means of patient identification. c. Knowing the client's room number is important to confirm the correct location of the client in the acute care setting. This helps ensure that the nurse administers the medications to the correct client. However, the room number alone is not sufficient for accurate client identification. Room numbers may change, and multiple clients may share the same room. Relying on the room number alone can lead to errors. d. While the client's diagnosis is important for understanding their medical condition and providing appropriate care, it is not specifically required for identifying the client when administering medications.
