A nurse is preparing to administer a blood transfusion to a client. Which of the following actions should the nurse take first?

The correct answer is A: Verify the clientÔÇÖs identity with two identifiers first. This is crucial to prevent potential errors and ensure the right blood is given to the right patient. By confirming the client's identity with two identifiers (e.g., name and date of birth), the nurse establishes a solid foundation for safe administration. Checking blood type compatibility (B) is important but comes after confirming the client's identity. Starting the transfusion at a rapid rate (C) without proper checks can lead to adverse reactions. Obtaining baseline vital signs (D) is essential but should follow the verification of the client's identity to prioritize safety.
