A nurse is preparing to administer an autologous blood product to a client. Which of the following actions should the nurse take to identify the client?

A. Confirm the provider's prescription matches the number on the blood component: While verifying the provider’s prescription is important, it does not confirm the identity of the client receiving the blood. Client identification must be confirmed directly at the bedside. B. Match the client's blood type with the type and cross match specimen: Verifying blood type compatibility is essential for transfusion safety, but it does not replace proper client identification. Misidentification could still occur if other verification steps are skipped. C. Ask the client to state his blood type and the date of the blood donation: Clients may not reliably recall these details, and relying solely on self-report is unsafe. Proper identification requires objective verification using official identification methods. D. Ensure that the client's identification matches the number on the blood unit: Correct client identification is achieved by comparing the client’s ID band information with the blood unit number and labels. This step is the primary safeguard to prevent transfusion errors and ensure the right client receives the correct blood product.
