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?

Rationale: A. Match the client's blood type with the type and cross match specimen: While matching blood types is important, autologous transfusions use the client’s own blood, making crossmatching less critical. This step doesn't confirm the identity of the client receiving the blood. B. Ensure that the client's identification band matches the number on the blood unit: This is the safest and most accurate method to confirm that the blood product belongs to the correct client. The ID band and blood unit must match exactly to prevent transfusion errors. C. Confirm the provider's prescription matches the number on the blood component: The prescription ensures the correct blood product is ordered, but it doesn't verify client identity. This step should follow positive client identification, not replace it. D. Ask the client to state his blood type and the date of the blood donation: Clients may not recall this information accurately, and relying on verbal confirmation can lead to errors. Always verify using the ID band and blood label.
