The client is asking why the doctor ordered only red blood cells (packed RBCs) instead of the entire unit of whole blood. The nurse explains that:
1. It is an optimal method of transfusing only the specific component needed by the client.
2. It is the only blood that is left in the blood bank.
3. RBCs are useful for clients who are experiencing a lack of clotting factors.
4. RBCs are useful for preventing transfusion reactions.
It is an optimal method of transfusing only the specific component needed by the client.
Rationale: Using only the component that is needed is a safe and economical use of the blood supply. Using the only blood that is left in the blood bank would never be the rationale for a blood transfusion. Cryoprecipitates, plasma, and platelets are used for replacing clotting factors. RBCs cannot prevent a transfusion reaction.
