Which blood types can be used for transfusion for a client with type A negative blood?

The correct choice indicates the most suitable blood types for a transfusion to a client with type A negative blood. Individuals with A negative blood can safely receive red blood cells from donors who have A negative or O negative blood types. This compatibility arises due to the presence or absence of specific antigens and antibodies in the blood.

Type A negative has A antigens on the surface of red blood cells and does not have the Rh (Rhesus) factor, meaning the recipient's immune system could react against additional antigens if they are present. Therefore, O negative blood is a universal donor for red blood cells, as it lacks A, B, and Rh antigens, making it safe for transfusion to A negative recipients. Similarly, A negative blood, which has A antigens but not Rh factors, can safely receive A negative blood.

This option aligns with the principles of blood transfusion compatibility, ensuring that the client's immune system remains safe during the process.
