Mrs. jones blood typing results showed agglutination with the plasma containing anti - b antibodies only. what is her blood type and what blood can she receive in order to save her life?

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.
