Kristen needs a blood transfusion and she think she has a AB

Kristen needs a blood transfusion and she think she has a AB blood type. As her friend, Mac has an AB^+ blood type both figure can donate blood for her. When they get to the dine, Mac\'s blood is is with that of Kristen. Select the concert explanation that they are given explain this outcome. O Mac\'s blood type would trigger the formation of anti-Rh which would stay blood and react with the next transfusions cause blood hemolysis in her O Mac\'s AB blood type would attack the Antigen of Kristen\'s blood O Kristen\'s AB blood type would attack the A antigen of Macs blood O Kristen\'s blood type would trigger the formation of anti-Rh which would stay in her blood and react with the next transfusion s cause blood hemolysis

Solution

The Kristen\'s blood is AB- and Mac\'s blood is AB+. This means that Mac\'s blood contains Rhesus antigen while Kristen does not. Inusion of a person carrying Rhesus negative blood type with Rhesus positive blood type will result in faulty agglutination. If Kristen is infused with Mac\'s blood, she will produce anti-bodies against Mac\'s blood and hence an immune response will be generated in Kristen\'s blood against Mac\'s blood. This will enahnce clumping of blood due to mis-match of blood antigens.

This suggests that choice 4 is correct.
