3. If a hemorrhagic patient with A- blood receives a transfusion but soon dies due to hemagglutination, which of the following would have been possible types of blood she received that initiated the reaction?
*
A. O-, A+, or B+
B. AB+, A+, or O+
C. B-, O-, or AB+
D. A-, O- or A+

That would be my answer as well.

The self RBCs of the patient don't contain the Rh antigen so any blood that is Rh+ appears foreign to the body. Therefore, antibodies bind to the newly transfused blood's Rh antigen and cause the blood to clump, or agglutinate. This can occur because antibodies contain two binding sites so they could potentially bind to two different erythrocytes.

Using POE, we can eliminate the A, C, D, and E because they all contain O- who is the universal donor.

Hopefully that makes sense.
