An individual with which of the following blood types can receive all types of blood?
AB positive
A positive
B negative
O negative
The Correct Answer is A
a. AB positive: Individuals with AB positive blood are universal recipients. They have A and B antigens on their red blood cells but no antibodies (anti-A or anti-B) in their plasma. Therefore, their body will not reject blood types A, B, AB, or Rh positive or negative.
b. A positive: Individuals with A positive blood can only receive A positive or O positive blood. Their plasma contains anti-B antibodies, which would attack blood types B and AB.
c. B negative: Individuals with B negative blood can receive B negative or O negative blood. Their plasma contains anti-A antibodies, which would attack blood types A and AB. The Rh factor is another compatibility consideration, but the question specifies positive.
d. O negative: Individuals with O negative blood are universal donors but not universal recipients. Their red blood cells lack A and B antigens, so they can be donated to anyone. However, their plasma contains anti-A and anti-B antibodies, so they can only receive O negative blood.
