-
Landsteiner
-
Levine
-
Weiner
-
Coombs
Correct Answer
A. LandsteinerExplanation
The ABO blood group system, which classifies human blood into different types (A, B, AB, and O), was discovered by Landsteiner. He conducted experiments in the early 20th century that led to the identification of these blood groups and the understanding of blood transfusion compatibility. His discovery was a significant breakthrough in the field of blood transfusion and laid the foundation for further advancements in blood typing and compatibility testing.Rate this question:

Blood containing neither antigens A nor B is which of the following groups?
-
AB
-
O
-
B
-
A
Correct Answer
A. OExplanation
Blood group O is the correct answer because individuals with blood group O have neither antigen A nor antigen B on the surface of their red blood cells. They have antibodies against both antigens A and B in their plasma. This means that if they receive blood from a donor with antigens A or B, their antibodies will attack and destroy the donor's red blood cells. Therefore, individuals with blood group O are considered universal donors as their blood can be transfused to individuals with any other blood group.Rate this question:

A group AB parent mated with a group O parent. Which of the following are possible in the offspring?
-
Group A
-
Group B
-
Group A and B
-
Group O
Correct Answer
A. Group A and BExplanation
When a group AB parent mates with a group O parent, the possible blood types in the offspring can be either group A or group B. This is because the AB parent can pass on either an A or B allele to the offspring, while the O parent can only pass on an O allele. Therefore, the offspring can inherit either an A allele from the AB parent and an O allele from the O parent, resulting in group A blood type, or they can inherit a B allele from the AB parent and an O allele from the O parent, resulting in group B blood type.Rate this question:

Which blood group system is primarily associated with hemolytic disease of the newborn (HDN)?
-
Kell
-
Duffy
-
ABO
-
Rh
Correct Answer
A. ABOExplanation
Hemolytic disease of the newborn (HDN), also known as erythroblastosis fetalis, is most commonly associated with the Rh blood group system, particularly the RhD antigen. This occurs when an Rh-negative mother is sensitized to the Rh-positive red blood cells of her fetus, leading to the production of antibodies that can cross the placenta and attack the fetal red cells, causing hemolysis. While ABO incompatibility can also cause HDN, it is typically less severe than Rh-related HDN. Kell and Duffy blood group systems are less frequently involved in HDN. Therefore, the Rh system is the most critical in this context.Rate this question:
