EXAM QUESTIONS
QUESTION 1
The two main components important in determining blood type are:
CORRECT ANSWER
Red blood cells and proteins (in the plasma)
RATIONALE: The correct answer focuses on the two main components involved in determining blood type: red blood cells
and the proteins present in the plasma, specifically the ABO blood group antigens and Rh factor. By identifying these
components, individuals can accurately determine their blood type, which is crucial for transfusions and other medical
procedures.

, QUESTION 2
True or False: A one-year old baby will have antibodies present in their blood.
CORRECT ANSWER
True
RATIONALE: A one-year-old baby will have antibodies present in their blood because they received antibodies from their
mother through the placenta during pregnancy, which provide them with temporary immunity against certain infections.
This initial source of antibodies, also known as passive immunity, starts to wane as the baby grows and develops their own
adaptive immune system.
QUESTION 3
True or False: A person with Type A blood will contain antigens for Type A.
CORRECT ANSWER
True
RATIONALE: A person with Type A blood has the A antigen on the surface of their red blood cells, which is a result of the
ABO blood group system. The presence of these A antigens means that the individual's immune system is aware of and
recognizes the A antigen, and therefore, they will contain antibodies against the B antigen, not the A antigen itself, but the
question is asking about the antigens, not antibodies.
QUESTION 4
True or False: A person with Type B blood will contain antibodies for Type A.
CORRECT ANSWER
True
RATIONALE: A person with Type B blood has antibodies against ABO blood group antigens, specifically those found on Type
A red blood cells, which helps prevent an adverse reaction when exposed to Type A blood. This is due to the immune
system's natural defense mechanism, where it produces antibodies against foreign substances it encounters during fetal
development or early life, in this case, the ABO antigens not present on the individual's own red blood cells.
