blood typing Flashcards
study guide for lecture exam #2
what are the 4 blood types within the ABO Blood Group?
- A
- B
- AB
- O
If people are blood type A, what do they have?
their erythrocytes have A antigens on their erythrocyte membrane surfaces
if people are blood type B, what do they have?
their erythrocytes have B antigens
if people are blood type AB, what do they have?
their erythrocytes have both A and B antigens
if people have neither A nor B antigens, what blood type does that make them?
blood type O
how is the Rh Blood Group classified?
according to the presence or absence of Rh antigen
how do you determine if a person is a part of the Rh blood group?
if they have a Rh D antigen present on their erythrocyte
what are the two types within the Rh Blood Group?
- Rh positive (Rh+)
- Rh negative (Rh-)
how is the Rh group determined when identifying a patient’s blood type?
the Rh group is designated by adding the word positive (+) or negative (-) to the ABO type
what does it mean when a patient’s blood type is A positive (A+)?
A positive (A+) means ABO group A blood with the Rh antigen present
what does it mean when a patient’s blood type is AB negative (AB-)?
AB blood without the Rh antigen
which blood type is referred to as the universal donor?
blood type O
which blood type is referred to as the universal recipient?
blood type AB+
regarding the Rh factor, why is the compatibility between the mother and the fetus so important?
if an Rh+ baby is born to an Rh- mother, the mother can be exposed to the baby’s Rh+ cells which will cause the mother’s immune system to create anti-Rh antibodies. Because of this, if the mother becomes pregnant with another Rh+ baby, the Rh antibodies that were produced can destroy the fetal RBCs
why is it important to match donated blood to compatible blood types of the recipient?
to avoid transfusion reactions
