What are the sequence of events that happen to cause erythroblastosis fetalis?
Erythroblastosis fetalis occurs when an Rh-negative mother is sensitized to the Rh antigen from an Rh-positive fetus during pregnancy or delivery, leading to the mother's immune system producing antibodies against the Rh antigen. In subsequent pregnancies with Rh-positive fetuses, these antibodies can cross the placenta and attack the fetal red blood cells, leading to hemolysis and potentially severe complications for the fetus.
How does rh negative blood types affect pregnancy?
Having a negative rh blood type can seriously affect pregnancy and should be monitored closely. The possible incompatibility between the mother and the fetus could result in the mothers antibodies attacking the fetus as if it were a virus. This can be prevented by a shot roughly 28 weeks into the pregnancy.
Rh- mothers pregnant with Rh+ babies usually have a problem with the first baby.O a. TrueO b. False?
True. Rh-negative mothers who are pregnant with Rh-positive babies can develop antibodies against the baby's blood, leading to hemolytic disease of the newborn in subsequent pregnancies.
How is anti e acquired?
Anti-E antibodies are acquired through exposure to foreign RBC antigens during pregnancy, blood transfusions, or organ transplants. These antibodies develop in response to incompatible red blood cell antigens of the Rh system, such as the D antigen. Anti-E is one of the many possible Rh antibodies that can be produced.
Under what circumstances can problems with the Rh factor arise?
Problems with the Rh factor can arise during pregnancy when an Rh-negative mother is carrying an Rh-positive baby. If the mother's immune system produces antibodies against the Rh factor of the baby, it can lead to hemolytic disease of the newborn in subsequent pregnancies, causing complications for the baby.
Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Under what conditions might a person with Rh-blood develop Rh antibodies?
The first time an Rh- patient receives blood from an Rh+ donor, the Rh- patient will develop Rh agglutinins (agglutinins=antibodies) in the blood plasma. If the patient receives another Rh+ donation, it will cause agglutination, or clumping of the blood. The red blood cell membranes become leaky and hemoglobin pours into the blood. A possible cause is kidney failure due to excess hemoglobin at filtration sites.
With a Rh plus mother and a Rh- fetus will either develop antibodies against Rh antigens?
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
Will blood type O clump or not with anti RH antibodies?
Blood type O will not clump with anti-Rh antibodies because the Rh factor is a separate antigen from the A and B antigens that determine blood type. Type O blood is characterized by the absence of A and B antigens, and the presence or absence of the Rh factor (positive or negative) is independent of the A and B antigens. Therefore, if the blood type is O and Rh-negative, it will not react with anti-Rh antibodies.
Can A negative blood type receive positive blood type?
An Rh negative recipient may receive Rh positive cellular blood products IF the recipient does not have preexisting Anti-D antibodies present in their plasma, is not a female of child bearing age/capable of becoming pregnant and/or there is an emergent need for blood components (trauma, etc.) and Rh negative products are not available. If Rh positive products are administered to an Rh negative recipient, Rh positive components may continue to be administered until anti-D antibodies are detected on pre-transfusion screening tests. If Rh positive platelets are administered to an Rh negative recipient, Rh Immune Globulin (e.g., RHoGam) may be administered to prevent sensitization in the recipient.
How does Rh factor affect a fetus?
When a mother is Rh negative and her baby is Rh positive, she may develop antibodies to the baby's blood that will cause it to hemolyze
Does a RH negative individual normally contain anti RH antibodies?
No. Rh-antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have rh-negative blood you got AB blood. Your RH-antibodies then work to attack the foreign substance, the RBCS. In the fetus, loss of RBCS means the rise of bilburin and could eventually lead to brain damage or (kernictous), and also have low muscle tone(hypotonia)
Why does a transfusion reaction not occur the first time a rh positive patient is exposed to rh negative blood?
the transfusion reaction doesn't occur the first time an Rh+ patient is exposed to Rh- blood because the Rh+ patients body hasn't created the antibodies needed to attack the Rh- blood that it comes in contact with. the second time the Rh+ patients body comes in contact with Rh- blood, it will have the antibodies necessary to fight against Rh- blood.
What creates Rh disease?
If an Rh negative woman is pregnant with an Rh positive fetus, her body will produce antibodies against the fetus's blood, causing a disease known as Rh disease
How is it that an incompatible ABO blood group will generate a transfusion reaction the first time a transfusion is given while Rh incompatibility creates a problem the second time?
The antigens of the ABO system are mimicked by bacterial cell walls. So if your body does not actively suppress antibodies to them (because you have them) then antibodies will form over time to the ones you so not have (A or B or both). The rhesus factor (Rh) is not mimicked in nature and so antibodies are not formed in Rh negative people until after an exposure - usually when an Rh negative women carries an Rh positive child. If the person is Rh positive then antibodies will not form no matter what.
What happen when a pregnant rh- woman delivers a rh plus baby?
The Rh factor is associated with issues in pregnancies. Rh- (Rh- negative) people do not automatically carry anti- Rh antibodies but the immune system will manufacture them if exposed to Rh+ blood. If the Rh- negative mother has not been exposed to Rh+ blood the first pregnancy will progress without complications. However upon delivering her first child the severing of the placenta from the uterus will expose the Rh- negative mother to the Rh+ blood stimulating the production of Rh+ antibodies. If the Rh- woman becomes pregnant with another Rh+ child her antibodies will traverse the placenta and obliterate the infants erythrocytes (RBCs). The baby will develop a condition known as erythroblastosis fetalis which may result in death if untreated prior to birth.
What causes the production of Rh antibodies?
Exposure to the Rh (or D) antigen. Most common in mothers who are Rh- who have a child that is Rh+. The mothers immune system will produce Rh antibodies and the blood cells of the NEXT Rh+ baby could be attacked during birth. Rh- mothers are given Rhogam to prevent this from happening. I know this is more than you asked for but every test question dealing with Rh asks something about this it is commonly called hemolytic disease of the newborn
