What else can I help you with?
Is it true Rh incompatibility between a sensitized Rh woman and an Rh- fetus can cause hemolytic disease of the newborn?

The condition in which rh plus red blood cells of a fetus are attacked by anti-Rh antibodies of the fetus Rh-mother is called?
Heamolytic disease of the newborn or Erythroblastosis Fetalis
What does RH factor stand for?
The Rh- factor is the synonym of "Rhesus factor". Rh factor is a layer of protein that is found outside the Red blood cell (RBC). It was discovered for the first time in Rhesus monkey an inhabitant of Africa, hence the name.
What are some benefits of a vaccination that could desensitize an Rh plus situation?
- Decreased risk in pregnancies with different blood types. - Decrease in Rhesus disease - Allowing easier blood transfusions between Rh+ and Rh-.
Can Rh antibodies of Rh- be detected?
A person who is Rh negative may have antibodies if he or she has been exposed in the past to Rh positive blood. Rhogam will prevent this sensitization in a pregnant woman with negative blood carrying an Rh positive baby.
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
IF a mother is HR negative and father is HR positive why is second pregnancy a problem?
If the mother is Rh negative and the father Rh positive there is a possibility that the unborn baby will be Rh positive as well. If the baby is Rh positive than the mother (who is Rh negative) has antibodies made for Rh positive substances which would include the baby. Basically the mothers body will attack the baby because it is not a match with her body. Commonly this is not as much of a problem with the first baby because the body does not build up the resistance to the first child but the second child will often run into complications because the body has built up antibodies against the second child's Rh positive blood. This is often called Rhesus disease or Rh disease.
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.
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.
Give reasons why fetal blood must not mix with maternal blood?
Number one: If you are RH- and your baby RH+, and your blood mixes with your baby's, it could become sensitized. Your body could begin producing antibodies to the RH+ blood. If these antibodies get to an unborn baby, they can begin killing off the baby's red blood cells. This is called RH disease. It is rare for it to affect a first baby, but if the mother becomes sensitized and produces antibodies to RH+ blood, it could cause problems for future babies. RH disease is very serious; however, recent medical advances allow 90% of babies with RH disease to survive (March of Dimes).
What happens in the blood of an RH negative who is exposed to RH positive blood?
If an Rh negative person is exposed to Rh positive blood, their immune system may produce antibodies against the Rh antigen. Upon subsequent exposure to Rh positive blood, these antibodies can attack and destroy the Rh positive red blood cells, leading to a condition called hemolytic disease of the newborn (HDN) in pregnant women or a transfusion reaction in non-pregnant individuals.
What Rh blood types must the mother and fetus have before HDN can occur?
Hemolytic Disease of the Newborn (HDN) typically occurs when an Rh-negative mother carries an Rh-positive fetus. In this scenario, if the mother is Rh-negative and the fetus inherits the Rh-positive factor from the father, the mother's immune system may produce antibodies against the fetus's Rh-positive red blood cells, leading to HDN. Therefore, for HDN to occur, the mother must be Rh-negative and the fetus must be Rh-positive.
