Sagot :
The nurse should prepare to administer rhogam after amniocentesis.
what is amniocentesis?
A procedure where amniotic fluid is sampled with a hollow needle placed inside the uterus to check for anomalies in the developing fetus
Amniotic fluid and cells from the uterus are removed during amniocentesis for testing or treatment. During pregnancy, an embryo is encased in and shielded by amniotic fluid.
Red blood cells have the hereditary protein known as the Rh factor on their surface. A foetus has a minimum 50% chance of becoming Rh positive if both the mother and father are Rh positive. When a mother has Rh-negative blood and her child has Rh-positive blood, there is Rh incompatibility. A woman is at risk of developing maternal antibodies against red blood cell Rh antigens known as Rh sensitization if the red blood cells of a Rh positive foetus enter their Rh negative mother's blood flow during pregnancy.
Fetal Rh positive red blood cells may enter the Rh-negative mother's circulation during labour and delivery, as well as in cases of fetomaternal haemorrhage brought on by miscarriage, abdominal injury during pregnancy, ectopic pregnancy, induced abortion, invasive pregnancy procedures, and miscarriage. Rh sensitization usually does not cause issues during a Rh-negative woman's first pregnancy. Rh isoimmunization, a process that can lead to a condition known as Rhesus disease or hemolytic disease of the foetus and newborn, can occur in a subsequent pregnancy with an Rh positive foetus because the formed antibodies can cross the placenta and attack the fetus' red blood cells.
RhD immune globulin (RhoGam) is given to Rh negative patients who are not sensitive to Rh antigens in order to prevent maternal Rh sensitization.
