Exam 1 - Rh Incompatibility Flashcards
Exam 1
foreign substances that invade the body
Antigens
made by your body to identify a specific antigen
Antibodies
antibodies made rapidly during primary immune response
IgM
antibodies made for immune “memory” and secondary immune response
IgG
Rh
protein found on blood cells, naturally occurring in some people
What women are at risk for Rh incompatibility?
Only women who are Rh-
Why are women at risk for Rh incompatibility?
An Rh- woman will make anti-D antibodies if their baby is Rh+; will use those antibodies in next pregnancy, which can cross the placenta
T/F: The first baby is safe from antibodies made by mom.
True.
SAB means what?
Spontaneous abortion
TAB means what?
therapeutic abortion - chosen / elective
placenta coming away from the uterus is called what?
placental abruption
non-descript bleeding that does not endanger the pregnancy is called what?
Antepartum bleeding
What are the main risk factors for developing Anti-D Antibodies?
Blood transfusion
Needles
Abdominal trauma
Abortion
Placental abruption
Antepartum bleeding
Normal birth
Hemolytic disease of the newborn (HDoN) means what?
Hemolysis of RBCs of the baby
Name the 4 complications of HDoN
(1) intrauterine fetal demise (IFD)
(2) Cardiac abnormalities
(3) Hydrops fetalis
(4) Newborn on-physiologic jaundice
Cardiac failure and subsequent fluid buildup in tissue is called what?
Hydrops fetalis
What is a serious consequence of kernicterus?
Brain development consequences / issues
If a woman is Rh-, what medication is she given?
Rhogam
What is the screening test called for pregnant women?
Indirect Coombs-Test
How is Rhogam delivered?
IM Injection
When do women receive Rhogam if they are Rh- and why?
28 weeks; placenta is well-developed; fetal blood supply is bigger
If there is trauma or suspected fetomaternal hemorrhage, what do we do?
Re-dose Rhogam and make sure there is enough protection
What is the nursing role in Rh incompatibility?
(1) Education re: Rh factor and isoimmunization
(2) Anticipate administrating Rhogam
(3) collect and send umbilical cord blood to lab
(4) manage neonates in NICU for complications of Rh incompatibility
Which newborns are screened for blood type and Rh factor?
All
