NRSG 3302 TEST QUESTIONS AND 100%
CORRECT ANSWERS!!
How does Rh alloimmunization occur?
mom is Rh-, baby is Rh+.
mom develops antibodies against Rh+ so future Rh+ babies will have hemolytic anemia
(sensitized)
What antibodies are produced initially during Rh alloimunization?
IgM
What antibodies develop during the second pregnancy when the mother is sensitized to
Rh?
IgG —> result in the hemolytic anemia of newborn
What does a positive Coombs test in a newborn mean?
Mother has been sensitized to Rh
What are the inventions for Rh incompatibility?
Monitor pregnancy
If suspected hemolytic anemia of newborn = early birth, intrauterine transfusion to fetus,
exchange transfusion of newborn
What are the goals of managing Rh incompatibility
Prevent sensitization
Treat isoimmune disease is sensitization has previously occurred
When is rhogam given to a Rh - mother with negative titer?
, 28 weeks prophylactically for all
2nd dose within 72 hours of birth if newborn is found to be Rh+
What situation is rhogam given?
Anytime there is mixing of fetal/maternal blood
Ex: invasive testing, abortion, trauma, birth
What is ABO incompatibility?
Mom is O and fetus is A,B, or AB
Maternal antibodies cross placenta to attack newborn
What is seen in the newborn when Rh or ABO incompatibility occurs?
Jaundice, mild anemia and hemolysis of fetal RBCs
Can ABO incompatibility be treated antepartally?
No
Is Rh or ABO incompatibility more severe?
Rh
What are the neonatal risks associated with HSV?
Spontaneous abortion
PTL
IUGR
Neonatal infection
When is HSV most likely be transmitted vertically?
When lesions are present
If lesions are present during labor, what should be the intervention?
