NUR 325 Exam 5 Study Questions and
Correct Answers
Normal bilirubin level at 24 hours of age ✅2-6 mg/dl
Normal bilirubin level at 48 hours of age ✅6-7 mg/dl
physiologic jaundice ✅begins after 24 hours of age, can be due to decreased fluid
intake &/or possible dehydration, occurs in about 60% of term & all preterm
physiologic jaundice treament ✅evaluate breastfeeding, pump breast milk, make sure
they are getting adequate feeds so they are excreting the bilirubin
pathologic jaundice ✅increases within 24 hours of birth, increases by more than .2
ml/dl/hr, caused from Rh incompatiblity, also known as isoimmunization
pathologic jaundice is seen in ✅Rh - mother & Rh + infant, the mother is forming
antibodies against babys blood, has an effect on future pregnancies
pathologic jaundice testing ✅indirect coombs test, direct coombs test
Rh incompatibility ✅Rh- mom & Rh + baby, administer Rhogam
Rh incompatibility affects on infant ✅first time there is no harm to infant, after giving
birth mother is exposed to Rh+ & starts to make antibodies against it, if women gets
pregnent with another Rh+ baby her body will fight it
Rh incompatibility mother ✅Rh-
Rh incompatibility infant ✅Rh+
ABO incompatibility ✅fetal blood type is A,B, or AB, maternal blood type is O, not as
severe as Rh incompatibility
ABO incompatibility infant implications ✅naturally occuring anti A & B antibodies are
transferred across the placenta to the fetus, affects present pregnancy
What blood incompatibility is more severe? ✅Rh Incompatibility
, ABO incompatibility treatment ✅phototherapy
Rh Incompatibility treatment ✅RhoGAM
Indirect Coombs test ✅tests for Rh antibodies in maternal blood, performed at first
prenatal vist & repeated at 28 weeks gestation
Indirect Coombs test prescene of antibodies ✅1:8 sensitization to Rh, monitor fetus for
development of complications
Indirect Coombs test negative result ✅give RhoGAM at 28 weeks gestation
RhoGAM MOA ✅interrupts the development of Rh+ antibodies (normal sensitization)
process in women
Direct Coombs test ✅infant blood test, tests for maternal Rh+ antibodies in fetal cord
blood, shows whether maternal antibodies moved through the placenta to the infant
Direct Coombs Positive result ✅infants blood has maternal antibodies, maternal
antibodies will attack & destroy infants blood cells, greater risk for RBC breakdown
leading to increased risk of increased bilirubin
prevention of hyperbilirubinemia ✅watch for early signs, prevent the build up of
unconjugated bilirubin, make sure breastfeeding is effective, phototherapy
identification of hyperbilirubinemia progression ✅begins on the face, progresses to the
body, then to the extremities Cephalocaudal progression)
identification of hyperbilirubinemia initial locations ✅sclera, forehead, bridge of nose
identification of hyperbilirubinemia to assess ✅blanch skin over bony prominences
identification of hyperbilirubinemia in dark skined infants ✅assess sclera & mucous
membranes
transcutaneous bilirubin (TcB) measurements ✅greater than 12-15 mg/dL, used to
assess serum bilirubin, looks like a scan thermometer
American Academy of Pediatrics recommends ✅24 hour bilirubin level
identification of hyperbilirubinemia ✅cephalocaudal progression, assess,
transcutaneous bilirubin (TcB) measurments, American Academy of Pediatrics
