recommended
what are characteristics of Rh factor incompatibility?
• Rh- mom with Rh+ fetus
• Fetal Rh+ RBCs leak into maternal blood & trigger
maternal Rh antibody formation
• Maternal antibodies cross back into fetal blood & attack fetal RBCs, usually in subsequent pregnancy
what are the two types of hyperbilirubinemia?
physiologic and pathologic
what are the 3 characteristics of physiologic hyperbilirubinemia?
– Appears after 24 hrs
– Result of increased RBCs & immature liver (born w/ ↑ H + H)
