Which information would the nurse include when teaching a new mother about the difference between pathologic and physiologic jaundice?

Choice A rationale Kernicterus, which is brain damage caused by excessive unconjugated bilirubin deposits, is a severe complication primarily associated with pathologic jaundice, not physiologic jaundice. Physiologic jaundice is common and self-limiting because bilirubin levels usually peak below the critical thresholds needed to breach the blood-brain barrier. Choice B rationale Pathologic jaundice is defined by its early onset, appearing within the first 24 hours after birth, which is a key distinguishing feature. This rapid rise in bilirubin often indicates an underlying condition, such as hemolytic disease of the newborn, that requires urgent investigation and treatment to prevent complications. Choice C rationale Exchange transfusion is a severe intervention, occasionally used to treat critically high bilirubin levels associated with pathologic jaundice, especially in cases of Rh or ABO incompatibility. Physiologic jaundice is typically treated with non-invasive phototherapy and never requires such an aggressive procedure. Choice D rationale Physiologic jaundice is a benign, transient condition that affects most newborns and does not require transfer to the Neonatal Intensive Care Unit (NICU). Treatment, if needed, is usually simple phototherapy, which can often be managed on a regular maternity unit or even at home.
