Answer:
The passing of meconium after 24 hours, the initiation of newborn feedings delayed after birth, and twin-to-twin transfusion syndrome would result in enhanced levels of bilirubin in the newborn.
The delay in the newborn feedings and in the passage of meconium could result in the enhanced levels of bilirubin due to increased enterohepatic circulation. The twin-to-twin transfusion syndrome could result in enhanced levels of bilirubin as an outcome of an increased concentration of hemoglobin.
An enhancement in the levels of bilirubin would be observed if cord clamping was delayed after birth. Hypoglycemia could result in increased levels of bilirubin due to changes in hepatic function and perfusion.
