A newborn is being assessed for risk of hyperbilirubinemia. The infant has both caput succedaneum and a cephalohematoma. The nurse understands that phototherapy is more likely to be required in which condition, and why?

Caput succedaneum can lead to severe bruising and therefore often requires phototherapy.

Neither condition increases bilirubin levels so phototherapy is not needed for either.

Phototherapy is more likely needed with caput succedaneum because it increases blood cell breakdown under the scalp.

Cephalohematoma increases the risk of hyperbilirubinemia due to the breakdown of trapped red blood cells, which may require phototherapy.
