What treatment uses fluorescent light to address jaundice in newborns?

The appropriate treatment for addressing jaundice in newborns involves the use of fluorescent light, commonly referred to as phototherapy. Phototherapy works by utilizing specific wavelengths of light to help reduce elevated levels of bilirubin in the bloodstream, which is the underlying cause of jaundice.

In the context of the choices provided, phototherapy represents the mechanism through which the treatment occurs. While the term "bililights" may also relate to a specific device used in phototherapy, the broader and more established term for the treatment itself is phototherapy. Physiologic jaundice treatment, although it describes management of physiologic jaundice, does not specifically denote the use of fluorescent light or phototherapy methods directly. Laser therapy is not typically involved in treating jaundice in newborns, as it is used for other medical applications.

Therefore, the correct choice is phototherapy, as it explicitly describes the use of light to facilitate the breakdown of bilirubin, effectively treating jaundice in neonates.
