Phototherapy is an essential treatment for jaundice in newborns, particularly those with high levels of bilirubin. This therapy involves exposing the infant to specific wavelengths of light, which aids in the transformation of bilirubin into a more water-soluble form. By breaking down bilirubin in the skin, phototherapy facilitates its excretion through the liver and kidneys, effectively reducing the bilirubin levels in the bloodstream. This process is crucial because elevated bilirubin can lead to serious complications if not managed promptly.

The other options do not accurately describe the primary function of phototherapy. While maintaining hydration is important for infants, phototherapy does not specifically hydrate the skin. Similarly, vitamin D absorption is not directly promoted by phototherapy, and it does not increase oxygen levels in infants. By focusing on the breakdown of bilirubin, phototherapy plays a vital role in treating jaundice and preventing potential neurological damage caused by excessive bilirubin levels.
