Which statement regarding phototherapy is incorrect?

Phototherapy is a common treatment for neonatal jaundice, and its effectiveness is closely tied to the safety measures in place for the infant. In assessing the statements, the crucial detail about why the statement regarding the necessity of shielding the infant's eyes is identified as incorrect lies in the established protocols for this treatment.

During phototherapy, it is essential to protect the infant’s eyes because the blue light used can potentially cause retinal damage if not shielded. Shielding the eyes prevents exposure to the harmful wavelengths that could affect the developing vision. Therefore, the assertion that a shield is not always necessary contradicts best practices and standard care protocols.

In contrast, the other statements accurately reflect key aspects of phototherapy. The use of light in the blue to white spectrum is correct, as these wavelengths are most effective in reducing levels of unconjugated bilirubin. The process by which unconjugated bilirubin in the skin is converted to a water-soluble substance that can be excreted in the bile is also a true depiction of how phototherapy functions. Thus, the focus on eye protection is a critical component of safe practicing standards in phototherapy for infants, reinforcing the importance of the correct answer regarding the necessity of shielding the infant's eyes.
