Which statement about phototherapy is incorrect?

A) Light from the blue to white spectrum is used
B) It is not always necessary to use a shield for the infant's eyes
C) Unconjugated bilirubin in the skin is converted to a water-soluble nontoxic substance that is excreted in the bile
D) The infant's eyes should be shielded

The correct answer is: B) It is not always necessary to use a shield for the infant's eyes

The statement that it is not always necessary to use a shield for the infant's eyes is incorrect because protecting an infant's eyes during phototherapy is crucial. The use of blue light for phototherapy is effective for treating conditions like hyperbilirubinemia, primarily in neonates. However, exposure to bright light can potentially damage the infant's retinas, which makes it important to shield the eyes adequately. While certain situations may not require a shield if the duration and intensity of light exposure are minimal, the general guideline emphasizes the necessity of eye protection to ensure safety and prevent ocular damage. Therefore, the practice of shielding the eyes during phototherapy is a standard protocol to protect the delicate tissues of the infant's eyes from potential harm while undergoing treatment. This underscores the importance of adherence to guidelines to ensure the well-being of neonates receiving phototherapy.
