An 18-hour-old infant with hyperbilirubinemia is placed under phototherapy bank lights. Which of the following is an appropriate intervention for this infant?

Choice A rationale Keeping eye shields on at all times, including when breastfeeding, is crucial to protect the infant's retina from the high-intensity light emitted during phototherapy. Bilirubin in the retina can cause damage when exposed to light, and prolonged exposure can lead to permanent visual impairment. However, eye shields can be briefly removed during feeding to allow for bonding. Choice B rationale Keeping skin moisturized with lotion is generally not recommended during phototherapy. Lotions and oils can absorb the light, potentially causing skin burns or interfering with the efficacy of the phototherapy by blocking the penetration of light to the bilirubin in the skin. The skin should be clean and dry. Choice C rationale Exposing as much of the infant's skin to the lights as possible is the primary goal of phototherapy. Bilirubin is broken down into water-soluble isomers when exposed to specific wavelengths of light, primarily through the skin. Maximizing skin exposure increases the surface area available for bilirubin photoisomerization, enhancing the treatment's effectiveness. Choice D rationale Tightly swaddling the infant in a blanket is contraindicated during phototherapy. Swaddling covers the infant's skin, reducing the surface area exposed to the phototherapy lights and thus diminishing the treatment's effectiveness. Infants should be unclothed except for a diaper to maximize skin exposure.
