What action by the nurse is the most important action in preventing neonatal infection?

A. Dressing the infant in only a T-shirt and diaper is not recommended during phototherapy because it reduces the amount of skin exposed to the light, which is necessary for effective treatment. The infant should be minimally clothed to maximize light exposure.

B. Restricting parental and oral fluids is incorrect. Adequate hydration is crucial during phototherapy to prevent dehydration, as the treatment can increase fluid loss through the skin.

C. Keeping the infant supine at all times is not necessary. The infant should be repositioned frequently to ensure all areas of the skin are exposed to the phototherapy light, which helps in reducing bilirubin levels more effectively.

D. Keeping the infant's eyes covered under the light is essential to protect the eyes from potential damage caused by the intense phototherapy light. This is a standard practice to prevent retinal damage and other eye complications.

Choice A: This is incorrect because Standard Precautions are a set of guidelines that apply to all patients, regardless of their infection status. They include using personal protective equipment, handling sharps and waste properly, and cleaning and disinfecting equipment and surfaces. However, they are not enough to prevent neonatal infection, as some pathogens can still be transmitted by contact or droplet.

Choice B: This is the correct answer because good hand hygiene is the most effective way to prevent the transmission of microorganisms that can cause neonatal infection. The nurse should wash their hands with soap and water or use an alcohol-based hand rub before and after touching the infant, the infant's environment, or any items that come in contact with the infant. The nurse should also educate the parents and visitors on the importance of hand hygiene and how to perform it correctly.

Choice C: This is incorrect because a separate gown technique involves wearing a clean gown for each infant and discarding it after use. This can help prevent cross-contamination between infants, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after wearing a gown, as well as before and after touching the infant or any items that come in contact with the infant.

Choice D: This is incorrect because isolation of infected infants involves placing them in a separate room or area with restricted access and using additional precautions based on the mode of transmission of the infection. This can help prevent the spread of infection to other infants, staff, or visitors, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after entering and leaving the isolation area, as well as before and after touching the infant or any items that come in contact with the infant.
