What should the parents of infants with a positive phenylketonuria (PKU) test be instructed to do?
Give the infant a high protein diet.
Provide the infant with a diet containing small amounts of phenylalanine.
Early introduction of cow’s milk may be necessary before 1 year of age.
Follow up with a pediatric cardiologist.
The Correct Answer is B
Choice A rationale
Giving an infant with a positive PKU test a high protein diet is not recommended. This is because phenylalanine, which cannot be broken down by individuals with PKU, is found in high-protein foods.
Choice B rationale
Parents of infants with a positive PKU test should provide the infant with a diet containing small amounts of phenylalanine. This is because while phenylalanine is harmful in large amounts to individuals with PKU, it is still an essential amino acid that the body needs in small amounts.
Choice C rationale
Early introduction of cow’s milk is not necessary before 1 year of age for infants with a positive PKU test. In fact, cow’s milk is high in phenylalanine and should be avoided.
Choice D rationale
Following up with a pediatric cardiologist is not specifically related to the dietary management of PKU. While regular medical supervision is important for children with PKU, it does not necessarily have to be with a cardiologist.

Correct Answer is A
Explanation
Choice A rationale
Phototherapy is commonly used to treat neonatal jaundice. One of the typical outcomes of phototherapy is frequent loose stool. This happens because the therapy helps to eliminate bilirubin, the substance that causes jaundice, from the baby’s body through stool. Choice B rationale
A purpuric rash is not a typical outcome of phototherapy. It could be a sign of a different medical condition and should be evaluated by a healthcare provider.
Choice C rationale
Clear, transparent urine is not specifically associated with phototherapy. Urine color can be influenced by many factors, including hydration status and certain medical conditions. Choice D rationale
Lethargy is not a typical outcome of phototherapy. If a baby appears lethargic, it could be a sign of a serious condition that needs immediate medical attention.
