Which newborn is at the lowest risk for elevated unconjugated bilirubin levels?
The newborn with significant bruising from a face presentation.
The premature newborn.
The baby born at 41 weeks' gestation.
The newborn with O+ blood type, born to a mother with O- blood type.
The Correct Answer is C
Choice A rationale:
(Incorrect) The newborn with significant bruising from a face presentation is at an increased risk of elevated unconjugated bilirubin levels. Bruising can lead to the breakdown of red blood cells, increasing bilirubin production.
Choice B rationale:
(Incorrect) The premature newborn is at a higher risk of elevated unconjugated bilirubin levels. Premature infants often have an underdeveloped liver, which can lead to reduced bilirubin processing and clearance.
Choice C rationale:
(Correct) The baby born at 41 weeks' gestation is at the lowest risk for elevated unconjugated bilirubin levels. By this stage, the baby's liver is more mature, allowing for efficient processing and clearance of bilirubin.
Choice D rationale:
(Incorrect) The newborn with O+ blood type, born to a mother with O- blood type, is at an increased risk of elevated unconjugated bilirubin levels if the baby's blood type is Rh-positive and the mother's is Rh-negative. This situation can lead to Rh incompatibility and hemolytic disease of the newborn, causing higher bilirubin levels.

Correct Answer is A
Explanation
"My baby will be placed under special lights if the test is elevated.”.
Choice A rationale:
This statement indicates a need for further teaching. Phenylketonuria (PKU) is a metabolic disorder that leads to the accumulation of phenylalanine in the body. If the PKU test is elevated, it means that the baby has high levels of phenylalanine, and immediate dietary intervention is required. The parent's statement about special lights suggests a confusion with jaundice treatment, which is not related to PKU.
Choice B rationale:
This statement is accurate. Before the PKU test is done, the baby needs to consume formula or breast milk to ensure accurate test results.
Choice C rationale:
This statement is also accurate. PKU is a genetic disorder that can be managed with a special diet low in phenylalanine. By adhering to the prescribed diet, the harmful effects of PKU can be minimized.
Choice D rationale:
This statement is accurate. It is common for the PKU test to be repeated at the 2-week check- up to confirm the initial results and ensure early detection and management of PKU if present.
Correct Answer is A
Explanation
Choice A rationale:
30 ml is equal to approximately half an ounce. One ounce is equivalent to 29.57 ml. This conversion is essential in pediatric care, especially when administering medications to infants, as doses are often prescribed in milliliters.
Choice B rationale:
Three ounces is not the correct conversion for 30 ml. Three ounces would be equivalent to approximately 88.71 ml, which is significantly more than 30 ml.
Choice C rationale:
Two ounces is not the correct conversion for 30 ml. Two ounces would be approximately
59.15 ml, which is still more than 30 ml. Choice D rationale:
One ounce is not the correct conversion for 30 ml. As mentioned earlier, one ounce is approximately 29.57 ml, which is slightly less than 30 ml. The correct conversion is half an ounce (approximately 14.79 ml more than 29.57 ml), as stated in Choice A.
