A nurse is reinforcing teaching about phenylketonuria (PKU) testing with the parent of a newborn. Which of the following statements by the parent indicates a need for further teaching?
"My baby will be placed under special lights if the test is elevated.".
"My baby must take formula or breast milk before the test is done.".
"This test checks for a genetic disorder that can be corrected by diet.".
"Sometimes the test is repeated in the doctor's office at the 2-week check-up.".
The Correct Answer is A
"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 C
Explanation
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
Choice A rationale:
The correct guidance includes giving the newborn sponge baths until the cord stump falls off, which helps to keep the area dry. It is essential to keep the umbilical cord stump clean and dry to prevent infection. Submerging the cord stump in water could increase the risk of infection.
Choice B rationale:
Covering the cord with the diaper is not advisable. The diaper could trap moisture around the cord stump, leading to a higher risk of infection. The cord stump should be exposed to air as much as possible to aid in drying and healing.
Choice C rationale:
Washing the cord with mild soap and water is not necessary and could introduce moisture, which should be avoided. Instead, the stump should be cleaned gently with a soft, dry cloth if it gets dirty.
Choice D rationale:
Wrapping the cord in petroleum jelly gauze is not a recommended practice. Applying petroleum jelly or other substances to the cord stump can interfere with the drying process and increase the risk of bacterial growth, leading to infection.
