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 A
Explanation
Choice A rationale:
An apical pulse of 130/min in a newborn is within the normal range. The normal heart rate for a newborn is generally between 110 to 160 beats per minute (bpm). As the newborn's heart rate falls within this range, the nurse should document it as an expected finding and continue routine monitoring.
Choice B rationale:
Calling the neonatologist to assess the newborn for an apical pulse of 130/min is not warranted as it is a normal finding. The nurse should only notify the neonatologist if there are abnormal vital signs or concerning clinical signs.
Choice C rationale:
Asking another nurse to verify the heart rate is unnecessary in this scenario. The nurse can independently measure the apical pulse and document the finding as long as it falls within the normal range for newborns.
Choice D rationale:
Preparing the newborn for transport to the Neonatal Intensive Care Unit (NICU) is not indicated for a normal apical pulse rate. Transporting a newborn to the NICU is typically reserved for critical or unstable conditions. In this case, the normal heart rate of 130/min does not warrant NICU transport.
Correct Answer is C
Explanation
Choice A rationale:
Iron is crucial for the development of hemoglobin, which carries oxygen to all parts of the body, including the bones, but it does not directly facilitate bone growth.
Choice B rationale:
While newborns do metabolize iron, their iron stores are limited, and breast milk alone may not meet their iron needs.
Choice C rationale:
When educating a parent about the use of iron-fortified formula for their newborn, it is essential to convey that newborns have a limited store of iron, which begins to deplete around the age of 6 months.
Choice D rationale:
Iron facilitating eyesight development is not a relevant aspect to consider when discussing the use of iron-fortified formula for a newborn. While iron is essential for various physiological functions, it is not specifically linked to eyesight development.
