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:
Wearing a supportive bra can actually help to manage engorgement, so it's not recommended to avoid wearing one during the day.
Choice B rationale:
Cold compresses are typically applied after feeding to reduce swelling, not before. Applying them before might hinder the milk let-down reflex.
Choice C rationale:
Frequent feeding can help to alleviate engorgement by ensuring that the breasts are being emptied regularly.
Choice D rationale:
Stopping breastfeeding until finishing antibiotics is not advisable, as it can lead to decreased milk supply and potential issues with engorgement. Antibiotics prescribed by a healthcare provider are usually safe to take while breastfeeding, and interrupting breastfeeding can exacerbate the engorgement problem. This choice is not appropriate for managing breast engorgement and is therefore incorrect.
Correct Answer is B
Explanation
Choice A rationale:
Iron will facilitate bone growth. This statement is not accurate in the context of feeding a newborn with iron-fortified formula. While iron is essential for overall growth and development, its primary role is not specifically related to bone growth. Instead, it plays a crucial role in the production of hemoglobin, which helps carry oxygen in the blood.
Choice B rationale:
Newborns do not metabolize iron adequately. This statement is the correct choice. Newborns have limited iron stores that are obtained from their mothers during pregnancy. As they grow, their iron requirements increase, but their ability to metabolize iron is not fully developed at
birth. Hence, iron-fortified formula is recommended to provide the necessary iron for the newborn's healthy development.
Choice C rationale:
The newborn's iron source will start to deplete. This statement is not accurate in the context of iron-fortified formula feeding. The newborn's initial iron source is the iron stores passed on by the mother during pregnancy. However, the iron-fortified formula is designed to supplement and fulfill the baby's iron needs, preventing depletion of iron stores.
Choice D rationale:
Iron will facilitate eyesight development. This statement is not entirely accurate. While iron is important for many bodily functions, including eye health, it is not specifically responsible for eyesight development in newborns. Visual development in newborns is influenced by various factors, but iron intake through formula feeding directly impacting eyesight is not a primary concern.
