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
A. A blood glucose fingerstick of 40 mg/dL for an infant who is 1-hr old: A blood glucose level of 40 mg/dL is borderline low but expected in the immediate postnatal period, especially if the infant is asymptomatic. Feeding the infant is the first step to address this, and monitoring is usually sufficient unless symptoms of hypoglycemia develop.
B. A hematocrit of 60% in an infant who is 8-hr old: This value is at the upper end of normal for a newborn and may suggest mild polycythemia. However, it does not require urgent notification unless accompanied by symptoms such as respiratory distress or poor perfusion
C. Jaundice in an infant who is 4-hr old: Early-onset jaundice (within the first 24 hours) is not normal and suggests a potentially dangerous underlying condition, such as hemolytic disease of the newborn or infection. Immediate reporting and further evaluation, including bilirubin levels and possible treatment with phototherapy, are essential.
D. Acrocyanosis in an infant who is 2-hr old: Acrocyanosis (bluish discoloration of the hands and feet) is a common and benign finding in the first 24 to 48 hours after birth due to immature circulation. It does not require notification or intervention.
Correct Answer is B
Explanation
Choice A rationale:
The nurse should not report the client's Hemoglobin level first to the primary health care because it falls within the normal range of 14 to 24 g/dL for a newborn. Therefore, it is not an immediate concern.
Choice B rationale:
The nurse should first report the client's Chest x-ray results to the primary health care. The diffuse pattern of radiopaque areas bilaterally on the chest x-ray suggests possible respiratory distress or other respiratory issues in the newborn. This finding requires immediate attention and intervention to ensure proper respiratory function.
Choice C rationale:
The nurse should not report the client's Glucose level first to the primary health care as 40 mg/dL is within the normal range of 30 to 60 mg/dL for a newborn. Though it is on the lower side, it is not critically low, and there are more urgent concerns to address.
