A nurse is reviewing the laboratory results of a newborn that is 4 hr old. Which of the following findings should the nurse identify as the priority?
Bilirubin 18 mg/dL.
Hemoglobin 22 g/dL.
Blood glucose 50 mg/dL.
Platelets 200,000/mm³.
The Correct Answer is A
Choice A rationale:
This is the priority finding because a bilirubin level of 18 mg/dL in a 4-hour-old newborn is significantly elevated. High bilirubin levels in newborns can lead to jaundice, which can be harmful if not promptly addressed. Hyperbilirubinemia in newborns requires close monitoring and, in some cases, treatment with phototherapy.
Choice B rationale:
A hemoglobin level of 22 g/dL is within the normal range for a newborn and is not a priority concern at this time.
Choice C rationale:
A blood glucose level of 50 mg/dL is within the normal range for a newborn. While monitoring blood glucose levels is essential, it is not the priority in this situation.
Choice D rationale:
A platelet count of 200,000/mm³ is within the normal range for a newborn and does not require immediate action.

Correct Answer is C
Explanation
Choice A rationale:
Reporting the client's weight to the provider is not a priority in this situation. While weight is important, the immediate concern is the newborn's respiratory distress and the acidosis indicated by the blood gases.
Choice B rationale:
Selecting diagnostic studies for the primary health care is not the nurse's role. The primary health care provider will determine which diagnostic studies are needed based on the newborn's clinical presentation and assessment findings.
Choice C rationale:
Checking brachial pulses for the client's respiratory status is the appropriate action. In a newborn with respiratory distress, assessing peripheral perfusion, including brachial pulses, is crucial to monitor the circulation and oxygenation of tissues.
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.
