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 D
Explanation
Choice A rationale:
Notifying the provider immediately may be an appropriate action in certain urgent situations. However, for a newborn who has not voided for the first time yet, it is not an immediate emergency. The priority is to assess the newborn's condition further before notifying the provider.
Choice B rationale:
Pressing on the bladder to prevent urine retention is not a recommended action. Applying pressure on the newborn's bladder can be harmful and is not a standard nursing practice.
Choice C rationale:
Administering IV fluid is not the priority action for a newborn who has not voided. Newborns usually receive sufficient hydration from breastfeeding or formula feeding, and administering IV fluid without proper indication can lead to potential complications.
Choice D rationale:
Documenting and continuing monitoring is the correct priority action in this situation. Newborns often take some time to pass their first urine, and it is considered normal for them to have delayed voiding within the first 24 hours after birth. The nurse should document the absence of voiding and monitor the newborn for any signs of distress or abnormalities. If the newborn's condition worsens or if there are other concerning symptoms, then notifying the provider may be necessary.
Correct Answer is B
Explanation
Choice A rationale:
Providing a heat source for the newborn is not the purpose of surfactant. Surfactant is a substance produced in the lungs to reduce surface tension and prevent alveolar collapse during expiration. It helps with the exchange of gases, but it does not generate heat.
Choice B rationale:
This is the correct answer. Surfactant plays a crucial role in assisting the alveoli to remain open by reducing surface tension. This, in turn, allows for proper gas exchange, especially of oxygen and carbon dioxide.
Choice C rationale:
Assisting the ductus arteriosus to remain open is not the purpose of surfactant. The ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs. After birth, it should close on its own, and surfactant does not influence this process.
Choice D rationale:
Providing energy to the newborn is not the purpose of surfactant. Energy for the newborn comes from nutrition, particularly breast milk or formula, and not from surfactant
