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 B
Explanation
Choice A rationale:
This response would not be appropriate because it provides incorrect information. Breast milk is already present in the mother's breasts during pregnancy, and the newborn's disinterest in eating is likely due to other factors.
Choice B rationale:
This is the best response because it acknowledges the mother's concern and offers a practical solution to help the newborn latch onto the breast properly. Correct latching is crucial for successful breastfeeding, and once the baby latches on correctly, they are more likely to breastfeed effectively.
Choice C rationale:
While it is true that newborns often experience deep sleep phases, attributing the disinterest in eating solely to deep sleep is not accurate. Offering support and guidance for breastfeeding would be more beneficial.
Choice D rationale:
This response oversimplifies the situation and may not address the actual reason for the newborn's disinterest in feeding. It is essential to help the mother with proper techniques rather than just waking up the baby.
Correct Answer is A
Explanation
Choice A rationale:
Placing the newborn in an incubator is essential because the newborn's temperature control mechanism is immature. Premature infants have an underdeveloped thermoregulatory system, making them susceptible to heat loss and cold stress. An incubator provides a controlled, warm environment to maintain the newborn's body temperature within the normal range (around 36.5°C to 37.5°C or 97.7°F to 99.5°F).
Choice B rationale:
Heat increasing the flow of oxygen to the newborn's extremities is not a valid reason for placing the newborn in an incubator. Oxygenation is primarily influenced by respiratory and circulatory mechanisms, not external heat.
Choice C rationale:
The newborn's small body surface area for his weight is not directly related to the need for an incubator. Premature infants have a higher surface area to weight ratio, making them more prone to heat loss, but this is not the primary reason for using an incubator.
Choice D rationale:
Heat facilitating the drainage of mucus is not a reason for placing the newborn in an incubator. Proper positioning and suctioning are used to manage mucus in premature infants, but incubators are primarily for temperature regulation.
