A nurse is assessing a newborn who was born at 42.5 weeks of gestation. Which of the following findings should the nurse expect?
Faint red marks on the plantar surface.
Copious vernix.
Dry, cracked skin.
Scant scalp hair.
The Correct Answer is C
Choice A rationale
Faint red marks on the plantar surface are more common in preterm infants and are not typically seen in post-term infants.
Choice B rationale
Copious vernix is usually seen in preterm infants. Post-term infants often have little to no vernix.
Choice C rationale
Dry, cracked skin is a common finding in post-term infants due to prolonged exposure to the amniotic fluid.
Choice D rationale
Scant scalp hair is more common in preterm infants. Post-term infants usually have more developed hair.

Correct Answer is A
Explanation
Choice A rationale
Given the neonate’s symptoms and critically low blood glucose level (30 mg/dL), the most urgent action is to address the hypoglycemia. Therefore, the nurse shouldadminister a bolus of intravenous glucose (Option A). This immediate intervention is crucial to stabilize the neonate and prevent further complications associated with hypoglycemia.
Choice B rationale
While monitoring blood glucose levels is important, waiting 30 minutes to reassess without immediate intervention could allow the hypoglycemia to worsen, potentially leading to severe complications such as seizures or brain damage. Immediate treatment is necessary to stabilize the neonate.
Choice C rationale
Although feeding can help increase blood glucose levels, the neonate’s current symptoms (jitteriness, poor feeding, weak cry, and irritability) suggest that they may not be able to effectively feed. Additionally, the blood glucose level is critically low and requires more rapid correction than feeding alone can provide.
Choice D rationale
While maintaining an appropriate body temperature is important, the neonate’s temperature (36.1°C) is not critically low. The primary concern here is the hypoglycemia, which needs to be addressed immediately. Placing the neonate under a radiant warmer does not directly address the low blood glucose level.
Correct Answer is ["D","F","G","H"]
Explanation
Choice A rationale
Flexion of arms is a normal finding in newborns and does not indicate respiratory distress.
Choice B rationale
Caput succedaneum is a common condition where the scalp swells due to pressure during delivery. It does not indicate respiratory distress.
Choice C rationale
A heart rate of 158 bpm is within the normal range for newborns and does not indicate respiratory distress.
Choice D rationale
A respiratory rate of 66/min is above the normal range (30-60 breaths per minute) and indicates respiratory distress.
Choice E rationale
Acrocyanosis is common in newborns and does not indicate respiratory distress.
Choice F rationale
Subcostal retractions indicate increased work of breathing and are a sign of respiratory distress.
Choice G rationale
Nasal flaring is a sign of respiratory distress as it indicates increased effort to breathe.
Choice H rationale
Grunting is a sign of respiratory distress as it indicates difficulty in maintaining lung expansion.
