The nurse is caring for a newborn one hour after delivery. Which of the following assessment findings does the nurse identify as signs of respiratory distress? (Select all that apply)
Flexion of arms.
Caput succedaneum.
Heart rate 158 bpm.
Respiratory rate 66/min.
Acrocyanosis.
Subcostal retractions.
Nasal flaring.
Grunting.
Correct Answer : D,F,G,H
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.

Correct Answer is B
Explanation
Choice A rationale
Small for gestational age (SGA) refers to newborns whose birth weight is below the 10th percentile for their gestational age.
Choice B rationale
Appropriate for gestational age (AGA) refers to newborns whose birth weight is between the 10th and 90th percentiles for their gestational age. A newborn weighing 3350 g at 39 weeks gestation falls within this range.
Choice C rationale
Low birth weight is defined as a birth weight of less than 2500 g, which does not apply to this newborn.
Choice D rationale
Large for gestational age (LGA) refers to newborns whose birth weight is above the 90th percentile for their gestational age.
Correct Answer is B
Explanation
Choice A rationale
Shivering is not a primary concern for newborns as they have limited ability to shiver. Instead, they rely on non-shivering thermogenesis to maintain body temperature.
Choice B rationale
Cold stress is a significant concern for newborns as it can lead to hypothermia, increased oxygen consumption, and metabolic acidosis. Placing a newborn under a radiant heat warmer helps maintain their body temperature and prevent cold stress.
Choice C rationale
Brown fat production is a natural process in newborns that helps generate heat. However, the primary purpose of using a radiant heat warmer is to prevent cold stress, not to stimulate brown fat production.
Choice D rationale
Basal metabolic rate reduction is not the primary concern. The focus is on preventing cold stress and maintaining the newborn’s body temperature.
