A nurse is assessing a newborn and evaluating for developmental dysplasia of the hip (DDH). What assessment finding would indicate DDH?
Inwardly turned foot on the affected side.
Gluteal folds are asymmetrical.
Absence of Babinski sign.
Absence of stepping reflex.
The Correct Answer is B
Choice A rationale
An inwardly turned foot is not a sign of DDH. It may indicate a different condition such as clubfoot.
Choice B rationale
Asymmetrical gluteal folds are a common sign of developmental dysplasia of the hip (DDH). This occurs because the hip joint is not properly aligned, causing uneven skin folds.
Choice C rationale
The absence of the Babinski sign is not related to DDH. The Babinski sign is a reflex test used to assess neurological function.
Choice D rationale
The absence of the stepping reflex is not related to DDH. The stepping reflex is a normal newborn reflex that disappears after a few months.

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.
Correct Answer is D
Explanation
Choice A rationale
An apical pulse rate of 124 bpm is within the normal range for a neonate (110-160 bpm). There is no need to ask another nurse to verify the heart rate as it is not an abnormal finding.
Choice B rationale
Calling the provider for an apical pulse rate of 124 bpm is unnecessary as it is within the normal range for a neonate. This action would be appropriate if the heart rate were significantly outside the normal range.
Choice C rationale
Preparing the newborn for transport to the NICU for an apical pulse rate of 124 bpm is not warranted. The heart rate is within the normal range, and there is no indication for further cardiac observation.
Choice D rationale
Documenting the expected finding is the appropriate action. An apical pulse rate of 124 bpm is within the normal range for a neonate, and no further action is needed.
