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 A
Explanation
Choice A rationale
Drying the newborn’s skin thoroughly immediately after birth helps reduce heat loss by evaporation, which is a significant concern as wet skin can cause rapid heat loss.
Choice B rationale
Maintaining ambient room temperature at 24°C (75°F) helps prevent heat loss by convection but does not directly address evaporation.
Choice C rationale
Placing the newborn on a warm surface helps prevent heat loss by conduction but does not address evaporation.
Choice D rationale
Preventing air drafts helps reduce heat loss by convection but does not address evaporation.
Correct Answer is B
