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 C
Explanation
Choice A rationale
Depressed fontanelles are not exclusive to premature newborns. They can occur in both premature and full-term infants and are not an indicator of prematurity.
Choice B rationale
Depressed fontanelles do not indicate infection. Infections in newborns typically present with other symptoms such as fever, irritability, and poor feeding.
Choice C rationale
Depressed fontanelles are a sign of dehydration in newborns. When a newborn is dehydrated, the fontanelles can appear sunken due to the lack of fluid in the body.
Choice D rationale
Depressed fontanelles are not a normal finding in newborns. Normally, fontanelles should be flat or slightly curved inward. A depressed fontanelle is a clinical sign that requires further evaluation and intervention.
Correct Answer is A
Explanation
Choice A rationale
Placing a baby on their back to sleep significantly reduces the risk of SIDS. This position helps keep the airway open and reduces the risk of suffocation.
Choice B rationale
There is no direct correlation between SIDS and the diphtheria, tetanus, and pertussis vaccines. Vaccines are safe and do not increase the risk of SIDS3.
Choice C rationale
SIDS rates have actually decreased over the last 10 years, largely due to public health campaigns promoting safe sleep practices.
Choice D rationale
Sleep apnea is not the main cause of SIDS. The exact cause of SIDS is unknown, but it is believed to be related to defects in the brain that control breathing and arousal from sleep.
