For which reason would a nurse in the well-baby nursery report to the neonatologist that a newborn appears to be preterm?
The baby has a square window angle of 90 degrees.
The baby has leathery and cracked skin.
The baby has a popliteal angle of 90 degrees.
The baby has pronounced plantar creases.
The Correct Answer is A
Choice A is correct. The square window angle, formed by the intersection of the ear and the jawline, is an important physical assessment finding in neonates. In full-term babies, this angle is typically greater than 90 degrees, appearing more rounded. However, in preterm babies, the angle is often closer to 90 degrees, appearing more square due to underdeveloped facial features and subcutaneous tissue.
Choice B is incorrect. While leathery and cracked skin can be present in both term and preterm babies, it's not a specific indicator of prematurity alone. It can be caused by various factors like intrauterine growth restriction, dehydration, or underlying skin conditions.
Choice C is incorrect. The popliteal angle, formed by flexing the knee and measuring the angle between the thigh and lower leg, is not a reliable indicator of prematurity. It can vary even among term babies and is influenced by other factors like muscle tone and positioning.
Choice D is incorrect. Pronounced plantar creases, the lines on the soles of the feet, are also not specific to prematurity. While they may be deeper in some preterm babies, they can also be present in full-term infants and their depth can vary greatly between individuals.
