Final answer:
A pediatric nurse should alert a supervisor about a neonate with a blue tint to the soles of the feet as it might indicate a serious oxygenation problem, which is part of the Apgar score assessment. Option d is correct.
Step-by-step explanation:
When assessing a neonate, the pediatric nurse should alert the head nurse or physician about the assessment finding of a blue tint to the soles of the feet. This could indicate an issue with oxygenation and could be a sign of peripheral cyanosis, which warrants immediate medical attention.
On the other hand, crossed eyes (strabismus) are not uncommon in neonates and generally resolve without intervention. A tuft of hair on the sacrum can be a normal variation but may also be a marker for underlying spinal abnormalities like spina bifida, so it should be noted but doesn't necessarily require immediate attention.
Purposeless movement of the arms is typical due to the immature nervous system of neonates. Therefore, it does not usually indicate a problem.
The Apgar score, introduced by Dr. Virginia Apgar in 1952, is a crucial measure of a newborn's well-being right after birth and includes an assessment of skin color, heart rate, reflexes, muscle tone, and respiration.
