The mother of a 4-hour-old newborn reports to a nurse, “My son is producing breast milk.” The nurse’s response should be based on which understanding about newborn physiology? This is:.

A symptom of an endocrine disorder.

In response to the need for chromosomal determination of gender identity.

Related to the influence of maternal hormones.

A symptom of an abnormal proliferation of mammary alveoli.

Answer and Explanation

The Correct Answer is C

The correct answer is choice C: Related to the influence of maternal hormones.This is because breast milk contains many hormones that pass into it from the mother’s body, such as prolactin, thyroid hormones, and estrogen.

These hormones can affect the baby’s growth and development, and sometimes cause temporary breast enlargement and milk secretion in newborns of both sexes. This is called neonatal galactorrhea or “witch’s milk” and it is harmless and usually resolves within a few weeks

Choice A is wrong because neonatal galactorrhea is not a symptom of an endocrine disorder. It is a normal physiological response to maternal hormones that cross the placenta during pregnancy and are present in breast milk

Choice B is wrong because neonatal galactorrhea is not related to the need for chromosomal determination of gender identity. Gender identity is determined by a complex interaction of genetic, hormonal, and environmental factors, and it is not influenced by breast milk production in newborns

Choice D is wrong because neonatal galactorrhea is not a symptom of an abnormal proliferation of mammary alveoli.

Mammary alveoli are the milk-producing cells in the breast, and they are stimulated by prolactin to secrete milk. Neonatal galactorrhea does not indicate any abnormality in the structure or function of the mammary glands

Correct Answer is A

Explanation

The correct answer is choice A. The newborn’s nostrils flare slightly during respiration.This is a sign of respiratory distress in a newborn.

Flaring nostrils indicate that the newborn is working hard to breathe and may not be getting enough oxygen.

Choice B is wrong because the newborn’s hands and feet are blue and feel cool.This is a normal finding called acrocyanosis, which occurs due to immature peripheral circulation.

It usually resolves within 24 to 48 hours after birth.

Choice C is wrong because the newborn’s eyes move randomly when his head is turned to the side.This is a normal finding called nystagmus, which occurs due to immature eye muscles and coordination.

It usually disappears by 6 months of age.

Choice D is wrong because the newborn’s tongue thrusts forward when it is lightly touched.This is a normal finding called the extrusion reflex, which helps the newborn to suck and swallow.

It usually fades by 4 months of age.

A. Making a loud sound within close range of the newborn. B. Firmly stroking the soles of the newborn’s feet with a thumb nail. C. Using the newborn’s hands to raise the baby from a supine position without supporting the head. D. Holding the newborn in an upright position so that the infant’s feet touch a cool, flat surface.
