The student nurse learns that the hormone necessary for milk production is
Estrogen.
Prolactin.
Progesterone.
Lactogen.
The Correct Answer is B
The correct answer is choice B. Prolactin.
Choice A reason:
Estrogen. Estrogen is a hormone that plays a role in the development of the mammary glands and the ductal system during pregnancy. However, estrogen does not directly produce milk.
In fact, high levels of estrogen during pregnancy inhibit milk secretion by blocking prolactin. Therefore, estrogen is not the hormone necessary for milk production. • Choice B reason:
Prolactin. Prolactin is the hormone responsible for the production of breast milk. Prolactin is secreted by the pituitary gland in response to suckling or nipple stimulation. Prolactin levels rise during pregnancy and peak after delivery, when the sudden drop in estrogen and progesterone allows prolactin to take over and initiate lactation. Therefore, prolactin is the hormone necessary for milk production. • Choice C reason:
Progesterone. Progesterone is a hormone that also contributes to the development of the mammary glands and the alveoli during pregnancy. However, like estrogen, progesterone does not directly produce milk. Progesterone also inhibits milk secretion by blocking prolactin during pregnancy. Therefore, progesterone is not the hormone necessary for milk production. •
Choice D reason:
Lactogen. Lactogen is not a hormone, but a general term for any substance that stimulates lactation. There are different types of lactogens, such as human placental lactogen (hPL), which is produced by the placenta during pregnancy and has some lactogenic effects on the mammary glands. However, hPL is not the main hormone responsible for milk production. That role belongs to prolactin. Therefore, lactogen is not the hormone necessary for milk production.

Correct Answer is D
Explanation
The correct answer is choice D. Announcement of the delivery.
Choice A reason:
Support thermoregulation is a priority in nursing care of the newborn immediately after birth. Newborns are at risk of hypothermia because they have a large surface area to body mass ratio, thin skin, and limited subcutaneous fat. To prevent heat loss, newborns should be dried thoroughly, placed skin-to-skin with the mother, and covered with warm blankets.
Choice B reason:
Identifying the infant is a priority nursing care of the newborn immediately after birth. Newborns should be identified with identification bands that match those of the mother and father or significant other. This helps prevent errors in infant identification and ensures safety and security.
Choice C reason:
Promoting normal respirations is a priority nursing care of the newborn immediately after birth. Newborns need to establish effective breathing patterns to ensure adequate oxygenation and prevent complications such as respiratory distress syndrome or meconium aspiration syndrome. To promote normal respirations, newborns should be suctioned gently to clear the airway, stimulated to cry, and assessed for signs of distress.
Choice D reason:
Announcement of the delivery is not a priority in nursing care of the newborn immediately after birth. While it may be a joyful moment for the parents and family, it does not affect the health and well-being of the newborn. Therefore, it can be done later after the essential newborn care has been completed.
