C. Progesterone
D. Estrogen
Correct Answer: A
Rationale: Prolactin is the primary hormone responsible for milk secretion (lactogenesis). While
the drop in progesterone triggers the onset of copious milk production, it is prolactin that
stimulates the alveolar cells to produce milk. Oxytocin is responsible for milk ejection (the let-
down reflex), not secretion.
Question 2
What is the role of oxytocin in breastfeeding?
A. Milk synthesis
B. Milk ejection (let-down reflex)
C. Inhibiting milk production
D. Development of glandular tissue
Correct Answer: B
Rationale: Oxytocin is responsible for the milk ejection reflex, or "let-down." It causes the
myoepithelial cells surrounding the alveoli to contract, squeezing milk out of the alveoli and into
the ducts. Prolactin is responsible for milk synthesis.
Question 3
During which stage of lactogenesis does the milk "come in," typically occurring 2-5 days
postpartum?

Complete 3 Versions Exam Each 100 Questions Graded A+ (300 QUESTIONS)
A. Lactogenesis I
B. Lactogenesis II
C. Lactogenesis III
D. Galactopoiesis
Correct Answer: B
Rationale: Lactogenesis II is the stage when copious milk secretion begins, triggered by the
sudden drop in progesterone following delivery of the placenta. This is when the mother
experiences her milk "coming in." Lactogenesis I occurs during pregnancy, and Lactogenesis III
(galactopoiesis) is the maintenance of established milk production.
Question 4
Which of the following best describes the anatomy of the lactating breast?
A. A single large sac that stores milk
B. A system of ducts that leads to 15-20 lobes, each containing alveoli
C. A solid gland without any ductal system
D. A system of 5-10 lobes with no alveoli
Correct Answer: B
Rationale: The lactating breast consists of 15-20 lobes, each containing smaller lobules made up
of clusters of alveoli (milk-secreting cells). These alveoli drain into a system of ducts that lead to
the nipple. Milk is not stored in a single large sac but is synthesized and moves through this ductal
system.

Question 5
What is the function of Montgomery's glands?
A. To produce milk
B. To secrete a lubricating, protective substance for the nipple and areola
C. To transport milk to the nipple
D. To inhibit milk production
Correct Answer: B
Rationale: Montgomery's glands are small, raised bumps on the areola that secrete an oily,
lubricating substance. This secretion helps to protect the nipple and areola from cracking and
infection, and it may also have an olfactory function for the newborn.
Question 6
A mother reports that her breasts feel full and heavy on day 3 postpartum. This is most likely due
to:
A. Mastitis
B. Engorgement
C. A blocked duct
D. Insufficient milk supply
Correct Answer: B
Rationale: Breast fullness and heaviness around day 3-5 postpartum is a classic sign of
physiologic engorgement. This occurs as a result of increased blood flow, lymphatic fluid, and the
onset of copious milk production (Lactogenesis II). It is a normal process, though it can be
uncomfortable.
