1. Which hormone is primarily responsible for the synthesis of
breastmilk?
A) Oxytocin
B) Estrogen
C) Prolactin
D) Progesterone
Answer: C
Rationale: Prolactin, released from the anterior pituitary, stimulates
alveolar cells to produce milk. Oxytocin causes ejection;
estrogen/progesterone inhibit lactation during pregnancy.
1
,2. Prolactin levels are highest in a breastfeeding mother at
which time?
A) Immediately before a feeding
B) During the first minute of feeding
C) 30–45 minutes after the start of feeding
D) 6 hours after the last feeding
Answer: C
Rationale: Prolactin peaks during and shortly after feeding,
especially at night. This supports ongoing milk production for
subsequent feeds.
3. The let-down reflex is triggered by which hormone?
A) Prolactin
B) Oxytocin
2
,C) Cortisol
D) hCG
Answer: B
Rationale: Oxytocin causes myoepithelial cells around alveoli to
contract, ejecting milk into ducts. Stress or pain can inhibit oxytocin
release.
4. Which maternal structure stores milk between feedings?
A) Alveoli
B) Lactiferous sinuses
C) Montgomery glands
D) Areolar glands
Answer: B
Rationale: The lactiferous sinuses (just behind the areola) store
small amounts of milk. However, most milk is stored in the alveoli
and ducts.
3
, 5. When does lactogenesis II (secretory activation) typically
occur?
A) 12–16 weeks gestation
B) Immediately after delivery of the placenta
C) 30–72 hours postpartum
D) 7–10 days postpartum
Answer: C
Rationale: Lactogenesis II begins 30–72 hours after placental
delivery, triggered by progesterone drop. This is when milk volume
increases ("milk coming in").
6. Which of the following indicates that lactogenesis II has
NOT occurred appropriately?
A) Colostrum production day 1
B) Breasts feeling fuller by day 4
