Question 1: During which stage of lactogenesis does the
dramatic increase in milk production, often referred to as milk
"coming in," occur?
A. Stage I lactogenesis
B. Stage II lactogenesis
C. Stage III lactogenesis
D. Stage IV lactogenesis
Correct Answer: B. Stage II lactogenesis
Rationale: Stage II lactogenesis begins about two to three days
postpartum when the drop in estrogen and progesterone allows
1
,prolactin to take over, leading to a dramatic increase in milk
production. This is when mothers notice their milk "coming in" with
breast fullness and often engorgement. Stage I occurs during
pregnancy, and Stage III is the maintenance phase where supply
is driven by demand .
Question 2: Prolactin is the primary hormone responsible for:
A. Ejection of milk from the alveoli
B. Production of milk by the alveoli
C. Inhibition of milk production
D. Contraction of the uterus
Correct Answer: B. Production of milk by the alveoli
Rationale: Prolactin is the hormone responsible for milk
production. It causes the alveoli in the mammary glands to
synthesize and secrete milk. Oxytocin, not prolactin, is
responsible for milk ejection (let-down). Prolactin levels rise
2
,during pregnancy but are suppressed by high estrogen and
progesterone until after delivery of the placenta .
Question 3: The let-down reflex is triggered by which hormone?
A. Prolactin
B. Estrogen
C. Progesterone
D. Oxytocin
Correct Answer: D. Oxytocin
Rationale: Oxytocin is responsible for the let-down reflex,
causing muscle contractions that eject milk from the alveoli
through the milk ducts. Suckling stimulates nerves that signal the
release of both prolactin and oxytocin. The let-down typically
occurs after about 30 seconds of suckling and can cause milk to
drip from both breasts .
Question 4: What is the primary function of colostrum?
A. To provide high volumes of milk for the newborn
3
, B. To supply immunoglobulins and concentrated nutrition
C. To induce lactation
D. To increase maternal hormone levels
Correct Answer: B. To supply immunoglobulins and
concentrated nutrition
Rationale: Colostrum is the first milk produced during pregnancy
and the early postpartum period. It is highly concentrated,
nutritious, and rich in immunoglobulins (especially IgA) that
provide passive immunity to the newborn. It is lower in volume
but higher in protein and antibodies than mature milk, making it
perfectly suited for the newborn's needs .
Question 5: The posterior dominant rhythm is characterized by
which of the following?
A. Eye movement artifact
B. Alpha rhythm
