Q1: A first-time mother asks when her body starts making milk for her baby. The
lactation counselor explains that secretory differentiation (Lactogenesis Stage I)
typically begins when?
A. Immediately after the baby's first feeding
B. Around mid-pregnancy [CORRECT]
C. Within 24 hours after birth
D. When the baby begins cluster feeding
,Correct Answer: B
Rationale: Lactogenesis Stage I (secretory differentiation) begins around mid-pregnancy
(16-20 weeks gestation), when the breasts start producing colostrum. This happens
before birth, not after. Stage II occurs postpartum (days 2-3), and cluster feeding (D)
relates to established breastfeeding, not milk production onset.
Q2: A nursing student asks about the hormone responsible for milk ejection during
breastfeeding. Which explanation by the counselor is most accurate?
A. "Prolactin causes the milk to flow when the baby suckles."
B. "Oxytocin triggers the let-down reflex, causing milk ejection." [CORRECT]
C. "Progesterone maintains milk production throughout lactation."
D. "Estrogen stimulates the alveoli to contract and release milk."
Correct Answer: B
Rationale: Oxytocin causes myoepithelial cells to contract, producing the milk ejection
reflex (let-down). Prolactin (A) drives milk synthesis, not ejection. Progesterone (C) and
estrogen (D) actually suppress lactation during pregnancy and drop after delivery to
allow lactation to proceed.
,Q3: A mother on day 2 postpartum notices her breasts feeling fuller and warmer, with
milk appearing more copious and whiter. The counselor recognizes this as the transition
to which stage of lactogenesis?
A. Stage I: secretory differentiation
B. Stage II: secretory activation [CORRECT]
C. Stage III: galactopoiesis
D. Stage IV: lactation weaning
Correct Answer: B
Rationale: Stage II (secretory activation) occurs days 2-8 postpartum, marked by
copious milk secretion, breast fullness, and milk changing from colostrum to
transitional milk. Stage I (A) is prenatal colostrum production, Stage III (C) is established
milk production maintenance, and Stage IV (D) is not a standard lactogenesis stage.
Q4: Which component of breast milk provides the primary source of energy and calories
for the growing infant?
A. Lactose
B. Whey protein
, C. Fat [CORRECT]
D. Immunoglobulin A
Correct Answer: C
Rationale: Fat provides approximately 50% of the calories in breast milk and is essential
for infant growth, brain development, and fat-soluble vitamin absorption. While lactose
(A) is the primary carbohydrate and whey (B) is important protein, fat is the most
calorie-dense component. IgA (D) provides immune protection, not energy.
Q5: A mother expresses concern about the yellowish color of her milk on day 3. The
counselor explains this is:
A. A sign of infection requiring antibiotics
B. Normal colostrum transitioning to transitional milk [CORRECT]
C. Evidence of insufficient fat content
D. Caused by dietary beta-carotene only
Correct Answer: B
