QUESTIONS AND ANSWERS 2026 VERSION
1. The primary hormone responsible for milk production is:
A. Oxytocin
B. Prolactin
C. Estrogen
D. Progesterone
Answer: B
Rationale: Prolactin stimulates the alveolar cells in the
mammary gland to produce milk.
2. Oxytocin’s main role in lactation is:
A. Milk synthesis
B. Milk ejection (let-down reflex)
C. Suppression of ovulation
D. Inhibition of prolactin
Answer: B
Rationale: Oxytocin causes myoepithelial cells to contract,
ejecting milk from the alveoli to the ducts.
3. Colostrum is:
A. Mature milk produced after 6 months
B. Thick, yellowish milk produced in the first days postpartum
C. Milk high in fat but low in antibodies
D. Only produced if formula supplementation is avoided
,2
Answer: B
Rationale: Colostrum is nutrient-rich and immune-protective,
produced in the first 2–5 days after birth.
4. The primary source of energy for a newborn is:
A. Proteins
B. Carbohydrates in breast milk (lactose)
C. Fats only
D. Minerals
Answer: B
Rationale: Lactose provides the main energy source and aids
calcium absorption.
5. Which component of breast milk provides passive immunity
to the infant?
A. Lactose
B. Immunoglobulin A (IgA)
C. Casein
D. Vitamin D
Answer: B
Rationale: Secretory IgA coats the infant’s gut, protecting

6. Milk supply is primarily regulated by:
A. Maternal diet
B. Infant demand and milk removal
C. Maternal hydration
,3
D. Vitamin supplementation
Answer: B
Rationale: Frequent milk removal via breastfeeding or pumping
stimulates prolactin and maintains supply.
7. Engorgement is best managed by:
A. Cold packs only
B. Frequent breastfeeding and gentle massage
C. Avoiding feeding for several hours
D. Exclusive formula supplementation
Answer: B
Rationale: Regular emptying and massage relieve fullness and
prevent mastitis.
8. A mother with mastitis is usually advised to:
A. Stop breastfeeding immediately
B. Continue breastfeeding and treat infection with antibiotics if
necessary
C. Switch to formula only
D. Use herbal remedies exclusively
Answer: B
Rationale: Continuing breastfeeding clears ducts, promotes
healing, and maintains supply.
9. Foremilk differs from hindmilk in that it:
A. Is higher in fat
B. Is lower in fat and higher in lactose
, 4
C. Is produced only at night
D. Contains antibodies only
Answer: B
Rationale: Foremilk is watery, satisfying thirst, while hindmilk is
richer in fat for satiety and growth.
10. The let-down reflex can be triggered by:
A. Infant crying
B. Skin-to-skin contact
C. Maternal relaxation
D. All of the above
Answer: D
Rationale: Psychological and physical stimuli promote oxytocin
release and milk ejection.
11. Breastfeeding reduces the risk of which maternal condition?
A. Breast cancer
B. Ovarian cancer
C. Type 2 diabetes
D. All of the above
Answer: D
Rationale: Breastfeeding has protective effects on multiple
maternal health outcomes.
12. An infant who is jaundiced and dehydrated may benefit
