1. Which hormone is primarily responsible for milk production?
A. Oxytocin
B. Estrogen
C. Progesterone
D. Prolactin
Answer: D. Prolactin
Rationale: Prolactin, secreted by the anterior pituitary gland, stimulates
milk synthesis within the alveolar cells of the breast. Oxytocin is
responsible for milk ejection rather than production. Estrogen and
progesterone prepare the breasts for lactation during pregnancy but
inhibit large-scale milk secretion until after birth, when their levels
decline.
, 2. Which hormone is responsible for the milk ejection (let-down)
reflex?
A. Prolactin
B. Cortisol
C. Oxytocin
D. Progesterone
Answer: C. Oxytocin
Rationale: Oxytocin causes the myoepithelial cells surrounding the milk-
producing alveoli to contract, pushing milk through the ducts toward
the nipple. Prolactin produces milk but does not eject it. Cortisol
supports metabolism, while progesterone suppresses milk production
during pregnancy.
3. Colostrum is best described as:
A. Mature milk produced after six weeks
B. Formula substitute
C. The first milk produced after birth, rich in antibodies
D. Milk produced only after cesarean birth
Answer: C. The first milk produced after birth, rich in antibodies
,Rationale: Colostrum is produced during late pregnancy and the first
few days postpartum. It is highly concentrated with immunoglobulins,
especially IgA, white blood cells, and growth factors that protect the
newborn. It is not related to the mode of birth and is not a substitute for
formula.
4. Which immunoglobulin is most abundant in human breast milk?
A. IgG
B. IgM
C. IgE
D. Secretory IgA
Answer: D. Secretory IgA
Rationale: Secretory IgA provides passive immunity by coating the
infant's gastrointestinal tract and preventing pathogen attachment.
Although other antibodies are present, secretory IgA is the predominant
immune component in breast milk.
5. A healthy full-term newborn should ideally begin breastfeeding:
A. Within 24 hours
B. After bathing
, C. After receiving formula
D. Within the first hour after birth
Answer: D. Within the first hour after birth
Rationale: Early skin-to-skin contact and breastfeeding within the first
hour improve breastfeeding success, enhance bonding, stabilize infant
temperature and blood glucose, and promote maternal oxytocin
release. Delaying breastfeeding may reduce these benefits.
6. A deep latch helps prevent:
A. Increased milk production
B. Infant hiccups
C. Nipple pain and trauma
D. Neonatal jaundice
Answer: C. Nipple pain and trauma
Rationale: A deep latch allows the infant to compress the milk sinuses
effectively while minimizing pressure directly on the nipple. A shallow
latch often results in sore nipples, poor milk transfer, and ineffective
feeding. A deep latch does not directly prevent jaundice or hiccups.
