1. A term newborn is 2 hours old and has not yet latched effectively. The
mother reports that the infant becomes sleepy at the breast after a few
sucks. What is the MOST appropriate initial intervention?
A. Begin routine formula supplementation
B. Encourage immediate skin-to-skin contact and assess positioning and latch
C. Restrict breastfeeding to every 4 hours
D. Give the infant water before attempting breastfeeding
Correct Answer: B
Explanation: Skin-to-skin contact promotes infant physiologic stability,
feeding behaviors, and early breastfeeding. The IBCLC should first assess the
dyad, including infant positioning, maternal comfort, latch, suck, and transfer
of milk. A sleepy newborn does not automatically require supplementation.
Formula or expressed milk may become appropriate if clinically indicated, but
the underlying breastfeeding difficulty should first be assessed and addressed.
2. During a breastfeeding assessment, the mother reports sharp nipple
pain throughout the entire feeding. The infant's lips are tightly pursed
around the nipple, and only a small portion of the areola is in the infant's
mouth. Which finding MOST likely explains the pain?
A. Deep latch with effective milk transfer
B. Shallow latch with excessive nipple compression
C. Normal newborn sucking behavior
D. Excessive milk production
Correct Answer: B
Explanation: A shallow latch commonly causes nipple compression and
significant pain because the nipple is positioned improperly within the
infant's mouth. The IBCLC should help the mother reposition the infant and
encourage a deeper latch, with more breast tissue drawn into the infant's
1|Page
,mouth. Persistent nipple pain should not simply be considered a normal part
of breastfeeding.
3. A breastfeeding parent asks how often a healthy newborn should
generally breastfeed during the first weeks of life. Which response is
MOST appropriate?
A. Every 6 hours on a strict schedule
B. Only when the breasts feel full
C. Frequently and responsively, commonly around 8–12 times in 24 hours
D. Exactly 4 times during the day and twice overnight
Correct Answer: C
Explanation: Most healthy newborns breastfeed frequently, often
approximately 8–12 times in 24 hours, although individual patterns vary.
Responsive feeding allows the parent to respond to early feeding cues rather
than waiting for intense crying. Frequent milk removal also helps establish
and maintain milk production. Strict schedules can unnecessarily restrict
feeding opportunities.
4. A mother reports that her nipples are becoming sore during the first
week postpartum. Which observation would provide the MOST useful
information about the cause of the soreness?
A. The mother's preferred breastfeeding position
B. The infant's latch, positioning, and sucking pattern
C. The mother's daily fluid intake alone
D. The infant's birth weight alone
Correct Answer: B
Explanation: Nipple pain is best evaluated by observing an actual feeding.
The IBCLC should assess alignment, infant positioning, latch depth, tongue and
jaw movement, nipple shape after feeding, and maternal comfort. These
observations can identify mechanical causes of nipple trauma. Hydration and
2|Page
,birth weight may be relevant to overall care but do not directly explain most
mechanical nipple pain.
5. A breastfeeding parent notices that the breasts become softer after
several days of frequent breastfeeding and worries that milk production
is decreasing. What is the BEST explanation?
A. Softer breasts always indicate inadequate milk production
B. The breasts normally become less engorged as milk production becomes
regulated
C. Breastfeeding should immediately be stopped
D. The infant should automatically receive formula
Correct Answer: B
Explanation: During the early postpartum period, breasts may become very
full as milk production increases. Over time, milk production becomes more
closely regulated according to milk removal, and the breasts may feel softer
even when milk production is adequate. Breast softness alone is therefore not
a reliable indicator of insufficient milk. Infant output, weight trends, feeding
behavior, swallowing, and milk transfer provide more useful information.
6. A newborn has difficulty maintaining a latch and repeatedly slips off
the breast. Which intervention should the IBCLC consider FIRST?
A. Evaluate positioning and attachment during a feeding
B. Recommend immediate weaning
C. Tell the parent to limit feeds to 5 minutes
D. Give the infant glucose water before every feeding
Correct Answer: A
Explanation: Difficulty maintaining attachment requires assessment of the
breastfeeding mechanics. The IBCLC should observe positioning, alignment,
latch depth, infant oral function, maternal breast anatomy, and milk flow.
Correcting positioning and attachment may resolve the problem without
3|Page
, unnecessary supplementation. If the problem persists, additional assessment
for oral-motor or anatomical factors may be indicated.
7. A breastfeeding infant is producing progressively more wet diapers
and has transitioned from meconium to yellow, seedy stools. What does
this pattern MOST strongly suggest?
A. Increasing milk intake
B. Severe dehydration
C. Complete breastfeeding failure
D. Intestinal obstruction
Correct Answer: A
Explanation: Increasing urine output and the transition from meconium to
lighter, yellow stools are expected signs of increasing milk intake during the
early neonatal period. Diaper patterns should be interpreted together with
feeding behavior, clinical examination, and weight changes. Stool and urine
output are useful indicators of intake but should not be considered in
isolation.
8. A parent asks whether breastfeeding should continue when the infant
wants to feed frequently during an evening period. The infant is
otherwise healthy and gaining appropriately. What is the MOST
appropriate response?
A. Frequent evening feeding can be normal and may be part of cluster feeding
B. The parent should refuse all feeds after 6 p.m.
C. The infant should automatically receive formula
D. Frequent feeding always means the parent has no milk
Correct Answer: A
Explanation: Cluster feeding refers to periods when an infant breastfeeds
repeatedly over a relatively short period. It can occur normally, particularly
during certain times of the day. Frequent feeding does not automatically
indicate inadequate milk production. The IBCLC should assess the infant's
