Question 1

A breastfeeding mother at 6 weeks postpartum presents with a wedge-shaped area of redness and warmth on her right breast and a temperature of 38.8°C. She does not feel systemically unwell. According to current evidence, what is the MOST important first management step?

  1. Advise temporary weaning from the affected breast to allow tissue recovery
  2. Apply vigorous deep breast massage to clear the inflammatory blockage
  3. Support continued frequent milk removal and recommend anti-inflammatory medication
  4. Begin a 10-day antibiotic course immediately, as fever indicates bacterial mastitis
Show answer & explanation

Correct answer: C - Support continued frequent milk removal and recommend anti-inflammatory medication

Question 2

A 4-day-old term infant presents with visible jaundice. The mother reports latching difficulties since birth and states her milk has not yet come in. The infant has produced only 2 wet diapers and 1 stool in the past 24 hours. Total serum bilirubin is 15 mg/dL. What type of jaundice is MOST likely, and what is the PRIMARY intervention?

  1. Breastfeeding jaundice; the priority is improving milk transfer by correcting latch and increasing feeding frequency
  2. Breast milk jaundice; advise the mother to temporarily discontinue breastfeeding for 24-48 hours to confirm the diagnosis
  3. Physiological jaundice; reassure the mother and schedule a routine review in 3 days
  4. Haemolytic jaundice; refer immediately for blood group incompatibility testing and phototherapy evaluation
Show answer & explanation

Correct answer: A - Breastfeeding jaundice; the priority is improving milk transfer by correcting latch and increasing feeding frequency

Question 3

A formula company representative offers to stock the maternity unit waiting room with informational brochures about their infant formula products at no charge. According to the WHO International Code of Marketing of Breast-milk Substitutes, what is the MOST appropriate response?

  1. Accept the offer, as free educational brochures benefit families without financial cost to the unit
  2. Accept only if the brochures also include messaging that promotes breastfeeding as the recommended first choice for all infants
  3. Seek hospital administrator approval before deciding, as the Code applies only to paid advertising
  4. Decline - distributing formula promotional materials in health facilities violates the Code
Show answer & explanation

Correct answer: D - Decline - distributing formula promotional materials in health facilities violates the Code

Question 4

A mother at 8 weeks postpartum reports that every time her infant begins to feed, she experiences a sudden intense wave of sadness and dread lasting approximately 60 seconds, which then completely disappears. She denies persistent low mood, loss of interest in her baby, or any symptoms between feeds. What condition does this MOST likely represent?

  1. Postpartum depression with a recurrent feed-triggered anxiety component - refer for psychiatric evaluation
  2. An oxytocin hypersensitivity reaction causing transient emotional instability at the moment of let-down
  3. Dysphoric Milk Ejection Reflex (D-MER)
  4. A conditioned emotional response to birth trauma, requiring therapeutic intervention before feeds continue
Show answer & explanation

Correct answer: C - Dysphoric Milk Ejection Reflex (D-MER)

Question 5

A mother gave birth 5 days ago and has been feeding her newborn every 4-5 hours, with one 6-hour overnight stretch, following advice from a family member. Her milk has come in but she is concerned about her long-term supply. What is the MOST important physiological reason why feeding frequency in the FIRST TWO WEEKS is uniquely critical?

  1. Prolactin levels are at their absolute peak in the first two weeks and must be continuously stimulated through suckling or they will decline permanently, reducing overall supply potential
  2. Frequent feeding upregulates prolactin receptors in the first two weeks, establishing long-term supply capacity
  3. Milk removal prevents FIL accumulation, which would otherwise permanently suppress prolactin secretion after day 14
  4. Final glandular differentiation of breast tissue occurs in the first two weeks and requires stimulation to complete
Show answer & explanation

Correct answer: B - Frequent feeding upregulates prolactin receptors in the first two weeks, establishing long-term supply capacity

Question 6

An IBCLC is assessing a 2-week-old infant with maternal nipple pain, a wedge-shaped nipple after feeds, and poor weight gain. On visual inspection, the infant's tongue elevates to mid-mouth and extends slightly past the lower gum ridge. Despite this apparently normal tongue movement, the latch remains shallow. What should the IBCLC do NEXT?

  1. Palpate beneath the tongue for a posterior frenulum not visible on inspection
  2. Reassure the mother - normal tongue elevation to mid-mouth confirms that ankyloglossia is not contributing to the presentation and repositioning alone is sufficient
  3. Refer the infant for a frenotomy based on the clinical signs of nipple trauma and poor weight gain
  4. Introduce a nipple shield as a longer-term protective measure while the infant's oral skills mature
Show answer & explanation

Correct answer: A - Palpate beneath the tongue for a posterior frenulum not visible on inspection

Question 7

After a breastfeed, an IBCLC observes that the mother's nipple is flattened with a distinct pale stripe across the tip - resembling a new lipstick just uncapped. The mother reports significant pain throughout the entire feed. What does this finding MOST likely indicate?

  1. A normal post-feed variation in nipple shape that resolves within minutes as the tissue returns to its resting state and does not warrant intervention
  2. Nipple blanching from Raynaud's phenomenon triggered by temperature change when the infant releases the breast
  3. Surface damage from a candida infection, which causes nipple flattening and discolouration at the tip
  4. Compressive force from a shallow latch - the nipple is being pinched against the hard palate
Show answer & explanation

Correct answer: D - Compressive force from a shallow latch - the nipple is being pinched against the hard palate

Question 8

A mother of a 4-month-old calls to report that her milk supply has noticeably decreased over the past 3 days with no change in feeding frequency, no breast symptoms, and no new stressors. On questioning, she mentions she started a multi-symptom over-the-counter cold medication 4 days ago. Which ingredient is MOST likely responsible for her supply decrease?

  1. Guaifenesin, which thickens mucus secretions and can reduce milk fluidity
  2. Loratadine, which crosses into milk and reduces the infant's suckling drive
  3. Pseudoephedrine
  4. Dextromethorphan, which suppresses prolactin secretion via central dopamine pathways
Show answer & explanation

Correct answer: C - Pseudoephedrine

Question 9

A healthy term newborn is placed in uninterrupted skin-to-skin contact immediately after birth. Thirty minutes later, the infant is in the crawling stage of Widström's nine instinctive stages and beginning to approach the breast. The bedside nurse states the infant needs to be weighed, measured, and given vitamin K before becoming too sleepy. What is the MOST appropriate action?

  1. Weigh, measure, and administer vitamin K immediately, then return the infant to the chest to attempt latching
  2. Delay all routine procedures until the infant has completed the full feeding sequence, which typically takes 60-90 minutes
  3. Administer vitamin K only - delaying it beyond 30 minutes carries a haemorrhagic risk - then weigh and measure after the feed
  4. Complete all assessments quickly to minimise total interruption time, then resume skin-to-skin
Show answer & explanation

Correct answer: B - Delay all routine procedures until the infant has completed the full feeding sequence, which typically takes 60-90 minutes

Question 10

A 3-day-old infant is diagnosed with classic galactosemia on newborn metabolic screening. The mother is eager to breastfeed and asks whether she may offer expressed breast milk for two feeds per day while the infant receives metabolic formula for the remainder. What is the MOST appropriate response?

  1. Support the partial breastfeeding plan - even a reduced human milk intake significantly lowers galactose exposure to a level the infant's body can safely manage
  2. Advise complete discontinuation - classic galactosemia is an absolute contraindication to human milk
  3. Confirm that breastfeeding is safe provided the metabolic formula remains the primary source of nutrition
  4. Trial partial breastfeeding for two weeks with close monitoring of blood galactose-1-phosphate levels
Show answer & explanation

Correct answer: B - Advise complete discontinuation - classic galactosemia is an absolute contraindication to human milk
