Certified Lactation Specialist Lactation Specialist Hospital & Community-Based Lactation Care 3 — Questions and Answers
Question 1: A lactation specialist is training hospital nursing staff. Which statement MOST accurately describes the let-down (milk ejection) reflex?
- It is triggered by prolactin and causes alveolar cells to produce milk
- It is triggered by oxytocin and causes myoepithelial cells to contract and eject milk (Correct answer)
- It is triggered by estrogen and is inhibited by skin-to-skin contact
- It only occurs during the first week postpartum
Correct answer: It is triggered by oxytocin and causes myoepithelial cells to contract and eject milk
Oxytocin causes myoepithelial cells surrounding alveoli to contract, ejecting milk toward the nipple.
Question 2: A community lactation specialist receives a call from a mother concerned her milk supply is low. Which indicator is MOST reliable for assessing adequate infant milk intake?
- The mother's perception of breast fullness
- Number of wet and dirty diapers combined with infant weight gain (Correct answer)
- Duration of each nursing session
- Infant sleeping through the night by 2 weeks
Correct answer: Number of wet and dirty diapers combined with infant weight gain
Adequate wet diapers (6+ per day after day 4), stool output, and appropriate weight gain are the most reliable indicators of sufficient intake.
Question 3: A hospital lactation consultant is asked about galactagogues for a mother with low milk supply. What is the MOST evidence-based initial approach?
- Prescribe domperidone immediately
- Maximize milk removal frequency and effectiveness before considering pharmacological galactagogues (Correct answer)
- Recommend fenugreek supplements as first-line treatment
- Advise the mother that nothing can be done if supply is low
Correct answer: Maximize milk removal frequency and effectiveness before considering pharmacological galactagogues
Increasing milk removal frequency and ensuring effective latch is the cornerstone of supply management before pharmacological agents.
Question 4: Which clinical finding would raise concern for ankyloglossia (tongue-tie) in a breastfeeding newborn?
- Infant feeds for 40 minutes per session with adequate weight gain
- Heart-shaped tongue tip, restricted tongue elevation, and maternal nipple pain or compression after feeds (Correct answer)
- Infant has a strong suck reflex during digital exam with full tongue mobility
- Infant has a high palate only, with no restriction of tongue movement
Correct answer: Heart-shaped tongue tip, restricted tongue elevation, and maternal nipple pain or compression after feeds
A heart-shaped tongue, limited elevation, and maternal nipple trauma are hallmarks of ankyloglossia affecting breastfeeding.
Question 5: When counseling a mother in a community setting about returning to work, what is the MOST important lactation management strategy?
- Switch to formula at 6 weeks to simplify the return-to-work transition
- Maintain supply by pumping at work at times the infant would normally feed, and store milk properly (Correct answer)
- Only pump once a day to gradually reduce supply
- Introduce solids early to compensate for reduced breastfeeding sessions
Correct answer: Maintain supply by pumping at work at times the infant would normally feed, and store milk properly
Pumping at the frequency the infant would normally nurse helps maintain supply and provides breast milk while separated.
Question 6: A postpartum mother on the maternity unit has type 1 diabetes and is breastfeeding. What important consideration should the lactation specialist communicate?
- Breastfeeding is contraindicated in type 1 diabetes
- Breastfeeding may reduce maternal insulin requirements and helps lower infant risk of obesity and diabetes (Correct answer)
- The infant must receive formula supplementation due to maternal blood sugar variability
- Glucose levels are unaffected by lactation in type 1 diabetes
Correct answer: Breastfeeding may reduce maternal insulin requirements and helps lower infant risk of obesity and diabetes
Breastfeeding lowers maternal insulin needs and confers metabolic benefits to both mother and infant.
Question 7: A lactation specialist is reviewing a hospital's breastfeeding data. Which metric BEST evaluates the impact of lactation support services?
- Number of lactation consultant visits per shift
- Exclusive breastfeeding rates at discharge and at 2-month well-child visits (Correct answer)
- Total formula units distributed in the nursery
- Average length of postpartum hospital stay
Correct answer: Exclusive breastfeeding rates at discharge and at 2-month well-child visits
Exclusive breastfeeding rates at discharge and follow-up are the gold-standard outcome metrics for lactation support quality.
