1. A lactation consultant working in a Maryland maternity unit is
reviewing the physiology of lactogenesis with a newly hired nurse. The
consultant explains that Lactogenesis II, characterized by copious milk
production and breast fullness, is primarily triggered by which
physiologic event occurring after childbirth?
A. Increased estrogen secretion from the placenta
B. Sharp decline in progesterone following placental delivery
C. Increased fetal prolactin transfer to maternal circulation
D. Suppression of oxytocin release during labor
B. Sharp decline in progesterone following placental delivery
The delivery of the placenta causes progesterone levels to fall
dramatically, allowing prolactin to stimulate copious milk production
during Lactogenesis II. Elevated progesterone during pregnancy inhibits
full milk secretion despite high prolactin levels.
2. A postpartum mother reports severe nipple pain during breastfeeding
and states that the infant “clicks” repeatedly while nursing. Upon
observation, the lactation consultant notes shallow latch and poor
tongue extension. Which condition should be suspected first?
,A. Neonatal jaundice
B. Mastitis
C. Ankyloglossia
D. Galactocele
C. Ankyloglossia
Ankyloglossia, commonly called tongue-tie, restricts tongue movement
and often causes shallow latch, maternal nipple trauma, clicking sounds,
and ineffective milk transfer. Proper assessment of infant oral anatomy is
essential in breastfeeding difficulties.
3. A lactation consultant is counseling a mother whose infant was born at
30 weeks’ gestation. The consultant explains that expressed human
milk is especially beneficial for premature infants because it
significantly reduces the risk of which serious neonatal condition?
A. Congenital hypothyroidism
B. Necrotizing enterocolitis
C. Patent ductus arteriosus
D. Retinopathy of prematurity
B. Necrotizing enterocolitis
Human milk provides immunologic and anti-inflammatory protection that
markedly decreases the incidence and severity of necrotizing enterocolitis
in premature infants. This is one of the most important clinical benefits of
breast milk in neonatal intensive care settings.
4. During a breastfeeding assessment, a lactation consultant observes
rhythmic suck-swallow-breathe coordination in a healthy term infant.
Which finding indicates effective milk transfer?
A. Infant cheeks dimpling inward continuously
B. Audible swallowing after every one or two sucks
C. Persistent maternal nipple blanching
D. Infant sleeping within one minute of latch
,B. Audible swallowing after every one or two sucks
Audible swallowing and coordinated sucking patterns indicate effective
milk transfer. Persistent cheek dimpling, nipple trauma, and immediate
infant fatigue may suggest poor latch or ineffective feeding.
5. A mother taking chemotherapy medication asks whether
breastfeeding may continue safely. What is the lactation consultant’s
most appropriate response?
A. Breastfeeding is safe if feedings occur six hours after medication
administration
B. Pumping and discarding milk is unnecessary during chemotherapy
C. Most chemotherapy agents are contraindicated during breastfeeding
D. Breastfeeding may continue if the infant is older than six months
C. Most chemotherapy agents are contraindicated during breastfeeding
Chemotherapy medications are generally contraindicated during
breastfeeding because many cytotoxic agents enter breast milk and may
seriously harm the infant by affecting rapidly dividing cells and immune
function.
6. A lactation consultant teaches a mother hand expression techniques
during the immediate postpartum period. Which advantage is most
strongly associated with hand expression during the first few days
after birth?
A. Increased formula tolerance
B. Reduced neonatal bilirubin levels exclusively
C. Improved colostrum collection and breast stimulation
D. Prevention of infant reflux disease
C. Improved colostrum collection and breast stimulation
Hand expression is highly effective in the early postpartum period because
colostrum is thick and produced in small quantities. It enhances breast
, stimulation, supports milk production, and facilitates collection of valuable
colostrum for the newborn.
7. A breastfeeding mother develops fever, unilateral breast pain,
erythema, and flu-like symptoms. Which condition is most consistent
with these findings?
A. Plugged duct
B. Raynaud phenomenon
C. Mastitis
D. Engorgement
C. Mastitis
Mastitis commonly presents with localized breast redness, pain, swelling,
fever, and systemic flu-like symptoms. It is often associated with milk stasis
and bacterial infection, requiring prompt management and continued milk
removal.
8. A mother states that her infant breastfeeds every hour during the
evening but sleeps longer stretches overnight. Which explanation
should the lactation consultant provide?
A. The infant is demonstrating abnormal neurologic reflexes
B. Cluster feeding commonly occurs during periods of rapid growth and
evening fussiness
C. Frequent evening feeds always indicate inadequate milk supply
D. The infant is developing lactose intolerance
B. Cluster feeding commonly occurs during periods of rapid growth and
evening fussiness
Cluster feeding is a normal infant behavior characterized by frequent
feedings over short periods, especially during evenings or growth spurts. It
helps stimulate milk production and does not necessarily indicate low milk
supply.
