PCE - Certified Breastfeeding Counselor (CBC) Exam V1
Newest Actual Exam Questions, Verified Answers, and
Clinical Rationales 2026/2027 Edition
Question 1
Which hormone is primarily responsible for the synthesis of milk within the
alveolar epithelial cells of the mammary gland during lactation?
A. Prolactin
B. Oxytocin
C. Progesterone
D. Estrogen
Correct Answer: A. Prolactin
Clinical Rationale: Prolactin, synthesized and secreted by the anterior pituitary
gland, is the primary hormone driving milk production (lactogenesis) by
stimulating alveolar epithelial cells. Oxytocin is responsible for milk ejection.
Question 2
A breastfeeding mother expresses concern that her milk supply is diminishing
because her breasts no longer feel constantly engorged. What is the most
appropriate counseling response?
A. Reassure her that breasts becoming softer after the first few weeks is normal
as supply regulates to infant demand.
B. Advise her to immediately start supplementing with iron-fortified infant
formula after every nursing session.
C. Tell her to restrict nursing intervals to exactly four hours to allow milk to
accumulate in the ducts.
, D. Recommend immediate cessation of breastfeeding due to secondary lactation
failure.
Correct Answer: A. Reassure her that breasts becoming softer after the first
few weeks is normal as supply regulates to infant demand.
Clinical Rationale: Initial engorgement subsides after the first few weeks as the
milk supply transitions from endocrine control to autocrine control (supply-and-
demand feedback loop). Soft breasts do not indicate low supply.
Question 3
An infant is brought in for a two-week postpartum evaluation. The mother reports
nursing every two to three hours, but the infant has not yet returned to birth weight
and has infrequent mustard-colored stools. What is the most critical initial
assessment?
A. Observe a complete breastfeeding session to evaluate latch, positioning, and
milk transfer.
B. Instruct the mother to switch immediately to exclusive bottle feeding with
expressed formula.
C. Prescribe synthetic progestin hormone pills to stimulate maternal endocrine
production.
D. Recommend discontinuing night feedings to prevent maternal sleep
deprivation.
Correct Answer: A. Observe a complete breastfeeding session to evaluate
latch, positioning, and milk transfer.
Clinical Rationale: Direct observation of a breastfeeding session is the gold
standard for identifying mechanical issues such as poor latch, ineffective suckling,
or incorrect positioning that impair milk transfer.
Question 4
Which anatomical structure of the infant's oral cavity provides the primary vacuum
seal during an optimal deep latch on the breast?
, A. The flanged lips resting well outside the areola, with the lower lip everted
B. The sharp anterior alveolar ridge pressing directly against the nipple tip
C. The hard palate sealing the roof of the mouth against the nasal cavity
D. The tip of the tongue curled upward behind the upper gums
Correct Answer: A. The flanged lips resting well outside the areola, with the
lower lip everted
Clinical Rationale: A deep latch requires wide opening of the infant's mouth so
that the lips flange outward (especially the lower lip) and seal against a large
portion of the lower breast tissue, not just the nipple.
Question 5
A postpartum mother is diagnosed with mastitis in her left breast. She expresses
fear that continuing to breastfeed will harm her infant. What is the standard
medical and lactation guidance?
A. Continue frequent breastfeeding or milk removal on the affected side, as
emptying the breast is essential for recovery.
B. Immediately cease all nursing from both breasts and pump and dump until
antibiotics are finished.
C. Apply tight elastic bandages to compress the infected breast tissue and
suppress milk flow.
D. Provide the infant exclusively with cow milk substitutes until maternal
symptoms resolve.
Correct Answer: A. Continue frequent breastfeeding or milk removal on the
affected side, as emptying the breast is essential for recovery.
Clinical Rationale: Frequent and effective removal of milk from the affected
breast is a cornerstone of mastitis treatment. It prevents stasis, reduces pressure,
and is entirely safe for the nursing infant.
Question 6
, Which reflex is stimulated when the infant's cheek or lips are stroked, causing the
head to turn toward the stimulus and the mouth to open wide?
A. Rooting reflex
B. Moro reflex
C. Babinski reflex
D. Tonic neck reflex
Correct Answer: A. Rooting reflex
Clinical Rationale: The rooting reflex is a primitive survival reflex that helps the
newborn locate the nipple and position the mouth for a wide latch when perioral
structures are touched.
Question 7
What is the primary immunological component found in human colostrum that
provides passive local mucosal protection in the neonatal gastrointestinal tract?
A. Secretory immunoglobulin A
B. Immunoglobulin E antibodies
C. High-density lipoprotein complexes
D. Fibrinogen clotting factors
Correct Answer: A. Secretory immunoglobulin A
Clinical Rationale: Colostrum is exceptionally rich in secretory immunoglobulin
A, which coats the infant's immature mucosal lining, neutralizing pathogens and
preventing adherence of foreign antigens without provoking systemic
inflammation.
Question 8
A breastfeeding mother complains of severe, sharp, shooting pain in her breasts
during and after feedings, accompanied by flaky, shiny skin on the nipples and
white patches in the infant's oral cavity. What condition is most likely present?
