ALPP CLC CERTIFICATION EXAM 2026/2027 | CERTIFIED
LACTATION COUNSELOR | 100 VERIFIED Q&A | DETAILED
RATIONALES | PASS GUARANTEED – A+ GRADED
SECTION 1: ANATOMY AND PHYSIOLOGY OF LACTATION – Questions 1–15
Q1: Anatomy – Breast Structure
The student is reviewing breast anatomy. Which structure is responsible for milk production?
A. Lactiferous ducts
B. Alveoli
C. Nipple
D. Areola
Correct Answer: B
Rationale: Alveoli are the milk-producing cells clustered in lobules. Lactiferous ducts transport milk
to the nipple. The nipple and areola are external structures. [100% CORRECT]
Q2: Anatomy – Lobules
The student is reviewing breast anatomy. What are lobules?
A. Clusters of alveoli
B. Milk ducts
C. Fatty tissue
D. Connective tissue
Correct Answer: A
Rationale: Lobules are clusters of alveoli that produce milk. They are connected to ducts that carry
milk to the nipple. [100% CORRECT]
Q3: Physiology – Prolactin
The student is reviewing hormones. Which hormone is primarily responsible for milk production?
A. Oxytocin
B. Prolactin
C. Estrogen
D. Progesterone
Correct Answer: B
Rationale: Prolactin, secreted by the anterior pituitary, stimulates milk production (lactogenesis).
Oxytocin is responsible for milk ejection (let-down). [100% CORRECT]
Q4: Physiology – Oxytocin
The student is reviewing hormones. Which hormone is responsible for the milk ejection reflex (let-
down)?
,2
A. Prolactin
B. Oxytocin
C. Estrogen
D. Progesterone
Correct Answer: B
Rationale: Oxytocin, secreted by the posterior pituitary, causes myoepithelial cells around the
alveoli to contract, ejecting milk. [100% CORRECT]
Q5: Physiology – Lactogenesis I
The student is reviewing lactogenesis. When does lactogenesis I begin?
A. During pregnancy
B. After delivery
C. At puberty
D. During menopause
Correct Answer: A
Rationale: Lactogenesis I begins during pregnancy when the breast develops the capacity to produce
milk. Lactogenesis II begins after delivery with copious milk production. [100% CORRECT]
Q6: Physiology – Lactogenesis II
The student is reviewing lactogenesis. When does lactogenesis II occur?
A. During pregnancy
B. 2–5 days postpartum
C. 2 weeks postpartum
D. 6 months postpartum
Correct Answer: B
Rationale: Lactogenesis II occurs 2–5 days postpartum, marked by copious milk production (the milk
“coming in”). [100% CORRECT]
Q7: Physiology – Lactogenesis III
The student is reviewing lactogenesis. What characterizes lactogenesis III?
A. Established milk production
B. Colostrum production
C. Breast development
D. Weaning
Correct Answer: A
Rationale: Lactogenesis III is the maintenance phase of milk production, regulated by supply and
demand. [100% CORRECT]
Q8: Anatomy – Areola
The student is reviewing breast anatomy. What is the function of the areola?
A. To protect the nipple
, 3
B. To produce milk
C. To store milk
D. To transport milk
Correct Answer: A
Rationale: The areola contains Montgomery glands that secrete lubricating oil to protect the nipple
and areola. It also helps the infant latch. [100% CORRECT]
Q9: Anatomy – Montgomery Glands
The student is reviewing breast anatomy. What is the purpose of Montgomery glands?
A. To produce milk
B. To secrete lubricant
C. To transport milk
D. To store milk
Correct Answer: B
Rationale: Montgomery glands are sebaceous glands on the areola that secrete a lubricating fluid to
keep the nipple and areola supple and protect against infection. [100% CORRECT]
Q10: Physiology – Milk Synthesis
The student is reviewing milk synthesis. What is the primary substrate for milk synthesis?
A. Glucose
B. Protein
C. Fat
D. Water
Correct Answer: A
Rationale: Glucose is the primary substrate for lactose synthesis in milk. Other components are
derived from maternal blood. [100% CORRECT]
Q11: Physiology – Feedback Inhibitor of Lactation
The student is reviewing milk regulation. What is the Feedback Inhibitor of Lactation (FIL)?
A. A protein that stimulates milk production
B. A protein that inhibits milk production when milk accumulates
C. A hormone that stimulates let-down
D. A hormone that inhibits let-down
Correct Answer: B
Rationale: FIL is a whey protein that accumulates in milk; when milk is not removed, FIL signals the
breast to reduce milk production. [100% CORRECT]
Q12: Anatomy – Milk Ducts
The student is reviewing breast anatomy. What is the function of lactiferous ducts?
A. To produce milk
B. To transport milk to the nipple
