Domain I: Development and Nutrition (Questions 1-20)
Question 1
In a term infant, the normal weight gain during the first month of life is
approximately:
A) 5 g/day
B) 15 g/day
C) 30 g/day
D) 45 g/day
Correct ,,,,Answer,,,,: B) 15 g/day ✅
Rationale: Term infants typically gain about 15-30 g per day during the
first month. The average is approximately 150-200 g per week, which
equals about 21-28 g/day. Moderate hypocaloric intake is approximately
5-10 g/day, while 15 g/day is within the typical range for exclusively
breastfed term infants.
,Question 2
Which of the following is the normal stool pattern for a term infant
exclusively breastfed during the first month?
A) Hard, pellet-like stools daily
B) Watery, green stools with each feed
C) Yellow, seedy stools 3-4 times per day
D) Bloody stools after feeds
Correct ,,,,Answer,,,,: C) Yellow, seedy stools 3-4 times per day ✅
Rationale: Breastfed infants commonly pass soft, yellow, "seedy" stools
several times daily in the first weeks. The seedy appearance comes from
undigested milk fat. Hard stools indicate constipation; green watery
stools may indicate foremilk-hindmilk imbalance; bloody stools require
immediate evaluation.
Question 3
At what postnatal age does the infant typically develop the ability to self-
regulate milk flow by adjusting tongue position?
A) 0-2 days
B) 1-2 weeks
C) 3-4 weeks
D) 6-8 weeks
Correct ,,,,Answer,,,,: C) 3-4 weeks ✅
Rationale: By 3-4 weeks of age, the infant's oral musculature matures,
allowing subtle tongue movements that modulate milk flow. This
developmental milestone enables the baby to more effectively manage
,fast let-down or low flow. Prior to this, the suck pattern is more primitive
and less adaptable.
Question 4
Colostrum is present beginning in which trimester of pregnancy?
A) First trimester
B) Second trimester
C) Third trimester
D) Only after delivery
Correct ,,,,Answer,,,,: B) Second trimester ✅
Rationale: Colostrogenesis begins as early as 12-16 weeks gestation
(second trimester). Alveolar cells differentiate and begin producing
colostrum under the influence of placental lactogen and prolactin, though
the volume remains small until after delivery.
Question 5
Which immunoglobulin is found in the highest concentration in
colostrum?
A) IgA
B) IgG
C) IgM
D) IgE
Correct ,,,,Answer,,,,: A) IgA ✅
, Rationale: Secretory IgA (sIgA) is the predominant immunoglobulin in
colostrum and mature human milk. It provides passive mucosal immunity
to the infant by coating the gastrointestinal tract and preventing pathogen
adherence. Colostrum contains up to 20 times more sIgA than mature
milk.
Question 6
Approximately what percentage of human milk is comprised of
carbohydrates (primarily lactose)?
A) 1-2%
B) 4-5%
C) 7-8%
D) 10-12%
Correct ,,,,Answer,,,,: C) 7-8% ✅
Rationale: Human milk contains approximately 7% carbohydrates,
primarily lactose, which provides about 40% of the calories. This is higher
than the carbohydrate content of cow's milk or most infant formulas. The
remaining composition includes approximately 4% fat and 1% protein.
Question 7
The primary carbohydrate in human milk is:
A) Glucose
B) Galactose
