1. What is "Colostrum"?
a) A formula brand
b) The first thick, yellow milk produced immediately after birth
c) Milk produced after 6 months
d) A type of baby bottle
Expand Text
Answer: b) The first thick, yellow milk produced immediately after birth
Often called "Liquid Gold," it is low in volume but extremely rich in antibodies and protein to protect the newborn's immune system.
2. According to the World Health Organization (WHO), how long should infants be "exclusively" breastfed?
a) 1 month
b) 3 months
c) First 6 months
d) 1 year
Expand Text
Answer: c) First 6 months
"Exclusive" means no other food or water, only breast milk. After 6 months, complementary foods should be introduced while continuing breastfeeding.
3. Which hormone is primarily responsible for the *production* of milk?
a) Estrogen
b) Prolactin
c) Oxytocin
d) Insulin
Expand Text
Answer: b) Prolactin
Produced by the pituitary gland, Prolactin levels rise when the baby sucks, signaling the alveoli to make more milk for the next feed.
4. Which hormone triggers the "Let-down reflex" (milk ejection)?
a) Adrenaline
b) Oxytocin
c) Progesterone
d) Cortisol
Expand Text
Answer: b) Oxytocin
Known as the "Love Hormone," it causes the tiny muscles around the milk glands to squeeze milk into the ducts. Stress can inhibit this reflex.
5. What is the difference between "Foremilk" and "Hindmilk"?
a) Foremilk is hot; Hindmilk is cold
b) Foremilk is watery/thirst-quenching; Hindmilk is higher in fat/calories
c) Hindmilk comes first
d) No difference
Expand Text
Answer: b) Foremilk is watery/thirst-quenching; Hindmilk is higher in fat/calories
The milk gradually becomes creamier as the feed progresses. Hindmilk is crucial for the baby's weight gain and satiety.
6. Which specific antibody is abundant in breast milk and protects the baby's gut?
a) IgE
b) IgA (Secretory Immunoglobulin A)
c) IgG
d) IgM
Expand Text
Answer: b) IgA (Secretory Immunoglobulin A)
It coats the lining of the baby's intestines, preventing harmful bacteria and viruses from entering the bloodstream.
7. Breastfeeding significantly reduces the mother's risk of developing:
a) Lung Cancer
b) Breast and Ovarian Cancer
c) Brain Tumor
d) Skin Cancer
Expand Text
Answer: b) Breast and Ovarian Cancer
Lactation lowers estrogen levels and prevents ovulation for a period, which is protective against reproductive cancers.
8. Which vitamin is typically low in breast milk and usually requires supplementation for the baby?
a) Vitamin C
b) Vitamin D
c) Vitamin A
d) Calcium
Expand Text
Answer: b) Vitamin D
While breast milk is near-perfect, it often lacks sufficient Vitamin D (the sunshine vitamin), leading to a risk of rickets if not supplemented.
9. "Lactational Amenorrhea Method" (LAM) refers to:
a) A method to increase milk
b) Natural contraception (birth control) due to breastfeeding
c) A breast infection
d) Baby refusing milk
Expand Text
Answer: b) Natural contraception (birth control) due to breastfeeding
Exclusive, frequent breastfeeding delays the return of menstruation and ovulation, acting as 98% effective birth control for the first 6 months.
10. "Mastitis" is a condition characterized by:
a) Too much milk
b) Painful inflammation or infection of the breast tissue
c) Baby biting
d) Dry skin
Expand Text
Answer: b) Painful inflammation or infection of the breast tissue
Usually caused by a blocked milk duct or bacteria entering a cracked nipple. Symptoms include fever, red streaks, and a hard lump.
11. What is the "Rooting Reflex"?
a) Baby kicking legs
b) Baby turning head and opening mouth when the cheek is stroked
c) Baby crying
d) Baby sleeping
Expand Text
Answer: b) Baby turning head and opening mouth when the cheek is stroked
This is a natural instinct in newborns to help them find the nipple and latch on for feeding.
12. "Galactosemia" in an infant is one of the few absolute medical reasons to:
a) Breastfeed more
b) Avoid breastfeeding completely
c) Add sugar to milk
d) Warm the milk
Expand Text
Answer: b) Avoid breastfeeding completely
It is a rare genetic disorder where the baby cannot metabolize galactose (a sugar in milk). Breastfeeding these babies can be fatal.
13. How long can freshly expressed breast milk be safely stored at room temperature?
a) 1 hour
b) 4 hours
c) 12 hours
d) 24 hours
Expand Text
Answer: b) 4 hours
According to CDC guidelines, it is safe for up to 4 hours at room temp (77°F/25°C), 4 days in the fridge, and 6-12 months in the freezer.
14. Does the size of the breast determine the amount of milk a mother can produce?
a) Yes, larger breasts make more milk
b) No, breast size is fatty tissue; glandular tissue determines supply
c) Only left breast makes milk
d) Yes, small breasts cannot breastfeed
Expand Text
Answer: b) No, breast size is fatty tissue; glandular tissue determines supply
Almost all women have enough glandular tissue to produce milk. Size differences are mostly due to fat storage, which doesn't affect milk yield.
15. Breastfeeding helps the mother's uterus return to its pre-pregnancy size. This process is called:
a) Involution
b) Ovulation
c) Evolution
d) Gestation
Expand Text
Answer: a) Involution
Oxytocin released during breastfeeding causes uterine contractions, shrinking the uterus faster and reducing postpartum bleeding.
16. What is "Cluster Feeding"?
a) Feeding many babies at once
b) A baby wanting to eat very frequently (e.g., every hour) for a few hours
c) Feeding only at night
d) Feeding solid food
Expand Text
Answer: b) A baby wanting to eat very frequently (e.g., every hour) for a few hours
This is normal behavior, often happening in the evening or during growth spurts to boost the mother's milk supply.
17. "Montgomery Glands" are the small bumps on the areola that function to:
a) Look pretty
b) Secrete an oily substance to lubricate and protect the nipple
c) Produce milk
d) Detect temperature
Expand Text
Answer: b) Secrete an oily substance to lubricate and protect the nipple
This natural oil discourages bacterial growth. Washing nipples with harsh soap removes this protection and causes cracking.
18. Breastfeeding is linked to a reduced risk of which potentially fatal infant condition?
a) Acne
b) SIDS (Sudden Infant Death Syndrome)
c) Jaundice
d) Hiccups
Expand Text
Answer: b) SIDS (Sudden Infant Death Syndrome)
Studies show breastfeeding lowers SIDS risk by ~50%, possibly because breastfed babies arouse from sleep more easily.
19. How does breast milk change during the night?
a) It becomes sour
b) It contains higher levels of Melatonin (sleep hormone)
c) It turns blue
d) It has caffeine
Expand Text
Answer: b) It contains higher levels of Melatonin (sleep hormone)
Nighttime milk helps regulate the baby's circadian rhythm and encourages sleep, unlike formula which is the same 24/7.
20. "Nipple Confusion" (Flow Preference) can happen if:
a) The baby is held wrong
b) Artificial nipples/bottles are introduced too early
c) The mother eats spicy food
d) The baby sleeps too much
Expand Text
Answer: b) Artificial nipples/bottles are introduced too early
Bottle flow is faster and easier. If introduced before breastfeeding is established, the baby may reject the breast because it requires more work.
21. Does a breastfeeding mother need to drink cow's milk to make breast milk?
a) Yes, absolutely
b) No, calcium is drawn from her reserves if diet is lacking
c) Only chocolate milk
d) Yes, 1 liter a day
Expand Text
Answer: b) No, calcium is drawn from her reserves if diet is lacking
Milk is not required to make milk. A mother can produce high-quality milk even on a varied diet without dairy, though she should ensure calcium intake.
22. "Tongue-Tie" (Ankyloglossia) in a baby can cause:
a) Excessive crying
b) Difficulty latching and nipple pain for the mother
c) Fever
d) Hiccups
Expand Text
Answer: b) Difficulty latching and nipple pain for the mother
A tight band of tissue tethers the tongue tip to the floor of the mouth, preventing the baby from sucking effectively.
23. "World Breastfeeding Week" is celebrated annually in:
a) January 1-7
b) August 1-7
c) December 1-7
d) May 1-7
Expand Text
Answer: b) August 1-7
It is a global campaign coordinated by the World Alliance for Breastfeeding Action (WABA) to promote and support breastfeeding.
24. Colostrum acts as a natural laxative to help the newborn pass:
a) Urine
b) Meconium (First stool)
c) Gas
d) Blood
Expand Text
Answer: b) Meconium (First stool)
Clearing meconium quickly helps reduce the risk of newborn jaundice by excreting excess bilirubin from the body.
25. Can a mother with the common flu continue to breastfeed?
a) No, she must stop
b) Yes, her milk provides antibodies to protect the baby
c) Only if she boils the milk
d) Only once a day
Expand Text
Answer: b) Yes, her milk provides antibodies to protect the baby
The mother's body creates specific antibodies to fight the flu, which pass into the milk. She should wear a mask and wash hands to prevent airborne transmission.
