CSP Breastfeeding & Infant Feeding Practices 1 — Questions and Answers
Question 1: According to the American Academy of Pediatrics (AAP), what is the recommended duration for exclusive breastfeeding in healthy term infants?
- 3 months
- 4 months
- 6 months (Correct answer)
- 12 months
Correct answer: 6 months
The AAP recommends exclusive breastfeeding for approximately 6 months, followed by continued breastfeeding with complementary foods through at least 12 months.
Question 2: Which immunoglobulin is present in the highest concentration in human colostrum, providing passive immunity to the newborn?
- IgM
- IgA (Correct answer)
- IgG
- IgE
Correct answer: IgA
Secretory IgA (sIgA) is the predominant immunoglobulin in colostrum and mature breast milk, protecting the infant's mucosal surfaces against pathogens.
Question 3: At what age should vitamin D supplementation (400 IU/day) be initiated in exclusively breastfed infants?
- At birth
- Within a few days of birth (Correct answer)
- At 1 month of age
- At 2 months of age
Correct answer: Within a few days of birth
The AAP recommends that exclusively breastfed infants begin vitamin D supplementation of 400 IU/day within the first few days of life since human milk contains insufficient vitamin D.
Question 4: Iron supplementation (1 mg/kg/day) is recommended for exclusively breastfed full-term infants beginning at what age?
- 1 month
- 4 months (Correct answer)
- 6 months
- No supplementation needed before solid foods
Correct answer: 4 months
The AAP recommends starting iron supplementation at 4 months for exclusively breastfed full-term infants to prevent iron deficiency, since breast milk iron alone becomes insufficient around this time.
Question 5: Which component of human milk is primarily responsible for its bifidogenic effect, promoting growth of Bifidobacterium in the infant gut?
- Lactoferrin
- Human milk oligosaccharides (HMOs) (Correct answer)
- Secretory IgA
- Lysozyme
Correct answer: Human milk oligosaccharides (HMOs)
Human milk oligosaccharides (HMOs) are prebiotic structures that selectively promote growth of beneficial Bifidobacterium species in the infant intestinal microbiome.
Question 6: When preparing powdered infant formula for a healthy term newborn, what is the standard reconstitution ratio using the manufacturer's scoop?
- 1 unpacked scoop per 1 oz water
- 1 unpacked scoop per 2 oz water (Correct answer)
- 1 packed scoop per 2 oz water
- 2 unpacked scoops per 4 oz water
Correct answer: 1 unpacked scoop per 2 oz water
Standard infant formula is prepared by adding one level (unpacked) scoop of powder to 2 ounces of water to yield approximately 20 kcal/oz.
Question 7: Which of the following is a contraindication to breastfeeding in the United States?
- Maternal hepatitis B infection
- Maternal cytomegalovirus (CMV) seropositivity
- Maternal HIV infection (Correct answer)
- Maternal mastitis
Correct answer: Maternal HIV infection
In the United States, maternal HIV infection is a contraindication to breastfeeding due to the risk of HIV transmission to the infant through breast milk.
