Question 1 of 5
A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?
Correct Answer: A
Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections.
Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old.
Choice C is incorrect as infants are not shielded from all infections due to their immature immune system.
Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.
