Question

A woman who is 8 months pregnant asks the nurse, "Does my baby have any antibodies to fight infection?" What is the most appropriate response by the nurse?

a."Your baby has all the immunoglobulins necessary: immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA)."
b."Your baby won't receive any antibodies until he is born and you breastfeed him."
c."Your baby does not have any antibodies to fight infection."
d."Your baby has IgG and IgM."

Answer 1

a."Your baby has all the immunoglobulins necessary: immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA)." During fetal development, antibodies are transferred from the mother to the fetus. The most appropriate response is that the baby has all the necessary immunoglobulins to fight infection. Immunoglobulin G (IgG) can cross the placenta and provide passive immunity, while immunoglobulin A (IgA) can be transferred through breast milk.

Step-by-step explanation:

The most appropriate response by the nurse would be option a. 'Your baby has all the immunoglobulins necessary: immunoglobulin G (IgG), immunoglobulin M (IgM), and immunoglobulin A (IgA).' During fetal development, antibodies are transferred from the mother to the fetus through the placenta. Immunoglobulin G (IgG) is the only antibody class that can cross the placenta and provide passive immunity to the fetus. This passive immune defense lasts up to six months after birth. Additionally, immunoglobulin A (IgA) can be transferred from the mother to the baby through breast milk, providing further immune protection.'
