An nurse is counseling a new mother about the immunologic properties of breast milk. The nurse emphasizes that breast milk is the main source of which specific immunoglobulin?
Select one:
IgG.
IgE.
IgA.
IgM.
The Correct Answer is C
Choice A Reason: IgG. This is an incorrect answer that refers to a different type of antibody that is not abundant in breast milk. IgG is a type of antibody that provides systemic immunity against various antigens. IgG is found in low concentrations in breast milk, as it does not cross the mammary epithelium easily. IgG can protect the infant from some infections, but it is mainly transferred from the mother to the fetus through the placenta during pregnancy.
Choice B Reason: IgE. This is an incorrect answer that refers to a different type of antibody that is not relevant to breast milk. IgE is a type of antibody that mediates allergic reactions and parasitic infections. IgE is found in very low concentrations in breast milk, as it does not have a significant role in mucosal immunity. IgE can trigger mast cells and basophils to release histamine and other inflammatory mediators, which can cause symptoms such as itching, swelling, or bronchoconstriction.
Choice C Reason: IgA. This is because IgA is a type of antibody that protects mucosal surfaces from pathogens and toxins. IgA is found in high concentrations in breast milk, especially in colostrum (the first milk produced after delivery). IgA can bind to bacteria and viruses in the infant's gastrointestinal tract and prevent them from ataching to the intestinal wall or crossing into the bloodstream. IgA can also enhance the infant's immune system by stimulating lymphoid tissue development and modulating inflammatory responses.
Choice D Reason: IgM. This is an incorrect answer that refers to a different type of antibody that is not abundant in breast milk. IgM is a type of antibody that activates complement system and agglutinates antigens. IgM is found in low concentrations in breast milk, as it does not cross the mammary epithelium easily due to its large size. IgM can protect the infant from some infections, but it is mainly produced by the infant's own immune system in response to exposure to antigens.

Correct Answer is D
Explanation
Choice A Reason: Hyperglycemia and increased appetite. This is an incorrect answer that describes symptoms of diabetes mellitus, not sepsis. Diabetes mellitus is a chronic metabolic disorder where the body cannot produce or use insulin effectively, which results in high blood glucose levels and impaired glucose tolerance. Diabetes mellitus can affect newborns if the mother has pre-existing or gestational diabetes, which can cause macrosomia, hypoglycemia, or congenital anomalies.
Choice B Reason: Increased urinary output and spitting up mucous. This is an incorrect answer that indicates normal or benign conditions, not sepsis. Increased urinary output is a normal finding in newborns, as they eliminate the excess fluid that was accumulated during pregnancy. Spitting up mucous is a common occurrence in newborns, as they clear their airways of amniotic fluid or secretions.
Choice C Reason: Wakefulness and ruddy appearance. This is an incorrect answer that suggests healthy or normal characteristics, not sepsis. Wakefulness is a sign of alertness and responsiveness in newborns, which reflects their neurological development and adaptation. Ruddy appearance is a reddish color of the skin that is normal in newborns, especially in term or post-term infants, which indicates adequate oxygenation and hemoglobin levels.
Choice D Reason: Temperature instability and lethargy. This is because temperature instability and lethargy are common signs of sepsis in newborns, which indicate systemic infection and inflammation. Sepsis is a life-threatening condition where the body's response to infection causes tissue damage, organ failure, or death. Sepsis can occur in newborns due to maternal, fetal, or neonatal factors, such as chorioamnionitis, premature rupture of membranes, prolonged labor, invasive procedures, or bacterial colonization.
Correct Answer is D
Explanation
Choice A Reason: About 1 of every 5 women will experience abuse in her lifetime is a statistic that shows the prevalence of domestic violence, but it does not address the question of what the nurse should emphasize to the group of women.
Choice B Reason: When women go back to the situation after the abuser has calmed down, things will be beter is a false statement that reflects the cycle of abuse, where the abuser may apologize and promise to change after a violent episode, but then repeat the same behavior later. This does not help the women understand their situation or seek help.
Choice C Reason: The victimized woman can easily leave the situation is a false statement that ignores the many barriers and challenges that women face when trying to escape from domestic violence, such as fear, isolation, financial dependence, lack of support, legal issues, and threats from the abuser. This does not empower the women or provide them with realistic options.
Choice D Reason: The violence will not stop or decrease if the woman becomes pregnant is a true statement that highlights the danger of staying in an abusive relationship during pregnancy. Domestic violence can increase the risk of miscarriage, preterm birth, low birth weight, placental abruption, fetal injury, and maternal death. This may motivate the women to seek safety and protection for themselves and their unborn children.
