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.

Answer and Explanation

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 A

Explanation

Choice A Reason: Inspecting the placenta after delivery for intactness. This is because inspecting the placenta after delivery for intactness is a nursing intervention that can prevent late postpartum hemorrhage, which is excessive bleeding from the uterus or genital tract that occurs more than 24 hours but less than 12 weeks after delivery. Late postpartum hemorrhage can be caused by retained placental fragments, subinvolution of the uterus, infection, or coagulation disorders. Inspecting the placenta after delivery for intactness can help identify and remove any retained placental fragments that may interfere with uterine contraction and involution, which are essential for hemostasis.

Choice B Reason: Manually removing the placenta at delivery. This is an incorrect answer that indicates an inappropriate and risky intervention that can cause late postpartum hemorrhage. Manually removing the placenta at delivery is a procedure that involves inserting a hand into the uterus and detaching the placenta from the uterine wall. Manually removing the placenta at delivery is indicated only for a retained or adherent placenta that does not separate spontaneously or with gentle traction within 30 minutes after delivery. Manually removing the placenta at delivery can cause trauma, infection, or incomplete removal of the placenta, which can increase the risk of late postpartum hemorrhage.

Choice C Reason: Administering broad-spectrum antibiotics prophylactically. This is an incorrect answer that suggests an unnecessary and ineﬀective intervention that can prevent late postpartum hemorrhage. Administering broad- spectrum antibiotics prophylactically is a pharmacological intervention that involves giving antibiotics to prevent or treat infection. Administering broad-spectrum antibiotics prophylactically is indicated for women with risk factors or signs of infection during or after delivery, such as prolonged rupture of membranes, chorioamnionitis, fever, or foul- smelling lochia. Administering broad-spectrum antibiotics prophylactically may reduce the risk of infection-related late postpartum hemorrhage, but it does not address other causes of late postpartum hemorrhage such as retained placental fragments or subinvolution of the uterus.

Choice D Reason: Applying traction on the umbilical cord to speed up separation of the placenta. This is an incorrect answer that refers to a diﬀerent intervention that can prevent early postpartum hemorrhage, not late postpartum hemorrhage. Applying traction on the umbilical cord to speed up separation of the placenta is a technique that involves pulling on the umbilical cord while applying counter pressure on the uterus to facilitate placental expulsion. Applying traction on the umbilical cord to speed up separation of the placenta is indicated for active management of the third stage of labor, which can prevent early postpartum hemorrhage, which is excessive bleeding from the uterus or genital tract that occurs within 24 hours after delivery. Early postpartum hemorrhage can be caused by uterine atony, retained placenta, lacerations, or coagulation disorders.

A. "Our baby's newborn rash is from this syndrome." B. "His face looks like it does due to this problem." C. "He can show signs of withdrawal from alcohol exposure like jiteriness, sweating, hyper reﬂexes, poor feeding and not sleeping well." D. "He is at risk of having intellectual disabilities, so we will need to get extra services to support him."

Correct Answer is A

Explanation

Choice A Reason: "Our baby's newborn rash is from this syndrome." This is because this statement by a parent indicates that additional teaching is required, as it shows a misunderstanding or confusion about FAS and its manifestations. FAS is a condition that occurs when a woman consumes alcohol during pregnancy, which can aﬀect the development and function of various organs and systems in the fetus and child. FAS can cause physical, behavioral, and cognitive problems such as facial abnormalities, growth retardation, learning difficulties, and atention deficits. FAS does not cause newborn rash, which is a common and benign condition that aﬀects many newborns regardless of maternal alcohol intake. Newborn rash is also known as erythema toxicum neonatorum or baby acne, which is characterized by small red bumps or pustules on the face, chest, or back that usually disappear within a few weeks.

Choice B Reason: "His face looks like it does due to this problem." This is a correct answer that indicates adequate understanding of FAS and its features. Facial abnormalities are one of the characteristic signs of FAS, which include small eye openings, thin upper lip, ﬂat nasal bridge, and smooth philtrum (the groove between the nose and upper lip).

Choice C Reason: "He can show signs of withdrawal from alcohol exposure like jiteriness, sweating, hyper reﬂexes, poor feeding and not sleeping well." This is a correct answer that indicates adequate understanding of FAS and its complications. Signs of withdrawal are possible eﬀects of FAS, which occur when the fetus or newborn is exposed to alcohol in utero or through breast milk, which can cause neurotoxicity and dependency. Signs of withdrawal can include jiteriness, sweating, hyper reﬂexes, poor feeding, and not sleeping well, as well as irritability, seizures, or tremors.

Choice D Reason: "He is at risk of having intellectual disabilities, so we will need to get extra services to support him." This is a correct answer that indicates adequate understanding of FAS and its implications. Intellectual disabilities are potential outcomes of FAS, which aﬀect the cognitive development and function of the child. Intellectual disabilities can cause problems with memory, Reasoning, language, and social skills. Extra services and support may be needed to help the child achieve their optimal potential and quality of life.
