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 C

Explanation

Choice A Reason: 3-2-1-0-2. This is an incorrect answer that underestimates the number of pregnancies and overestimates the number of preterm births. The client has had four pregnancies, not three. She has had one preterm birth, not two.

Choice B Reason: 4-1-1-1-3. This is an incorrect answer that overestimates the number of living children. The client has two living children, not three.

Choice C Reason 4-1-1-1-2. This is because the GTPAL method is a way of summarizing a woman's obstetric history using five numbers: G (gravida), T (term births), P (preterm births), A (abortions), and L (living children). Gravida is the number of pregnancies, regardless of outcome. Term births are deliveries after 37 weeks' gestation. Preterm births are deliveries between 20 and 37 weeks' gestation. Abortions are pregnancies that end before 20 weeks' gestation, either spontaneously or electively. Living children are the number of children who are alive at the time of assessment.

Choice D Reason: 4-1-2-0-3. This is an incorrect answer that overestimates the number of preterm births and living children, and underestimates the number of abortions. The client has had one preterm birth, not two. She has had one abortion, not zero. She has two living children, not three.

A. Frequent voiding encourages sphincter control. B. A full bladder impedes oxygen ﬂow to the fetus. C. Frequent voiding prevents bruising of the bladder. D. A full bladder can impede fetal descent.

Correct Answer is D

Explanation

Choice A Reason: Frequent voiding encourages sphincter control. This is an incorrect statement that has no relevance to labor and delivery. Sphincter control refers to the ability to contract and relax the muscles that control urination and defecation. It is not aﬀected by frequent voiding.

Choice B Reason: A full bladder impedes oxygen ﬂow to the fetus. This is an incorrect statement that confuses a full bladder with a prolapsed cord. A prolapsed cord is a condition where the umbilical cord slips through the cervix before the baby and becomes compressed by the fetal head, which can reduce oxygen ﬂow to the fetus. A full bladder does not aﬀect oxygen ﬂow to the fetus.

Choice C Reason: Frequent voiding prevents bruising of the bladder. This is an incorrect statement that exaggerates the eﬀect of a full bladder on the bladder wall. A full bladder may cause some pressure or discomfort on the bladder, but it does not cause bruising or damage.

Choice D Reason: A full bladder can impede fetal descent. This is a correct statement that explains why it is important for the nurse to assess the bladder regularly and encourage the laboring client to void every 2 hours.
