An 8-month pregnant woman asks the nurse, Does my baby have any antibodies to fight infection? The most appropriate response by the nurse is:
 
  1. Your baby has all the immunoglobulins it will needIgG, IgM, and IgA..
  2. Your baby won't receive any antibodies until it is born and you breastfeed..
  3. Your baby does not have any antibodies to fight infection..
  4. Your baby has IgG and IgM immunoglobulins..

Question 2

At 35 weeks of pregnancy, a woman experiences preterm labor. Although tocolytics are administered and she is placed on bed rest, she continues to experience regular uterine con-tractions and her cervix is beginning to dilate and efface.
 
  What would be an important test for fetal well-being at this time? 1. Percutaneous umbilical blood sampling
  2. Ultrasound for fetal size
  3. Amniocentesis for fetal lung maturity
  4. Nonstress test

Answer to Question 1

4
1. Incorrect. During the third trimester, the only immunoglobulin that crosses the placenta, IgG, provides passive acquired immunity to specific bacterial toxins. The fetus produces IgM by the end of the first trimester. IgA immunoglobulins are not produced by the baby.
2. Incorrect. By the third trimester, the fetus has IgG and IgM. Breastfeeding will supply the baby with IgA immunoglobulins.
3. Incorrect. This is not an accurate statement. By the third trimester, the fetus has IgG and IgM.
4. Correct. During the third trimester, the only immunoglobulin that crosses the placenta, IgG, provides passive acquired immunity to specific bacterial toxins. The fetus produces IgM by the end of the first trimester.

Answer to Question 2

3
1. Incorrect. Indications for PUBS include prenatal diagnosis or inherited blood disorders, karyotyping of malformed fetuses, detection of fetal infection, determination of the acid-base status of the fetus with IUGR, and assessment and treatment of isoimmunization and thrombocytopenia in the fetus.
2. Incorrect. Determination of fetal size by ultrasound is typically done during the second trimester and is not indicated in this scenario.
3. Correct. An amniocentesis would be performed to assess fetal lung maturity in the event of a preterm birth.
4. Incorrect. A nonstress test measures the fetal response to fetal movement in a noncon-tracting mother.
