A nurse is caring for a client who is in the first stage of labor, undergoing external fetal monitoring, and receiving IV fluid. The nurse observes variable decelerations in the fetal heart rate on the monitor strip. Which of the following is a correct interpretation of this finding?

A. "Increase your intake of ironrich foods and take a prenatal vitamin."
Important, but not directly related to reducing the risk of neural tube defects. Ironrich foods and prenatal vitamins are essential for overall maternal and fetal health, but they do not specifically target neural tube defect prevention.
B. "Avoid any alcohol consumption."
Important advice during pregnancy to prevent fetal alcohol spectrum disorders, but not directly related to reducing the risk of neural tube defects.
C. "Take a folic acid supplement for at least 3 months before you get pregnant."
Correct: Adequate folic acid intake before conception and during early pregnancy can significantly reduce the risk of neural tube defects in newborns.
D. "Avoid all foods containing aspartame."Aspartame is an artificial sweetener that has been studied for safety in pregnancy, and there is currently no strong evidence linking it to neural tube defects. However, it's still a good idea
to limit the intake of artificial sweeteners during pregnancy and focus on a balanced diet.

Choice A: Fetal lung maturity is not assessed through maternal serum alphafetoprotein testing. It is usually evaluated through tests such as amniocentesis or specialized ultrasound examinations closer to the third trimester.
Choice B: The maternal serum alphafetoprotein test specifically screens for certain birth defects and genetic conditions in the fetus, rather than general signs of physical and physiological
wellbeing.

Choice C: The maternal serum alphafetoprotein test is not used to identify Rh incompatibility. Rh incompatibility is determined through blood tests that assess the Rh factor of the mother's blood and the Rh status of the baby.
Choice D: The maternal serum alphafetoprotein test is a blood screening test that can identify neural tube defects (such as spina bifida) and chromosomal abnormalities (such as Down syndrome) in the fetus. The test measures the levels of alphafetoprotein in the mother's blood, and abnormal levels may indicate the need for further diagnostic testing.
