The nurse instructs a pregnant client that the purpose of an amniocentesis at 36 weeks gestation is for:

Choice A rationale

Increasing folic acid intake immediately is recommended because it helps prevent neural tube defects, which can occur very early in pregnancy, often before a woman knows she is pregnant.

Choice B rationale

Starting folic acid intake one week before her period is not sufficient. Folic acid needs to be taken consistently before conception and during early pregnancy to be effective.

Choice C rationale

Waiting until pregnancy is confirmed may be too late to prevent neural tube defects, which form in the early weeks of pregnancy.

Choice D rationale

If she misses her period, it might already be too late to prevent neural tube defects. Consistent intake of folic acid before and during early pregnancy is essential.

Choice A rationale

Iron needs significantly increase during pregnancy to support the increased blood volume, the formation of the placenta, and the growth of the fetus. Pregnant women often require additional iron to prevent anemia and ensure adequate oxygen transport to the baby.

Choice B rationale

While calcium requirements do increase during breastfeeding to support milk production, this statement is not directly related to the nutritional needs during pregnancy. The focus during pregnancy should be on adequate intake of nutrients that support both maternal and fetal health.

Choice C rationale

Vitamin E requirements do not decline during pregnancy. In fact, the need for antioxidants like vitamin E may increase to protect both the mother and developing fetus from oxidative stress.

Choice D rationale

While prenatal vitamins are important for meeting various nutritional needs during pregnancy, they do not always provide sufficient vitamin D. Some women may need additional supplementation based on their dietary intake, sun exposure, and individual health needs.
