A nurse is reinforcing teaching with a group of clients about taking recommended folic acid supplements prior to conception and throughout pregnancy as primary prevention. Which of the following conditions can occur in the neonate as the result of folic acid deficiency?

A. Hyperbilirubinemia: Hyperbilirubinemia in neonates is commonly due to immature liver function and the breakdown of red blood cells after birth. It is not linked to maternal folic acid deficiency and would not be prevented through maternal folic acid supplementation. B. Hyperemesis gravidarum: Hyperemesis gravidarum is a severe form of nausea and vomiting that occurs during pregnancy, affecting the mother rather than the neonate. Folic acid supplementation does not prevent this condition, as it is more related to hormonal changes during pregnancy. C. Iron deficiency anemia: Iron deficiency anemia occurs when there is an inadequate amount of iron, not folic acid, in the mother’s or infant’s diet. While iron is important during pregnancy for both the mother and the developing fetus, folic acid deficiency primarily affects neural tube development, not iron levels or red blood cell production in the same way. Iron supplementation is recommended during pregnancy to prevent iron deficiency anemia. D. Neural tube defects: Neural tube defects, such as spina bifida and anencephaly, are directly linked to folic acid deficiency during early pregnancy. Adequate folic acid intake before conception and during early pregnancy significantly reduces the risk of these serious birth defects affecting the brain and spine.
