The nurse is discussing vitamins with a group of pregnant women at a community center when one of the participants asks, "What vitamin deficiency during pregnancy is a frequent cause of spina bifida in newborn infants?"
The nurse correctly responds by stating:
1. Folic acid (vitamin B9)
2. Cyanocobalamin (vitamin B12)
3. Ascorbic acid (vitamin C)
4. Manganese
Correct Answer: 1
Rationale 1: Studies indicate that birth defects such as spina bifida can be prevented with folic acid supplementation during pregnancy.
Rationale 2: Cyanocobalamin (vitamin B12) deficiency does not cause neural tube defects such as spina bifida.
Rationale 3: Spina bifida is not associated with ascorbic acid (vitamin C) deficiency.
Rationale 4: Manganese deficiency during pregnancy does not cause spina bifida in newborn infants.
Global Rationale: Folic acid (vitamin B9), is often highlighted as a need in pregnancy because it prevents birth defects such as spina bifida, other neural tube problems, and congenital heart conditions. Because birth defects can take place early in pregnancy, taking prenatal vitamins is recommended if a woman is trying to get pregnant.
Vitamin C, manganese, and vitamin B12 are not implicated in this protection.
