Which of the following is a positive prognostic advance in spina bifida management?

• A. Antibiotics
• B. Ventricular shunts
• C. Clean intermittent catheterization
• D. Awareness of folic acid in pregnancy

Answer: (D)

Preventive intake of folic acid before conception and in early pregnancy dramatically lowers the risk of neural tube defects like spina bifida, which makes it the strongest positive prognostic advance. By supporting proper neural tube closure during the earliest weeks of development, folic acid reduces the number of affected pregnancies and often lessens severity when defects still occur, improving overall outcomes for babies. Other options help manage problems after birth—antibiotics address infections, ventricular shunts treat hydrocephalus, and catheterization aids bladder function—but they do not prevent the condition or shift prognosis as powerfully as preventing the defect with folic acid.
