A client whose previous pregnancy was affected by a neural tube defect is planning another pregnancy. Which teaching should the nurse provide?
1Wait until a home pregnancy test is positive before discussing folic acid dosing.
2Use a standard prenatal vitamin only and avoid discussing the prior pregnancy with the provider.
3Rely on leafy green vegetables alone because supplements are contraindicated after a prior neural tube defect.
4Consult the provider about folic acid 4,000 mcg daily from 1 month before conception through month 3 of pregnancy.✓ Correct answer
Explanation
For a client with a previous neural tube defect-affected pregnancy, CDC guidance recommends discussing a higher folic acid dose with the healthcare provider: 4,000 mcg daily starting 1 month before conception and continuing through the first 3 months of pregnancy (option 4). Waiting for a positive pregnancy test can miss the early period of neural-tube development. A standard prenatal vitamin alone may not supply the recommended high-risk dose, and dietary folate does not replace the prescribed supplement plan.
Clinical Judgment Recognize the prior neural tube defect-affected pregnancy as a high-risk cue. The timing is preconception, not after pregnancy is recognized.
Memory Tip Prior NTD: 4,000 mcg daily, start 1 month before conception, continue through the first 3 months.
Clinical Practice GuideA prior neural tube defect-affected pregnancy places the client in a higher-risk group that needs preconception counseling about folic acid dosing and timing.
Folic Acid — A B vitamin important for early fetal neural tube development.
Neural Tube Defect — A birth defect involving incomplete closure of the brain or spinal cord structures.
Preconception Care — Health planning before pregnancy to reduce risks.
