Which statement made by a pregnant patient indicates teaching was effective related to an elevated alpha fetoprotein (AFP) level?

A. Incorrect → Low AFP, not high AFP, is associated with Down syndrome. B. Incorrect → An elevated AFP does not guarantee spina bifida—further testing (e.g., ultrasound, amniocentesis) is needed. C. Incorrect → It is incorrect to say the baby has spina bifida without confirmation. D. Correct → Elevated AFP is associated with neural tube defects, such as spina bifida. However, it only suggests an increased risk, not a definite diagnosis.
