What is the most appropriate nursing response about the cause of a newborn with myelomeningocele?

• A. One of the parents carries a defective gene that causes myelomeningocele.
• B. A deficiency in folic acid in the father is the most likely cause.
• C. There may be no definitive cause identified.
• D. There may be a genetic pattern that guarantees this in offspring.

Answer: (C)

The main idea here is that neural tube defects like myelomeningocele arise from multiple interacting factors in early fetal development, and there isn’t a single identifiable cause in many cases. Because of this multifactorial nature, it’s common that no definite cause can be pinpointed for a given newborn. Maternal folic acid status is a known influence on risk, and folate supplementation before conception and in early pregnancy can reduce that risk, but even with this factor, a definite cause may still not be identifiable and the outcome isn’t guaranteed. Genetics can play a role in increasing risk, but there isn’t a single defective gene or a simple inheritance pattern that guarantees this condition in offspring, so attributing it to one parent’s gene is not accurate. Likewise, paternal folic acid deficiency isn’t recognized as a cause, and there isn’t a genetic pattern that guarantees the condition in future children. So, the most accurate nursing response is that there may be no definitive cause identified. This reflects the real-world understanding that neural tube defects are often the result of multifactorial influences rather than a single, determinate factor.
