Name one maternal condition that can affect prenatal development.

• A. Maternal diabetes
• B. Maternal epilepsy
• C. Maternal asthma
• D. Maternal hypertension

Answer: (B)

The key idea is that the intrauterine environment created by maternal health can influence fetal development. Conditions that alter this environment, especially metabolic or vascular factors, can affect how organs form and grow. Maternal diabetes is a well-established example because high glucose levels during early pregnancy can interfere with normal organogenesis, increasing the risk of congenital heart defects, neural tube defects, and other anomalies, as well as growth problems. Good glycemic control before and during pregnancy markedly reduces these risks. By contrast, maternal epilepsy by itself isn’t a direct developmental risk—the concern there is mainly about exposure to certain anti-seizure medications that can be teratogenic. Asthma isn’t inherently a developmental teratogen, though medication choices and ensuring adequate oxygenation are important. Maternal hypertension can lead to placental issues and fetal growth restriction, but it’s less about congenital malformations and more about growth and timing. So a maternal condition that clearly demonstrates impact on prenatal development is diabetes, due to its direct effect on the intrauterine environment during organ formation.
