Which of the following are examples of environmental factors that can cause developmental delays?

• A. Poor maternal nutrition
• B. Exposure to toxins
• C. Infections passed from mother to baby during pregnancy
• D. All of the above

Answer: (D)

Development can be affected by factors in the surrounding environment, especially during pregnancy. Poor maternal nutrition can deprive the developing fetus of essential nutrients needed for brain growth, increasing the risk of developmental delays. Exposure to toxins—such as lead, certain chemicals, alcohol, or drugs—can interfere with normal brain development and function. Infections passed from mother to baby during pregnancy, like certain TORCH infections, can damage the developing nervous system and lead to delays or disabilities. Because each of these is an environmental factor that can influence fetal development, the best answer is all of the above. In practice, supporting good prenatal nutrition, minimizing toxin exposure, and preventing or managing infections during pregnancy are important steps a direct care worker can help with, along with monitoring and early intervention if developmental concerns arise.
