What defines a teratogen?

A teratogen is defined as an agent that causes malformation of an embryo or fetus during fetal development. This definition is crucial for understanding the implications of exposure to various substances or environmental factors during pregnancy, as teratogens can lead to a range of developmental abnormalities or congenital disorders.

For instance, teratogens can include certain drugs, alcohol, infections, radiation, and chemicals that have the potential to disrupt normal development. It is important for healthcare providers to counsel pregnant individuals regarding the risks associated with known teratogens to minimize the potential for harm to the developing fetus. Understanding what constitutes a teratogen is key for nursing practice, as it informs prenatal care and risk assessment for pregnant patients.
