How does the nurse explain the fetal period of development to a pregnant client?

The fetal period of development is an important stage that occurs from the ninth week of gestation until birth. This timeframe is characterized by significant growth and maturation of the fetus, primarily involving the development of body systems, organs, and overall size. During this period, the fetus continues to develop and refine its physical features, as well as prepare for functions necessary for life outside the womb, such as breathing and feeding.

Given that this period extends over several months until delivery, it is indeed the longest phase in the entire prenatal development timeline. This growth phase is vital because many essential developments continue during this time, including the development of organs that were initiated in the embryonic stage. Understanding this context helps emphasize the significance of the fetal period in comparing it to earlier stages, such as the embryonic period, which is shorter and encompasses the initial formation of the organs.
