This special Week 1 review episode wraps up the most important content from Chapters 3, 4, and 5 in the Purple Maternal-Newborn Nursing series. We go over the menstrual cycle, conception, embryonic and fetal development, the role of genetics in childbearing, pregnancy diagnosis, and the early stages of prenatal care. You’ll also hear key terms, physiological changes, danger signs, and nursing priorities for supporting expectant patients during the first trimester. If you’re studying for a quiz or getting ready for clinicals, this episode brings it all together in one clear review.
