Document Summary
Estrogen levels are the highest during the proliferative phase of the endometrial cycle, when the endometrial glands enlarge in response to increasing amounts of estrogen. Progesterone is the predominant hormone of the secretory phase. Levels of estrogen and progesterone drop sharply during the ischemic phase and fall during the menstrual phase. After teaching a group of adolescent girls about female reproductive development, the nurse determines that teaching was successful when the girls state that menarche is defined as a woman"s first: Menarche is defined as the establishment of menstruation. It does not refer to the woman"s first sexual experience, full hormonal cycle, or sign of breast development. A client with a 28-day cycle reports that she ovulated on may 10. The nurse would expect the client"s next menses to begin on: For a woman with a 28-day cycle, ovulation typically occurs on day 14.
