A teen asks about the interval between ovulation and menstruation. Which of the following response of the nurse is TRUE? Approximately __ day.
Correct Answer
D. 14
Explanation
The correct answer is 14. The nurse is stating that the interval between ovulation and menstruation is approximately 14 days. This is a true statement as the average length of the luteal phase, which is the time between ovulation and menstruation, is typically around 14 days.
3.
Which of the following organs is responsible for releasing gonadotropins?
Correct Answer
B. Pituitary gland
Explanation
The pituitary gland is responsible for releasing gonadotropins. Gonadotropins are hormones that stimulate the function of the gonads, which include the ovaries in females and testes in males. The pituitary gland produces and releases hormones that regulate various functions in the body, including reproductive processes. In this case, it releases gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which play a crucial role in the development and function of the ovaries and testes.
4.
Which two statements below are TRUE regarding the process of ovulation.1) At birth, each ovary contains 400,000 underdeveloped ova2) Before puberty, the primordial cells produce estrogen3) Normally, only one ovum matures in each cycle4) The formation of primordial cells continue until puberty
Correct Answer
D. 3 and 4
Explanation
At 28 weeks AOG there are approximately 6,000,000 growing follicles. This continues to decrease as fetus reaches maturation: Term 1 million follicles; menarche 400,000 follicles; at 40 years old 8,000 follicles.Estrogen is sectreted primarily by ovaries and adrenal cortex to produce the menstrual cycle.
5.
Which phase of the menstrual cycle is characterized by a surge in Luteinizing Hormone from the pituitary gland?
Correct Answer
D. Secretory
Explanation
During the secretory or luteal phase the uterus is prepared for implantation. There is an increased estrogen and progesterone from corpus luteum.Also LH stimulates the development of corpus luteum (source of progesterone)
6.
At the beginning of menstruation, the following physiologic changes occur, EXCEPT?
Correct Answer
C. Luteinizing hormone is at its peak.
Explanation
During menstruation, the ovum does not begin to mature in the graafian follicle, as this process occurs during the follicular phase of the menstrual cycle. Estrogen and progesterone are indeed at their lowest level during menstruation. FSH (follicle-stimulating hormone) has just begun to rise, as it is responsible for stimulating the growth of follicles in the ovaries. However, luteinizing hormone (LH) is not at its peak during menstruation. LH surge occurs later in the menstrual cycle, specifically during the ovulatory phase, to trigger ovulation.
7.
After the first three months of pregnancy the chief source of estrogen and progesterone is the:
Correct Answer
B. Placenta
Explanation
During the first three months of pregnancy, the corpus luteum produces estrogen and progesterone, which are essential for maintaining the pregnancy. However, after this period, the placenta takes over as the chief source of these hormones. The placenta is an organ that develops during pregnancy and is responsible for providing oxygen and nutrients to the fetus. It also produces hormones that support the growth and development of the pregnancy, including estrogen and progesterone. Therefore, the correct answer is placenta.
8.
In the fetal blood vessels, the oxygen content is highest in the:
Correct Answer
C. Ductus venosus
Explanation
The structures involved in fetal circulation are: 1) umbilical vein; 2) umbilical arteries; 3) ductus venosus; 4) foramen ovale and 5) ductus arteriosus
9.

10.
In prenatal development, the growth is most rapid in the:
Correct Answer
D. Third trimester
Explanation
The first trimester is the period of organogenesis. The second trimester is the most comfortable for the mother with continued fetal growth. The third trimester has most period of rapid growth due to rapid deposition of fats and rapid iron and calcium deposition.
