Reproductive System Exam Quizlet
1. Which hormone is primarily responsible for the development of female secondary sexual characteristics?
- A. Progesterone
- B. Testosterone
- C. Estrogen
- D. Oxytocin
Correct answer: C
Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
2. Lactational Amenorrhoea Method (LAM) is best for:
- A. Clients who do not wish to have any more children
- B. Clients with a baby less than 6 months postpartum
- C. Clients who want to wait before having a first or another child
- D. Clients with several sexual partners
Correct answer: B
Rationale: The correct answer is B: Clients with a baby less than 6 months postpartum. Lactational Amenorrhoea Method (LAM) is a highly effective temporary family planning method that is recommended for women who have recently given birth and are breastfeeding. LAM works best when the baby is less than 6 months old, the mother is exclusively breastfeeding, and her menstrual periods have not resumed. Choices A, C, and D are incorrect because LAM is specifically designed for postpartum women with infants less than 6 months old, focusing on the lactational infertility that occurs during exclusive breastfeeding.
3. What term is used to refer to the fertilized ovum?
- A. Zygote
- B. Embryo
- C. Foetus
- D. Pregnancy
Correct answer: A
Rationale: The correct answer is A, Zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is the initial stage of prenatal development. Choice B, Embryo, refers to the stage of prenatal development after the zygote and before the foetus. Choice C, Foetus, is the stage of prenatal development after the embryo. Choice D, Pregnancy, is a broader term referring to the condition of having a developing baby in the uterus.
4. What is one role of the hormone estrogen?
- A. Stimulates the development of the milk-producing tissue.
- B. Stimulates the production of lactoferrin.
- C. Stimulates the development of the nipple and duct system in the breast.
- D. Stimulates the secretion of relaxin.
Correct answer: A
Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.
5. Which phase of the menstrual cycle is variable?
- A. Ovulatory
- B. Regenerative
- C. Secretory
- D. Menstrual
Correct answer: B
Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.
