Reproductive System Exam Questions
1. What does the umbilical cord contain?
- A. Pluripotent stem cells
- B. Cord blood stem cells
- C. Blood stem cells
- D. None of the above
Correct answer: B
Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.
2. The endometrium is shed up to the basal layer during this phase of the menstrual cycle:
- A. Ovulation
- B. Regenerative
- C. Secretory
- D. Menstruation
Correct answer: D
Rationale: The correct answer is D. During the menstrual phase of the menstrual cycle, the endometrium is shed up to the basal layer. This shedding occurs as a result of decreased levels of estrogen and progesterone, leading to the breakdown and subsequent shedding of the endometrial lining. Choice A, ovulation, is incorrect as ovulation is the release of an egg from the ovary, which occurs during the mid-cycle. Choice B, regenerative, is incorrect as it does not specifically refer to the phase where the shedding of the endometrium occurs. Choice C, secretory, is incorrect as it refers to the phase where the endometrium thickens in preparation for possible implantation of a fertilized egg, not shedding.
3. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'
4. What does MTP stand for?
- A. Medical Termination of Parturition
- B. Mechanical Transfer of Pollen
- C. Medical Termination of Pregnancy
- D. Maternally Transmitted Pathogens
Correct answer: C
Rationale: The correct expansion for MTP is Medical Termination of Pregnancy. This term is commonly used in healthcare to refer to the procedure of ending a pregnancy. Choices A, B, and D are incorrect because they do not accurately represent the expansion of the abbreviation MTP. Choice A refers to labor induction, choice B is related to plant reproduction, and choice D deals with the transmission of pathogens from mother to offspring.
5. What prompted Zambia to implement family planning services?
- A. The nation started to experience the effects of rapid population growth on the economy and individual welfare.
- B. Donors provided free family planning pills.
- C. Mothers were delivering twice a year.
- D. There were too many abortions.
Correct answer: A
Rationale: The correct answer is A. Rapid population growth's impact on the economy and individual welfare prompted Zambia to implement family planning services. This is because a rapidly growing population can strain resources, lead to unemployment, poverty, and inadequate access to healthcare. Choice B is incorrect because the provision of free family planning pills by donors may have been a subsequent intervention rather than the initial reason for implementing family planning services. Choice C is irrelevant as the frequency of deliveries by mothers does not directly relate to the implementation of family planning services. Choice D is also incorrect as high abortion rates may be a consequence of inadequate family planning services rather than the reason for their implementation.
