Reproductive System Exam Questions
1. Which of the following is a function of the placenta?
- A. The placenta secretes insulin.
- B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
- C. The placenta provides immunological protection to the fetus.
- D. The placenta stores fat-soluble vitamins for the fetus.
Correct answer: B
Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.
2. How do contraceptive oral pills help in birth control?
- A. Preventing ovulation
- B. Killing ova
- C. Killing sperms
- D. More than one of the above
Correct answer: A
Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.
3. Which hormone regulates the production of milk after childbirth?
- A. Prolactin
- B. Oxytocin
- C. Estrogen
- D. Progesterone
Correct answer: A
Rationale: The correct answer is Prolactin. Prolactin is the hormone responsible for regulating the production of milk after childbirth. It stimulates the mammary glands in the breasts to produce milk. Oxytocin, on the other hand, is responsible for the ejection of milk from the breasts. Estrogen and progesterone play roles in the menstrual cycle and pregnancy but are not directly involved in milk production. Therefore, choices B, C, and D are incorrect.
4. After fertilization, cell division occurs through a process of:
- A. Binary fission
- B. Meiosis
- C. Budding
- D. Mitosis
Correct answer: D
Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.
5. Legislation allowing nursing staff to provide contraceptives has resulted in all of the following EXCEPT:
- A. More nursing staff have been trained to provide family planning services
- B. Many population and family planning organizations have emerged
- C. Enhanced implementation of population and family planning programs
- D. Male involvement in family planning services
Correct answer: D
Rationale: The correct answer is D. Male involvement in family planning services has not significantly resulted from legislation allowing nursing staff to provide contraceptives. While legislation has led to more nursing staff being trained, the emergence of population and family planning organizations, and enhanced implementation of programs, it has not directly impacted male involvement in family planning.
