Reproductive System Exam Quizlet
1. 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.
2. What is one of the roles of the oxytocin hormone?
- A. Stimulates milk ejection.
- B. Stimulates the production of milk.
- C. Stimulates the development of lactoferrin.
- D. Stimulates the secretion of relaxin.
Correct answer: A
Rationale: The correct answer is A: 'Stimulates milk ejection.' Oxytocin is responsible for contracting the muscles around the milk ducts, pushing milk into the nipples for breastfeeding. This process is known as milk ejection or let-down. The other choices are incorrect because oxytocin's primary function is to facilitate milk ejection rather than directly stimulating the production of milk, the development of lactoferrin, or the secretion of relaxin.
3. What action does the copper used in Copper T have?
- A. Blastocidal
- B. Bacteriostatic
- C. Bacteriocidal
- D. Spermicidal
Correct answer: D
Rationale: The correct answer is D, Spermicidal. The copper in Copper T exerts its action by affecting sperm viability and motility, thus preventing fertilization. Choices A, B, and C are incorrect because Copper T primarily works by preventing sperm from reaching and fertilizing the egg, rather than acting on blastocysts, bacteria, or bacteriocins.
4. 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.
5. What is the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births?
- A. 0.1
- B. 0.2
- C. 0.3
- D. 0.4
Correct answer: D
Rationale: To calculate the estimated percentage of deaths due to unsafe abortions, you divide the number of deaths due to unsafe abortions by the total number of maternal deaths and then multiply by 100 to get the percentage. In this case, with 591 maternal deaths and 40% estimated to be due to unsafe abortions, the calculation is (591 * 0.4) / 100, which equals 2.36. Therefore, the estimated percentage of deaths due to unsafe abortions from 591 maternal deaths per 100,000 live births is 0.4 or 40%. Choices A, B, and C are incorrect percentages that do not reflect the provided information.
