What is the role of the corpus luteum during the menstrual cycle?
- A. The corpus luteum produces estrogen to maintain the endometrium.
- B. The corpus luteum produces progesterone to maintain the endometrium.
- C. The corpus luteum produces testosterone to inhibit ovulation.
- D. The corpus luteum has no significant role during the menstrual cycle.
Correct Answer: B
Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

Rationale: A Total Fertility Rate of 6.2 means that a woman will give birth to an average of 6.2 children during her childbearing years. The correct answer is A as it accurately reflects the concept of Total Fertility Rate. Choice B is incorrect as it misinterprets the concept by equating it to a percentage of time being pregnant. Choice C is incorrect as it does not relate to the Total Fertility Rate but rather to the success rate of deliveries.

The placenta is developed from which part of the trophoblast?
- A. Chorionic Frondosum
- B. Anchoring Villi
- C. Chorionic Laeve
- D. Body Stalk
Correct Answer: A
Rationale: The correct answer is A: Chorionic Frondosum. The placenta is developed from the chorionic frondosum part of the trophoblast. This structure gives rise to the fetal part of the placenta. Choices B, C, and D are incorrect. Anchoring Villi are projections from the chorionic plate that attach the placenta to the uterine wall. Chorionic Laeve refers to the smooth chorion that covers the fetal surface of the placenta. The Body Stalk is a structure that connects the early embryo to the trophoblastic pole of the blastocyst.
During the menstrual cycle, which hormone maintains the corpus luteum?
- A. Luteinizing hormone
- B. Follicle-stimulating hormone
- C. Progesterone
- D. Relaxin
Correct Answer: A
Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.
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.
