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. What is one of the major issues affecting adolescents in terms of sexual and reproductive health?

• A. Limited access to contraceptives and family planning
• B. Equal representation in decision-making
• C. Decreased need for sexual education
• D. Equal opportunities for career growth

Correct answer: A

Rationale: Limited access to contraceptives and family planning is indeed a major issue affecting adolescents in terms of sexual and reproductive health. This lack of access can lead to unintended pregnancies, sexually transmitted infections, and limited reproductive choices. Choice B, equal representation in decision-making, although important, is not directly related to sexual and reproductive health issues faced by adolescents. Choice C, decreased need for sexual education, is incorrect as proper sexual education is crucial in promoting healthy behaviors and preventing risks. Choice D, equal opportunities for career growth, is also unrelated to the specific issues surrounding sexual and reproductive health in adolescents.

3. What is the function of luteinizing hormone?

• A. Maintains the corpus luteum
• B. Ripens the Graafian follicle
• C. Prepares the breasts for lactation
• D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

4. Where does the ovum receive the sperm?

• A. Animal pole
• B. Vegetal pole
• C. Zona pellucida
• D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

5. Total Fertility Rate is at 6.2 births per woman in Zambia. This implies that:

• A. Zambian women will give birth to 6.2 children on average during their childbearing years.
• B. 6.2% of the time she will be pregnant during her childbearing years.
• C. 6.2% of her deliveries will not be successful.
• D. 6.2% of women will require medical intervention to become pregnant.

Correct answer: A

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. Choice D is incorrect as it introduces the idea of medical intervention, which is not directly related to the Total Fertility Rate.
