Which contraceptive option suppresses sperm motility and inhibits the implantation of the blastocyst?
- A. Copper-T
- B. Diaphragm
- C. Contraceptive pills
- D. Condom
Correct Answer: A
Rationale: The correct answer is A, Copper-T. Copper-T is an intrauterine device that releases copper ions, which suppress sperm motility and inhibit the implantation of the blastocyst. This method mainly works by preventing fertilization and, if fertilization occurs, by making the endometrium less receptive to implantation. Choices B, C, and D are incorrect. The diaphragm is a barrier method that prevents sperm from reaching the cervix; contraceptive pills mainly work by suppressing ovulation and altering cervical mucus to prevent sperm from reaching the egg; condoms are barrier methods that prevent sperm from entering the vagina.

At what point is a fetus considered viable?
- A. 26 weeks
- B. 28 weeks
- C. 37 weeks
- D. 12 weeks
Correct Answer: C
Rationale: A fetus is considered viable after 37 weeks of gestation. At this stage, the fetus has a higher chance of surviving outside the womb with medical support. Choice A (26 weeks), Choice B (28 weeks), and Choice D (12 weeks) are incorrect because a fetus is not typically considered viable at those earlier gestational ages.
In order to provide services effectively and in the best interests of the whole family:
- A. The wife's relatives need to be contacted
- B. It's important to seek the services of a traditional healer
- C. Health providers need to be aware of the roles and decision-making process within the family
- D. Health providers need to conduct door-to-door sensitization on health matters
Correct Answer: C
Rationale: The correct answer is C: 'Health providers need to be aware of the roles and decision-making process within the family.' To provide services effectively, health providers must understand the dynamics within a family, including who makes decisions and how roles are distributed. This knowledge helps them tailor their services to meet the needs and preferences of the whole family. Choices A and B are incorrect because contacting the wife's relatives or seeking the services of a traditional healer may not necessarily align with providing effective services based on family dynamics. Choice D is also incorrect as door-to-door sensitization may not directly address the internal dynamics of a family.

Which hormone is primarily responsible for the development of female secondary sexual characteristics?
- A. Progesterone
- B. Testosterone
- C. Estrogen
- D. Oxytocin
Correct Answer: C
Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
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.
