1. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

2. What is the role of relaxin hormone?

• A. Relaxation of the symphysis pubis.
• B. Stimulation of milk production.
• C. Stimulating the development of the nipple and duct system in the breast.
• D. None of the above.

Correct answer: A

Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.

3. What is the most common cause of abortion in Zambia?

• A. Malaria.
• B. Tuberculosis.
• C. HIV.
• D. Ascariasis.

Correct answer: A

Rationale: The correct answer is A: Malaria. Malaria is a prevalent cause of abortion in Zambia due to its impact on maternal health. Malaria infection during pregnancy can lead to severe complications, including miscarriage. Choices B, C, and D are incorrect because while Tuberculosis, HIV, and Ascariasis are significant health issues, they are not the commonest cause of abortion in Zambia as Malaria.

4. During fertilization, the portion of the decidua covering the blastocyst is called:

• A. Decidua basalis
• B. Decidua Vera
• C. Decidua parietalis
• D. Decidua capsularis

Correct answer: D

Rationale: During fertilization, the decidua capsularis is the specific portion of the decidua that covers the blastocyst, providing protection and support. Decidua basalis refers to the part of the decidua located at the site of implantation on the maternal side. Decidua vera is the remainder of the decidua lining the uterus. Decidua parietalis is the portion of the decidua that lines the rest of the uterine cavity, except for the site of implantation. Therefore, in the context of fertilization, the decidua capsularis is the correct answer.

5. Cryptorchidism is a condition where _________.

• A. One or both testes are not developed
• B. One or both testes fail to descend into the scrotum
• C. One or both testes are not formed
• D. None of the above

Correct answer: B

Rationale: Cryptorchidism is a condition where one or both testes fail to descend into the scrotum. This means that the testes do not properly move from the abdomen into the scrotum during fetal development. Choice A is incorrect because the issue is not about development but descent. Choice C is incorrect as it implies that the testes were never formed, which is not the case in cryptorchidism. Choice D is incorrect as cryptorchidism does involve the testes but rather their descent into the scrotum.
