1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. Which hormone is released from the testes?

• A. Progesterone
• B. Vasopressin
• C. Testosterone
• D. None of the above

Correct answer: C

Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.

3. What type of epithelium lines the fallopian tubes?

• A. Ciliated epithelium.
• B. Stratified epithelium.
• C. Columnar epithelium.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.

4. 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.

5. What prompted Zambia to implement family planning services?

• A. The nation started to experience the effects of rapid population growth on the economy and individual welfare.
• B. Donors provided free family planning pills.
• C. Mothers were delivering twice a year.
• D. There were too many abortions.

Correct answer: A

Rationale: The correct answer is A. Rapid population growth's impact on the economy and individual welfare prompted Zambia to implement family planning services. This is because a rapidly growing population can strain resources, lead to unemployment, poverty, and inadequate access to healthcare. Choice B is incorrect because the provision of free family planning pills by donors may have been a subsequent intervention rather than the initial reason for implementing family planning services. Choice C is irrelevant as the frequency of deliveries by mothers does not directly relate to the implementation of family planning services. Choice D is also incorrect as high abortion rates may be a consequence of inadequate family planning services rather than the reason for their implementation.
