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 the most important factor in ensuring accessibility in reproductive health services?

• A. Ensuring that primary health care (PHC) services are available within a reasonable distance.
• B. Requiring patients to access multiple services to get the care they need.
• C. Providing reproductive health services only to those who can afford it.
• D. Providing health services only in urban areas.

Correct answer: A

Rationale: The correct answer is A: Ensuring that primary health care (PHC) services are available within a reasonable distance. Accessibility in reproductive health services is crucial for ensuring that individuals can easily access the care they need. Option B is incorrect because requiring patients to access multiple services can create barriers to care. Option C is incorrect as accessibility should not be limited based on financial means. Option D is incorrect because healthcare services should be available in both urban and rural areas to reach a wider population.

3. What is the definition of incomplete abortion?

• A. Part of the products of conception, especially the fetus, is expelled while the placenta and membranes are retained.
• B. All products of conception are expelled, and there is minimal per vaginal bleeding.
• C. The cervix is closed, and the products of conception remain in the uterus.
• D. The cervix dilates, and the products of conception are expelled.

Correct answer: A

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.

4. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

5. 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.
