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. The upper folds of the labia minora surround the clitoris and unite to form the:

• A. Frenulum
• B. Prepuce
• C. Fourchette
• D. Vestibule

Correct answer: B

Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.

3. In 1989, the national population policy was formally launched targeting:

• A. Reducing population growth
• B. Making family planning services available
• C. Making services accessible and affordable to all eligible users
• D. All of the above

Correct answer: D

Rationale: The correct answer is D because the national population policy launched in 1989 aimed at reducing population growth by making family planning services available, accessible, and affordable to all eligible users. Choice A is incorrect as it does not encompass the full scope of the policy objectives. Choice B is also incomplete as it focuses solely on availability without considering accessibility and affordability. Choice C is partially correct but lacks the comprehensive approach of the national population policy.

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. What is the leading cause of maternal mortality?

• A. Pre-eclampsia
• B. Haemorrhage
• C. Sepsis
• D. Obstructed labour

Correct answer: B

Rationale: The correct answer is B: Haemorrhage. Haemorrhage is a leading cause of maternal mortality due to excessive bleeding during childbirth. While conditions like pre-eclampsia, sepsis, and obstructed labor can also be serious complications during pregnancy and childbirth, they are not the primary cause of maternal mortality worldwide.
