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. Which of the following is a common presentation in women with polycystic ovarian syndrome?

• A. Oligomenorrhea, obesity, and hirsutism
• B. Amenorrhea, generalized hair loss, and weight gain
• C. Repeated ectopic pregnancies and chronic pelvic pain
• D. Fatigue, body aches, and menorrhagia

Correct answer: A

Rationale: The correct answer is A: Oligomenorrhea, obesity, and hirsutism. Polycystic ovarian syndrome (PCOS) commonly presents with irregular periods (oligomenorrhea), obesity, and increased hair growth (hirsutism) due to hormonal imbalances. Choice B is incorrect as amenorrhea (absence of periods), generalized hair loss, and weight gain are not typical features of PCOS. Choice C is incorrect as repeated ectopic pregnancies and chronic pelvic pain are not characteristic of PCOS. Choice D is incorrect as fatigue, body aches, and menorrhagia (excessive menstrual bleeding) are not primary symptoms seen in PCOS.

3. Which of the following is an example of a viviparous animal?

• A. Goat
• B. Duck
• C. Crocodile
• D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

4. Through which arteries does the blood supply to the external genitalia primarily occur?

• A. Femoral arteries
• B. Inguinal arteries
• C. Pudendal arteries
• D. Internal iliac arteries

Correct answer: C

Rationale: The correct answer is C: Pudendal arteries. The pudendal arteries are responsible for supplying blood to the external genitalia. These arteries specifically provide blood flow to the perineum, including the external genitalia. Choice A, Femoral arteries, are not primarily responsible for supplying blood to the external genitalia. Choice B, Inguinal arteries, do not supply blood directly to the external genitalia. Choice D, Internal iliac arteries, are not the main suppliers of blood to the external genitalia.

5. What does reproductive health refer to?

• A. Healthy baby
• B. Frequent coitus
• C. Healthy reproductive organs and functions
• D. Longer lifetime

Correct answer: C

Rationale: Reproductive health refers to the overall well-being of the reproductive system, including both the organs and their functions. It encompasses the ability to have a satisfying and safe sex life, the capability to reproduce, and the absence of reproductive problems. Choice A is incorrect because reproductive health is not solely about having a healthy baby but also includes the health of the individual. Choice B is incorrect as it focuses only on sexual activity frequency rather than the holistic well-being of the reproductive system. Choice D is incorrect because a longer lifetime does not specifically relate to reproductive health.
