1. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

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. At 34-40 weeks of pregnancy, the breast changes include:

• A. Nipples become prominent and mobile.
• B. Colostrum can be expressed.
• C. Breasts become tender.
• D. Montgomery's tubercles are prominent.

Correct answer: D

Rationale: During the 34-40 weeks of pregnancy, Montgomery's tubercles become prominent. These are sebaceous glands on the areola, not the nipples. Choice A is incorrect as it describes the changes in nipples, not Montgomery's tubercles. Choice B is incorrect as colostrum production usually starts around the 16th week. Choice C is incorrect as breast tenderness is more common in early pregnancy due to hormonal changes.

4. The Gravindex test is used to detect Human Chorionic Gonadotrophic hormone (HCG) in:

• A. Urine or whole blood
• B. Amniotic fluid
• C. Saliva
• D. Cervical mucus

Correct answer: A

Rationale: The correct answer is A: Urine or whole blood. The Gravindex test is designed to detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood samples. HCG is a hormone produced during pregnancy, and its presence in urine or blood can indicate pregnancy. Choices B, C, and D are incorrect as the Gravindex test is not intended to detect HCG in amniotic fluid, saliva, or cervical mucus. These bodily fluids are not typically used for pregnancy testing purposes.

5. 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.
