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. What does Integrated Reproductive Health entail?

• A. Women of childbearing age
• B. Women and under-five children only
• C. Men, women, adolescents, youth, and children
• D. Pregnant women only

Correct answer: C

Rationale: Integrated Reproductive Health involves providing services that cater to a wide range of demographics, including men, women, adolescents, youth, and children. This comprehensive approach ensures that reproductive health needs are addressed across different age groups and genders. Choices A, B, and D are too restrictive and do not encompass the full scope of Integrated Reproductive Health services.

3. What is the term used to describe the gestational sac surrounded by a blood clot and retained in the tube?

• A. A carneous mole.
• B. A hydatidiform mole.
• C. A vesicular mole.
• D. A chorionic mole.

Correct answer: A

Rationale: The correct answer is A: a carneous mole. A carneous mole occurs when a gestational sac is surrounded by a blood clot and retained in the tube. Choice B, a hydatidiform mole, is incorrect as it refers to an abnormal pregnancy characterized by the presence of hydropic chorionic villi. Choice C, a vesicular mole, is also incorrect as it is another term for a complete hydatidiform mole. Choice D, a chorionic mole, is not a recognized medical term and is therefore incorrect.

4. Which technique is used to detect HIV/AIDS?

• A. Northern blot and ELISA
• B. Immunoblot and ELISA
• C. Western blot and ELISA
• D. Southern blot and ELISA

Correct answer: C

Rationale: The correct answer is C: Western blot and ELISA. Western blot and ELISA are commonly used techniques in the detection of HIV/AIDS. Western blot is used to confirm the presence of HIV antibodies in a patient's blood after an initial positive ELISA test. Northern blotting is a technique used for RNA analysis, not for detecting HIV/AIDS (Choice A). Immunoblotting is another term for Western blotting, so Choice B is incorrect. Southern blotting is used for DNA analysis, not for detecting HIV/AIDS (Choice D).

5. Which hormone is primarily responsible for the development of female secondary sexual characteristics?

• A. Progesterone
• B. Testosterone
• C. Estrogen
• D. Oxytocin

Correct answer: C

Rationale: Estrogen is primarily responsible for the development of female secondary sexual characteristics. Progesterone, while important in the menstrual cycle and pregnancy, is not primarily responsible for secondary sexual characteristics. Testosterone is the primary male sex hormone. Oxytocin is involved in labor, lactation, and social bonding, but not in the development of female secondary sexual characteristics.
