1. 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).

2. _______ 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.

3. What is a characteristic of threatening abortion?

• A. Os open.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

4. Treatment for condylomata acuminata includes the following EXCEPT:

• A. Vulvectomy
• B. Podophyllin application
• C. Laser therapy
• D. Electrocautery

Correct answer: A

Rationale: The correct answer is A. Vulvectomy is not a standard treatment for condylomata acuminata, which are genital warts caused by human papillomavirus (HPV). Surgical removal of the vulva (vulvectomy) is an extreme measure and not typically indicated for treating this condition. Choices B, C, and D are valid treatments for condylomata acuminata. Podophyllin application, laser therapy, and electrocautery are commonly used to remove or destroy genital warts caused by HPV. These treatments aim to eliminate the visible warts and clear the infection.

5. What phase corresponds with the luteal phase?

• A. Menstrual phase
• B. Follicular phase
• C. Secretory phase
• D. Menstrual phase

Correct answer: C

Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.
