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. During fertilization, the portion of the decidua covering the blastocyst is called:

• A. Decidua basalis
• B. Decidua Vera
• C. Decidua parietalis
• D. Decidua capsularis

Correct answer: D

Rationale: During fertilization, the decidua capsularis is the specific portion of the decidua that covers the blastocyst, providing protection and support. Decidua basalis refers to the part of the decidua located at the site of implantation on the maternal side. Decidua vera is the remainder of the decidua lining the uterus. Decidua parietalis is the portion of the decidua that lines the rest of the uterine cavity, except for the site of implantation. Therefore, in the context of fertilization, the decidua capsularis is the correct answer.

3. 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.

4. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.

5. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

• A. Menorrhagia
• B. Metrorrhagia
• C. Polymenorrhoea
• D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.
