Reproductive Health Exam

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. What is the role of the prolactin hormone?

A. Stimulates the development of milk-producing tissue.
B. Stimulates milk storage.
C. Stimulates milk production.
D. Stimulates milk ejection.

Correct answer: C

Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

3. The menstrual disorder in which there is an absence or suppression of the normal menstrual period is called:

A. Dysmenorrhoea
B. Polymenorrhoea
C. Menorrhagia
D. Amenorrhoea

Correct answer: D

Rationale: Amenorrhoea is the correct term for the absence or suppression of the menstrual period. Dysmenorrhoea refers to painful menstruation, Polymenorrhoea is characterized by frequent, short menstrual cycles, and Menorrhagia is excessive menstrual bleeding. Therefore, 'Amenorrhoea' is the most appropriate term for the described menstrual disorder.

4. 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.

5. 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.
