Reproductive System Exam Questions

1. 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.

2. 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).

3. What is the role of the progesterone hormone?

A. Stimulates the development of the nipple and duct system in the breast.
B. Stimulates the storage of milk.
C. Stimulates the secretion of relaxin.
D. Stimulates the development of glandular tissue in the breast.

Correct answer: A

Rationale: The correct answer is A. Progesterone hormone's role includes stimulating the development of the nipple and duct system in the breast. This hormone is crucial for preparing the breast for potential pregnancy by promoting the growth of structures necessary for milk production. Choices B, C, and D are incorrect because progesterone primarily focuses on preparing the breast for lactation rather than directly stimulating milk storage, relaxin secretion, or glandular tissue development.

4. Basal body temperature rise of _____ is seen in the luteal phase due to the thermogenic effects of a metabolite of progesterone in a normal cycle:

A. 0.1-0.5
B. 0.2-0.5
C. 1.0-2.0
D. 1.5-2.0

Correct answer: B

Rationale: A basal body temperature rise of 0.2-0.5 degrees Celsius is typically seen in the luteal phase of the menstrual cycle due to the thermogenic effects of a metabolite of progesterone. This temperature rise helps to indicate ovulation has occurred. Choices A, C, and D are incorrect as they do not reflect the usual range of temperature increase observed during the luteal phase. A rise of 0.1-0.5 degrees Celsius is too narrow (eliminating choice A), while ranges of 1.0-2.0 and 1.5-2.0 degrees Celsius are too high and not consistent with the expected basal body temperature changes during the menstrual cycle.

5. Mrs. Banda is a patient at the ward with complaints of light menstrual periods, which occur at intervals greater than 35 days. Your diagnosis will be:

A. Oligomenorrhea
B. Menorrhagia
C. Metrorrhagia
D. Polymenorrhea

Correct answer: A

Rationale: The correct diagnosis for Mrs. Banda's condition is Oligomenorrhea. Oligomenorrhea is characterized by light menstrual periods occurring at intervals longer than 35 days. Choice B, Menorrhagia, refers to abnormally heavy menstrual bleeding. Choice C, Metrorrhagia, is bleeding at irregular intervals, and Choice D, Polymenorrhea, involves menstrual cycles occurring at intervals shorter than 21 days.
