Reproductive System Exam Quizlet
1. Inevitable abortion is characterized by:
- A. Heavy bleeding.
- B. Open os.
- C. Severe cramping.
- D. Light bleeding.
Correct answer: B
Rationale: Inevitable abortion is characterized by an open os. This condition is associated with heavy bleeding. While severe cramping can be present in inevitable abortion, the key characteristic is the open os, making choice B the correct answer. Choices A and D are incorrect because they do not specifically describe the defining feature of inevitable abortion, which is the open os.
2. Causes of metrorrhagia include:
- A. Cervical carcinoma
- B. Uterine polyp
- C. Cervical endometriosis
- D. Infections like Chlamydia
Correct answer: A
Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.
3. 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).
4. During menopause, what do ovaries stop producing?
- A. Progesterone and Estrogen
- B. Prolactin
- C. Human chorionic gonadotropin
- D. Oxytocin
Correct answer: A
Rationale: During menopause, the ovaries stop producing progesterone and estrogen. Progesterone and estrogen are hormones essential for the menstrual cycle and reproductive functions. Prolactin is a hormone responsible for milk production in the breasts and is not primarily produced by the ovaries. Human chorionic gonadotropin (hCG) is produced during pregnancy to support the production of progesterone and estrogen. Oxytocin is a hormone involved in labor and breastfeeding, not primarily produced by the ovaries.
5. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:
- A. Zygote
- B. Blastomere
- C. Morula
- D. Blastocyst
Correct answer: C
Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'
