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.'

Which of the following structures is responsible for the production of sperm?
- A. Epididymis
- B. Seminal vesicles
- C. Testes
- D. Prostate gland
Correct Answer: C
Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.
What is the purpose of Hysterosalpingo-contrast Sonography?
- A. Check a woman's tubes and is done with an X-ray and dye test called a hysterosalpingogram
- B. Detect Human Chorionic Gonadotrophic hormone (HCG) in urine or whole blood.
- C. Diagnose ovarian cancer using MRI technology.
- D. Detect cancer cells in the cervix.
Correct Answer: A
Rationale: Hysterosalpingo-contrast Sonography is a test used to check a woman's fallopian tubes with an X-ray and dye test called a hysterosalpingogram. This test is specifically designed to evaluate the patency of the fallopian tubes and the uterine cavity. Choices B, C, and D are incorrect as they do not align with the purpose of Hysterosalpingo-contrast Sonography.
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.
Which of the following is not a complication of menopause?
- A. Fractures
- B. Alzheimer's disease
- C. Congestive heart failure
- D. Painful intercourse
Correct Answer: C
Rationale: Congestive heart failure is not typically associated with menopause. Menopause is linked to an increased risk of fractures due to bone density loss, a higher risk of Alzheimer's disease due to hormonal changes, and painful intercourse due to vaginal dryness and thinning of tissues. While cardiovascular health can be affected by menopause, congestive heart failure is not a direct complication associated with menopause.
In missed abortion, what will the woman often experience?
- A. Severe cramping and lower abdominal pains
- B. Brownish vaginal discharge
- C. Profuse per vagina bleeding
- D. Open cervical OS
Correct Answer: B
Rationale: In missed abortion, the woman often experiences brownish vaginal discharge. This is known as a symptom of missed abortion. Severe cramping and lower abdominal pains (Choice A) are more characteristic of an incomplete abortion, where not all pregnancy tissue is expelled. Profuse per vagina bleeding (Choice C) is more commonly associated with a complete abortion. Open cervical OS (Choice D) is a physical finding and not a typical symptom reported by the woman in missed abortion.
