Inevitable abortion occurs when:
- A. The ovum dies in utero and the decidua capsularis remains intact.
- B. The cervix is open, and the products of conception are about to be expelled.
- C. The products of conception are expelled before the 20th week of gestation.
- D. The fetus dies and is expelled in the first trimester.
Correct Answer: B
Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.

When does a broad ligament haematoma occur?
- A. Rupture occurs in the mesenteric border of the tube.
- B. Rupture occurs in the ovarian ligament.
- C. Rupture occurs in the broad ligament.
- D. Rupture occurs in the uterine wall.
Correct Answer: A
Rationale: A broad ligament hematoma occurs when there is a rupture in the mesenteric border of the tube. This typically happens due to trauma or other underlying conditions. Choices B, C, and D are incorrect because a broad ligament hematoma specifically involves a rupture in the mesenteric border of the tube, not the ovarian ligament, broad ligament, or uterine wall.
The upper folds of the labia minora surround the clitoris and unite to form the:
- A. Frenulum
- B. Prepuce
- C. Fourchette
- D. Vestibule
Correct Answer: B
Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.
After fertilization, cell division occurs through a process of:
- A. Binary fission
- B. Meiosis
- C. Budding
- D. Mitosis
Correct Answer: D
Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.
What type of epithelium lines the fallopian tubes?
- A. Ciliated epithelium.
- B. Stratified epithelium.
- C. Columnar epithelium.
- D. Endometrium.
Correct Answer: A
Rationale: The correct answer is A: Ciliated epithelium. The fallopian tubes are lined with ciliated epithelium, which helps to move the egg from the ovary to the uterus. Choice B, Stratified epithelium, is incorrect because the fallopian tubes are lined with a single layer of cells. Choice C, Columnar epithelium, is incorrect as it does not accurately describe the lining of the fallopian tubes. Choice D, Endometrium, is incorrect because the endometrium is the inner lining of the uterus, not the fallopian tubes.
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.
