Which one of the following is not a stage in the ovarian cycle of the menstrual cycle?
- A. Recruitment of Graafian follicle
- B. Selection of dominant follicle
- C. Luteal phase
- D. Formation of corpus luteum
Correct Answer: A
Rationale: The correct answer is A. The recruitment of the Graafian follicle is indeed a stage in the ovarian cycle. During the ovarian cycle, the primary follicles are recruited to develop further, leading to the formation of the Graafian follicle. The selection of the dominant follicle, luteal phase, and formation of the corpus luteum are other essential stages in the ovarian cycle. Therefore, option A is not correct as it is a crucial phase in the process of ovulation and fertilization.

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 is the most common symptom in all clinical types of abortion EXCEPT:
- A. Lower abdominal pain
- B. Per vaginal bleeding
- C. Show
- D. Backache
Correct Answer: C
Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.
Which of the following is the description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age?
- A. Bright red mucosa surrounding the cervical os, in turn surrounded by smooth, pink mucosa
- B. Pink mucosa with multiple small, fluid-filled protrusions
- C. Pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os
- D. Smooth, pink mucosa and a small, fleshy protrusion through the cervical os
Correct Answer: C
Rationale: The correct description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age is pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os. This appearance is characteristic of a healthy cervix. Choice A is incorrect as a bright red mucosa is not normal. Choice B is incorrect as multiple small, fluid-filled protrusions suggest a different condition. Choice D is incorrect as a fleshy protrusion through the cervical os is abnormal.
Discuss the anatomical/physiological changes in pregnancy related to the breasts.
- A. Breast tenderness increases, circulatory supply to the breasts increases, leading to breast enlargement, and colostrum secretion occurs.
- B. Breast tenderness decreases, and there is no significant change in breast size.
- C. Breast changes include decreased tenderness and reduced circulatory supply.
- D. Breasts do not undergo significant changes during pregnancy.
Correct Answer: A
Rationale: During pregnancy, the breasts undergo significant anatomical and physiological changes. These changes include increased breast tenderness, an increase in circulatory supply to the breasts, resulting in breast enlargement, and the secretion of colostrum. Choice B is incorrect as breast tenderness actually increases during pregnancy. Choice C is incorrect as the circulatory supply to the breasts increases rather than reduces. Choice D is incorrect as breasts do undergo notable changes during pregnancy.
How many arteries are there in an umbilical cord?
- A. Three
- B. One
- C. Two
- D. Four
Correct Answer: C
Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.
