During which phase of the menstrual cycle does the Graafian follicle rupture?
- A. Regenerative
- B. Menstruation
- C. Ovulation
- D. Proliferative
Correct Answer: C
Rationale: The correct answer is C: Ovulation. The Graafian follicle ruptures during the ovulation phase, releasing the mature egg from the ovary. This process marks the midpoint of the menstrual cycle. Choice A, Regenerative, is incorrect as it does not correspond to a specific phase of the menstrual cycle. Choice B, Menstruation, is incorrect because menstruation is the shedding of the uterine lining and occurs after ovulation if fertilization does not occur. Choice D, Proliferative, is incorrect as it refers to the phase in which the uterine lining thickens in preparation for a potential embryo implantation, which happens after ovulation.

At what age are women likely to enter menopause?
- A. 35 - 40 years
- B. 40 - 45 years
- C. 45 - 50 years
- D. 25 - 30 years
Correct Answer: C
Rationale: Women generally enter menopause between the ages of 45 - 50 years. During this stage, women experience a decline in estrogen production, leading to the cessation of menstrual cycles. Choices A, B, and D are incorrect as they do not fall within the typical age range for menopause onset. Menopause typically occurs later in life, around the age of 45 to 50 years, although individual variations exist.
What are the external organs of the female collectively known as?
- A. Vulva
- B. Frenulum
- C. Mons veneris
- D. Vestibule
Correct Answer: A
Rationale: The correct answer is A: Vulva. The external organs of the female reproductive system, including the labia majora, labia minora, clitoris, vaginal opening, and Bartholin's glands, are collectively known as the vulva.
Choice B, Frenulum, is incorrect as it refers to a small band of tissue. Choice C, Mons veneris, specifically refers to the rounded mass of fatty tissue located over the pubic bone, not all external female reproductive organs. Choice D, Vestibule, is incorrect as it is the space enclosed by the labia minora that includes the vaginal and urethral openings, not all external female reproductive organs.
Where does the ovum receive the sperm?
- A. Animal pole
- B. Vegetal pole
- C. Zona pellucida
- D. None of the above
Correct Answer: C
Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.
The _________ is a temporary organ that connects a mammalian mother to its foetus.
- A. Placenta
- B. Chorion
- C. Endometrium
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Placenta. The placenta is a temporary organ that connects a mammalian mother to its foetus. It plays a crucial role in facilitating the exchange of nutrients, oxygen, and waste between the mother and the developing baby. Choice B, Chorion, is incorrect as it is a part of the fetal membrane but not the organ that connects the mother to the fetus. Choice C, Endometrium, is incorrect as it is the lining of the uterus where implantation occurs but is not the organ responsible for connecting the mother to the fetus. Choice D, None of the above, is incorrect as the placenta specifically fits the description provided in the question.
A client 12 weeks pregnant comes to the emergency department with abdominal cramping and moderate vaginal bleeding. Speculum examination reveals 2 to 3 cm cervical dilation. The nurse would document these findings as which of the following?
- A. Threatened abortion
- B. Inevitable abortion
- C. Complete abortion
- D. Missed abortion
Correct Answer: B
Rationale: The nurse would document these findings as an inevitable abortion. Inevitable abortion is characterized by cervical dilation with or without rupture of membranes and is associated with moderate to heavy vaginal bleeding. 'Threatened abortion' (choice A) refers to vaginal bleeding with a closed cervical os and no tissue passage. 'Complete abortion' (choice C) involves the passage of all products of conception. 'Missed abortion' (choice D) is the retention of a failed intrauterine pregnancy for an extended period without symptoms.
