Reproductive System Exam Questions

1. At 3-4 weeks of pregnancy, the breast changes include:

A. Darkening of the nipple.
B. Prickling, tingling sensation.
C. Breast becomes tender.
D. Colostrum can be expressed.

Correct answer: C

Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.

2. What is the role of the prolactin hormone?

A. Stimulates the development of milk-producing tissue.
B. Stimulates milk storage.
C. Stimulates milk production.
D. Stimulates milk ejection.

Correct answer: C

Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

3. What is the role of the corpus luteum during the menstrual cycle?

A. The corpus luteum produces estrogen to maintain the endometrium.
B. The corpus luteum produces progesterone to maintain the endometrium.
C. The corpus luteum produces testosterone to inhibit ovulation.
D. The corpus luteum has no significant role during the menstrual cycle.

Correct answer: B

Rationale: The correct answer is B: The corpus luteum produces progesterone to maintain the endometrium during the menstrual cycle. This hormone helps prepare the uterine lining for implantation in case fertilization occurs. Choice A is incorrect because estrogen is mainly produced by the developing follicles in the ovaries. Choice C is incorrect as testosterone is produced in smaller amounts by the ovaries and adrenal glands but does not play a significant role in maintaining the endometrium. Choice D is incorrect as the corpus luteum plays a crucial role in producing progesterone to support the endometrium.

4. 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.

5. Which of the following data should not be included in the identification data of gynecological history?

A. Parity
B. Lost normal menstrual period
C. EDD (Expected date of delivery)
D. Last delivery

Correct answer: C

Rationale: The correct answer is C: EDD (Expected date of delivery). In a gynecological history, EDD is not typically included as it pertains more to obstetric history. Parity, lost normal menstrual period, and last delivery are important components of gynecological history. Parity refers to the number of times a woman has given birth to a fetus past 20 weeks' gestation. Lost normal menstrual period can provide insight into potential gynecological issues, while last delivery details the most recent childbirth experience. Therefore, EDD is the outlier in this context.
