Reproductive Health Exam

1. At 16 weeks of pregnancy, the breast changes include:

A. Montgomery's tubercles are prominent.
B. Darkening of the nipple.
C. Prickling, tingling sensation.
D. Colostrum can be expressed.

Correct answer: C

Rationale: At 16 weeks of pregnancy, the sensation of prickling and tingling in the breasts is common due to hormonal changes. Montgomery's tubercles becoming prominent is more characteristic of early pregnancy, typically around the first trimester. Darkening of the nipple, known as areola darkening, can occur but is more commonly observed later in pregnancy. The expression of colostrum, the first milk produced by the mammary glands, usually happens closer to the end of pregnancy or after childbirth, not typically at 16 weeks.

2. 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.

3. What is a Carneous Mole defined as?

A. Occurs when fluids drain from the blood mole, leaving a fresh firm mass.
B. Occurs when the ovum dies and is expelled.
C. Occurs when the fetus dies, and the membranes rupture.
D. Occurs when the fetus survives after a failed abortion attempt.

Correct answer: A

Rationale: A Carneous Mole is defined as when fluids drain from the blood mole, leaving a fresh firm mass. This process leads to the formation of a solid mass resembling tissue. Choice B is incorrect as it describes a different concept known as a missed abortion, where the ovum dies and is expelled. Choice C is incorrect as it describes a situation related to fetal demise and membrane rupture, not specifically the formation of a Carneous Mole. Choice D is incorrect as it refers to a scenario where the fetus survives after a failed abortion attempt, which is distinct from the definition of a Carneous Mole.

4. Septic abortion is characterized by:

A. Backache.
B. Os open.
C. Heavy bleeding.
D. Maternal pyrexia.

Correct answer: D

Rationale: Septic abortion is characterized by maternal pyrexia. Maternal pyrexia, or fever, is a hallmark sign of septic abortion due to infection. Backache and heavy bleeding can be present in abortion but are not specific to septic abortion. 'Os open' does not directly characterize septic abortion.

5. What is the function of luteinizing hormone?

A. Maintains the corpus luteum
B. Ripens the Graafian follicle
C. Prepares the breasts for lactation
D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.
