1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. 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.

3. Which of the following is NOT a phase of the menstrual cycle?

• A. Follicular phase
• B. Ovulatory phase
• C. Luteal phase
• D. Secretory phase

Correct answer: D

Rationale: The secretory phase is not considered a distinct phase of the menstrual cycle; it is actually part of the luteal phase. During the luteal phase, the endometrium thickens due to progesterone secretion, preparing for implantation. The follicular phase is characterized by follicle development, leading to ovulation. The ovulatory phase is when the mature egg is released from the ovary. Therefore, the secretory phase is the correct answer as it is not a standalone phase but a part of the luteal phase.

4. What is dysmenorrhoea?

• A. Heavy menstruation
• B. Light menstruation
• C. Painful menstruation
• D. Infrequent menstruation

Correct answer: C

Rationale: Dysmenorrhoea is the medical term for painful menstruation. It is characterized by cramp-like abdominal pain that occurs just before or during menstruation. Choice A, heavy menstruation, is referred to as menorrhagia. Choice B, light menstruation, is not a term used to describe a specific menstrual condition. Choice D, infrequent menstruation, is known as oligomenorrhea, not dysmenorrhoea.

5. The products of conception are retained in which of the following?

• A. Complete abortions
• B. Incomplete abortions
• C. Threatened abortion
• D. Mixed abortion

Correct answer: B

Rationale: In incomplete abortions, the products of conception are retained. In a complete abortion, all the products of conception are expelled from the uterus. Threatened abortion refers to a situation where there is vaginal bleeding but the cervix remains closed, and it does not necessarily involve retention of products of conception. Mixed abortion is not a recognized medical term related to retained products of conception.
