1. Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system

• A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
• B. The heart is displaced downward and to the right, and blood pressure increases.
• C. The cardiovascular system remains unchanged during pregnancy.
• D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.

Correct answer: A

Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.

2. Through which arteries does the blood supply to the external genitalia primarily occur?

• A. Femoral arteries
• B. Inguinal arteries
• C. Pudendal arteries
• D. Internal iliac arteries

Correct answer: C

Rationale: The correct answer is C: Pudendal arteries. The pudendal arteries are responsible for supplying blood to the external genitalia. These arteries specifically provide blood flow to the perineum, including the external genitalia. Choice A, Femoral arteries, are not primarily responsible for supplying blood to the external genitalia. Choice B, Inguinal arteries, do not supply blood directly to the external genitalia. Choice D, Internal iliac arteries, are not the main suppliers of blood to the external genitalia.

3. Which of the following is an example of an oviparous animal?

• A. Pigeon
• B. Elephant
• C. Sheep
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.

4. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

• A. Menorrhagia
• B. Metrorrhagia
• C. Polymenorrhoea
• D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.

5. 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.
