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. Which phase of the menstrual cycle is variable?

• A. Ovulatory
• B. Regenerative
• C. Secretory
• D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

3. Discuss the anatomical/physiological changes in pregnancy related to the breasts.

• A. Breast tenderness increases, circulatory supply to the breasts increases, leading to breast enlargement, and colostrum secretion occurs.
• B. Breast tenderness decreases, and there is no significant change in breast size.
• C. Breast changes include decreased tenderness and reduced circulatory supply.
• D. Breasts do not undergo significant changes during pregnancy.

Correct answer: A

Rationale: During pregnancy, the breasts undergo significant anatomical and physiological changes. These changes include increased breast tenderness, an increase in circulatory supply to the breasts, resulting in breast enlargement, and the secretion of colostrum. Choice B is incorrect as breast tenderness actually increases during pregnancy. Choice C is incorrect as the circulatory supply to the breasts increases rather than reduces. Choice D is incorrect as breasts do undergo notable changes during pregnancy.

4. Where does fertilization normally occur?

• A. Ampulla
• B. Interstitial portion
• C. Isthmus
• D. Infundibulum

Correct answer: A

Rationale: Fertilization typically occurs in the ampulla of the fallopian tube. The ampulla provides the ideal environment for fertilization due to the presence of cilia that help transport the egg and sperm, as well as the nourishing fluid within this region. The interstitial portion, isthmus, and infundibulum of the fallopian tube are not the primary sites for fertilization. The interstitial portion connects the fallopian tube to the uterine cavity, the isthmus is the narrowest part near the uterus, and the infundibulum is the funnel-shaped end near the ovary, where the egg is captured after ovulation.

5. Which of these methods can be used for the transfer of zygote or early embryo into the fallopian tube?

• A. GIFT
• B. IUT
• C. ZIFT
• D. ICSI

Correct answer: C

Rationale: The correct answer is C, ZIFT (Zygote Intrafallopian Transfer). ZIFT involves transferring a zygote or early embryo into the fallopian tube. GIFT (Gamete Intrafallopian Transfer - A) involves transferring unfertilized eggs and sperm into the fallopian tube for fertilization to occur inside the woman's body, not a zygote or early embryo. IUT (Intrauterine Transfer - B) is not specifically for transferring the zygote or early embryo into the fallopian tube, but rather into the uterus. ICSI (Intracytoplasmic Sperm Injection - D) is a technique where a single sperm is injected directly into an egg, not related to transferring embryos into the fallopian tube.
