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. During which phase of the menstrual cycle does the Graafian follicle rupture?

• A. Regenerative
• B. Menstruation
• C. Ovulation
• D. Proliferative

Correct answer: C

Rationale: The correct answer is C: Ovulation. The Graafian follicle ruptures during the ovulation phase, releasing the mature egg from the ovary. This process marks the midpoint of the menstrual cycle. Choice A, Regenerative, is incorrect as it does not correspond to a specific phase of the menstrual cycle. Choice B, Menstruation, is incorrect because menstruation is the shedding of the uterine lining and occurs after ovulation if fertilization does not occur. Choice D, Proliferative, is incorrect as it refers to the phase in which the uterine lining thickens in preparation for a potential embryo implantation, which happens after ovulation.

3. 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.

4. What phase corresponds with the luteal phase?

• A. Menstrual phase
• B. Follicular phase
• C. Secretory phase
• D. Menstrual phase

Correct answer: C

Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.

5. Which one is not a barrier method for birth control?

• A. Diaphragms
• B. Cervical caps
• C. Vaults
• D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.
