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

• A. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, blood vasculature increases in size and number, and hypertrophy of myometrial cells occurs.
• B. The uterus decreases in size during pregnancy and remains rigid.
• C. The uterus size remains unchanged, and no changes occur in the blood vasculature.
• D. Uterus becomes more rigid and hypertrophies.

Correct answer: A

Rationale: During pregnancy, the uterus undergoes various anatomical and physiological changes. The correct answer, Choice A, accurately describes these changes. The uterus softens in the anterior midline, becomes flexible at the uterocervical junction, experiences an increase in blood vasculature size and number, and myometrial cells hypertrophy. This softening and increased vascularity are essential for accommodating the growing fetus and facilitating delivery. Choices B, C, and D are incorrect because they do not reflect the typical changes that occur in the uterus during pregnancy. The uterus does not decrease in size, remain unchanged in size, become more rigid, or hypertrophy without the described softening and vascular changes.

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. Inevitable abortion is characterized by:

• A. Heavy bleeding.
• B. Open os.
• C. Severe cramping.
• D. Light bleeding.

Correct answer: B

Rationale: Inevitable abortion is characterized by an open os. This condition is associated with heavy bleeding. While severe cramping can be present in inevitable abortion, the key characteristic is the open os, making choice B the correct answer. Choices A and D are incorrect because they do not specifically describe the defining feature of inevitable abortion, which is the open os.

4. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

5. 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.
