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

• A. Kidneys increase in size, pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases.
• B. Kidneys decrease in size, and glomerular filtration rate decreases.
• C. There is no change in kidney size or ureter function, but the glomerular filtration rate decreases.
• D. Kidneys shrink, and ureters remain the same.

Correct answer: A

Rationale: During pregnancy, the kidneys increase in size, the pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases. This is due to the increased metabolic demands and hormonal changes during pregnancy. Choice B is incorrect as the kidneys do not decrease in size, and the glomerular filtration rate actually increases. Choice C is incorrect as there are changes in kidney size and ureter function during pregnancy. Choice D is incorrect as the kidneys do not shrink during pregnancy.

2. Inevitable abortion occurs when:

• A. The ovum dies in utero and the decidua capsularis remains intact.
• B. The cervix is open, and the products of conception are about to be expelled.
• C. The products of conception are expelled before the 20th week of gestation.
• D. The fetus dies and is expelled in the first trimester.

Correct answer: B

Rationale: Inevitable abortion occurs when the cervix is open, and the products of conception are about to be expelled. This is a critical point in the process of spontaneous abortion, indicating that expulsion of the products of conception is imminent. Choice A is incorrect as it describes a missed abortion where the ovum dies but the decidua capsularis remains intact. Choice C is incorrect as it describes an incomplete abortion where the products of conception are expelled before the completion of 20 weeks of gestation. Choice D is incorrect as it describes a missed abortion where the fetus dies and is expelled in the first trimester.

3. Where does the ovum receive the sperm?

• A. Animal pole
• B. Vegetal pole
• C. Zona pellucida
• D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

4. What is the content of the acrosome?

• A. Lipids
• B. Hormones
• C. Digestive enzymes
• D. None of the above

Correct answer: C

Rationale: The correct answer is C: Digestive enzymes. The acrosome is a structure found in sperm cells that contains enzymes used to penetrate the egg during fertilization. Choice A (Lipids) and Choice B (Hormones) are incorrect as the primary content of the acrosome is digestive enzymes, not lipids or hormones. Choice D (None of the above) is incorrect as the acrosome does contain a specific substance, which are digestive enzymes.

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.
