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. 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.'

3. What are the Carunculae Myrtiformes?

• A. Tissues between the vagina and the perineum
• B. A component of the clitoral prepuce
• C. The remnants of the torn hymen
• D. Structures that partially close the vaginal introitus

Correct answer: C

Rationale: The Carunculae Myrtiformes are the remnants of the torn hymen. They are not tissues between the vagina and the perineum (Choice A), a part of the clitoral prepuce (Choice B), or structures that partially close the vaginal introitus (Choice D). Understanding the anatomy of the female reproductive system is crucial for healthcare professionals to provide accurate care and information.

4. Which of the following hormone ratios is MOST likely to be increased in a patient with PCOS?

• A. Progesterone/estrogen
• B. LH/FSH
• C. FSH/LH
• D. Glucagon/insulin

Correct answer: B

Rationale: In patients with Polycystic Ovary Syndrome (PCOS), the LH/FSH ratio is most likely to be increased. This hormonal imbalance is a key characteristic of PCOS, where elevated LH levels relative to FSH contribute to the pathophysiology of the condition. Choice A, progesterone/estrogen ratio, is not typically a defining feature of PCOS. Choice C, FSH/LH ratio, is the reverse of what is commonly observed in PCOS. Choice D, glucagon/insulin ratio, is not directly related to the hormonal imbalances seen in PCOS.

5. The weight of the non-pregnant uterus is approximately ___________grams.

• A. 57
• B. 80
• C. 66
• D. 71

Correct answer: B

Rationale: The correct answer is B: 80. The non-pregnant uterus typically weighs around 80 grams. This weight may vary slightly among individuals, but 80 grams is a commonly accepted average. Choices A, C, and D are incorrect as they do not reflect the typical weight of the non-pregnant uterus. It is important to remember this approximate weight for medical reference and understanding of normal anatomical variations.
