1. Risk of endometrial hyperplasia is greatest in individuals who do not menstruate for at least _____ months and require immediate referral:

• A. 2 months
• B. 3 months
• C. 4 months
• D. 5 months

Correct answer: C

Rationale: The correct answer is C: '4 months.' The risk of endometrial hyperplasia is highest in individuals who do not menstruate for at least 4 months. This prolonged exposure to unopposed estrogen can lead to endometrial hyperplasia. Choices A, B, and D are incorrect because the risk is greatest after at least 4 months of not menstruating, not 2, 3, or 5 months.

2. Which of the following is used to differentiate abdominal mass from pelvic mass on clinical examination?

• A. Size
• B. Site
• C. Margins
• D. Lower border

Correct answer: D

Rationale: The lower border is used to differentiate between an abdominal mass and a pelvic mass during clinical examination. The lower border of the mass provides important information about its location and origin. The size (Choice A) alone may not always clearly distinguish between abdominal and pelvic masses. The site (Choice B) and margins (Choice C) are also important factors, but they are not as specific in differentiating between abdominal and pelvic masses as the lower border.

3. During the menstrual cycle, which hormone maintains the corpus luteum?

• A. Luteinizing hormone
• B. Follicle-stimulating hormone
• C. Progesterone
• D. Relaxin

Correct answer: A

Rationale: During the menstrual cycle, luteinizing hormone maintains the corpus luteum. The correct answer is A. Luteinizing hormone stimulates the corpus luteum to produce progesterone. Choice B, Follicle-stimulating hormone, is involved in stimulating the growth of follicles in the ovaries. Choice C, Progesterone, is produced by the corpus luteum and plays a role in preparing the endometrium for implantation. Choice D, Relaxin, is involved in processes such as softening the cervix and ligaments during pregnancy, but it is not responsible for maintaining the corpus luteum.

4. What term is used to refer to the fertilized ovum?

• A. Zygote
• B. Embryo
• C. Foetus
• D. Pregnancy

Correct answer: A

Rationale: The correct answer is A, Zygote. A zygote is formed when a sperm cell fertilizes an egg cell. It is the initial stage of prenatal development. Choice B, Embryo, refers to the stage of prenatal development after the zygote and before the foetus. Choice C, Foetus, is the stage of prenatal development after the embryo. Choice D, Pregnancy, is a broader term referring to the condition of having a developing baby in the uterus.

5. 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.'
