Which animal is an ovoviviparous animal?
- A. Basking shark
- B. Bonobo
- C. Blue shark
- D. None of the above
Correct Answer: C
Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

What is the most common symptom in all clinical types of abortion EXCEPT:
- A. Lower abdominal pain
- B. Per vaginal bleeding
- C. Show
- D. Backache
Correct Answer: C
Rationale: The correct answer is C. 'Show' is not a common symptom in all types of abortion. Lower abdominal pain, per vaginal bleeding, and backache are common symptoms associated with abortion. Lower abdominal pain may result from uterine contractions, per vaginal bleeding is a typical presentation, and backache can be a symptom due to the process of abortion. 'Show' refers to the mucus plug that blocks the cervix during pregnancy and is not a typical symptom of abortion.
Approximately how many primordial follicles are present in the cortex of the ovary at birth?
- A. 250,000
- B. 200,000
- C. 150,000
- D. 100,000
Correct Answer: A
Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.

Which hormone is detected in pregnancy tests?
- A. Estrogen
- B. Progesterone
- C. Luteinizing hormone (LH)
- D. Human chorionic gonadotropin (hCG)
Correct Answer: D
Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.
During a vaginal examination, which of the following statements is true?
- A. Cervical scrapes cytology can be taken in the same setting.
- B. Preferably done after bimanual examination.
- C. The cervix is best visualized with the Crisco's type of spectrum.
- D. During pregnancy, the cervix feels firm like the tip of the nose.
Correct Answer: C
Rationale: The correct answer is C. The cervix is best visualized with the Cusco's type of spectrum. This statement is true and important during a vaginal examination. Choice A is incorrect because cervical cytology scrapes can be taken during the same setting as a vaginal examination, not necessarily prior to it. Choice B is incorrect as it states 'after' bimanual examination, which is not the typical sequence. Choice D is incorrect because during pregnancy, the cervix feels soft rather than firm like the tip of the nose.
