1. Which one is not a barrier method for birth control?

• A. Diaphragms
• B. Cervical caps
• C. Vaults
• D. Intrauterine Devices (IUDs)

Correct answer: D

Rationale: The correct answer is D, Intrauterine Devices (IUDs). Barrier methods of birth control physically block sperm from reaching the egg. Diaphragms, cervical caps, and vaults are examples of barrier methods as they create a barrier that prevents sperm from reaching the cervix. In contrast, IUDs work by altering the cervical mucus and uterine lining, making it difficult for sperm to reach the egg, but they do not physically block sperm like barrier methods do.

2. Which of the following is a common presentation in women with polycystic ovarian syndrome?

• A. Oligomenorrhea, obesity, and hirsutism
• B. Amenorrhea, generalized hair loss, and weight gain
• C. Repeated ectopic pregnancies and chronic pelvic pain
• D. Fatigue, body aches, and menorrhagia

Correct answer: A

Rationale: The correct answer is A: Oligomenorrhea, obesity, and hirsutism. Polycystic ovarian syndrome (PCOS) commonly presents with irregular periods (oligomenorrhea), obesity, and increased hair growth (hirsutism) due to hormonal imbalances. Choice B is incorrect as amenorrhea (absence of periods), generalized hair loss, and weight gain are not typical features of PCOS. Choice C is incorrect as repeated ectopic pregnancies and chronic pelvic pain are not characteristic of PCOS. Choice D is incorrect as fatigue, body aches, and menorrhagia (excessive menstrual bleeding) are not primary symptoms seen in PCOS.

3. Which of the following is an example of an oviparous animal?

• A. Pigeon
• B. Elephant
• C. Sheep
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Pigeon. Oviparous animals are those that lay eggs, and pigeons fall under this category. Choice B, Elephant, is incorrect because elephants are viviparous, giving birth to live young. Choice C, Sheep, is also incorrect as sheep are viviparous animals. Choice D, None of the above, is not the correct answer as a pigeon is indeed an example of an oviparous animal.

4. What is the term used to describe the gestational sac surrounded by a blood clot and retained in the tube?

• A. A carneous mole.
• B. A hydatidiform mole.
• C. A vesicular mole.
• D. A chorionic mole.

Correct answer: A

Rationale: The correct answer is A: a carneous mole. A carneous mole occurs when a gestational sac is surrounded by a blood clot and retained in the tube. Choice B, a hydatidiform mole, is incorrect as it refers to an abnormal pregnancy characterized by the presence of hydropic chorionic villi. Choice C, a vesicular mole, is also incorrect as it is another term for a complete hydatidiform mole. Choice D, a chorionic mole, is not a recognized medical term and is therefore incorrect.

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.'
