1. Which of the following is an example of a viviparous animal?

A. Goat
B. Duck
C. Crocodile
D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

2. At 3-4 weeks of pregnancy, the breast changes include:

A. Darkening of the nipple.
B. Prickling, tingling sensation.
C. Breast becomes tender.
D. Colostrum can be expressed.

Correct answer: C

Rationale: At 3-4 weeks of pregnancy, breast changes commonly involve tenderness due to hormonal fluctuations. Darkening of the nipple (Choice A) typically occurs later in pregnancy. Prickling, tingling sensations (Choice B) are more associated with early pregnancy due to increased blood flow to the breast area. Colostrum production (Choice D) usually begins later in pregnancy, closer to the end of the third trimester.

3. Which phase of the menstrual cycle is variable?

A. Ovulatory
B. Regenerative
C. Secretory
D. Menstrual

Correct answer: B

Rationale: The regenerative phase of the menstrual cycle is the phase in which the endometrium rebuilds after menstruation. This phase can vary in duration from woman to woman and cycle to cycle. Choice A, the ovulatory phase, is not variable as it typically lasts around 24 hours. Choice C, the secretory phase, is also relatively consistent in its duration. Choice D, the menstrual phase, is the shedding of the endometrial lining and usually lasts around 3-7 days.

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. 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.
