1. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

2. Causes of metrorrhagia include:

• A. Cervical carcinoma
• B. Uterine polyp
• C. Cervical endometriosis
• D. Infections like Chlamydia

Correct answer: A

Rationale: Metrorrhagia refers to irregular menstrual bleeding that occurs between periods. Cervical carcinoma, a type of cancer that develops in the cervix, can lead to metrorrhagia. Uterine polyps, which are growths attached to the inner wall of the uterus, can also cause abnormal bleeding. While infections like Chlamydia can cause abnormal vaginal bleeding, they are not common causes of metrorrhagia. Cervical endometriosis, although a possible gynecological condition, is not a typical cause of metrorrhagia. Therefore, the correct answer is cervical carcinoma as it is a known cause of metrorrhagia, making the other options incorrect.

3. The Wolffian duct is also known as ____________.

• A. Mesonephric duct
• B. Ejaculatory duct
• C. Major sublingual duct
• D. Cystic duct

Correct answer: A

Rationale: The correct answer is A: Mesonephric duct. The Wolffian duct is indeed also known as the mesonephric duct. This duct plays a vital role in the development of the male reproductive system by carrying sperm from the epididymis to the ejaculatory duct. Choice B, Ejaculatory duct, is incorrect as it refers to a different duct responsible for transporting semen from the vas deferens. Choices C and D, Major sublingual duct and Cystic duct, are unrelated to the Wolffian duct and are not correct answers in this context.

4. Which of the following is included in a pelvic examination?

• A. Inspection of internal genitalia
• B. Inspection of the cervix and vaginal wall
• C. Palpation of the vagina and vaginal cervix by digital examination
• D. Rectal examination

Correct answer: B

Rationale: The correct answer is B. A pelvic examination involves the inspection of the cervix and vaginal wall. This is typically done to assess the health of the reproductive organs and screen for any abnormalities. Choices A, C, and D are incorrect because while palpation and digital examination may be part of a pelvic exam, the specific focus on the cervix and vaginal wall is a key component that distinguishes it from other types of examinations.

5. At 16 weeks of pregnancy, the breast changes include:

• A. Montgomery's tubercles are prominent.
• B. Darkening of the nipple.
• C. Prickling, tingling sensation.
• D. Colostrum can be expressed.

Correct answer: C

Rationale: At 16 weeks of pregnancy, the sensation of prickling and tingling in the breasts is common due to hormonal changes. Montgomery's tubercles becoming prominent is more characteristic of early pregnancy, typically around the first trimester. Darkening of the nipple, known as areola darkening, can occur but is more commonly observed later in pregnancy. The expression of colostrum, the first milk produced by the mammary glands, usually happens closer to the end of pregnancy or after childbirth, not typically at 16 weeks.
