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. Complete abortion is characterized by:

• A. Os closed.
• B. Firm contracted uterus.
• C. Heavy bleeding.
• D. Heavy cramping.

Correct answer: A

Rationale: Complete abortion is characterized by a firm contracted uterus with a closed os. This closure of the os indicates that the products of conception have been completely expelled from the uterus. Choices B, C, and D are incorrect because a firm contracted uterus with a closed os is the hallmark sign of a complete abortion, not heavy bleeding, heavy cramping, or any other features.

3. What is the purpose of hysteroscopy?

• A. View the uterine cavity
• B. Perform a D&C procedure
• C. Remove the fetus
• D. Visualize the fallopian tubes

Correct answer: A

Rationale: Hysteroscopy is a procedure where a very narrow endoscope is inserted through the cervix to view the uterine cavity. This allows healthcare providers to diagnose and treat various uterine conditions such as polyps, fibroids, and adhesions. Choice B, performing a D&C procedure, involves dilating the cervix and scraping the uterine lining, which is a different procedure. Choice C, removing the fetus, is not the purpose of hysteroscopy and is a procedure done in specific circumstances such as pregnancy termination or miscarriage management. Choice D, visualizing the fallopian tubes, is typically done through a procedure called a hysterosalpingogram, which is different from hysteroscopy.

4. 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.

5. What is the role of relaxin hormone?

• A. Relaxation of the symphysis pubis.
• B. Stimulation of milk production.
• C. Stimulating the development of the nipple and duct system in the breast.
• D. None of the above.

Correct answer: A

Rationale: The correct answer is A: Relaxation of the symphysis pubis. Relaxin hormone is responsible for loosening the ligaments in the pelvic area, particularly the symphysis pubis, to prepare for childbirth. Choice B, stimulation of milk production, is incorrect as this is primarily regulated by prolactin. Choice C, stimulating the development of the nipple and duct system in the breast, is incorrect as this is mainly influenced by estrogen and progesterone during pregnancy. Therefore, the correct role of relaxin hormone is the relaxation of the symphysis pubis.
