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. 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.

3. Treatment for condylomata acuminata includes the following EXCEPT:

• A. Vulvectomy
• B. Podophyllin application
• C. Laser therapy
• D. Electrocautery

Correct answer: A

Rationale: The correct answer is A. Vulvectomy is not a standard treatment for condylomata acuminata, which are genital warts caused by human papillomavirus (HPV). Surgical removal of the vulva (vulvectomy) is an extreme measure and not typically indicated for treating this condition. Choices B, C, and D are valid treatments for condylomata acuminata. Podophyllin application, laser therapy, and electrocautery are commonly used to remove or destroy genital warts caused by HPV. These treatments aim to eliminate the visible warts and clear the infection.

4. 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.

5. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

• A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
• B. Blood volume and plasma volume decrease, and red blood cells decrease.
• C. No changes occur in the haematological system during pregnancy.
• D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.
