1. The patient about to undergo gynecological surgery is put on nil by mouth for ____ before surgery to prevent aspiration.

• A. 2-4 hours
• B. 3-5 hours
• C. 4-6 hours
• D. 5-7 hours

Correct answer: C

Rationale: Patients undergoing gynecological surgery are typically advised to be nil by mouth for 4-6 hours before the procedure to reduce the risk of aspiration. This duration allows the stomach to empty its contents, decreasing the likelihood of regurgitation and aspiration of stomach contents during surgery. Choices A, B, and D have shorter durations and may not provide sufficient time for adequate gastric emptying, increasing the risk of aspiration.

2. What action does the copper used in Copper T have?

• A. Blastocidal
• B. Bacteriostatic
• C. Bacteriocidal
• D. Spermicidal

Correct answer: D

Rationale: The correct answer is D, Spermicidal. The copper in Copper T exerts its action by affecting sperm viability and motility, thus preventing fertilization. Choices A, B, and C are incorrect because Copper T primarily works by preventing sperm from reaching and fertilizing the egg, rather than acting on blastocysts, bacteria, or bacteriocins.

3. Discuss the anatomical/physiological changes in pregnancy under the following: Cardiovascular system

• A. The heart is displaced upward and to the left by the enlarging uterus, cardiac capacity increases, and blood pressure declines slightly.
• B. The heart is displaced downward and to the right, and blood pressure increases.
• C. The cardiovascular system remains unchanged during pregnancy.
• D. Cardiovascular changes include increased peripheral resistance and reduced cardiac output.

Correct answer: A

Rationale: During pregnancy, the cardiovascular system undergoes changes such as the heart being displaced upward and to the left by the enlarging uterus, increased cardiac capacity, and a slight decline in blood pressure. Choice B is incorrect as the heart is displaced upwards, not downwards, and blood pressure typically decreases slightly. Choice C is incorrect as the cardiovascular system does undergo changes during pregnancy. Choice D is incorrect as cardiovascular changes in pregnancy involve increased cardiac output rather than reduced output.

4. Which of the following structures is responsible for the production of sperm?

• A. Epididymis
• B. Seminal vesicles
• C. Testes
• D. Prostate gland

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.

5. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.
