1. What is the typical measurement of the anterior wall of the vaginal canal?

• A. 10 cm
• B. 11 cm
• C. 11.5 cm
• D. 7.5 cm

Correct answer: D

Rationale: The typical measurement of the anterior wall of the vaginal canal is 7.5 cm. This measurement is anatomically accurate, making choice D the correct answer. Choices A, B, and C provide measurements that are larger than the typical measurement of the anterior wall of the vaginal canal and are therefore incorrect.

2. Which female reproductive organ is positioned directly posterior to the bladder?

• A. Uterine tube
• B. Vagina
• C. Uterus
• D. Ovaries

Correct answer: C

Rationale: The correct answer is the uterus. The uterus is positioned directly posterior to the bladder in the female reproductive system. The uterine tube (choice A) is also known as the fallopian tube, which is not positioned directly posterior to the bladder. The vagina (choice B) is located below the uterus and not directly posterior to the bladder. The ovaries (choice D) are located on either side of the uterus, but they are not positioned directly posterior to the bladder.

3. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. 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.

5. How many arteries are there in an umbilical cord?

• A. Three
• B. One
• C. Two
• D. Four

Correct answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.
