1. 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.

2. Which of the following is a contraceptive?

• A. Copper T
• B. Condom
• C. Diaphragm
• D. All of these

Correct answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

3. What are the external organs of the female collectively known as?

• A. Vulva
• B. Frenulum
• C. Mons veneris
• D. Vestibule

Correct answer: A

Rationale: The correct answer is A: Vulva. The external organs of the female reproductive system, including the labia majora, labia minora, clitoris, vaginal opening, and Bartholin's glands, are collectively known as the vulva. Choice B, Frenulum, is incorrect as it refers to a small band of tissue. Choice C, Mons veneris, specifically refers to the rounded mass of fatty tissue located over the pubic bone, not all external female reproductive organs. Choice D, Vestibule, is incorrect as it is the space enclosed by the labia minora that includes the vaginal and urethral openings, not all external female reproductive organs.

4. Which of the following are layers of endometrium in pregnancy EXCEPT?

• A. Decidua compacta
• B. Decidua spongiosum
• C. Decidua functionalis
• D. Decidua basalis

Correct answer: C

Rationale: During pregnancy, the layers of endometrium include decidua compacta, decidua spongiosum, and decidua basalis. Decidua functionalis is the layer that sheds during menstruation and regenerates each cycle, not a layer of the endometrium during pregnancy. Therefore, choice C is the correct answer. Decidua compacta is the layer closest to the conceptus, decidua spongiosum is the middle layer, and decidua basalis is the layer adjacent to the myometrium.

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

• A. Kidneys increase in size, pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases.
• B. Kidneys decrease in size, and glomerular filtration rate decreases.
• C. There is no change in kidney size or ureter function, but the glomerular filtration rate decreases.
• D. Kidneys shrink, and ureters remain the same.

Correct answer: A

Rationale: During pregnancy, the kidneys increase in size, the pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases. This is due to the increased metabolic demands and hormonal changes during pregnancy. Choice B is incorrect as the kidneys do not decrease in size, and the glomerular filtration rate actually increases. Choice C is incorrect as there are changes in kidney size and ureter function during pregnancy. Choice D is incorrect as the kidneys do not shrink during pregnancy.
