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.

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.
What type of epithelium lines the urinary bladder?
- A. Transitional epithelium.
- B. Stratified epithelium.
- C. Glandular tissue.
- D. Endometrium.
Correct Answer: A
Rationale: The correct answer is A: Transitional epithelium. The urinary bladder is lined with transitional epithelium, a specialized type of epithelial tissue that can stretch and recoil to accommodate changes in volume as the bladder fills and empties. Stratified epithelium (choice B) is not the main lining of the urinary bladder and is found in other areas like the skin. Glandular tissue (choice C) is responsible for producing secretions and is not typically found lining the urinary bladder. Endometrium (choice D) is the inner lining of the uterus and is not present in the urinary bladder.
Appropriate Technologies and Skills:
- A. Must be selected according to universal standards
- B. Involves ensuring the woman delivers at the hospital
- C. Requires specific qualifications such as being a nurse
- D. Necessitates the presence of a doctor at the service providing facility
Correct Answer: A
Rationale: The correct answer is A because appropriate technologies must adhere to universal standards to ensure their effectiveness. Choice B is incorrect because the question is not specifically referring to childbirth. Choice C is incorrect as it limits the scope to only nurses. Choice D is incorrect as it implies the necessity of a doctor, which may not always be the case.
Which structure maintains the uterus in an anteverted and anteflexed position?
- A. Round ligaments
- B. Broad ligaments
- C. Cardinal ligaments
- D. Pubocervical ligaments
Correct Answer: A
Rationale: The correct answer is the Round ligaments. The round ligaments are responsible for maintaining the uterus in an anteverted and anteflexed position. These ligaments attach from the sides of the uterus and extend through the inguinal canal to the labia majora. The other choices, Broad ligaments, Cardinal ligaments, and Pubocervical ligaments, have different functions and attachments within the pelvis. Broad ligaments are a double layer of peritoneum that encloses the uterus and supports the uterine tubes. Cardinal ligaments provide support to the cervix and upper vagina. Pubocervical ligaments support the cervix and bladder.
To minimize unsafe abortions, IRH has strengthened:
- A. The termination of pregnancy act
- B. The post-abortion care and counseling services
- C. The gender and violence unit of the police services
- D. The empowerment of all women who want to abort
Correct Answer: B
Rationale: Post-abortion care and counseling services are crucial in reducing unsafe abortions by providing support, medical care, and guidance to individuals who have undergone abortions, ensuring their physical and emotional well-being. Strengthening the termination of pregnancy act (Choice A) might focus more on the legal aspects rather than the healthcare services needed post-abortion. The gender and violence unit of the police services (Choice C) is important for addressing gender-based violence but not directly related to reducing unsafe abortions. Empowering all women who want to abort (Choice D) is a broad concept that may not specifically address the need for comprehensive post-abortion care and counseling services.
