1. What is one role of the hormone estrogen?

• A. Stimulates the development of the milk-producing tissue.
• B. Stimulates the production of lactoferrin.
• C. Stimulates the development of the nipple and duct system in the breast.
• D. Stimulates the secretion of relaxin.

Correct answer: A

Rationale: The correct answer is A: Estrogen stimulates the development of the milk-producing tissue in the breast. This hormone is essential in preparing the breast for milk production. Choice B is incorrect because lactoferrin production is not a primary role of estrogen. Choice C is incorrect as estrogen primarily influences the development of the breast tissue rather than specifically the nipple and duct system. Choice D is incorrect because relaxin secretion is not a function typically associated with estrogen.

2. What is the role of the prolactin hormone?

• A. Stimulates the development of milk-producing tissue.
• B. Stimulates milk storage.
• C. Stimulates milk production.
• D. Stimulates milk ejection.

Correct answer: C

Rationale: The correct answer is C: 'Stimulates milk production.' Prolactin hormone is responsible for promoting the production of milk in the mammary glands. This hormone does not directly stimulate the development of milk-producing tissue (Choice A), milk storage (Choice B), or milk ejection (Choice D). While these functions are related to lactation, the primary role of prolactin is to facilitate milk production.

3. Which one of the following is not associated with poor maternal outcome?

• A. APH
• B. PPH
• C. Cord prolapse
• D. Pre-eclampsia

Correct answer: C

Rationale: Cord prolapse is not typically associated with poor maternal outcomes. Acute placental hemorrhage (APH - choice A) and postpartum hemorrhage (PPH - choice B) can lead to maternal morbidity and mortality due to excessive blood loss. Pre-eclampsia (choice D) is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, which can result in severe maternal complications if not managed promptly. Cord prolapse, though concerning for fetal well-being, does not inherently pose direct risks to maternal health if managed appropriately, making it the correct answer in this context.

4. 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.

5. How do contraceptive oral pills help in birth control?

• A. Preventing ovulation
• B. Killing ova
• C. Killing sperms
• D. More than one of the above

Correct answer: A

Rationale: Contraceptive oral pills primarily work by preventing ovulation, which means Choice A is correct. Choices B and C are incorrect because oral contraceptive pills do not kill ova or sperms. Choice D is incorrect because only preventing ovulation is the primary mechanism of action for oral contraceptive pills.
