Which department of the Government ministries was given the mandate to pilot a draft population policy?
- A. The department of planning and development
- B. National census
- C. Human rights
- D. Central statistics
Correct Answer: A
Rationale: The correct answer is A: The department of planning and development. In the extract provided, it explicitly mentions that this department was tasked with piloting the population policy.

How does human sperm move?
- A. Flagella
- B. Cilia
- C. Neutrophils
- D. None of the above
Correct Answer: A
Rationale: Human sperm moves using flagella, which are whip-like structures that aid in propulsion. Flagella are tail-like structures found in sperm cells and help them swim towards the egg for fertilization. Cilia are shorter, hair-like structures that are not involved in the movement of sperm. Neutrophils are a type of white blood cell involved in the immune response and are not related to sperm locomotion.
The upper folds of the labia minora surround the clitoris and unite to form the:
- A. Frenulum
- B. Prepuce
- C. Fourchette
- D. Vestibule
Correct Answer: B
Rationale: The correct answer is B: Prepuce. The upper folds of the labia minora surround the clitoris and unite to form the prepuce, which is a hood-like structure protecting the clitoris. The frenulum (choice A) is a small fold of tissue under the tongue or upper lip, not related to the female genitalia. The fourchette (choice C) refers to the area where the labia minora meet at the posterior end of the vulva, not involving the clitoris. The vestibule (choice D) is the space between the labia minora containing the vaginal and urethral openings, not directly formed by the upper folds of the labia minora.
At 6-8 weeks of pregnancy, the breast changes include:
- A. Colostrum can be expressed.
- B. Breasts become tender.
- C. Montgomery's tubercles are prominent.
- D. Nipples become prominent and mobile.
Correct Answer: C
Rationale: At 6-8 weeks of pregnancy, one of the changes in the breast includes the prominence of Montgomery's tubercles. These sebaceous glands around the nipple become more noticeable at this stage. Colostrum production usually occurs later in pregnancy, typically closer to the third trimester. While breast tenderness is a common symptom of early pregnancy, it is not specific to the 6-8 week timeframe. Nipples becoming more prominent and mobile may happen later in pregnancy as the body prepares for breastfeeding, but it is not a typical change seen specifically at 6-8 weeks.
Which of the following is not a role of Reproductive and Child Health Care (RCH) programs?
- A. Awareness about reproductive health
- B. Providing facilities to build a reproductively healthy society
- C. Providing support to reproductively sick people
- D. Promoting abortion
Correct Answer: D
Rationale: The correct answer is D. Promoting abortion is not a role of the Reproductive and Child Health Care (RCH) programs. RCH programs focus on promoting awareness about reproductive health, providing facilities to build a reproductively healthy society, and offering support to reproductively sick individuals. The promotion of abortion is not within the scope of RCH programs, which aim to improve maternal and child health outcomes through education, healthcare services, and support systems.
