What is the primary benefit of administering Vitamin A to children?
- A. To improve bone health
- B. To boost the immune system
- C. To enhance cognitive development
- D. To prevent anemia
Correct Answer: B
Rationale: The correct answer is B: To boost the immune system. Vitamin A is essential for maintaining a healthy immune system by supporting the production and function of white blood cells. This helps the body fight off infections and illnesses. Administering Vitamin A to children can help prevent deficiencies and strengthen their immune response.
Explanation of why the other choices are incorrect:
A: Vitamin D is more closely associated with improving bone health, not Vitamin A.
C: Cognitive development is primarily influenced by nutrients like iron and omega-3 fatty acids, rather than Vitamin A.
D: Anemia is usually prevented by iron supplementation, not Vitamin A.

What is the goal of the Safe Motherhood Initiative?
- A. To reduce child mortality
- B. To improve maternal health
- C. To provide free medical services
- D. To promote exclusive breastfeeding
Correct Answer: B
Rationale: The goal of the Safe Motherhood Initiative is to improve maternal health. This includes reducing maternal mortality rates and ensuring safe childbirth practices.

Choice A is focused on child mortality, not maternal health. Thus, the correct answer is B as it directly aligns with the main objective of the initiative.
Which of the following is a key strategy in the prevention of mother-to-child transmission of HIV?
- A. Exclusive breastfeeding
- B. Routine immunization
- C. Antiretroviral therapy
- D. Nutritional supplementation
Correct Answer: C
Rationale: The correct answer is C: Antiretroviral therapy. This is a key strategy because it involves giving HIV medications to the mother during pregnancy, labor, and delivery, as well as to the newborn, significantly reducing the risk of transmission. Antiretroviral therapy helps lower the viral load in the mother's body, making it less likely for the virus to be passed on to the child. Exclusive breastfeeding (choice A) can increase the risk of transmission, routine immunization (choice B) does not directly prevent mother-to-child transmission of HIV, and nutritional supplementation (choice D) is not a primary strategy for preventing transmission.
Which of the following is a major risk factor for cardiovascular diseases?
- A. Low cholesterol levels
- B. Physical inactivity
- C. Low blood pressure
- D. Adequate sleep
Correct Answer: B
Rationale: The correct answer is B: Physical inactivity. Physical inactivity is a major risk factor for cardiovascular diseases because regular exercise helps maintain a healthy heart and blood vessels. It reduces the risk of developing conditions like high blood pressure, high cholesterol, and obesity, which are all linked to cardiovascular diseases. In contrast, choices A, C, and D are not major risk factors for cardiovascular diseases. Low cholesterol levels (A) are usually considered beneficial for heart health, low blood pressure (C) is generally a sign of good cardiovascular health, and while adequate sleep (D) is important for overall well-being, it is not directly linked to cardiovascular diseases.
What is the primary benefit of exclusive breastfeeding for the first 6 months of life?
- A. Prevents childhood obesity
- B. Ensures complete nutrition for the infant
- C. Increases the risk of allergies
- D. Delays cognitive development
Correct Answer: B
Rationale: Exclusive breastfeeding for the first 6 months provides complete nutrition for the infant, meeting all their dietary needs. Breast milk contains essential nutrients and antibodies that support healthy growth and development. It also helps to strengthen the baby's immune system and reduce the risk of infections. Ensuring complete nutrition through breastfeeding is crucial for optimal health outcomes in the early stages of life. Preventing childhood obesity, increasing the risk of allergies, and delaying cognitive development are not directly linked to exclusive breastfeeding and are therefore incorrect choices.

- A. Providing acute care in hospitals
- B. Conducting surgeries

A: Providing acute care in hospitals is incorrect as this is typically the role of hospital nurses, not community health nurses.
B: Conducting surgeries is incorrect as this is a task performed by surgeons or operating room nurses, not community health nurses.
D: Diagnosing and treating medical conditions is incorrect as this falls under the responsibility of healthcare providers such as physicians or nurse practitioners, not community health nurses.
