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.

Which nutrient is essential for preventing anemia in pregnant women?
- A. Vitamin C
- B. Vitamin D
- C. Iron
- D. Calcium
Correct Answer: C
Rationale: The correct answer is C: Iron. Iron is essential for preventing anemia in pregnant women because it is a key component of hemoglobin, the protein in red blood cells that carries oxygen to tissues and organs. During pregnancy, the demand for iron increases to support the growing fetus and the mother's increased blood volume. Without adequate iron intake, pregnant women are at a higher risk of developing iron-deficiency anemia, which can lead to complications for both the mother and the baby.
Other choices are incorrect because:
A: Vitamin C is important for iron absorption but does not directly prevent anemia.
B: Vitamin D is important for bone health but does not prevent anemia.
D: Calcium is important for bone health but does not prevent anemia in pregnant women.
Which vaccine is typically administered to newborns within the first 24 hours of birth?
- A. Hepatitis B
- B. BCG
- C. OPV
- D. Measles
Correct Answer: A
Rationale: The correct answer is A: Hepatitis B. Newborns are typically administered the Hepatitis B vaccine within the first 24 hours of birth to prevent transmission from infected mothers. This early vaccination helps protect infants from a potentially serious viral infection. The other choices are incorrect because BCG is usually given for tuberculosis, OPV is an oral polio vaccine, and Measles vaccination is typically given at a later age. Administering Hepatitis B vaccine to newborns is a crucial preventive measure against a common viral infection transmitted from mother to child.
Which of the following is an example of a preventive measure in public health?
- A. Chemotherapy
- B. Vaccination
- C. Radiation therapy
- D. Surgical intervention
Correct Answer: B
Rationale: The correct answer is B: Vaccination. Preventive measures aim to prevent diseases before they occur. Vaccination helps the immune system recognize and fight specific pathogens, reducing the risk of infection and disease transmission. Chemotherapy (A) is a treatment for cancer, not prevention. Radiation therapy (C) and surgical intervention (D) are also treatments rather than preventive measures. Vaccination stands out as the only option that directly addresses disease prevention, making it the correct choice.
Which of the following is an example of secondary prevention?
- A. Vaccination
- B. Health education
- C. Screening for hypertension
- D. Rehabilitation therapy
Correct Answer: C
Rationale: Secondary prevention aims to detect and treat a disease in its early stages to prevent complications. Screening for hypertension (Choice C) is an example as it involves identifying individuals at risk of developing high blood pressure-related issues. Vaccination (Choice A) is a form of primary prevention. Health education (Choice B) is more focused on promoting healthy behaviors. Rehabilitation therapy (Choice D) is part of tertiary prevention, aimed at improving function after a disease has occurred.
Which of the following interventions is an example of tertiary prevention?
- A. Vaccination campaigns
- B. Health education seminars
- C. Physical rehabilitation programs
- D. Early disease screening
Correct Answer: C
Rationale: Tertiary prevention focuses on managing and improving quality of life for individuals with existing health conditions. Physical rehabilitation programs fall under this category as they help individuals recover and regain functioning after an illness or injury. This intervention aims to prevent further complications and disabilities. Vaccination campaigns (A) and health education seminars (B) are examples of primary and secondary prevention, focusing on preventing diseases before they occur or detecting them early. Early disease screening (D) is also a form of secondary prevention, aiming to detect diseases in their early stages before symptoms appear.
