Which of the following is the most effective method for preventing the spread of infectious diseases?
- A. Antibiotic treatment
- B. Quarantine of infected individuals
- C. Vaccination
- D. Nutritional supplementation
Correct Answer: C
Rationale: The correct answer is C: Vaccination. Vaccination is the most effective method for preventing the spread of infectious diseases because it helps build immunity against specific pathogens, reducing the likelihood of infection and transmission. Vaccines train the immune system to recognize and fight off harmful microorganisms. Antibiotic treatment (A) is used to treat bacterial infections, not prevent the spread of diseases. Quarantine (B) is effective in isolating infected individuals but does not prevent the initial spread of diseases. Nutritional supplementation (D) can support overall health but is not a direct method for preventing infectious diseases.

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 an appropriate method for treating dehydration in infants?
- A. Administering oral rehydration solution
- B. Providing fruit juice
- C. Increasing milk intake
- D. Administering antibiotics
Correct Answer: A
Rationale: The correct answer is A: Administering oral rehydration solution. This is the appropriate method for treating dehydration in infants because it helps replace lost fluids and electrolytes effectively. Oral rehydration solution contains the right balance of water, salts, and sugars needed to rehydrate the infant. It is safe and easy for infants to consume. Providing fruit juice (B) is not recommended as it may contain too much sugar and not enough electrolytes. Increasing milk intake (C) can worsen dehydration due to difficulty digesting milk during dehydration. Administering antibiotics (D) is not necessary for dehydration treatment as it does not address the primary issue of fluid and electrolyte loss.
Which nutrient is most critical for preventing neural tube defects during pregnancy?
- A. Iron
- B. Calcium
- C. Folic acid
- D. Vitamin D
Correct Answer: C
Rationale: The correct answer is C: Folic acid. Folic acid is critical for preventing neural tube defects as it is essential for proper development of the neural tube in the fetus. It helps in the formation of the baby's brain and spinal cord. Iron (A) is important for preventing anemia, not neural tube defects. Calcium (B) is crucial for bone health but not directly related to neural tube development. Vitamin D (D) is important for calcium absorption, but not specifically for preventing neural tube defects. Overall, folic acid stands out as the most critical nutrient for this purpose.
Which of the following is an essential component of a comprehensive antenatal care program?
- A. Weight monitoring
- B. Blood pressure measurement
- C. Nutritional counseling
- D. All of the above
Correct Answer: D
Rationale: Step 1: Weight monitoring is crucial to assess maternal health and fetal growth.
Step 2: Blood pressure measurement helps detect and manage hypertension in pregnancy.
Step 3: Nutritional counseling ensures proper intake of nutrients for maternal and fetal well-being.
Step 4: All components (A, B, C) are essential for a comprehensive antenatal care program to address different aspects of maternal and fetal health. Thus, D is the correct answer. Weight monitoring, blood pressure measurement, and nutritional counseling are all vital components of antenatal care to ensure the well-being of both the mother and the baby.
What is a key objective of the Global Immunization Vision and Strategy (GIVS)?
- A. Eliminating non-communicable diseases
- B. Improving access to high-quality immunization services
- C. Reducing the cost of healthcare
- D. Increasing the number of healthcare professionals
Correct Answer: B
Rationale: The correct answer is B: Improving access to high-quality immunization services. GIVS aims to ensure that everyone has access to vaccines and immunization services to prevent vaccine-preventable diseases. This objective aligns with the overall goal of increasing vaccination coverage and reducing the burden of vaccine-preventable illnesses globally. Choice A is incorrect as GIVS focuses on communicable diseases, not non-communicable diseases. Choice C is incorrect as GIVS aims to improve access to immunization services, not necessarily reduce the cost of healthcare. Choice D is incorrect as GIVS does not specifically target increasing the number of healthcare professionals, but rather improving access to immunization services.
