What is the primary benefit of administering Vitamin A to children?

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.

Correct Answer: C

Rationale: The correct answer is C: 12 months. The first dose of the MMR vaccine is typically administered at 12 months of age because this is when a child's immune system is more developed to respond effectively to the vaccine. Administering it earlier may not provide adequate protection. Choice A (At birth) is incorrect because newborns have maternal antibodies that can interfere with the vaccine's efficacy. Choice B (6 months) is too early as infants need time to develop their immune system. Choice D (18 months) is also incorrect as delaying the vaccine may leave the child vulnerable to diseases like measles, mumps, and rubella.

Correct Answer: B

Rationale: The correct answer is B: Nutritional counseling. Prenatal care focuses on ensuring the health of both the mother and the developing baby. Proper nutrition is essential for the well-being of both, as it supports the baby's growth and development and helps prevent complications for the mother. Nutritional counseling provides guidance on maintaining a balanced diet, taking necessary supplements, and managing any dietary restrictions during pregnancy. Routine immunizations (A) are important but not typically a primary component of prenatal care. Surgical interventions (C) and radiologic exams (D) are generally avoided during pregnancy unless absolutely necessary due to potential risks to the fetus. Therefore, B is the most essential component for prenatal care.

Correct Answer: B

Rationale: The correct action is to delay the immunization until the fever subsides. This is because administering a vaccine during a fever may affect the body's immune response and efficacy of the vaccine. Giving a lower dose (choice C) may not provide adequate protection. Administering an antipyretic (choice D) may temporarily reduce fever but does not address the underlying illness causing the fever. Administering the vaccine as scheduled (choice A) can be harmful and is not recommended when the child has a fever.

Correct Answer: B

Rationale: The correct answer is B: Airborne. Tuberculosis is primarily transmitted through the air via droplets released when an infected person coughs or sneezes. These droplets contain the bacteria that cause TB, which can then be inhaled by others and infect their lungs. This mode of transmission is supported by scientific evidence and is the most common way TB spreads. Choice A: Vector-borne is incorrect because tuberculosis is not transmitted by insects or animals. Choice C: Waterborne is incorrect as TB is not typically spread through contaminated water. Choice D: Fecal-oral is incorrect since TB bacteria are not typically found in feces and transmitted through oral ingestion.

Correct Answer: B

Rationale: The correct answer is B: Community participation. This is a key principle of Primary Health Care (PHC) as it emphasizes involving communities in decision-making, planning, and implementation of healthcare services. Community participation ensures that healthcare services are culturally appropriate, accessible, and meet the specific needs of the population. It also promotes empowerment and ownership of health initiatives within the community. Centralized health planning (A) goes against the decentralized and community-focused approach of PHC. Focus on specialized care (C) contradicts the comprehensive and holistic nature of PHC. High technology healthcare (D) may not always be feasible or accessible in resource-limited settings, which is a key consideration in PHC implementation.

Correct Answer: B

Rationale: The primary goal of health education is to change behavior for improved health. This involves educating individuals on healthy lifestyle choices, preventive measures, and disease management strategies. By empowering individuals with knowledge and skills, health education aims to promote better health outcomes. Diagnosing diseases (choice A) and providing emergency medical care (choice C) are responsibilities of healthcare professionals, not the primary goal of health education. Performing surgeries (choice D) is a medical intervention and not within the scope of health education's primary goal.

Correct Answer: C

Rationale: The primary goal of the Integrated Management of Childhood Illness (IMCI) strategy is to reduce child mortality and morbidity. This strategy focuses on providing holistic care to children, including early detection and treatment of common childhood illnesses. By improving healthcare access and quality, IMCI aims to decrease the number of children dying from preventable diseases. Explanation: A: Reducing the incidence of childhood diseases is important but not the primary goal of IMCI. The strategy is more focused on reducing mortality and morbidity. B: Improving nutritional status is essential for child health but is not the primary goal of IMCI. D: Promoting exclusive breastfeeding is a key component of child health but is not the primary goal of IMCI.

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.
