Which age group is most vulnerable to protein-energy malnutrition (PEM)?

Correct Answer: B

Rationale: The correct answer is B: Children aged 1-4 years. This age group is most vulnerable to PEM due to their rapid growth and development, high energy requirements, and dependency on caregivers for nutrition. Infants below 6 months are typically protected by breast milk, adolescents have lower risk due to fewer growth demands, and elderly are more at risk for other types of malnutrition. Therefore, children aged 1-4 years are the most vulnerable to PEM.

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.

Correct Answer: B

Rationale: The correct answer is B: 6 months. Exclusive breastfeeding is recommended by WHO for the first 6 months of a baby's life. This is because breast milk provides all the essential nutrients and antibodies needed for a baby's optimal growth and development during this critical period. Introducing other foods or liquids before 6 months can increase the risk of infections and allergies in infants. Choices A, C, and D are incorrect because they do not align with the WHO guidelines for exclusive breastfeeding duration.

Correct Answer: C

Rationale: The correct answer is C: Breast milk. Breast milk is the best type of milk for infants below 6 months of age because it provides the ideal nutrition and antibodies necessary for their growth and development. It contains the perfect balance of nutrients, is easily digestible, and helps protect infants from infections and diseases. Choice A: Cow's milk is not recommended for infants below 6 months as it is difficult for them to digest and lacks essential nutrients like iron and vitamin E. Choice B: Goat's milk is also not recommended for infants below 6 months as it lacks certain nutrients and may cause allergic reactions. Choice D: Soy milk is not suitable as a primary source of nutrition for infants below 6 months as it may not provide all the necessary nutrients and can lead to digestive issues. In summary, breast milk is the best choice for infants below 6 months due to its unique composition and numerous benefits compared to other types of milk.

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: C

Rationale: The correct answer is C: Community-wide health promotion and disease prevention. Community health nursing focuses on promoting health and preventing diseases within the community as a whole through education, advocacy, and collaboration. This includes addressing social determinants of health and implementing population-based interventions. Choice A is incorrect because community health nursing goes beyond individual patient care. Choice B is incorrect as it is more focused on acute care within hospital settings. Choice D is incorrect as it pertains to specialized medical treatment rather than the broader scope of community health nursing. In summary, the primary focus of community health nursing is on improving the health of the entire community through preventative measures and health promotion initiatives.

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.

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.

Correct Answer: B

Rationale: The correct answer is B: Achieving a level of health that enables all people to lead economically productive lives. This is the main focus of WHO's Health For All strategy as it aims to ensure that individuals have good health to actively participate in society and the economy. Choice A is incorrect as the strategy doesn't necessarily focus on providing free healthcare to all individuals, but rather on improving overall health outcomes. Choice C is incorrect as simply building more hospitals and clinics does not address the holistic approach of the Health For All strategy. Choice D is incorrect as increasing the number of healthcare workers is important, but the main focus is on achieving better health outcomes for economic productivity.
