What is the primary focus of public health?

Correct Answer: A

Rationale: The primary focus of public health is preventing disease and promoting health. This is because public health aims to improve the overall health of populations through preventive measures such as vaccinations, health education, and policy interventions. By focusing on prevention, public health addresses the root causes of health issues and promotes well-being on a larger scale. Providing health education (choice B) is a component of public health but not the primary focus. Ensuring access to health care services (choice C) is important but falls under healthcare delivery rather than public health. Reducing health disparities (choice D) is a goal of public health but not the primary focus, as it is a part of the broader mission to promote health equity.

Correct Answer: B

Rationale: The correct answer is B because community health nursing focuses on improving the quality of life for individuals and families through health promotion and disease prevention. This encompasses a holistic approach that considers social determinants of health and empowers communities to make informed decisions. Providing curative services (A) is not the primary focus of community health nursing, as it aims to prevent illness before it occurs. Conducting research (D) is important but not a key objective of direct community health nursing practice. While promoting health and preventing disease (C) is a key objective, improving the quality of life (B) captures the overarching goal of community health nursing more comprehensively.

Correct Answer: B

Rationale: The correct answer is B, administering vaccines to prevent disease. This is a primary prevention strategy as it aims to prevent the occurrence of disease before it occurs. Vaccines stimulate the immune system to produce an immune response against specific pathogens, reducing the risk of infection and transmission. Educating children on handwashing (A) is important for hygiene but falls under health promotion, not primary prevention. Screening for early signs of disease (C) is secondary prevention, aiming to detect disease at an early stage to prevent complications. Providing treatment for acute illnesses (D) is tertiary prevention, focusing on managing and minimizing the impact of existing conditions.

Correct Answer: A

Rationale: The correct answer is A because socioeconomic status influences access to resources like nutritious food, safe housing, and healthcare services, directly impacting health outcomes. This is supported by numerous studies showing the link between lower socioeconomic status and higher rates of chronic diseases. Choices B and C are incorrect as socioeconomic status does have a significant impact on health, not just mental health. Choice D is incorrect as genetic predisposition to diseases is determined by genetics, not socioeconomic status.

Correct Answer: B

Rationale: The correct answer is B: Eliminating health disparities among populations. This is the primary objective of public health as it focuses on ensuring that all individuals have equal access to healthcare and resources to achieve optimal health outcomes. By addressing disparities, public health aims to promote health equity and reduce inequalities in health status. Lowering chronic diseases (A) and extending life expectancy (D) are important goals but not the primary objective. Delivering health education (C) is a strategy within public health but not the main objective.
