Correct Answer: C

Rationale: The correct answer is screening for early signs of disease (Choice C). Secondary prevention focuses on early detection and treatment of diseases to prevent their progression. By screening for early signs of disease, individuals can receive timely interventions, leading to better health outcomes. Administering vaccines (Choice A) falls under primary prevention by preventing the occurrence of diseases. Providing treatment for chronic diseases (Choice B) is part of tertiary prevention, which focuses on managing and reducing complications of established diseases. Offering health education workshops (Choice D) can be part of primary prevention by promoting healthy behaviors to prevent diseases.

Correct Answer: A

Rationale: Interdisciplinary collaboration is crucial in community health as it brings together professionals from different fields to provide a holistic approach to patient care. By integrating various perspectives and expertise, it enhances the quality of care, leading to better health outcomes for the community. This teamwork allows for comprehensive assessments, innovative solutions, and improved coordination of services, ultimately benefiting the overall health and well-being of individuals in the community.

Correct Answer: A

Rationale: Community involvement is a critical component of a health promotion program as it ensures that the program aligns with the community's needs and fosters ownership and sustainability. Engaging the community in the planning, implementation, and evaluation of health promotion initiatives increases their effectiveness and relevance.

Correct Answer: D

Rationale: Improving access to health care is a crucial strategy for addressing health disparities because it ensures that all individuals, regardless of their backgrounds or circumstances, have the opportunity to receive the necessary care they need. By enhancing access to healthcare services, underserved populations can overcome barriers to obtaining crucial medical assistance, ultimately reducing health disparities and promoting better health outcomes for everyone.

Correct Answer: A

Rationale: The correct answer is A: 'Educating policymakers about health issues.' Health advocacy involves advocating for improved health outcomes by influencing policy changes through educating policymakers about health issues. This can lead to systemic changes that benefit public health on a broader scale. Providing direct patient care (Choice B) is important but falls under healthcare delivery rather than advocacy. Organizing community health fairs (Choice C) is a community health promotion activity rather than advocacy. Developing new health technologies (Choice D) is related to innovation and research, not advocacy efforts focused on policy change.
