• A. The science of protecting and improving the health of populations
• B. A focus on individual patient care
• C. The study of diseases in hospital settings
• D. An approach to enhancing medical technologies

Answer: (A)

Public health can best be defined as the science of protecting and improving the health of populations. This definition encompasses a broad range of activities designed to prevent disease, prolong life, and promote health through organized efforts at the community, state, and national levels. Public health focuses not only on individual health but also on the health and well-being of entire populations, aiming to address health disparities and improve access to health resources. The emphasis on population health rather than individual patient care is crucial, as it involves collective strategies that influence health outcomes, such as vaccination programs, health education, policy-making, and monitoring environmental and social factors affecting health. It incorporates a variety of disciplines, including epidemiology, biostatistics, and social sciences, to understand health trends and implement effective interventions. In contrast, other options such as focusing solely on individual patient care, studying diseases in hospital settings, or enhancing medical technologies reflect narrower scopes that do not encompass the holistic and preventive aims central to public health's mission.
