Certified in Public Health (CPH) Practice Exam

What is the main function of law in public health?

1. To govern and "police" individual interests of all citizens

2. Coercive interventions aimed at changing individual behaviors

3. Create a mission for public health authorities and specify how they exercise authority

4. Empower governments to act and set limits on power

The correct answer is: Create a mission for public health authorities and specify how they exercise authority

The main function of law in public health is to create a mission for public health authorities and specify how they exercise authority. This option highlights the legal framework that guides public health practices, ensuring that authorities have a clear set of responsibilities and powers to protect the health of the population. Laws in public health establish the goals and objectives that public health agencies are expected to meet, as well as the specific procedures they must follow to achieve these outcomes. By defining the mission of public health authorities, the law serves as a foundational element for the governance of health strategies and interventions, helping to maintain order and ensure accountability. This legal structure is essential for coordinating efforts to address health issues, allocate resources, and implement health policies effectively. The other options do touch upon aspects of law in public health but do not capture the comprehensive and foundational role that law plays in directing and limiting public health authority. While governance and coercive interventions may relate to public health, they do not encompass the broader purpose of establishing a clear mission and framework for public health operations evident in the chosen answer.
