Which response is associated with nonfeasance in public health regulations?

Nonfeasance in public health regulations refers to the failure to act when there is a responsibility to do so, especially in the presence of a known health hazard. Choosing to ignore a known health hazard exemplifies nonfeasance because it involves an obligation to address a situation that could pose a risk to public health but choosing not to do anything about it. This negligence can lead to further complications, such as the spread of disease or other health issues, because the threat remains unmitigated.

In contrast, taking action against dangerous practices, reporting unsafe conditions, and regulating compliant actions all represent active steps that are taken to protect public health. These options involve engagement and intervention, distinguishing them from the inaction that characterizes nonfeasance. Therefore, the answer that best aligns with the concept of nonfeasance in a public health context is the choice that involves ignoring a known health hazard.
