NCLEX Community Health Nursing Practice Test

The main idea here is how different levels of prevention work in public health. A clinic that focuses on health education and immunizations aims to prevent disease before it starts. Vaccinations stop illnesses from taking hold and protect the community, and education helps people adopt behaviors that reduce risk. Since these actions occur before disease occurs, they are primary prevention.

Secondary prevention would involve screening to detect diseases early so they can be treated sooner, not preventing the disease in the first place. Tertiary prevention focuses on reducing complications or disability after a disease has already developed. Diagnosis and prompt intervention typically describe identifying and treating disease that is already present, which is not prevention at the outset.
