Which statement best defines primary prevention?

• A. Tx and management of the patient's clinical and chronic disease.
• B. Identification and Tx as asymptomatic persons who have developed risk factors.
• C. A set of actions that prevents a specific disease or condition before it can occur.
• D. Health promotion through education.

Answer: (C)

Primary prevention means taking action to stop a disease from ever developing by removing risk factors or providing protection before any disease occurs. This definition fits best because it explicitly describes preventing onset, not treating it or detecting it after it has begun. Think of vaccines, safety measures like seat belts, and interventions that reduce risk factors before illness appears.

The other statements describe actions taken after disease is present or focused on identifying risk factors for early detection or education, which are not the defining feature of primary prevention.
