Which statement about using objective data for screening and prevention is true?

• A. Objective data cannot identify risk factors.
• B. Objective data is only used after symptoms appear.
• C. Objective data can identify risks before symptoms appear, enabling preventive strategies.
• D. Objective data is not helpful in prevention.

Answer: (C)

Objective data used in screening and prevention means relying on measured, observable information to find risk factors or early signs before anyone feels ill. This approach allows you to identify who is at risk and take preventive actions before symptoms develop. For example, a routine lipid panel can reveal high cholesterol that raises heart disease risk, prompting lifestyle changes or medications to prevent heart events. Blood pressure readings can uncover hypertension before it causes symptoms, enabling interventions to reduce cardiovascular risk. Screenings like mammography or colonoscopy can detect preclinical disease or precancerous changes, guiding early prevention or treatment. Because of this, the statement that objective data can identify risks before symptoms appear, enabling preventive strategies, is true. In contrast, saying objective data cannot identify risk factors, or that it’s only used after symptoms appear, or that it isn’t helpful for prevention, misrepresents how screening and preventive care work.
