An example of tertiary prevention would be

• A. Vaccination to prevent disease.
• B. Regular screening to detect disease early.
• C. Use of assistive devices to manage disability.
• D. Improving diet to reduce risk factors.

Answer: (C)

Tertiary prevention aims to minimize the impact of an established health condition by reducing impairment and disability and helping the person regain or maintain function. Using assistive devices to manage disability fits this idea because, after a disability has occurred, these tools (like walkers, canes, prosthetics, or wheelchairs) help the individual function more independently, prevent secondary complications, and participate in daily activities.

Vaccination to prevent disease is a primary prevention activity, aiming to stop disease from occurring in the first place. Regular screening to detect disease early is secondary prevention, focused on early detection to improve outcomes. Improving diet to reduce risk factors is also a primary prevention strategy, targeting prevention before illness develops.
