• Exposure, Acute, Chronic, Terminal

Which of the following occurs during the prepathogenesis stage?

• Early symptoms appear

• Host-agent interaction occurs without clinical signs

• Diagnosis is established

• Death is imminent

Primary prevention focuses on:

• Early diagnosis and treatment

• Rehabilitation

• Promoting health and preventing disease before it occurs

• Reducing complications of disease

What is the goal of secondary prevention?

• Disease eradication

• Screening and early treatment to halt disease progression

• Alleviation of symptoms

• Immunization and health education

Tertiary prevention aims to:

• Reduce the impact of disease and improve quality of life

• Stop disease occurrence

• Delay onset of complications

• Promote mental health

What is an example of a primary preventive measure?

• Chemotherapy

• Use of seat belts

• Blood glucose monitoring

• Surgery for cancer removal

Administering insulin to a diabetic patient is an example of:

• Primary prevention

• Tertiary prevention

• Pathogenesis stage intervention

Which level of prevention is best described by routine health check-ups?

• Primary

• Secondary

• None of the above

The application of vaccines is an example of:

• Primary prevention

• Secondary prevention

• Tertiary prevention

In the natural history of disease, the 'iceberg phenomenon' highlights:

• Visible signs of disease represent a fraction of the total disease burden

• All disease manifestations are above the surface

• Rehabilitation efforts post-disease

• Host susceptibility in clinical cases
