Final answer:
Volunteering in influenza injection clinics as a form of health promotion and preventive care is an example of primary prevention. The correct answer is option A.
Step-by-step explanation:
When nurses volunteer to participate in influenza injection clinics, they are engaging in a form of health promotion and preventive care known as primary prevention. Primary prevention aims to prevent disease or injury before it ever occurs. This is done by preventing exposures to hazards that cause disease or injury.
Altering unhealthy or unsafe behaviors that can lead to disease or injury, and increasing resistance to disease or injury should exposure occur. Volunteer nurses providing flu vaccines work to increase resistance to influenza by boosting community immunity through vaccination.
Vaccination is a cornerstone of public health and can be thought of in terms of evolution. Each year, scientists and health experts recommend specific vaccinations based on the predicted strains of the flu virus. By artificially stimulating the adaptive immune defenses, a vaccine triggers memory cell production.
