1. Eradication
2. Incubation
3. Immunity
4. Vaccination
Correct Answer: 4
Rationale 1: Eradication is the removal of disease.
Rationale 2: Incubation is the time it takes for the body to process the antigen and mount an effective response.
Rationale 3: Immunity is the body's ability to resist disease.
Rationale 4: Vaccination is the process of introducing something foreign into the body to trigger immune activation before the client is exposed to the real pathogen.
Global Rationale: Vaccination is the process of introducing foreign proteins or inactive cells (vaccines) into the body to trigger immune activation before the patient is exposed to the real pathogen. As a result of the vaccination, memory B cells or T cells are formed. When later exposed to the real infectious organism, these cells will react quickly by producing large quantities of antibodies and cytokines that help to neutralize or destroy the antigen. Eradication is the removal of disease. Incubation is the time it takes for the body to process the antigen and mount an effective response. Immunity is the body's ability to resist disease.
