Answer to Question 1

Correct Answer: 4

For many diseases, the potential consequences of a single disease episode on the individual and society make prevention desirable, especially for highly contagious diseases that are capable of causing epidemics. In these instances, immunization provides artificially acquired immunity. The purpose of vaccination is to establish adequate levels of antibody or memory cells to provide effective immunity. Healthier children are not the result of reduced immunization. The lack of immunization will not impact the number of colds and flu outbreaks in a school system. High rates of illness may increase school costs.

Answer to Question 2

Correct Answer: 4

Skin testing can assess cell-mediated immunity. A known antigen is injected intradermally. The site is then observed for induration and erythema, which typically peak at 24 to 48 hours. An induration of at least 10 mm in diameter is a positive reaction that indicates previous exposure and sensitization to the antigen. Itching is not a sign of exposure to an antigen.
