Age-Adjusted Death Rates Quiz

The age-adjusted death rate shows what the level of mortality would be if there were no changes in the age composition of the population from year to year. It is a better indicator than the unadjusted rate of change over time in the risk of dying because it accounts for changes in the age distribution of the population.

Antisepsis refers to the application of chemical agents to living tissue to kill or control microorganisms. It is used to prevent infection and reduce the risk of microbial contamination in medical settings, such as during surgeries or wound care.

Antigens are foreign substances that induce the formation of antibodies. In some vaccines, the antigen is highly defined, such as in pneumococcal polysaccharide, hepatitis B surface antigen, tetanus, or diphtheria toxoids. In other cases, the antigen is complex or incompletely defined, as in killed pertussis bacteria or live, attenuated viruses.
