Answer to Question 1

ANS: C
The epidemiologic triangle consists of an agent (chemical), host (community consisting of several variants), and environment (air, water, soil, etc.). The other examples do not contain an agent, host, and environment.

Answer to Question 2

ANS: B
The use of a GIS allows the PHN to apply the principles of epidemiology into practice. GIS al-lows nurses to code data so that it is related spatially to a place on earth and is helpful in deter-mining concentrated areas for incidence of disease and illness. An electronic health record (EHR) would be the most appropriate place to record client data from a foot clinic. Evaluation of effec-tiveness of a farm safety program would need to be done through some type of assessment or evaluation methodGIS would not be useful to collect this data. GIS is not a scheduling system and would not be helpful when scheduling health promotion programs in the community.
