Answer to Question 1
ANS: C
Hospital surveillance is used to improve quality of care and outcomes. An example is an infection that occurs in patients who had procedures at that facility. Reduction of the incidence of venti-lator-acquired pneumonia is one reason why a hospital uses surveillance, but it does not address the entire issue. Hospital surveillance is unable to eliminate pathogens from the environment and cannot protect the public against isolated patients.
Answer to Question 2
ANS: B
Disease surveillance helps establish baseline rates of disease occurrence and patterns of spread to make it possible to initiate a rapid response to an outbreak. Disease surveillance is unable to erad-icate a disease before it starts, to target populations for triage, or to reduce the incidence of heart disease in a community. However, disease surveillance does make it possible to initiate a rapid response to an outbreak of a disease or an event that can cause a health problem.
