Answer to Question 1

ANS: A, B, D
There are six criteria for assuming possible causation including strength of the association, dose-response relationship, temporally correct relationship, biological plausibility, consistency among studies, and specificity. Only the easy-to-understand, consistent research studies and the increased dose leading to increased illness are consistent with those six criteria.

Answer to Question 2

ANS: A, B, D
The models are very useful in relation to changing individual behaviors, but they do not address the complex relationships among social, structural, and physical factors in the environment, such as lack of social support systems or inaccessible health services. Changes are needed to improve care for socially and politically disenfranchised groups. Knowledge is always within a social context and is always bound to power relationships. A nurse cannot assign power and control to an individual. The individual must take on power, although perhaps with the nurse's guidance.
