Answer to Question 1

ANS: D
Theories are tested through research to determine the correctness of their descriptions, explanations, predictions, and strategies to control outcomes.
In this situation the theory is already developed. The correct answer is Strategies for controlling outcomes. Theories are tested through research to determine the correctness of their descriptions, explanations, predictions, and strategies to control outcomes.
The theory being tested will not explain why the situation happens. The correct answer is Strategies for controlling outcomes. Theories are tested through research to determine the correctness of their descriptions, explanations, predictions, and strategies to control outcomes.
Prediction requires formal experimental study. The correct answer is Strategies for controlling outcomes. Theories are tested through research to determine the correctness of their descriptions, explanations, predictions, and strategies to control outcomes.

Answer to Question 2

ANS: D
Meta-analysis goes beyond the review by performing statistical analyses with combined data. Reading and evaluating meta-analyses assist the practicing nurse in learning the latest evidence-based practices for a given clinical problem.
Writing a critique of the available literature is conducting a literature review. Not all literature will be helpful in learning best practices for clinical problems.
Expert opinion papers do not necessarily discuss or provide evidence for best practices.
Writing a summary of the literature review may be very helpful, but it would be the review itself, not the actual writing of the review, that would be helpful.
