Answer to Question 2
A
Developing the clinical question is the most important step in the evidence-based process. The RN must develop a clinical question that encompasses the key components to ensure that the question addresses an answerable concern that can be converted into relevant application. Evi-dence-based practice requires that clinicians make use of the best research they can find to help them in decision making. To find that research efficiently, the clinician must ask a well-designed clinical question with all the elements that will lead to finding relevant research literature. The first step in doing this is to determine the type of question: background or foreground. The type of question helps determine the resources to access to answer the question.
