[futuristic]

How does quantitative research contribute to evidence-based practice? (Select all that apply.)
 
  a. It provides facts that nurses can add to their knowledge base. This makes practice more objective and quantifiable.
  b. It provides scientific support for policies already in place. More evidence makes an existent policy more defensible.
  c. It provides evidence opposing policies already in place. Evidence in opposition to policies may result in new policies.
  d. It allows the nurse to understand the personal experience of illness and the meaning the client attaches to it. This engenders compassion.
  e. It contributes evidence that will make nursing practice almost completely evidence-based, eliminating different styles of nursing practice.

Question 2

What does appropriate generalization require? (Select all that apply.)
 
  a. Any type of sample, whether or not it is representative
  b. Application of findings to the population from which the sample was drawn
  c. More than one research study using the same research questions and variables
  d. Statistically significant findings
  e. Non-significant findings that are supported by several related studies

Answer to Question 1

ANS: B, C
Quantitative research is a formal, objective, systematic process in which numerical data are used to obtain information about the world. This research method is used to describe variables, examine relationships among variables, and determine cause-and-effect interactions between variables. The qualitative research method of phenomenology allows understanding of the lived experience and the meaning it engenders. The aim of phenomenology is to explore an experience as it is lived by the study participants and interpreted by the researcher. Evidence-based practice is the conscientious integration of best research evidence with clinical expertise and patient values and needs in the delivery of quality, cost-effective health care. It provides the basis for policy decisions and for voluntary change in individual nursing practice. Nursing style is a matter of personal choice.

Answer to Question 2

ANS: B, C, D
Generalization involves the application of trends or general tendencies (which are identified by studying a sample) to the population from which the research sample was drawn. Researchers must be cautious in making generalizations, because a sound generalization requires the support of many studies with a variety of samples.
