Essentials of Nursing Research Appraising Evidence for Nursing Practice 10th Edition Polit Test Bank

CHAPTER 1 1. Which of the following groups would be best served by the development of a scientific base for nursing practice? A) Nursing administrators B) Practicing nurses C) Nurses' clients D) Health care policymakers Ans: C Feedback: Nursing research is systematic inquiry designed to develop trustworthy evidence about issues of importance to nurses and their clients. Nurse leaders recognize the need to base specific nursing decisions on evidence indicating that the decisions are clinically appropriate, cost-effective, and result in positive client outcomes. Although all of the people listed would benefit from the development of a scientific base for nursing practice, ultimately it is the clients themselves who would most benefit, as they would then receive the most appropriate and most effective care. 2. An especially important goal for the nursing profession is to do which of the following? A) Conduct research to better understand the context of nursing practice B) Establish a solid base of evidence for practice through disciplined research C) Document the role nursing serves in society D) Establish research priorities Ans: B Feedback: Nurses are increasingly expected to understand and undertake research and to base their practice on evidence from research. Evidence-based practice is the use of the best evidence in making patient care decisions and typically comes from research conducted by nurses and other health-care professionals. All of the other answers are possible goals for the nursing profession, but none is as important as establishing evidence for practice. 3. Which of the following is a fundamental belief of those who hold to the constructivist paradigm? A) A fixed reality exists in nature for humans to understand B) The nature of reality has changed over time C) Reality is multiply constructed and multiply interpreted by humans D) Reality cannot be studied empirically Ans: C Feedback: In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds, and thus “truth” is a composite of multiple constructions Page 2 of reality. However, constructivists do believe that reality can be studied empirically. Belief in a fixed reality that exists in nature for humans to understand would be an example of a positivist belief, not a constructivist one. The constructivist belief does not hold so much that the nature of reality has changed over time as that it has always been constructed by human minds. Page 3 4. Which of the following is a fundamental belief of those who hold to the positivist paradigm? A) The researcher is objective and independent of those being studied B) The researcher cannot interact with those being studied C) The researcher instructs those being studied to be objective in providing information D) The distance between the researcher and those being researched is minimized to enhance the interactive process Ans: A Feedback: In the positivist paradigm, it is assumed that there is an objective reality and that natural phenomena are regular and orderly. In the constructivist paradigm, it is assumed that reality is not a fixed entity but is rather a construction of human minds, and thus “truth” is a composite ...
