NURSING RESEARCH METHODS AND CRITICAL APPRAISAL FOR EVIDENCE-BASED PRACTICE 8TH EDITION TEST BANK WITH ALL CHAPTERS.

Chapter 03: Gathering and Appraising the Literature Test Bank MULTIPLE CHOICE 1. The review of literature is important to the research process for which of these reasons? a. It guides all steps of the research process. b. It provides a vehicle to disseminate the findings of the study. c. It guides only the conceptualization of the problem statement. d. It identifies only gaps or inconsistencies in the knowledge base. ANS: A Feedback A The review of the literature is important throughout all stages of a research study. B A completed study may be published to disseminate the findings of a study and thus become one citation in a literature review for future studies. However, the literature review does not ensure this. C The review of the literature guides the problem statement as it is defined along with all other parts and stages of a research study. D The review of the literature contributes to consistencies in the literature, locates instruments used to measure variables, identifies experts on topics, etc. DIF: Cognitive Level: Understanding (Comprehension) REF: Page 50 2. The “6S” pyramid hierarchy of preappraised evidence developed by DiCenso, Bayley, & Haynes (2009) provides a means to help nurse consumers of research find preappraised evidence for clinical questions. Using this model, which level of evidence would be highest? a. Summaries such as clinical practice guidelines b. Synopsis of Synthesis such as summaries found in the journal Evidence-Based Nursing c. Syntheses or systematic reviews such as a Cochrane review d. Studies such as synopses of a single study ANS: A Feedback A The highest level of those presented in the question is Summaries, which include clinical practice guidelines and electronic evidence-based textbooks. These summaries about specific conditions are updated regularly. An even higher level of the 6S pyramid is Computerized Decision Support Systems (CDSS), which integrate evidence-based clinical information into an electronic medical record. At present, these systems are not a reality in most institutions and, therefore, they were not included as an option in this question. B Next highest is Synopsis of Synthesis, which provides a preappraised summary of a systematic review that can be found in journals, such as Evidence-Based Nursing. C Third highest is Syntheses or systematic reviews such as a Cochrane review. D Lowest in the hierarchy is Studies, which often refer to synopses of single studies evaluated by a single expert. DIF: Cognitive Level: Understanding (Comprehension) REF: Page 55-57 3. For which of these reasons would a nurse researcher include refereed journals in the literature review? a. The articles are critiqued by a panel of external reviewers. b. The articles selected for publication are related to a specific field of knowledge. c. The journals encourage competition among authors to have their articles published. d. The journals publish only articles that are primary sources of research findings. ANS: A Feedback A The articles are critiqued by a panel of external expert readers. B Articles selected for publication are sources of the latest information about a great variety of fields of knowledge. C There is no overt competition among authors because refereed journals have blinded reviews in most cases. D Refereed journals are often the first source of primary research findings, but they may also include other types of research articles. DIF: Cognitive Level: Understanding (Comprehension) REF: Page 60 4. A research article has undergone a blind review for a peer-reviewed journal. The nurse reading the research article should understand which of the following about this review process? a. The reviewers of the article did not know the identity of the other reviewers. b. The reviewers of the article did not know the identity of the author. c. The criteria used to review the article were not known to the author. d. The criteria used to review the article were determined by the reviewers. ANS: B Feedback A The reviewers of the article may or may not know the identity of the other reviewers. B In a blind review, the manuscript to be reviewed does not include the name of the author. C A standard set of scholarly criteria is used to review the article.

DIF: Cognitive Level: Understanding (Comprehension) REF: Page 60 5. For which of these reasons would a nurse researcher decide to use secondary sources in a review of the literature? a. They provide material written by the person who conducted the study. b. They provide a different way of looking at specific issues or problems. c. They define the relationship of two or more variables affecting an outcome. d. They supplement the body of nursing knowledge in a specific area of practice. ANS: D Feedback A Secondary sources are authored by an individual other than the researcher who conducted the study. B The evidence is distilled by an expert and usually provides a critical evaluation or response to a study, not necessarily a different way of looking at specific issues or problems. C The relationship of two or more variables affecting an outcome defines a hypothesis. D Secondary sources published in refereed journals usually include implications for practice and the work’s contributions to the development of nursing science.

At least the last 6 months to 2 years b. At least the past 3 to 5 years c. At least the past 6 to 10 years d. At least the past 12 to 15 years ANS: B Feedback A The most recent 6 months to 2 years is an insufficient timeline for an academic paper or project. B The past 3 to 5 years is a sufficient timeline for an academic paper or project because recent literature is relevant and may include classic references in reference lists. C Six to 10 years is probably longer than the timeline needed for the search. D Twelve to 15 years is likely to be much longer than the timeline needed for the search. DIF: Cognitive Level: Understanding (Comprehension) REF: Page 64 11. A nurse is encouraged to use a Boolean operator to more efficiently perform an electronic search of the literature.

A clinical query that can be performed to focus on a particular clinical issue or practice question ANS: C Feedback A Although reference librarians can be helpful for electronic database searches, they are not Boolean operators. B A Boolean operator is not a software program but refers to variables that define an electronic database search. C A Boolean operator defines the relationships between words or groups of words in the literature search. These include the words, “and,” “or,” and “not.” D A Boolean operator is not a query for a clinical issue or practice question. DIF: Cognitive Level: Understanding (Comprehension) REF: Page 68 12.

D Although both quantitative and qualitative sources may be used, it is not necessary to include both in a review of the literature. DIF: Cognitive Level: Understanding (Comprehension) REF: Table 3-1 15. Which objective of a review of the literature is unique to a review for research purposes, rather than a review for evidence-based practice? a. Discover conceptual frameworks used to examine problems b. Generate useful research questions and hypotheses c. Determine what is unknown about a subject, as well as what requires clarification d. Uncover a new practice intervention or gain support for current interventions and policies ANS: B Feedback A Conceptual frameworks are useful for both formal research and evidence-based practice. B For research purposes, the literature review focuses the study by discovering gaps or conflicts in the literature and identifying areas where little research evidence exists. This helps define the research questions and hypotheses. C Both formal research and evidence-based practice are concerned with what is known about a subject, as well as what requires clarification. D Uncovering new practice interventions or gaining support for current practices is primarily in the realm of evidence-based practice. 16.
