NRS 636-Chapter 06: Understanding and Critically Appraising the Literature Review Grove: Understanding Nursing Research, 7th Edition MULTIPLE CHOICE 1. One reason for conducting a review of the literature other than for purposes of developing a research study is to a. determine the expertise of researchers in the field of study. b. identify current theoretical frameworks. c. implement evidence-based practice guidelines. d. work in a Magnet-certified hospital setting. ANS: C Although a literature reviews are commonly associated with development of research studies, they are also conducted when developing projects to establish evidence-based practice (EBP). Evaluation of the expertise of researchers and identification of theoretical frameworks are part of literature reviews but are not the reason for conducting them. Nurses in Magnet hospitals often participate in EBP projects and will conduct literature reviews for these, but not solely to be able to work in these institutions. DIF: Cognitive level: Applying (Application) 2. What is the purpose of a limited research review? a. To allow the reader to become familiar with the research problem b. To develop an initial pilot study prior to a more in-depth study c. To direct the planning and execution of a study d. To identify studies published after a study is performed ANS: D A limited research review is often conducted after an initial literature review to describe any studies performed after the study has been performed. The results of both the original literature review and the limited literature review are included in the report. A full literature review allows the reader to become familiar with the research problem and is performed prior to a pilot or a full study. The full literature review directs the planning and execution of the study. DIF: Cognitive level: Understanding (Comprehension) 3. A reviewer reading a proposal for a qualitative research study notes that the author has not included a literature review. The reviewer understands that a literature review may have been omitted in this case because a. it is not necessary to conduct a literature review for qualitative research. b. qualitative research is conducted to study areas where there is no previous knowledge. c. some researchers feel that previous studies may bias data collection in qualitative studies. d. the researcher was not adequately prepared to conduct this research study. ANS: C NURSINGTB.COM Understanding Nursing Research 7th Edition Grove Test Bank NU RS IN GT B.CO M Many times, literature reviews are omitted from qualitative research to avoid causing expectations that might bias findings, data collection, and data analysis. A literature review can be helpful in qualitative research and should be performed if possible. This is true of some but not all qualitative methods (e.g., grounded theory); however, it is not true of all qualitative designs. At times, there is little or no previous research on the topic, but not always. Omission of a literature review in qualitative research does not indicate that the researcher is ill-prepared. DIF: Cognitive level: Applying (Application) 4. Which type of study is least likely to include a review of the literature prior to initiating the study? a. Grounded theory b. Phenomenological c. Qualitative d. Quantitative ANS: B Phenomenological researchers are most likely to delay literature review until after a study is completed to avoid bias. Grounded theory researchers may have a limited review of relevant studies to make the researcher aware of what studies have been conducted and that a research problem exists. Qualitative and quantitative research will involve literature reviews, although these may be less substantial in qualitative studies. DIF: Cognitive level: Remembering (Knowledge) 5. What is the main purpose of a literature review in grounded theory research? a. To explain, extend, and support the framework used for the study b. To identify gaps in current knowledge about the research topic c. To place research findings in context of what is already known d. To support the need to study the selected research topic ANS: A In grounded theory research, the researcher uses the literature review primarily to explain, support, and extend the framework used in the study, and not to direct data collection or study methods. It is usually completed at the end of the analysis rather than before the proposal development. The literature review in quantitative studies is designed to identify gaps in knowledge. Phenomenological literature reviews are conducted to place research findings in the context of what is already known. Because the literature review for grounded theory research is generally conducted at the end of the analysis, it is not used to support the need for studying the topic, but to summarize what is known. DIF: Cognitive level: Understanding (Comprehension) 6. Which type of information would the reader be least interested in obtaining from a literature review? a. How the variables of interest have been operationally defined in prior studies. b. Narration of an author’s impression of a given situation c. Research results d. What research approaches have been used to study similar problems. NURSINGTB.COM Understanding Nursing Research 7th Edition Grove Test Bank NU RS IN GT B.CO M ANS: B The type of information that the reader would be least interested in obtaining from a literature review is the narration of an author’s impression of a given situation. A high-quality review of literature contains the current theoretical and scientific knowledge about a specific topic, and identifies what is known and unknown about that topic. A review of literature is the process of finding relevant research reports and theoretical sources, critically appraising these sources, synthesizing the results, and developing an accurate complete reference list. DIF: Cognitive level: Understanding (Comprehension) 7. Why might Wikipedia be a questionable reference for a study citation? a. It does not contain factual information. b. It does not provide ideas for other resources. c. It is an online resource. d. It is an open,
