Chapter 05: Evidence-Based Practice Chapter 05: Evidence-Based Practice Potter et al.: Fundamentals of Nursing, 9th Edition MULTIPLE CHOICE 1. A nurse uses evidence-based practice (EBP) to provide nursing care. What is the best rationale for the nurse’s behavior?

a.

EBP is a guide for nurses in making clinical decisions.

b.

EBP is based on the latest textbook information.

c.

EBP is easily attained at the bedside.

d.

EBP is always right for all situations.

ANS: A Evidence-based practice (EBP) is a guide for nurses to structure how to make appropriate, timely, and e฀洅ective clinical decisions. A textbook relies on the scienti฀฀c literature, which may be outdated by the time the book is published. Unfortunately, much of the best evidence never reaches the bedside. EBP is not to be blindly applied without using good judgment and critical thinking skills. DIF:Understand (comprehension)REF:52 OBJ: Discuss the bene฀฀ts of evidence-based practice.

2. In caring for patients, what must the nurse remember about evidence-based practice (EBP)?

a.

EBP is the only valid source of knowledge that should be used.

b.

EBP is secondary to traditional or convenient care knowledge.

c.

EBP is dependent on patient values and expectations.

d.

EBP is not shown to provide better patient outcomes.

ANS: C Even when the best evidence available is used, application and outcomes will di฀洅er based on patient values, preferences, concerns, and/or expectations. Nurses often care for patients on the basis of tradition or convenience. Although these sources have value, it is important to learn to rely more on research evidence than on nonresearch evidence. Evidence-based care improves quality, safety, patient outcomes, and nurse satisfaction while reducing costs. DIF:Understand (comprehension)REF:53 OBJ: Discuss the bene฀฀ts of evidence-based practice. TOP: Implementation MSC:Management of Care 3. A nurse wants to change a patient procedure. Which action will the nurse take to easily ฀฀nd research evidence to support this change?

a.

Read all the articles found on the Internet.

b.

Make a general search of the Internet.

c.

Use a PICOT format for the search.

d.

Start with a broad question.

ANS: C http://boostgrade.info/chapter05evidencebasedpractice/

Chapter05:EvidenceBasedPractice|NursingTestBanks

The more focused the question is, the easier it becomes to search for evidence in the scienti฀฀c literature. The PICO format allows the nurse to ask focused questions that are intervention based. Inappropriately formed questions (general search or broad question) will likely lead to irrelevant sources of information. It is not bene฀฀cial to read hundreds of articles. It is more bene฀฀cial to read the best four to six articles that speci฀฀cally address the question. DIF:Apply (application)REF:54 OBJ: Describe the steps of evidence-based practice. TOP: Implementation MSC:Management of Care 4. A nurse has collected several research ฀฀ndings for evidence-based practice. Which article will be the best for the nurse to use?

a.

An article that uses randomized controlled trials (RCT)

b.

An article that is an opinion of expert committees

c.

An article that uses qualitative research

d.

An article that is peer-reviewed

ANS: A Individual RCTs are the highest level of evidence or “gold standard” for research. A peer-reviewed article means that a panel of experts has reviewed the article; this is not a research method. Qualitative research is valuable in identifying information about how patients cope with or manage various health problems and their perceptions of illness. It does not usually have the robustness of an RCT. Expert opinion is on the bottom of the hierarchical pyramid of evidence. DIF:Understand (comprehension)REF:55-56 OBJ: Explain the levels of evidence available in the literature. TOP: Assessment MSC:Management of Care 5. The nurse is reviewing a research article on a patient care topic. Which area should entice the nurse to read the article?

The Agency for Healthcare Research and Quality (AHRQ) includes clinical guidelines and evidence summaries. MEDLINE includes studies in medicine, nursing, dentistry, psychiatry, veterinary medicine, and allied health. EMBASE includes biomedical and pharmaceutical studies. PsycINFO deals with psychology and related health care disciplines. DIF:Apply (application)REF:55 OBJ: Describe the steps of evidence-based practice. TOP: Implementation MSC:Management of Care 7. A nurse writes the following PICOT question: How do patients with breast cancer rate their quality of life? How should the nurse evaluate this question?

a.

A true PICOT question regardless of the number of elements

b.

A true PICOT question because the intervention comes before the control

c.

Not a true PICOT question because the comparison comes after the intervention

d.

Not a true PICOT question because the time is not designated

ANS: A A meaningful PICOT question can contain only a P and O: How do patients with breast cancer (P) rate their quality of life (O)? Note that a well-designed PICOT question does not have to follow the sequence of P, I, C, O, and T. The aim is to ask a question that contains as many of the PICOT elements as possible. DIF: Analyze (analysis) REF: 54 OBJ: Develop a PICOT question. TOP:EvaluationMSC:Management of Care 8. A nurse is reviewing literature for an evidence-based practice study. Which study should the nurse use for the most reliable level of evidence that uses statistics to show e฀洅ectiveness?

a.

Meta-analysis

b.

Systematic review

c.

Single random controlled trial

d.

Control trial without randomization

ANS: A The main di฀洅erence is that in a meta-analysis the researcher uses statistics to show the e฀洅ect of an intervention on an outcome. In a systematic review no statistics are used to draw conclusions about the evidence. A single random controlled trial (RCT) is not as conclusive as a review of several RCTs on the same question. Control trials without randomization may involve bias in how the study is conducted. DIF:Analyze (analysis)REF:55 OBJ: Explain the levels of evidence available in the literature. TOP: Planning MSC:Management of Care 9. A nurse is reviewing research studies for evidence-based practice. Which article should the nurse use for qualitative nursing research?

a.

An article about the number of falls after use of no side rails

b.

An article about infection rates after use of a new wound dressing

c.

An article about the percentage of new admissions on a new ฀฀oor

d.

An article about emotional needs of dying patients and their families

ANS: D Studying emotional needs is a qualitative study. Qualitative nursing research is the study of phenomena that are di฀甇cult to quantify or categorize, such as patients’ perceptions of illness. The number of falls, infection rates, and percentages of new admissions are all examples of quantitative research.

MSC:Management of Care 10. A nurse develops the following PICOT question: Do patients who listen to music achieve better control of their anxiety and pain after surgery when compared with patients who receive standard nursing care following surgery? Which information will the nurse use as the “C”?

a.

After surgery

b.

Who listen to music

c.

Who receive standard nursing care

d.

Achieve better control of their anxiety and pain

ANS: C Do patients (P) who listen to music (I) achieve better control of their anxiety and pain (O) after surgery (T) when compared with patients who receive standard nursing care following surgery (C)? DIF: Understand (comprehension) REF: 54 OBJ: Develop a PICOT question. TOP:ImplementationMSC:Management of Care 11. The nurse uses a PICOT question to develop an evidence-based change in protocol for a certain nursing procedure. However, to make these changes throughout the entire institution would require more evidence than is available at this time. What is the nurse’s best option?

a.

Conduct a pilot study to investigate ฀฀ndings.

b.

Drop the idea of making the change at this time.

c.

Insist that management hire the needed sta฀洅 to facilitate the change.

d.

Seek employment in another institution that may have the sta฀洅 needed.

ANS: A http://boostgrade.info/chapter05evidencebasedpractice/

Chapter05:EvidenceBasedPractice|NursingTestBanks

When evidence is not strong enough to apply in practice, the next option is to conduct a pilot study to investigate the PICOT question. Dropping the idea would be counterproductive; insisting that management hire sta฀洅 could be seen as a mandate and could produce negative results. Seeking employment at another institution most likely would not be the answer because most institutions operate under similar established guidelines.

The nurse is trying to identify common general themes relative to the e฀洅ectiveness of cardiac rehabilitation from patients who have had heart attacks and have gone through cardiac rehabilitation programs. The nurse conducts interviews and focus groups. Which type of research is the nurse conducting?

a.

Nonexperimental research

b.

Experimental research

c.

Qualitative research

d.

Evaluation research

ANS: C Qualitative research involves using inductive reasoning to develop generalizations or theories from speci฀฀c observations or interviews. Evaluation and experimental research are forms of quantitative research. Nonexperimental descriptive studies describe, explain, or predict phenomena such as factors that lead to an adolescent’s decision to smoke cigarettes. DIF:Analyze (analysis)REF:60 OBJ: Explain how nursing research improves nursing practice. TOP: Implementation MSC:Management of Care 13. In conducting a research study, the nurse researcher guarantees the subject no information will be reported in any manner that will identify the subject and only the research team will have access to the information.

a.

Bias

b.

Con฀฀dentiality

c.

Informed consent

d.

The research process

ANS: B Con฀฀dentiality guarantees that any information the subject provides will not be reported in any manner that identi฀฀es the subject and will not be accessible to people outside the research team. Biases are opinions that may in฀฀uence the results of research. Informed consent means that research subjects (1) are given full and complete information about the purpose of the study, procedures, data collection, potential harm and bene฀฀ts, and alternative methods of treatment; (2) are capable of fully understanding the research; (3) have the power to voluntarily consent or decline participation; and (4) understand how con฀฀dentiality or anonymity is maintained. The research process is a broader concept that provides an orderly series of steps that allow the researcher to move from asking a question to ฀฀nding the answer.

ANS: B During results or conclusions, the researcher interprets the ฀฀ndings of the study, including limitations. An abstract summarizes the purpose of the article with major ฀฀ndings. Study design involves selection of research methods and type of study conducted. The researcher explains how to apply ฀฀ndings in a practice setting for the type of subjects studied in the clinical implications section.

After reviewing the literature, a strategy is implemented on the unit. After 3 months, the nurse ฀฀nds that the falls have decreased. Which process did the nurse institute?

a.

Performance improvement

b.

Peer-reviewed project

c.

Generalizability study

d.

Qualitative research

ANS: A Performance improvement focuses on performance issues like falls or pressure ulcer incidence. A peerreviewed article is reviewed for accuracy, validity, and rigor and approved for publication by experts before it is published. Generalizability is not a study/research; it is if the results of a study can be compared to other patients with similar experiences. This is a quantitative study, not a qualitative study.

a.

Analyze results.

b.

Conduct the study.

c.

Determine method.

d.

Develop a hypothesis.

ANS: D After identifying an area of interest or clinical problem, the steps of the research process are as follows: Develop research question(s)/hypotheses; determine how the study will be conducted; conduct the study; and analyze results of the study.

After reviewing the literature, the evidence-based practice committee institutes a practice change that bedrails should be left in the down position and hourly nursing rounds should be conducted. The results indicate over a 40% reduction in falls. What is the committee’s next step?

a.

Evaluate the changes in 1 month.

b.

Implement the changes as a pilot study.

c.

Wait a month before implementing the changes.

d.

Communicate to sta฀洅 the results of this project.

The last step of evidence-based practice (EBP) is to share the outcomes of EBP changes with others. Changes must be evaluated before the outcomes are shared. Once communicated, changes should be put in place as the committee deems reasonable (i.e., either hospital wide or as a pilot study). Waiting should not be an option unless the results are not to the committee’s liking. DIF:Apply (application)REF:57 OBJ: Discuss ways to apply evidence in practice. TOP: Implementation MSC:Management of Care 18. A nurse is developing a care delivery outcomes research project. Which population will the nurse study?

a.

Nurses

b.

Patients

c.

Administrators

d.

Health care providers

ANS: B Similar to the expected outcomes you develop in a plan of care, a care delivery outcome focuses on the recipients of service (e.g., patient, family, or community) and not the providers (e.g., nurse or physician/health care provider). Administrators are not recipients of service. DIF:Understand (comprehension)REF:58 OBJ: Explain how nursing research improves nursing practice. TOP: Implementation MSC:Management of Care 19. A nurse is implementing an evidence-based practice project regarding infection rates. After reviewing research literature, which other evidence should the nurse review?

a.

Quality improvement data

b.

Inductive reasoning data
