Accepted Answer

According to Melnyk and Fineout-Overholt et al.,the first step is step 0: Cultivating a spirit of inquiry.Integrating evidence with clinical expertise is step 4.Asking clinical questions is step 1.Searching for the best evidence is step 2.

Question 2

The term evidence-based was first used in:&#10;A) Canada.&#10;B) Great Britain.&#10;C) the United States.&#10;D) Australia.

Accepted Answer

The term evidence-based was first attributed to Gordon Gyatt,a Canadian physician at McMaster University in 1992.Great Britain,the United States,and Australia did not use this term before it was used in Canada.

Question 3

A summary of the research evidence that relates to a specific question and to the effects of an intervention is:&#10;A) evidence-based practice.&#10;B) meta-analysis.&#10;C) systematic review.&#10;D) narrative review.

Accepted Answer

A systematic review is a summary of the research evidence that relates to a specific question and to the effects of an intervention.Evidence-based practice includes the best available evidence from a variety of sources,including research studies,nursing experience and expertise,and community leaders.Meta-analysis is a specific method of statistical synthesis used in some systematic reviews,where the results from several studies are quantitatively combined and summarized.A narrative review is a review done on published papers that support the reviewer's particular point of view or opinion and is used to provide a general discussion of the topic reviewed.

Question 4

A nurse is reading a systematic review when researching the best practices to promote increased safety among toddlers.Which of the following information would the nurse most likely find?&#10;A) Results of randomized controlled trials&#10;B) A description of the methods used to search for evidence&#10;C) Data compiled on a particular question&#10;D) An in-depth review of the literature completed by one person

Accepted Answer

A systematic review is usually done by more than one person and describes the methods used to search for the evidence.It is a method of identifying,appraising,and synthesizing research evidence to evaluate and interpret all available research relevant to a particular research question.

Question 5

A nurse is using clinical experience and client preference to guide clinical decision making.Which of the following is being demonstrated by the nurse?&#10;A) Evidence-based practice&#10;B) Internal evidence&#10;C) Research utilization&#10;D) External evidence

Accepted Answer

Internal evidence refers to the use of the nurse's clinical experiences and the client's preferences.Evidence-based practice includes the best available evidence from a variety of sources,including research studies,nursing experience and expertise,and community leaders.Research utilization is the process of transforming research knowledge into practice and the use of research to guide clinical practice.External evidence includes research and other evidence,like reports and professional guidelines.

Question 6

Evidence-based public health (EBPH)is:&#10;A) an integration of the best available nursing expertise.&#10;B) derived from community principles to fit the area where it is practiced.&#10;C) a health endeavor that makes informed use of evidence.&#10;D) comprised of only public health records.

Accepted Answer

EBPH is a public health endeavor in which there is an informed,explicit,and judicious use of evidence that has been derived from any of a variety of science and social science research and evaluation methods.EBPH includes more than public health records.EBPH is not an integration of nursing expertise.EBPH is not derived from community principles.

Question 7

Which are barriers to implementation of evidence-based practice? (Select all that apply.)&#10;A) Lack of available time&#10;B) Inferior quality of available research&#10;C) Unwillingness of organizations to fund research&#10;D) Inability to understand the evidence&#10;E) Limited support from accreditors to implement evidence

Accepted Answer

Lack of time,inferior quality of research,unwillingness of organizations to fund research,and inability to understand the evidence are all barriers to the implementation of evidence-based practice.As public health departments are beginning to seek accreditation there is an increased emphasis on the use of evidence-based practice.

Question 8

A nurse is grading the strength of evidence when critiquing a research study.Which of the following domains will the nurse need to consider?&#10;A) Randomness, sample size, and blinding&#10;B) Selection, variables, and description&#10;C) Nursing, medicine, and physiology&#10;D) Quality, quantity, and consistency

Accepted Answer

Quality,quantity,and consistency are the three domains for evaluating systems.The others are not criteria used to grade the strength of evidence.

Question 9

A PHN uses a published systematic review to determine which exercises should be incorporated into a newly developed older adult exercise program.Which of the following resources would most likely contain this information?

A) Evidence-Based Practice for Public Health Project
B) PubMed
C) Cochrane Public Health Group (PHRG)
D) Task Force on Community Preventive Services

Accepted Answer

The PHRG works with contributors to produce and publish Cochrane reviews of the effects of population-level public health interventions.The PHRG undertakes systematic reviews of the effects of public health interventions to improve health and other outcomes at the population level,not those targeted at individuals.The Evidence-Based Practice for Public Health Project provides access to numerous databases of interest concerning public health.PubMed is a bibliographical database that includes references for nursing,medicine,dentistry,the health care system,and preclinical sciences.The Task Force on Community Preventive Services is charged with determining the topics to be addressed by the CDC's Community Guide and the most appropriate means to assess evidence regarding population-based interventions.

Question 10

A nurse researcher is planning to use blinding when designing a research study.In which of the following instances would this be most important?&#10;A) Using a small sample size&#10;B) Measuring outcomes accurately&#10;C) Using a control group&#10;D) Studying the attrition rate

Accepted Answer

Blinding refers to a procedure where the researcher or evaluator does not know which participants are in the experimental or control group.The other factors do not relate to the importance of blinding.

Question 11

A nurse makes clinical judgments based upon trial and error and past clinical experiences.Which of the following problems can result from using these data sources in clinical decision making?&#10;A) Not all sources of information are reliable.&#10;B) Authority always leads to faulty decision making.&#10;C) Ethical knowledge is not taken into account.&#10;D) Trial and error has led to poor outcomes.
