The nurse is caring for a patient with chronic low back pain. In providing care for this patient, the nurse wonders whether the guidelines utilized for this type of pain are adequate. The nurse wants to determine the best evidence-based practice regarding these guidelines. What is the best database for the nurse to access?

AHRQ 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.

In caring for patients, it is important for the nurse to realize that evidence-based practice is:

Dependent on patient values and expectations.

The variable that is synonymous with the outcome of interest is called the:

Dependent variable

The measurement of the magnitude of the impact of an intervention is referred to as the:

Effect size

The FINER model gives guidance in the appraisal of a research question. The E in the acronym stands for:

Ethical

Which of the following research designs is used to answer questions that seek to investigate causality?

Experimental design

The ability for a nurse to generalize findings fro a study to other people, places, and situations is called

External validity

A Factors that exert an effect on the outcome but that are not part of the planned experiment and may confuse the interpretation of the results are referred to as:

Extraneous variables

Factors that exert an effect on the outcome but that are not part of the planned experiment and may confuse the interpretation of the results are referred to as:

Extraneous variables

Experimental studies are most often conducted in which type of setting?

Highly controlled setting laboratory or research unit

Experimental studies measure cause and effect. The variable that is synonymous with the "cause" is referred to as the:

Independent variable

The nurse is writing a research article on a patient care topic. The nurse realizes that the section that will get the reader to read the article because of the value of the topic for the reader is the:

Introduction

The type of hypothesis that declares there is no difference between groups is called a(an):

Null hypothesis

A nurse who works in a newborn nursery asks, "I wonder if the moms who breastfeed their babies would be able to breastfeed more successfully if we played peaceful music while they were breastfeeding." In this example of a PICOT question, the I is:

Peaceful Music

Because the Quality control committee is multidisciplinary in nature, and few members are nurses, it is imperative that the committee first:

Plan

Careful consideration of the ___________________________ serves as the basis for the research design.

Purpose to be achieved by the study

The research design that involves identifying the variables that represent characteristics of interest and then measuring them in a reliable and valid way is.

Quantitative research

Name the quantitative study? Determining the effectiveness of calcium with vitamin D3 on the bone density of patients

Quasi experimental study

A research study design that examines causality where the treatment is introduced to a group but random assignment and/or a control group is missing is called a

Quasi-experimental design

A scientific process for developing empirical knowledge for use in practice.

Research Rational: knowledge provides the strongest evidence for making changes in practice.

The potential participants who meet the definition of the population and are accessible to the researcher is referred to as the:

Sampling frame

A group of nurses have implemented an evidence-based practice (EBP) change and have evaluated the effectiveness of the change. Their next step is to:

Share the findings with others

In reviewing literature for an evidence-based practice study, the nurse realizes that the most reliable level of evidence is the:

Systematic review and meta-analysis.

Which of the following is most important to the researcher in selecting a research design?

The nature of the research problem

In collecting the best evidence, the gold standard for research is:

The randomized controlled trial (RCT).

EBP guidelines used in nursing practice typically include which type of knowledge?

Theoretical knowledge

When evaluating quality improvement (QI) programs in relation to evidence-based practice (EBP), it is easy to note that:

When implementing EBP projects, it is important to review QI data.
