A nurse is conducting a staff education about evidence-based practice. Number the following steps of evidence-based reports in the appropriate order.
Explanation
Evidence-Based Practice (EBP) is a structured process that integrates the best available research evidence with clinical expertise and patient preferences to improve outcomes. To effectively implement EBP, nurses must follow a systematic approach that begins with asking the right question and ends with making evidence-informed recommendations.
Rationale for correct answer:
Step 1: Ask the clinical question
The EBP process begins with formulating a focused, answerable question-often using the PICO format. This step guides the literature search and ensures that the review is relevant to the clinical issue at hand.
Step 2: Analysis of scientific data
Once relevant research is gathered, it must be analyzed critically to determine what the studies found. This includes evaluating results, statistical significance, and how the findings apply to the clinical setting.
Step 3: Level of evidence
After analyzing the data, the quality and strength of the evidence are determined. This step involves grading the studies based on the hierarchy of evidence, with systematic reviews and randomized controlled trials ranked highest.
Step 4: Recommendations for practice
Based on the strength and applicability of the evidence, the final step is to formulate recommendations that can be implemented in clinical practice to improve outcomes.
Take home points:
- Following a structured sequence in EBP ensures clinical decisions are grounded in solid evidence.
- The first and most important step in EBP is asking a clear clinical question.
A nurse is attending a staff training on evidence-based practice. Match the components of PICO using the question “Does the use of guided imagery compared with standard care affect the postoperative pain in hospitalized adolescents?
Explanation
The PICO format is a framework used in evidence-based practice (EBP) to help clinicians formulate well-structured, answerable clinical questions and guide effective literature searches. PICO stands for Population/Problem, Intervention, Comparison, and Outcome.
Correct answers:
P) Patient/Population → 3. Hospitalized adolescents
This identifies the population being studied-the group affected by the clinical problem.
(I) Intervention → 4. Guided imagery
This is the new or experimental treatment being evaluated.
(C) Comparison → 1. Adolescents receiving standard care
This represents the control or usual care group against which the intervention is compared.
(O) Outcome → 2. Postoperative pain
This is the measurable effect or result being examined to determine the intervention's impact.
Take home points:
- The PICO format helps structure clinical questions clearly and concisely, guiding effective literature searches and research evaluation.
- Accurately identifying each component improves the nurse's ability to integrate evidence into clinical decision-making.
A nurse is educating student nurses about the PICO format. In the PICO format for phrasing research questions and identifying key terms for a literature search, what does the “P” stand for?
Nurses in a community clinic are conducting an evidenced based practice (EBP) project focused on improving the outcomes of children with asthma. The PICO question asked by the nurses is “In school-age children, does the use of an electronic gaming education module versus educational books affect the usage of inhalers?” In the question, what is the “O”?
A nurse research investigator is explaining a research study to a client. The client is interested in participating in the research study. The nurse investigator reviews the informed consent with the client. The client asks the nurse why he must sign the consent to participate in the study. What is the nurse’s best response(s) to the client’s question? Select all that apply
When a nurse asks a student nurse why it is necessary to change the client’s bed every day, he says, “I guess we have always done it that way.” This answer is an example of which of the following?
