70-413 Exam Research & Evidence-Based Practice 4

Question 1

A nurse wants to implement a new wound care protocol based on recent evidence. According to the EBP process, what is the FIRST step?

Accepted Answer

Ask a clinical question in PICO format

Answer

The first step in evidence-based practice is formulating a focused clinical question using the PICO framework to guide the literature search.

Question 2

Which of the following is an example of a primary research source?

Accepted Answer

An original study reporting new data collected by the researchers

Answer

A primary source is an original research report where the authors directly collected and analyzed data, as opposed to secondary sources that synthesize others' work.

Question 3

When evaluating an article's level of evidence, a nurse finds it is a well-designed case-control study. Where does this fall on the evidence hierarchy?

Accepted Answer

Level V — low

Answer

Case-control studies typically fall at Level III or IV (moderate evidence) on most hierarchies, below RCTs and systematic reviews but above expert opinion and descriptive studies.

Question 4

A clinical practice guideline differs from a systematic review primarily because it:

Accepted Answer

Provides specific recommendations for clinical practice based on synthesized evidence

Answer

A clinical practice guideline translates synthesized evidence into actionable, specific recommendations intended to guide clinical decisions, whereas a systematic review summarizes and appraises existing research without prescribing practice.

Question 5

Which step in the EBP process involves determining whether research evidence is applicable to a specific patient population?

Accepted Answer

Integrating evidence with clinical expertise and patient values

Answer

Integration is the step where clinicians combine the best available evidence with their expertise and the patient's unique circumstances, values, and preferences to inform clinical decisions.
