Questions and Correct Answers
Purposes of research ✅Intervention/therapy
Diagnosis/assessment
Prognosis
Etiology (causation)
Description
Meaning/process
Intervention/therapy ✅learn about the effects of specific actions, products, or
processes (what interventions most effectively lead to an outcome?)
Diagnosis/assessment ✅develop and evaluate instruments to screen, diagnose, and

Level III: Nonrandomized trial (quasi-experiment)
Level IV: Systematic review of nonexperimental (observational) studies
Level V: Non Experimental/observational study
Level VI: Systematic review/metasynthesis of qualitative studies
Level VII: Qualitative study/descriptive study
Level VIII: nonresearch source (internal evidence, expert opinion)
Evidence hierarchy levels: Level 1 ✅systematic review/meta-analysis of RCTs
Evidence hierarchy levels: Level II ✅Randomized controlled trials (RCT)
Evidence hierarchy levels: Level III ✅Nonrandomized trial (quasi-experiment)
, Evidence hierarchy levels: Level IV ✅Systematic review of nonexperimental
(observational) studies

Three components of EBP ✅Best evidence
Clinical expertise
Patient preferences/values
Barriers to EBP ✅-Quality and nature of the research (scarcity of strong research
evidence)
-Characteristics of nurses (inadequate skills in locating and appraising evidence)
-Organizational factors (lack of financial support and staff release time for EBP)
Research to Practice Gap
EBP process (part 2) ✅Step 0: cultivate a spirit of inquiry
Step 1: ask a PICOT question
Step 2: Search for evidence
Step 3: appraise evidence
Step 4: integrate evidence with clinical expertise and patient preferences and values
into decision making
Step 5: evaluate outcomes
Step 6: Disseminate results
Components of a PICOT question ✅P: Patient/population/problem
I: Intervention (variable)
C: comparison (if applicable)
O: Outcome
T: Timeframe (optional)
Qualitative Research ✅more subjective
