Introduction
This WGU C790 Nursing Exam format for the 2026/2027 academic cycle reflects the standardized
assessment used in Western Governors University nursing programs to evaluate competency in
evidence-based practice and healthcare quality improvement. The exam measures knowledge of patient
safety initiatives, healthcare data interpretation, interprofessional collaboration, and evidence-based
strategies used to improve patient outcomes and healthcare system performance. This comprehensive
examination assesses nursing students' readiness to apply theoretical knowledge to clinical scenarios
and make evidence-based decisions in complex healthcare environments.
Exam Structure
The WGU C790 Nursing Exam is structured as follows:
• 70 multiple-choice questions
• Single-best-answer format
• Scenario-based clinical judgment and evidence-based practice decision-making items
Answer Format
All correct answers are presented in bold and green, followed by clearly defined rationales
explaining clinical priorities, quality improvement considerations, and evidence-based nursing
decision-making. Each rationale provides the evidence-based reasoning that supports the correct
answer, helping students understand the underlying principles and apply them to similar clinical
scenarios.
Examination Questions
1. A nurse is implementing evidence-based practice (EBP) in a clinical setting. Which component is
considered the foundation of the EBP process?
A) Clinical expertise alone
B) Patient preferences and values
C) Best available research evidence
D) Traditional nursing practices
Correct Answer: C - Best available research evidence
Rationale: Evidence-based practice integrates three components: best available research
evidence, clinical expertise, and patient preferences. Research evidence serves as the
foundation because it provides objective, systematically gathered data that informs clinical
decision-making. While clinical expertise and patient values are essential, they must be
grounded in current research findings to ensure optimal outcomes.
2. When appraising the quality of a systematic review for evidence-based practice, which factor is
most critical?
A) Number of studies included
B) Publication date of the review

, WGU C790 Nursing Examination 2026/2027
C) Methodological rigor and transparency
D) Reputation of the journal
Correct Answer: C - Methodological rigor and transparency
Rationale: Methodological rigor and transparency are paramount when appraising
systematic reviews. This includes clear inclusion/exclusion criteria, comprehensive search
strategies, quality assessment of primary studies, and appropriate synthesis methods. A well-
conducted systematic review with fewer studies is more valuable than a poorly conducted one
with many studies.
3. A nurse researcher is using the PICO framework to formulate a clinical question. What does the 'C'
in PICO represent?
A) Clinical setting
B) Comparison intervention
C) Cost-effectiveness
D) Critical appraisal
Correct Answer: B - Comparison intervention
Rationale: In the PICO framework, P = Population/Patient/Problem, I = Intervention, C =
Comparison intervention, and O = Outcome. The comparison intervention allows clinicians to
evaluate the effectiveness of an intervention against alternatives, including standard care,
placebo, or no treatment.
4. Which hierarchy of evidence places systematic reviews of randomized controlled trials at the
highest level?
A) Cochrane hierarchy
B) GRADE system
C) Levels of evidence from research synthesis
D) All established evidence hierarchies
Correct Answer: D - All established evidence hierarchies
Rationale: Systematic reviews of randomized controlled trials (RCTs) consistently occupy
the highest position in evidence hierarchies, including the Cochrane hierarchy, GRADE
system, and various research synthesis frameworks. This placement reflects the
methodological strength of synthesizing multiple high-quality RCTs to provide the most
reliable evidence.
5. A nurse encounters conflicting research evidence regarding a clinical intervention. What is the most
appropriate action?
A) Follow the most recent study
B) Apply the intervention with the largest sample size
C) Seek high-quality systematic reviews and meta-analyses
D) Rely on unit protocols without further investigation
Correct Answer: C - Seek high-quality systematic reviews and meta-analyses
Rationale: When facing conflicting evidence, systematic reviews and meta-analyses provide
the most comprehensive synthesis of available research. These resources critically appraise
and combine findings from multiple studies, offering a higher level of evidence than
individual studies and helping clinicians navigate discrepancies.
6. Which strategy best promotes the translation of research evidence into clinical practice?
A) Publishing findings in academic journals
B) Conducting single-site research studies
C) Implementing evidence-based clinical practice guidelines
