Course/Program: WGU D670 — Evidence-Based Practice and Applied
Nursing Research
Field of Study: Nursing Research, Evidence-Based Practice, Quality
Improvement, Clinical Inquiry
Level: Graduate, MSN, Nursing Education, Nursing Leadership
Edition: 2026–2027
Introduction
This comprehensive practice examination is designed for WGU graduate
nursing students preparing for D670 Task 1, which requires identifying a
clinical practice problem, developing a PICOT question, conducting a
literature search, and proposing an evidence-based practice change. It
contains 100 advanced multiple-choice questions covering evidence-
based practice foundations, PICOT development, literature search
strategies, research design and appraisal, levels of evidence,
implementation science, change theory, and evaluation methods. Each
question reflects current nursing research standards and real-world
clinical inquiry scenarios. The answer key provides detailed rationales to
reinforce critical thinking and scholarly writing skills. Use this document
to assess readiness, identify knowledge gaps, and strengthen
preparation for Task 1. All questions are original practice items and are
not from actual WGU assessments.

8. Ethical Considerations in Research
9. Evaluation and Sustainability of EBP
10. Scholarly Writing and Dissemination
1.
Which of the following best defines evidence-based practice (EBP)?
A) Relying solely on clinical experience to make patient care decisions
B) The integration of best research evidence, clinical expertise, and
patient values and preferences
C) Following institutional policies without question
D) Using only randomized controlled trials to guide practice
Correct Answer: B
Evidence-based practice is the conscientious, explicit, and judicious use
of current best evidence in combination with clinical expertise and
patient values to guide healthcare decisions. It is not solely experience,
policy, or one type of study. EBP integrates all three components.
2.
What is the first step in the evidence-based practice process?
A) Implementing the change
,B) Critically appraising the evidence
C) Formulating a clear, answerable clinical question
D) Evaluating outcomes
Correct Answer: C
The EBP process begins with formulating a focused clinical question,
often using the PICOT format. This guides the literature search and
subsequent steps. Implementation, appraisal, and evaluation occur
later.
3.
Which component of the PICOT format does the "I" represent?
A) Implementation
B) Intervention or exposure of interest
C) Investigation
D) Identification
Correct Answer: B
PICOT stands for Population/Patient, Intervention, Comparison,
Outcome, and Time. The "I" is the intervention or exposure being
considered. This is central to developing a searchable question.
4.
Which of the following is an example of a well-written PICOT question?
A) "Does hand hygiene reduce infection?"
B) "In hospitalized adults (P), does using an alcohol-based hand rub (I)
compared to soap and water (C) reduce hospital-acquired infection
rates (O) over a 6-month period (T)?"
C) "What is the best way to prevent falls?"
D) "Should nurses wash their hands?"
, Correct Answer: B
A well-formulated PICOT question includes all components: population,
intervention, comparison, outcome, and time. Options A, C, and D are
too broad and lack specificity, making them difficult to search and
answer.
5.
Which database is considered the most comprehensive for nursing and
allied health literature?
A) PubMed
B) CINAHL
C) Cochrane Library
D) ERIC
Correct Answer: B
CINAHL (Cumulative Index to Nursing and Allied Health Literature) is the
most comprehensive database for nursing and allied health literature.
PubMed is biomedical; Cochrane focuses on systematic reviews; ERIC is
education-focused.
6.
What is a Boolean operator used to narrow a literature search?
A) OR
B) AND
C) NOT
D) All of the above
Correct Answer: D
Boolean operators AND, OR, and NOT are used to combine or exclude
