,NSG 324 Exam 1 Research and Evidence-Based Practice Questions
And Answers 2026/2027 Grand canyon university
Q1. Which combination best represents the core components of
evidence-based practice in nursing?
A) Nursing tradition, physician preference, and hospital policy
B) Research evidence, nursing diagnosis, and patient compliance
C) Best available evidence, clinical expertise, and patient preferences and
values
D) Clinical experience, organizational policy, and textbook recommendations
Correct Answer: C) Best available evidence, clinical expertise, and patient
preferences and values
Rationale: Evidence-based practice integrates the strongest available
evidence with the nurse's clinical expertise and the patient's preferences,
values, and circumstances.
Q2. What is a primary function of nursing theory in research and
practice?
A) To replace clinical judgment
B) To organize concepts and provide a framework for understanding nursing
phenomena
C) To establish hospital billing procedures
D) To eliminate the need for research evidence
Correct Answer: B) To organize concepts and provide a framework for
understanding nursing phenomena
Rationale: Nursing theories organize concepts and relationships that help
explain phenomena, guide practice, and provide direction for research.
Q3. Which statement best distinguishes evidence-based practice
from nursing research?
A) Evidence-based practice produces research data, whereas research
applies existing evidence.
B) Nursing research depends only on qualitative methods, whereas EBP
depends only on quantitative methods.
C) Nursing research and EBP are identical processes with different names.
D) Evidence-based practice integrates research findings with clinical
expertise and patient preferences to guide care.
,Correct Answer: D) Evidence-based practice integrates research findings with
clinical expertise and patient preferences to guide care.
Rationale: Research generates or tests knowledge, whereas EBP uses
available evidence together with clinical expertise and patient preferences to
make care decisions.
Q4. What is a quality indicator in health care?
A) A measurable variable used to assess an aspect of health care
performance or outcomes
B) A nursing theory used to explain patient behavior
C) A database used to locate journal articles
D) A statistical test used to determine research significance
Correct Answer: A) A measurable variable used to assess an aspect of health
care performance or outcomes
Rationale: Quality indicators provide measurable information about
processes or outcomes of care and can reveal areas requiring improvement.
Q5. Which database is especially useful when searching for nursing
and allied health literature?
A) A hospital billing database
B) CINAHL
C) A medication administration record
D) A general financial database
Correct Answer: B) CINAHL
Rationale: CINAHL is specifically oriented toward nursing and allied health
literature and is commonly used to locate nursing research.
Q6. Which resource is primarily designed to provide access to
biomedical and life-science literature?
A) A hospital incident-reporting system
B) A nursing staffing database
C) PubMed
D) An electronic medication administration record
Correct Answer: C) PubMed
, Rationale: PubMed provides access to a large body of biomedical and life-
science literature, making it an important research resource for health
professionals.
Q7. A nurse selects a peer-reviewed journal article that directly
addresses the clinical problem under investigation. Which
characteristic makes the source especially useful?
A) It contains scholarly research relevant to the clinical question.
B) It is prominently displayed on a commercial website.
C) It has the largest number of references regardless of relevance.
D) It is the newest document available, regardless of study quality.
Correct Answer: A) It contains scholarly research relevant to the clinical
question.
Rationale: A useful research source should be scholarly, relevant to the
question, and sufficiently rigorous to support clinical decision-making.
Q8. A nurse combines current research evidence, clinical
experience, and an adult patient's preference when selecting
between two evidence-supported interventions. What is this nurse
demonstrating?
A) Research replication
B) Quality assurance only
C) Experimental research
D) Evidence-based practice
Correct Answer: D) Evidence-based practice
Rationale: The decision combines evidence with professional expertise and
the individual patient's preferences, which is the foundation of EBP.
Q9. Which statement best distinguishes quality improvement from
research?
A) Quality improvement never uses data.
B) Research is always performed without patients.
C) Quality improvement cannot involve evidence-based practice.
D) Quality improvement commonly evaluates and improves processes within
a specific setting, whereas research seeks to generate or test knowledge.
