EVIDENCE-BASED PRACTICE NURSING EXAM 2026 200 PRACTICE QUESTIONS &
DETAILED EXPERT RATIONALE NCLEX-READY STUDY GUIDE
QUESTION 1
Which of the following best defines Evidence-Based Practice (EBP) in nursing?
A. Following hospital policies and procedures without question
B. Using only personal clinical experience to make patient care decisions
C. Integrating best research evidence with clinical expertise and patient preferences
D. Applying the most recent nursing textbook information to all patients
E. Implementing care based solely on physician orders
CORRECT ANSWER: C. Integrating best research evidence with clinical
expertise and patient preferences
EXPERT RATIONALE: EBP is defined as the conscientious, explicit, and judicious
use of current best evidence, combined with clinical expertise and patient values, to
guide healthcare decisions. This three-part model ensures care is individualized,
current, and scientifically supported.
,QUESTION 2
Which model is most commonly used to guide the implementation of
Evidence-Based Practice in nursing settings?
A. Maslow's Hierarchy of Needs
B. The Iowa Model of Evidence-Based Practice
C. Orem's Self-Care Deficit Theory
D. The Roy Adaptation Model
E. Nightingale's Environmental Theory
CORRECT ANSWER: B. The Iowa Model of Evidence-Based Practice
EXPERT RATIONALE: The Iowa Model is one of the most widely adopted
frameworks for EBP in clinical settings. It provides a structured, decision-making
algorithm that guides nurses from identifying a problem or knowledge trigger
through evaluating outcomes after implementing a practice change.
QUESTION 3
In the PICO(T) framework, what does the letter "P" represent?
A. Population or Patient problem
B. Primary outcome
C. Practice setting
D. Probability of success
E. Protocol used
CORRECT ANSWER: A. Population or Patient problem
EXPERT RATIONALE: PICO(T) stands for Population/Patient problem,
Intervention, Comparison, Outcome, and Time. The "P" helps the nurse clearly
define who the question is about, which focuses the literature search and makes
findings more applicable to the target group.
,QUESTION 4
Which level of evidence is considered the highest in the hierarchy of
evidence?
A. Expert opinion
B. Case study
C. Randomized Controlled Trial (RCT)
D. Systematic review and meta-analysis
E. Cohort study
CORRECT ANSWER: D. Systematic review and meta-analysis
EXPERT RATIONALE: Systematic reviews and meta-analyses sit at the top of the
evidence hierarchy because they synthesize findings from multiple high-quality
studies, reducing bias and increasing the reliability and generalizability of
conclusions used to guide clinical practice.
QUESTION 5
A nurse wants to find the best evidence on preventing pressure ulcers. Which
database is most appropriate to search?
A. Wikipedia
B. Google Scholar only
C. PubMed/MEDLINE
D. Social media nursing groups
E. Hospital intranet only
CORRECT ANSWER: C. PubMed/MEDLINE
EXPERT RATIONALE: PubMed/MEDLINE is the premier biomedical database
maintained by the National Library of Medicine. It indexes peer-reviewed literature
, and is the most appropriate starting point for clinical evidence searches in nursing
and medicine.
QUESTION 6
Which of the following research designs provides the strongest evidence for
causality?
A. Qualitative research
B. Descriptive study
C. Cross-sectional study
D. Randomized Controlled Trial (RCT)
E. Case report
CORRECT ANSWER: D. Randomized Controlled Trial (RCT)
EXPERT RATIONALE: RCTs use random assignment to experimental and control
groups, minimizing selection bias and confounding variables. This design is the gold
standard for establishing cause-and-effect relationships between interventions and
outcomes.
QUESTION 7
A nurse reads a study with a p-value of 0.03. What does this indicate?
A. The study has a 3% chance of being replicated
B. There is a 3% probability that the results occurred by chance
C. The intervention works 97% of the time
D. The sample size was too small
E. The findings are clinically significant
CORRECT ANSWER: B. There is a 3% probability that the results occurred by
chance
