NURSING
1. Which best defines evidence-based practice (EBP)?
A. Using only expert opinion in clinical decisions
B. Combining best research evidence, clinical expertise, and patient preferences
C. Following hospital policies exclusively
D. Using traditional nursing methods only
Answer: B
Rationale: EBP integrates research evidence, clinical judgment, and patient values for optimal
care decisions.
2. What is the primary purpose of nursing research?
A. Increase hospital revenue
B. Generate new knowledge to improve nursing practice
C. Replace clinical judgment
D. Reduce documentation time
Answer: B
Rationale: Nursing research systematically generates knowledge to improve patient outcomes
and practice.
3. Which is an example of a quantitative research design?
,A. Phenomenology
B. Grounded theory
C. Randomized controlled trial
D. Ethnography
Answer: C
Rationale: RCTs involve numerical data and controlled experimental methods.
4. What is a characteristic of qualitative research?
A. Uses statistical analysis only
B. Focuses on lived experiences and meaning
C. Requires large sample sizes
D. Always uses randomized groups
Answer: B
Rationale: Qualitative research explores meaning, perception, and experience.
5. What is the first step in the research process?
A. Data analysis
B. Identifying the research problem
C. Literature review
D. Hypothesis testing
Answer: B
Rationale: Research begins with identifying and defining a problem.
6. What is a hypothesis?
A. A data collection tool
B. A predicted relationship between variables
C. A research design
D. A sampling method
Answer: B
Rationale: A hypothesis is a testable prediction about relationships between variables.
7. What is the purpose of a literature review?
,A. Collect raw patient data
B. Summarize existing knowledge on a topic
C. Replace data analysis
D. Avoid research duplication only
Answer: B
Rationale: It provides background, gaps, and justification for research.
8. What is a dependent variable?
A. The variable manipulated by the researcher
B. The outcome being measured
C. A sampling technique
D. A type of research design
Answer: B
Rationale: The dependent variable is the outcome affected by the independent variable.
9. Which sampling method gives every member of a population an equal chance of
selection?
A. Convenience sampling
B. Purposive sampling
C. Random sampling
D. Snowball sampling
Answer: C
Rationale: Random sampling reduces bias by giving equal selection probability.
10. What is the primary purpose of peer review in research?
A. Increase publication speed
B. Ensure quality, validity, and credibility of research
C. Reduce study costs
D. Replace data collection
Answer: B
Rationale: Peer review evaluates research quality before publication.
11. What is the main purpose of a theoretical framework in research?
, A. To replace data collection
B. To guide the study design and interpretation of results
C. To increase sample size
D. To eliminate bias completely
Answer: B
Rationale: A theoretical framework provides structure for designing the study and interpreting
findings.
12. What is a key characteristic of a good research problem?
A. Broad and unfocused
B. Clear, focused, and researchable
C. Based only on opinion
D. Impossible to measure
Answer: B
Rationale: A strong research problem is specific and can be studied systematically.
13. What is the purpose of operational definitions in research?
A. Define variables in measurable terms
B. Increase sample bias
C. Replace hypotheses
D. Eliminate literature review
Answer: A
Rationale: Operational definitions explain how variables are measured or identified.
14. Which best describes validity in research?
A. Consistency of measurement
B. Accuracy of what the instrument measures
C. Random selection of samples
D. Size of the population
Answer: B
Rationale: Validity refers to whether a tool measures what it is intended to measure.
15. What does reliability refer to?
