NURSING RESEARCH AND EVIDENCE-
BASED PRACTICE QUESTIONS AND
DETAILED SOLUTIONS JUST
RELEASED
1. Which element of a PICO question describes the specific measurement used to evaluate
the effectiveness of an intervention?
A. Outcome
B. Intervention
C. Comparison
D. Population
Answer: A
Conceptual Explanation: The ‘O’ in PICO stands for Outcome, which represents the
specific result or measurement the researcher is looking for to determine the success of an
intervention.
2. In a Level I systematic review, what is the primary purpose of a forest plot?
A. To display the distribution of qualitative themes across studies
B. To identify outliers in a single cohort study
,C. To graphically represent the point estimates and confidence intervals of multiple studies
D. To map the geographic location of research participants
Answer: C
Conceptual Explanation: A forest plot is used in meta-analyses to show the effect sizes
and confidence intervals for each study included, allowing for a visual assessment of the
overall evidence.
3. Which threat to internal validity occurs when an external event happens during the study
that affects the participants’ responses?
A. Maturation
B. Selection bias
C. History
D. Attrition
Answer: C
Conceptual Explanation: History refers to events occurring concurrently with the study
that can influence the dependent variable, independent of the intervention.
4. What is the defining characteristic of a True Experimental design compared to a Quasi-
experimental design?
A. The use of a pre-test
B. The inclusion of a control group
, C. Random assignment to groups
D. Longitudinal data collection
Answer: C
Conceptual Explanation: Random assignment is the hallmark of true experimental
designs, whereas quasi-experimental designs lack random assignment despite having a
control group or multiple measurements.
5. A researcher is studying the lived experience of parents whose children have terminal
cancer. Which qualitative tradition is most appropriate?
A. Grounded Theory
B. Ethnography
C. Phenomenology
D. Historical Research
Answer: C
Conceptual Explanation: Phenomenology focuses on describing the ‘lived experience’ of
individuals regarding a specific phenomenon.
6. Which type of sampling is most likely to result in a representative sample and reduce
selection bias?
A. Convenience sampling
B. Purposive sampling
