Question 1
A nurse practitioner notices that patients with heart failure who receive structured
telehealth follow-up appear to have fewer hospital readmissions than those
receiving standard discharge instructions. She wants to investigate this observation
using evidence-based practice.
Which PICOT question is most appropriate?
A. Does telehealth improve nursing communication?
B. In adults with heart failure, does structured telehealth follow-up compared with
standard discharge education reduce 30-day hospital readmissions?
C. Should hospitals implement telehealth for all patients?
D. Are heart failure patients satisfied with telehealth services?
Answer: B
Rationale: A strong PICOT question clearly identifies the Population,
Intervention, Comparison, Outcome, and Time. Option B includes all required
elements and is measurable.
,Question 2
A researcher is searching for the highest level of evidence regarding the
effectiveness of mindfulness interventions for chronic pain.
Which source should be reviewed first?
A. Expert opinion article
B. Qualitative phenomenological study
C. Systematic review with meta-analysis
D. Case-control study
Answer: C
Rationale: Systematic reviews and meta-analyses synthesize multiple high-quality
studies and represent the highest level of evidence for intervention questions.
Question 3
Investigators randomly assign diabetic patients to receive either a new glucose-
monitoring application or standard monitoring. Six months later, average HbA1c
levels are compared.
Which variable is the dependent variable?
A. Type of glucose-monitoring method
B. Randomization process
C. HbA1c level after six months
D. Patient age
Answer: C
Rationale: The dependent variable is the measured outcome affected by the
intervention. HbA1c is the outcome being evaluated.
,Question 4
A qualitative investigator conducts lengthy interviews with women recently
diagnosed with breast cancer to better understand how they experienced receiving
the diagnosis.
Which qualitative design is being used?
A. Ethnography
B. Grounded theory
C. Phenomenology
D. Narrative review
Answer: C
Rationale: Phenomenology explores the lived experiences of individuals
surrounding a specific phenomenon.
Question 5
Researchers compare three different exercise programs to determine which
produces the greatest reduction in blood pressure.
Which statistical test is most appropriate?
A. Chi-square
B. Independent t-test
C. ANOVA
D. Pearson correlation
Answer: C
Rationale: ANOVA compares the means of three or more independent groups.
, Question 6
An investigator reports an ANOVA result with p = 0.02.
What should occur next?
A. Accept the null hypothesis.
B. Perform a post-hoc analysis.
C. Repeat the entire study.
D. Conclude all groups are identical.
Answer: B
Rationale: When ANOVA demonstrates statistical significance (p < .05), post-hoc
testing identifies which groups differ.
Question 7
A hospital educator distributes surveys only to nurses attending an optional
professional development seminar.
Which sampling method is being used?
A. Stratified random sampling
B. Convenience sampling
C. Cluster sampling
D. Systematic random sampling
Answer: B
Rationale: Convenience sampling selects participants based on availability rather
than random selection.
