ANSWERS WITH RATIONALES HIGH-YIELD
TESTEST AND APPROVED GURANTEEND
PASS A+
SECTION 1: FOUNDATIONS OF NURSING RESEARCH (Qs 1-25)
Q1. A nurse researcher wants to understand the lived experience
of cancer survivors. Which research approach is most appropriate?
a) Randomized controlled trial
b) Phenomenology
c) Correlational study
d) Quasi-experimental design
Answer: b) Phenomenology
Rationale: Phenomenology explores lived experiences to
understand the essence of a phenomenon. RCTs test
interventions, correlational studies examine relationships, and
quasi-experimental designs test cause-effect without
randomization.
Q2. Which statement about the independent variable (IV) is
correct?
a) It is the outcome measured in a study.
, Page 2 of 59
b) It is manipulated or selected by the researcher to cause an
effect.
c) It cannot be changed in experimental research.
d) It is only used in qualitative studies.
Answer: b) It is manipulated or selected by the researcher to
cause an effect.
Rationale: The IV is the presumed cause or intervention. The
dependent variable (DV) is the outcome. IVs are central to
experimental/quasi-experimental designs, not qualitative.
Q3. A study examines the relationship between hours of sleep and
pain levels in post-op patients. What type of research is this?
a) Experimental
b) Descriptive
c) Correlational
d) Historical
Answer: c) Correlational
Rationale: Correlational research examines relationships between
two or more variables without manipulation. No intervention is
applied.
Q4. Which level of evidence (LOE) is considered the strongest for
therapy questions?
a) Systematic review of RCTs
b) Single RCT
c) Case-control study
d) Expert opinion
Answer: a) Systematic review of RCTs
Rationale: According to evidence hierarchies (e.g., Joanna Briggs,
, Page 3 of 59
GRADE), systematic reviews and meta-analyses of RCTs provide
the highest level of evidence for intervention effectiveness.
Q5. The nurse critically appraises a study to determine if the
findings are applicable to her unit. This represents:
a) Validity
b) Reliability
c) Generalizability
d) Transferability
Answer: d) Transferability (qualitative context) or Generalizability
(quantitative context). Best answer: Generalizability.
Rationale: Generalizability refers to the extent study findings can
be applied to other populations/settings. Transferability is
analogous in qualitative research.
Q6. In qualitative research, the term for the accuracy and
trustworthiness of findings is:
a) Validity
b) Reliability
c) Trustworthiness
d) Objectivity
Answer: c) Trustworthiness
Rationale: Trustworthiness encompasses credibility,
dependability, confirmability, and transferability – the qualitative
parallel to validity/reliability.
Q7. A researcher wants to test a new wound care protocol using
random assignment to treatment or control groups. This is a:
a) Quasi-experimental design
b) Correlational design
, Page 4 of 59
c) True experimental design
d) Descriptive design
Answer: c) True experimental design
Rationale: True experiments require randomization, control
group, and manipulation of IV. Quasi-experimental lacks
randomization.
Q8. Which sampling method ensures every member of the
population has an equal chance of being selected?
a) Convenience sampling
b) Purposive sampling
c) Simple random sampling
d) Snowball sampling
Answer: c) Simple random sampling
Rationale: Simple random sampling is probabilistic and unbiased.
Convenience, purposive, and snowball are non-probability
methods.
Q9. A nurse researcher uses the PICO format to develop a clinical
question. What does "C" stand for?
a) Control
b) Comparison
c) Clinical
d) Criteria
Answer: b) Comparison
Rationale: PICO = Population, Intervention, Comparison,
Outcome. Comparison is the alternate intervention or standard
care.
