Questions and Answers Graded A+
1. Which of the following is the primary goal of Evidence-
Based Practice (EBP) in the clinical setting?
Correct Answer: C) Improving patient outcomes through
validated research
Rationale: The primary driver of EBP is to improve patient
outcomes by integrating the best research with clinical expertise
and patient preferences.
2. In the PICOT format for framing clinical questions, what
does the "I" represent?
Correct Answer: B) Intervention
Rationale: In the PICOT acronym, "I" stands for the intervention
or issue being studied.
3. What is a parameter in research?
Correct Answer: B) A numerical characteristic of a population
Rationale: A parameter is a characteristic of a population,
whereas a statistic is a characteristic of a sample.
, 4. Which of the following is NOT a scale of measurement in
research?
Correct Answer: D) Qualitative
Rationale: The four scales of measurement are nominal, ordinal,
interval, and ratio.
5. What is the difference between a one-tailed and a two-
tailed test?
Correct Answer: A) A one-tailed test assesses the effect in one
direction; a two-tailed test assesses both directions
Rationale: A one-tailed test looks for an effect in one direction,
while a two-tailed test looks for an effect in either direction.
6. A nurse researcher is looking for the "gold standard" of
evidence to support a change in wound care protocols. Which
source represents the highest level of evidence?
Correct Answer: A) Systematic reviews or meta-analyses of
RCTs
Rationale: Systematic reviews and meta-analyses of RCTs are
considered the highest level of evidence in the hierarchy.
7. A major benefit of electronic health records (EHRs) is:
Correct Answer: B) Improved access to patient information
Rationale: EHRs allow immediate access to health information
across providers, improving coordination and safety.
8. What is the definition of a quartile?
, Correct Answer: B) Special percentiles dividing sorted data
into four equal parts
Rationale: Quartiles divide data into four equal parts; Q1 is the
25th percentile, Q2 is the 50th (median), and Q3 is the 75th.
9. What does a p-value represent in hypothesis testing?
Correct Answer: The likelihood that the results occurred by
chance
Rationale: A p-value indicates the probability that the observed
results are due to chance. A p-value < 0.05 is often considered
statistically significant.
10. Which research design is best suited for studying cause-
and-effect relationships?
Correct Answer: C) Experimental research
Rationale: Experimental research involves manipulation of
variables and control of extraneous factors, making it ideal for
determining causality.
11. Which action best demonstrates clinical judgment?
Correct Answer: B) Identifying subtle changes in patient
status
Rationale: Clinical judgment involves recognizing meaningful
changes, interpreting data, and anticipating complications.
12. Which data point is most concerning for a patient with
chronic kidney disease?
Correct Answer: C) Potassium 5.8 mEq/L
, Rationale: Hyperkalemia (potassium > 5.0 mEq/L) poses an
immediate risk for lethal cardiac dysrhythmias.
13. A nurse notices a medication dose is unclear. What is the
best action?
Correct Answer: C) Clarify the order with the provider
Rationale: Unclear medication orders threaten patient safety and
must be clarified before administration.
14. Which ethical principle supports honoring a competent
patient's decision to refuse care?
Correct Answer: D) Autonomy
Rationale: Autonomy respects a patient's right to make their own
healthcare decisions.
15. A competent adult patient refuses a blood transfusion
based on personal beliefs. Which action best reflects the
ethical principle of autonomy?
Correct Answer: C) Respect the patient's refusal after ensuring
informed consent
Rationale: Respecting a competent patient's refusal after
ensuring they are fully informed upholds the principle of
autonomy.
16. A nurse advocates for pain management for a
postoperative patient. Which ethical principle is primarily
demonstrated?
Correct Answer: B) Beneficence
