Nursing Research Exam Latest
Update 2026 With Questions And
Answers Plus Rationales Already
Graded A+
**1. What is the primary purpose of nursing research?**
A) To make nurses better at reading journal articles.
B) To generate evidence to guide nursing practice and improve patient outcomes.
C) To satisfy academic requirements for degree programs.
D) To prove that nursing is a science, not an art.
**Answer: B**
**Rationale:** The ultimate goal of nursing research is to build a body of scientific knowledge
that directly informs and improves clinical practice, patient care, and health outcomes. Options
A, C, and D are secondary or incorrect purposes.
**2. Which of the following is the first step in the evidence-based practice (EBP) process?**
A) Appraising the evidence.
B) Asking a well-built clinical question.
C) Implementing a change in practice.
D) Evaluating the outcome of the change.
**Answer: B**
,**Rationale:** The EBP process begins with asking a clinical question that arises from a
patient's problem. This question guides the search for evidence. The common mnemonic is
PICO(T).
**3. The "P" in the PICO(T) format for a clinical question stands for:**
A) Problem
B) Phenomenon
C) Patient/Population
D) Procedure
**Answer: C**
**Rationale:** PICO(T) stands for Patient/Population, Intervention, Comparison, Outcome, and
(sometimes) Time. The "P" defines the specific patient population of interest.
**4. Which type of research is considered the "gold standard" for evidence-based practice to
determine causality?**
A) Qualitative study
B) Randomized Controlled Trial (RCT)
C) Case study
D) Descriptive study
**Answer: B**
**Rationale:** An RCT is a quantitative study where participants are randomly assigned to
either a treatment or a control group. This design is the most robust for determining cause-and-
effect relationships because randomization minimizes bias.
**5. A nurse researcher wants to study the lived experiences of patients living with chronic
pain. Which research approach is most appropriate?**
A) Quantitative
,B) Quasi-experimental
C) Qualitative
D) Correlational
**Answer: C**
**Rationale:** Qualitative research is ideal for exploring subjective experiences, meanings, and
perspectives. The goal is to understand the "lived experience" of a phenomenon, not to
measure it numerically.
**6. Which of the following is a characteristic of quantitative research?**
A) Emphasizes individual experiences and meaning.
B) Uses inductive reasoning to generate hypotheses.
C) Relies on statistical analysis and numerical data.
D) Data is collected through open-ended interviews.
**Answer: C**
**Rationale:** Quantitative research is characterized by deductive reasoning, a focus on
objectivity, measurement, and the use of statistical tests to analyze numerical data.
**7. Evidence-based practice integrates the best research evidence with:**
A) The nurse's personal opinion.
B) Clinical expertise and patient preferences/values.
C) The hospital's financial resources.
D) The latest technology available.
**Answer: B**
**Rationale:** EBP is a three-legged stool: the best available research evidence, the clinician's
expertise, and the patient's unique values, preferences, and circumstances.
, **8. What is the primary difference between a research question and a hypothesis?**
A) A research question is always broader than a hypothesis.
B) A hypothesis is a predicted answer or expected outcome to a research question.
C) There is no difference; the terms are interchangeable.
D) A research question is only used in qualitative research.
**Answer: B**
**Rationale:** A research question is the overarching question a study seeks to answer. A
hypothesis is a formal, testable, and specific statement that predicts the relationship between
variables.
**9. A researcher tests the hypothesis: "Patients who receive a 10-minute back massage will
report lower pain scores than patients who do not." What is the independent variable?**
A) Pain scores
B) Patients
C) 10-minute back massage
D) The hospital unit
**Answer: C**
**Rationale:** The independent variable is the variable that is manipulated or controlled by
the researcher (the "intervention"). The outcome (pain scores) is the dependent variable.
**10. What does a "null hypothesis" state?**
A) There is a positive relationship between two variables.
B) There is a negative relationship between two variables.
C) There is no relationship or no difference between variables.
D) The results of the study will be significant.
