Introduction:
This N262B Research Methods Midterm Review Exam format for 2026/2027 reflects the standardized
competency assessment used to evaluate proficiency in foundational nursing research and evidence-based practice
principles for nursing students. Note: "N262B" is an institution-specific course code (commonly associated with
UCLA School of Nursing); content below aligns with standard nursing research methods objectives taught in
such courses. The exam measures knowledge of EBP models, PICO/T formulation, literature search strategies,
, ethical principles (Belmont/IRB), research design differentiation, sampling methods, data collection
validity/reliability, critical appraisal fundamentals, basic statistical interpretation, and scenario-based application
of research concepts essential for safe, effective, evidence-based nursing practice. The comprehensive 75-question
format provides extensive coverage of these critical research domains, aligned with current AACN Essentials,
COPE guidelines, and institutional learning outcomes.
1. A nursing unit council is reviewing a recent increase in central line-associated bloodstream infections
(CLABSI). They decide to implement a new chlorhexidine bathing protocol based on a systematic review
of randomized controlled trials. This action best represents which of the following concepts?
1. Conducting primary nursing research
2. Quality improvement without evidence
3. Evidence-Based Practice (EBP)
4. Formulating a grounded theory
Correct Answer: C. Evidence-Based Practice (EBP)
Rationale: Evidence-Based Practice (EBP) is the integration of the best research evidence with clinical expertise and
patient values to facilitate clinical decision-making. Implementing a protocol based on a systematic review (high-level
evidence) to address a clinical issue is the hallmark of EBP. It is not primary research because they are applying existing
knowledge, not generating new knowledge.
2. According to the Iowa Model of Evidence-Based Practice, which of the following serves as a
"problem-focused trigger" for initiating an EBP project?
1. Publication of new national clinical guidelines
2. An increase in patient fall rates on a medical-surgical unit
3. A nurse reading a new research article on pain management
4. A mandate from a federal regulatory agency
Correct Answer: B. An increase in patient fall rates on a medical-surgical unit
Rationale: In the Iowa Model, triggers are categorized as either problem-focused or knowledge-focused.
Problem-focused triggers arise from clinical problems, risk management data, quality improvement data, or financial
data (e.g., an increase in fall rates). Knowledge-focused triggers arise from new research, new guidelines, or reading
literature.
3. A nurse researcher is formulating a clinical question: "In premature infants (P), how does kangaroo
care (I) compared to standard incubator care (C) affect weight gain (O) during the first month of life
(T)?" Which component of the PICOT framework represents the dependent variable?
1. Premature infants
2. Kangaroo care
3. Standard incubator care
4. Weight gain
Correct Answer: D. Weight gain
Rationale: The dependent variable is the outcome that the researcher is measuring to see if it changes as a result of the
intervention. In the PICOT format, the "O" (Outcome) represents the dependent variable. Here, weight gain is the
outcome being measured. The intervention (kangaroo care) is the independent variable.
4. Which of the following scenarios best illustrates the ethical principle of "Beneficence" as outlined in
the Belmont Report?
1. Ensuring that all participants sign an informed consent form before the study begins.
2. Selecting participants fairly without targeting vulnerable populations solely for convenience.
3. Designing a study to maximize potential benefits to participants while minimizing potential harms.
4. Allowing participants to withdraw from the study at any time without penalty.
, Correct Answer: C. Designing a study to maximize potential benefits to participants while minimizing
potential harms.
Rationale: The Belmont Report identifies three core principles: Respect for Persons, Beneficence, and Justice.
Beneficence involves an obligation to protect persons from harm by maximizing anticipated benefits and minimizing
possible risks of harm. Informed consent and the right to withdraw relate to Respect for Persons (autonomy). Fair
selection relates to Justice.
5. A researcher is planning a study that involves collecting de-identified survey data from healthy adult
nursing students about their study habits. The survey does not ask for sensitive information. Which level
of Institutional Review Board (IRB) review is most appropriate for this study?
1. Exempt review
2. Expedited review
3. Full board review
4. No IRB review is required
Correct Answer: A. Exempt review
Rationale: Exempt review is appropriate for studies that pose no more than minimal risk and fit into specific categories,
such as anonymous educational surveys or observation of public behavior without collecting identifying information.
Expedited review is for minimal risk studies involving some identifiable data or minor interventions. Full review is for
greater than minimal risk or vulnerable populations. All human subjects research requires some level of IRB
determination.
6. Which of the following research designs provides the strongest evidence for establishing a
cause-and-effect relationship between an intervention and an outcome?
1. Correlational design
2. Randomized Controlled Trial (RCT)
3. Case-control study
4. Descriptive cross-sectional study
Correct Answer: B. Randomized Controlled Trial (RCT)
Rationale: Randomized Controlled Trials (RCTs) are considered the gold standard for establishing causality. They
include three essential characteristics: manipulation of the independent variable (intervention), a control group, and
randomization of participants. These features minimize bias and confounding variables, providing the strongest
evidence for cause and effect among primary studies.
7. A qualitative researcher wants to understand the "lived experience" of mothers who have given birth to
extremely premature infants. Which qualitative methodology is most appropriate for this research
question?
1. Grounded Theory
2. Ethnography
3. Phenomenology
4. Historical Research
Correct Answer: C. Phenomenology
Rationale: Phenomenology is a qualitative research tradition rooted in philosophy that focuses on exploring and
understanding people's everyday life experiences (the "lived experience"). Grounded theory focuses on social processes
and generating theory. Ethnography focuses on understanding the culture of a group.
8. A researcher stands outside a grocery store and asks every fifth person who exits to complete a brief
survey about their dietary habits. What type of sampling method is this?
1. Simple random sampling
2. Stratified random sampling
3. Convenience sampling
4. Purposive sampling
Correct Answer: C. Convenience sampling
