Midterms Exam Review (Qns & Ans)
2025
1. Which type of research design is most suitable for examining
cause-and-effect relationships?
- A. Cross-sectional study
- B. Cohort study
- C. Randomized controlled trial (RCT)
- D. Case-control study
- ANS: C. Randomized controlled trial (RCT)
©2025
, - Rationale: RCTs are considered the gold standard for
determining cause-and-effect relationships due to their
randomization and control of variables.
2. In evidence-based practice, which level of evidence is
considered the highest?
- A. Expert opinion
- B. Randomized controlled trials
- C. Case studies
- D. Systematic reviews and meta-analyses
- ANS: D. Systematic reviews and meta-analyses
- Rationale: Systematic reviews and meta-analyses synthesize
data from multiple studies, providing a higher level of evidence
than individual studies.
3. What is the primary purpose of a literature review in a
research study?
- A. To collect new data
- B. To provide a background and rationale for the study
- C. To test the research hypothesis
- D. To analyze research findings
- ANS: B. To provide a background and rationale for the
study
©2025
, - Rationale: Literature reviews help researchers understand
existing knowledge and identify gaps that the current study aims
to address.
Fill-in-the-Blank Questions
4. The process of critically appraising a research article involves
evaluating the __________, __________, and __________ of the
study.
- ANS: validity, reliability, applicability
- Rationale: Critical appraisal includes assessing the validity
(accuracy), reliability (consistency), and applicability (relevance)
of the research findings.
5. In evidence-based practice, __________ refers to integrating
the best available research evidence with clinical expertise and
patient values.
- ANS: evidence-based practice (EBP)
- Rationale: EBP involves combining research evidence,
clinical expertise, and patient values to make informed healthcare
decisions.
6. A __________ is a type of research that involves a detailed
examination of a single subject or small group of subjects.
- ANS: case study
©2025
, - Rationale: Case studies focus on in-depth analysis of
individual cases or small groups to provide detailed insights.
True/False Questions
7. True or False: Qualitative research primarily focuses on
numerical data and statistical analysis.
- ANS: False
- Rationale: Qualitative research focuses on exploring
phenomena through non-numerical data, such as interviews and
observations.
8. True or False: Informed consent is not necessary for
participants in research studies involving minimal risk.
- ANS: False
- Rationale: Informed consent is required for all research
participants, regardless of the level of risk involved.
9. True or False: A hypothesis is a statement that can be tested
through research.
- ANS: True
- Rationale: A hypothesis is a testable statement that predicts
the relationship between variables in a research study.
