1. **What is the purpose of nursing research?**
- A) Develop new medications
- B) Generate knowledge to improve nursing practice
- C) Perform clinical assessments
- D) Conduct surgeries
- **Answer:** B) Generate knowledge to improve nursing practice
- **Rationale:** Nursing research validates and refines knowledge to enhance clinical
practice.[](https://www.studocu.com/en-us/document/texas-am-international-

2. **What is a key difference between quantitative and qualitative research?**
- A) Quantitative uses numerical data; qualitative explores experiences
- B) Quantitative is subjective; qualitative is objective
- C) Quantitative avoids data; qualitative uses statistics
- D) Both use identical methods
- **Answer:** A) Quantitative uses numerical data; qualitative explores experiences
- **Rationale:** Quantitative research tests hypotheses with numerical data; qualitative
research describes phenomena through subjective
data.[](https://www.assignmenthelp.net/module-1-quiz-nurs-5366)
3. **What is a randomized controlled trial (RCT)?**
, - A) A study observing natural occurrences
- B) A study randomly assigning participants to groups
- C) A study interviewing participants
- D) A study with no control group
- **Answer:** B) A study randomly assigning participants to groups
- **Rationale:** RCTs use random assignment to test interventions, reducing bias.
4. **What is a non-experimental research design?**
- A) Tests cause-and-effect relationships
- B) Describes phenomena without manipulation
- C) Uses random assignment
- D) Involves no data collection
- **Answer:** B) Describes phenomena without manipulation
- **Rationale:** Non-experimental designs (e.g., descriptive, correlational) observe without
intervening.
5. **What is the purpose of a literature review in research?**
- A) Develop new theories
- B) Identify gaps in existing knowledge
- C) Collect primary data
- D) Perform statistical analysis
- **Answer:** B) Identify gaps in existing knowledge
- **Rationale:** Literature reviews summarize current knowledge and identify research
gaps.[](https://onlinenursingpapers.com/nurs-3151-week-2-quiz-correct-answers/)
6. **What is a PICO question used for?**
- A) To design a study
, - B) To frame a clinical question for research
- C) To analyze data
- D) To implement interventions
- **Answer:** B) To frame a clinical question for research
- **Rationale:** PICO (Population, Intervention, Comparison, Outcome) structures clinical
questions for evidence-based practice.[](https://quizlet.com/564753749/nur-316-quiz-1-flash-
cards/)
7. **What is probability sampling?**
- A) Selecting participants non-randomly
- B) Selecting participants randomly
- C) Excluding participants
- D) Using only qualitative data
- **Answer:** B) Selecting participants randomly
- **Rationale:** Probability sampling ensures each participant has an equal chance of
selection, enhancing generalizability.[](https://www.stuvia.com/en-us/doc/783257/nurs-3151-

8. **What is a dependent variable?**
- A) The variable manipulated by the researcher
- B) The variable measured as the outcome
- C) The variable controlled in the study
- D) The variable not included
- **Answer:** B) The variable measured as the outcome
- **Rationale:** The dependent variable is the outcome affected by the independent
variable.[](https://www.studocu.com/en-us/document/oakland-university/research-basis-of-
