NCLEX-Style Questions on Planning a Nursing Study
Question 1
A nurse is conducting a literature review for a study. What is the primary purpose of this review?
A. To find potential funding sources
B. To identify gaps in current research
C. To recruit participants for the study
D. To develop a data collection tool
Answer: B. To identify gaps in current research
Rationale: The literature review helps the researcher identify gaps in existing studies, providing
a foundation for the new research question.
Question 2
Which of the following is an essential component of a research proposal?
A. A detailed budget plan
B. A clear statement of the problem
C. A list of potential participants
D. A timeline of events
Answer: B. A clear statement of the problem
Rationale: A clear problem statement guides the study’s direction and establishes its
significance.
Question 3
What is the primary ethical consideration in nursing research?
A. Cost-effectiveness
B. Informed consent
C. Research funding
D. Participant recruitment
Answer: B. Informed consent
Rationale: Informed consent ensures that participants understand the study's purpose,
procedures, risks, and benefits before agreeing to participate.
,Question 4
A nurse is using a qualitative research approach. What is a characteristic of this type of research?
A. Focus on numerical data
B. Use of statistical analysis
C. Exploration of human experiences
D. Emphasis on hypothesis testing
Answer: C. Exploration of human experiences
Rationale: Qualitative research seeks to understand human experiences and perspectives rather
than quantifying data.
Question 5
In a study examining the effects of a new medication on blood pressure, which type of study
design is the nurse implementing if participants are assigned to receive either the new medication
or a placebo?
A. Cohort study
B. Case-control study
C. Randomized controlled trial
D. Cross-sectional study
Answer: C. Randomized controlled trial
Rationale: A randomized controlled trial involves randomly assigning participants to receive
either the intervention or a control (placebo) to compare outcomes.
Question 6
Which of the following is a method of ensuring the reliability of a study's findings?
A. Using a small sample size
B. Conducting the study in a single setting
C. Standardizing data collection procedures
D. Allowing participants to self-select into groups
Answer: C. Standardizing data collection procedures
Rationale: Standardizing procedures minimizes variability and ensures that findings can be
replicated.
, Question 7
What is the main advantage of using a mixed-methods research approach?
A. It simplifies data analysis.
B. It allows for a comprehensive understanding of a research problem.
C. It requires fewer resources.
D. It minimizes bias in quantitative data.
Answer: B. It allows for a comprehensive understanding of a research problem.
Rationale: Mixed-methods research combines qualitative and quantitative approaches,
providing a fuller picture of the research question.
Question 8
Which sampling method involves selecting participants based on specific characteristics relevant
to the study?
A. Random sampling
B. Stratified sampling
C. Purposive sampling
D. Convenience sampling
Answer: C. Purposive sampling
Rationale: Purposive sampling involves selecting individuals who meet certain criteria, ensuring
that the sample is relevant to the research question.
Question 9
What is a potential disadvantage of convenience sampling in nursing research?
A. It allows for easy participant recruitment.
B. It may not represent the broader population.
C. It can be more cost-effective than other methods.
D. It provides rich qualitative data.
Answer: B. It may not represent the broader population.
Rationale: Convenience sampling can lead to biased results because it may not accurately
reflect the characteristics of the larger population.
