A key function of a study’s methodology is to

A.

Determine the hypotheses that will be tested in the study.

B.

Exercise control over contaminating factors in the study environment.

C.

Identify grants and other funding sources for conducting the study.

D.

Protect the rights of the study’s participants.

Answer and Explanation

The Correct Answer is B

In research, the methodology is the structured plan that outlines how a study will be conducted. It details the research design, data collection methods, sampling, and analysis procedures.

Rationale for correct answer:

B. Exercise control over contaminating factors in the study environment: Methodology includes strategies to minimize bias and control extraneous variables to ensure that results are accurate and valid.

Rationale for incorrect answers:

A. Determine the hypotheses that will be tested in the study: Hypotheses are formulated before the methodology section is developed. The methodology tests the hypotheses, but determining them is part of the research question formulation stage.

C. Identify grants and other funding sources for conducting the study: Securing funding is part of the research planning process, not the methodological framework.

D. Protect the rights of the study’s participants: Protecting participants’ rights is part of research ethics and is overseen by Institutional Review Boards (IRBs), not directly a function of the methodology section (though ethical procedures are described within it).

Take home points

  • Methodology ensures control of variables and consistency in how research is carried out, which improves validity and reliability.
  • While ethics and funding are important, methodology’s main role is to describe how the study is conducted to answer the research question accurately.

Correct Answer is C

Explanation

Qualitative research is used to explore and understand human experiences, emotions, perceptions, and meanings. Unlike quantitative research, which focuses on numbers and measurable data, qualitative research investigates the "why" and "how" behind behaviors, feelings, and decisions.

Rationale for correct answer:

C. A study examining client reactions to stress after open heart surgery: This is qualitative because it focuses on subjective reactions, emotions, and coping strategies. Such data cannot be fully captured through numbers but require descriptive, narrative accounts.

Rationale for incorrect answers:

A. A study measuring nutrition and weight loss or gain in clients with cancer: This is quantitative research because it involves objective measurement of physical parameters (weight, nutrient intake) and statistical analysis, not subjective experiences.

B. A study examining oxygen levels after endotracheal suctioning: This also falls under quantitative research since oxygen levels are numerical, measurable values.

D. A study measuring differences in blood pressure before, during, and after a procedure: This is a quantitative study as it involves measurable physiologic data (blood pressure readings).

Take home points:

  • Qualitative research = exploring lived experiences, perceptions, and emotions; quantitative research = measuring numerical variables.
  • Research design must match the research question-subjective experiences that require qualitative methods.

Correct Answer is B

Explanation

When nurses read published research, their role is to critically appraise the study. That means evaluating the study’s quality, relevance to their patients, feasibility of applying the findings in their setting, and whether the evidence fits with patient values and resources.

Rationale for correct answer:

B. Evaluate whether the findings are applicable to the nurse’s specific clients: A key nursing responsibility is to determine external validity - are the study population, setting, interventions, and outcomes similar enough to your clients that the findings can be safely and effectively applied?

Rationale for incorrect answers:

A. Assume that the research was properly conducted since it has been published: Publication (even peer review) does not guarantee methodological rigor or applicability. Studies may have bias, small samples, conflicts of interest, or be published in low-quality journals.

C. Implement the research findings if at least two studies have shown the same results: Consistency across studies is important, but implementation requires assessing study quality, totality of evidence (systematic reviews/meta-analyses are stronger), clinical significance, feasibility, and patient preferences.

D. Request the raw data from the researchers so that the nurse can analyze the statistics again: Re-analyzing raw data is not a routine nursing responsibility and is often impractical (data access, time, statistical expertise, confidentiality). Nurses should critique methods and report analyses instead.

Take home points

  • Always critically appraise research for validity and applicability before applying it to your patients.
  • Relevance to your specific patient population and clinical setting is as important as the study’s reported results.
