How is a hypothesis related to a theory?
A theory can determine the validity of a hypothesis.
A theory can be used to evaluate the merit of a hypothesis.
Hypotheses must be consistent with an existing theoretical framework.
Hypotheses can be developed in the absence of a theoretical framework.
The Correct Answer is C
Choice A rationale
Theories are broad, organized systems of ideas intended to explain a phenomenon, but they do not act as the ultimate arbiter of truth for a hypothesis. Instead, empirical evidence gathered through testing a hypothesis determines its validity. A theory provides the landscape for exploration, but it cannot unilaterally validate a specific prediction without the rigorous application of the scientific method and data collection to support or refute the specific hypothesis being tested.
Choice B rationale
While a theory provides a context for understanding results, the merit of a hypothesis is typically evaluated through experimental design, statistical analysis, and reproducibility. Merit is found in the hypothesis's ability to be falsified and its clarity. A theory might suggest why a hypothesis is important, but the evaluation of the hypothesis itself is an empirical task. The relationship is more about guidance than a direct evaluation of the hypothesis's intrinsic scientific quality.
Choice C rationale
A hypothesis is a specific, testable prediction that should logically flow from a theoretical framework. Theories provide the conceptual underpinnings that allow researchers to make educated guesses about relationships between variables. By ensuring consistency with a theory, researchers can build a cohesive body of knowledge where findings contribute to refining or expanding the existing theory. This deductive approach ensures that the research is grounded in established scientific principles rather than isolated observations.
Choice D rationale
Developing a hypothesis without any theoretical framework often leads to aimless data collection or "fishing expeditions" that lack scientific rigor. Without a theory, there is no logical basis for predicting how variables might interact or what the outcomes might signify. Theoretical frameworks are essential because they define the concepts and the proposed relationships that the hypothesis seeks to test. Most robust scientific inquiries start with a theory to provide direction and meaning to the study.

Correct Answer is A
Explanation
Choice A rationale
Small sample sizes significantly increase the risk of sampling error, where the participants do not accurately represent the diverse characteristics of the larger target population. In quantitative research, a representative sample is necessary to generalize findings. When the sample is too small, outliers or unique individual characteristics can disproportionately influence the results, leading to biased conclusions. This lack of representation undermines the external validity of the study and limits its clinical applicability to broader groups.
Choice B rationale
Loss of confidentiality is a risk related to data management and ethical conduct rather than the size of the sample itself. While a very small sample in a local setting might make individuals easier to identify, confidentiality is protected through de-identification and secure storage protocols. Sample size concerns primarily focus on the statistical power and representativeness of the data. Ethical breaches regarding privacy can occur in large studies just as easily if the researcher fails to follow protocol.
Choice C rationale
Subject interaction, or contamination, occurs when participants communicate and influence each other's responses or behaviors during a study. This is an issue of internal validity and experimental control rather than a direct consequence of sample size. While interaction might be more noticeable in smaller groups, it is managed through study design and blinding. The primary scientific concern with small numbers remains the inability to achieve statistical significance or to reflect the population variance accurately.
Choice D rationale
Regression toward the mean is a statistical phenomenon where extreme scores tend to be followed by scores closer to the average upon retesting. This occurs regardless of sample size, although it can be more visible or problematic in certain longitudinal designs. It is not a risk specifically heightened by having few participants. The fundamental scientific problem with small samples is the high margin of error and the inability to capture the true diversity of the population being studied.
Correct Answer is B
Explanation
Choice A rationale
The primary goal of nursing research is not to move into other disciplines but to strengthen the unique foundation of nursing itself. While interdisciplinary collaboration is valuable, expanding the scope of practice into other fields can lead to role confusion and legal issues. Research should clarify what nurses do uniquely rather than attempting to perform the duties of other healthcare providers. The focus remains on improving patient care within the established legal and professional nursing framework.
Choice B rationale
Research is essential for developing a unique body of knowledge that defines nursing as a distinct profession and science. This specialized knowledge allows nurses to provide care that is based on proven evidence rather than just tradition or intuition. By generating this evidence, nursing can justify its practices, improve patient outcomes, and establish its own theoretical foundations. This scientific growth is what elevates nursing from a technical vocation to a respected, autonomous, and scholarly health profession.
Choice C rationale
While following evidence-based practices derived from research can indirectly reduce liability by ensuring standard care, this is not the primary significance of nursing research. The goal of research is the advancement of health and the improvement of care delivery, not merely legal protection. Reducing liability is a risk management benefit, whereas research is focused on the pursuit of truth and the optimization of clinical interventions to benefit the patient and the healthcare system.
Choice D rationale
Specifically defining responsibilities is more the role of regulatory bodies and state boards of nursing than research. While research informs what those responsibilities should be based on efficacy, the act of defining them is an administrative and legal process. Research provides the "why" and "how" of nursing care, whereas professional organizations use that data to set the "what" of practice. The significance lies in the knowledge gained, not the administrative definitions created.
