Explanation

The defining feature of scientific research is that it is empirical, meaning it is based on direct observation and evidence gathered from the real world.
This characteristic ensures that scientific knowledge is grounded in objective, verifiable data rather than just theory, logic, or opinion.
While other options are related to research, 'empirical' is the most fundamental attribute that makes a study scientific.
Source SRC_1 explicitly states that empiricism, being based on observable and measurable data, is a key characteristic of scientific methods.

Option A: Experimental research is a specific type or method of conducting research, not the fundamental characteristic of all scientific inquiry. Many scientific studies, like observational or descriptive research, are not experimental.
Option B: Historical research is a specific methodology focused on studying past events. It is a category of research, not a universal characteristic that defines all scientific research.
Option D: Theoretical research focuses on developing concepts, models, and theories. While crucial for science, a theory itself is not the research; it is the empirical testing of that theory that constitutes scientific research.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Core Characteristics of Scientific Research as background academic context rather than a clinical decision trigger.
Understanding that research is empirical is the foundation of Evidence-Based Practice (EBP) in nursing. Nurses must be able to identify and trust research that is based on collected data, not just expert opinion.
This knowledge helps nurses critically appraise research articles, questioning how the data was collected and whether the evidence robustly supports the conclusions before applying findings to patient care.
What if a new wound care technique is proposed based on theory alone? A nurse grounded in the principles of scientific research would know to look for empirical studies (e.g., clinical trials) that have tested the technique's effectiveness and safety before adopting it.

How to Approach the Question

First, analyze the question. It asks for the 'main' or most fundamental characteristic that applies to all scientific research.
Next, evaluate each option. Think about whether the term describes a universal principle or a specific type of research.
Recognize that 'Experimental' and 'Historical' are specific categories or methodologies of research, not a characteristic of all research.
Consider 'Theoretical' versus 'Empirical'. Theories are ideas, while 'empirical' refers to testing ideas with observable evidence. Science is defined by the testing, not just the ideas.
Conclude that 'Empirical' is the most encompassing and fundamental characteristic that defines research as scientific.
