Which term is most closely associated with scientific principles in nursing?

• A. Data
• B. Rationale
• C. Problem
• D. Evaluation

Answer: (B)

Understanding how nurses justify actions with evidence and reasoning is tested here. A rationale is the explanation or justification for a chosen intervention, anchored in scientific principles, research findings, and clinical judgment. It shows why a particular care action is appropriate for the patient and how it relates to the observed data and desired outcomes. Data refer to the raw information collected during assessment, such as vitals or lab values; a problem is the identified nursing issue or diagnosis; evaluation is the process of determining whether the goals and outcomes were met after implementing care. Because a rationale explicitly links what is done to the underlying science and evidence, it’s the term that best aligns with applying scientific principles in nursing.
