As an art, nursing relies on knowledge gained from practice and reflection of past experiences. As a science, nursing draws on
Correct Answer: A
Rationale: Nursing as a science draws on scientifically tested knowledge applied in practice e.g., evidence from randomized trials on wound dressings informs care. This ensures interventions are reliable, not anecdotal, blending art's intuition with science's rigor. Physician-generated research is too narrow; nursing science includes broader sources (e.g., nurse-led studies). Experimental research (e.g., trials) is one method, but not all knowledge is experimental observational studies also contribute. Non-experimental research alone (e.g., surveys) lacks the full scope of tested application. Scientifically tested knowledge encompasses diverse, validated findings, grounding nursing in evidence-based practice, making it the comprehensive basis for its scientific dimension.
