Which of the following is not listed as a basis for nursing care?

• A. Best available research evidence
• B. Patient preference
• C. Administrative policy alone
• D. Clinical expertise

Answer: (C)

Decisions in nursing care should be based on evidence-based practice, which combines the best available research evidence, patient preferences and values, and the clinician's expertise. Administrative policy alone does not constitute a basis for clinical decisions; it guides how care is delivered and ensures standards, but it does not by itself address individual patient needs or reflect current evidence or professional judgment. Therefore, this option is not listed as a basis for nursing care. The other elements fit the model: up-to-date research informs what interventions are most effective, patient preferences ensure care aligns with what matters to the patient, and clinical expertise applies professional judgment to tailor interventions.
