Which action by the nurse demonstrates use of evidence-based practice (EBP) ?

A) Gathering equipment for a procedure
B) Documenting changes in a patient's status
C) Questioning the use of daily central line dressing changes
D) Clarifying a physician's prescription for morphine

The nurse who questions the daily central line dressing change is ascertaining whether clinical interventions result in positive outcomes for patients. This demonstrates EBP, which implies questioning why something is effective and whether a better approach exists. Gathering equipment for a procedure and documenting changes in a patient's status are practices that follow established guidelines. Clarifying a physician's prescription for morphine constitutes safe nursing care.
