Step-by-step explanation:
The nurse manager's decision to study for an advanced degree in order to integrate the best current evidence with clinical practice reflects the QSEN competency of Evidence-based practice.
Evidence-based practice involves using the best available evidence, expertise, and patient preferences to guide decision-making in clinical practice.
