A nurse is implementing plan-do-check-act. Which of the following actions is the nurse going to perform?

A. Provide equal access to care: This is an ethical and policy-based goal but not a specific step in the Plan-Do-Check-Act (PDCA) cycle. B. Review data after changing practice: This corresponds to the "Check" phase of the PDCA cycle, where the outcomes of the change are measured and analyzed to determine effectiveness. C. Documentation of client care: While documentation is part of nursing practice, it is not specific to any phase in the PDCA cycle. D. Obtain certification in a specialty area: This is an individual professional development goal, not part of quality improvement methodology like PDCA.
