Final answer:
Effective change management is demonstrated by a nurse manager's focus on inclusivity, alignment with institutional values, and having administration support.
Step-by-step explanation:
The statements by the nurse manager that would demonstrate effective change management include: "In order for this plan to work, everyone must agree to participate." and "We cannot lose sight of the mission and values of our institution as we begin to integrate these changes." and "Although this task is going to be difficult, we have the full support of our hospital administration."
These statements embody a proactive and inclusive approach, align with the core values and mission of the institution, and communicate the support from higher management which is essential for the successful implementation of change.
