Final answer:
The nursing manager is in the Integrate stage of change, focusing on solidifying the merged nursing units' changes and resolving any remaining issues through staff feedback.
Step-by-step explanation:
The stage of change the nursing manager is encountering, whereby they are inquiring about how the changes are working and if any barriers remain, is commonly known as the Integrate stage. This phase involves determining how effectively the new processes are being assimilated into daily operations and seeking feedback to address any ongoing issues. The goal is to solidify the changes and ensure they are sustainable and productive in the long term. This dialogue and remediation align well with concepts of buy-in and continuous improvement, often seen in organizational change management and quality assurance strategies.
