Final answer:
The primary role of the ambulatory care nurse leader in the task group's termination phase is to review the group process and its achievements while making recommendations for the future.
Step-by-step explanation:
As the ambulatory care nurse leader of a task group approaches the final termination phase after completing the assigned tasks, the primary role is to Review the group process and achievements. This entails discussing the Observations, Outcomes, and providing guidance on Next Steps. The nurse leader should evaluate the overall performance of the task group, acknowledge the group's collaborative effort, and discuss the successful completion of items such as the accurate recording of the procedure name, confirmation of needle, sponge, and instrument counts, proper labeling of specimens, and addressing any equipment issues. Moreover, this provides a crucial opportunity for the nurse leader to make recommendations about future projects based on the group's experience and performance during the completed project.
