Final answer:
The nurse manager is engaged in planning and organizing an in-service aimed at preventing readmissions following joint arthroplasty, which involves preparing the educational content and arranging necessary resources.
Step-by-step explanation:
The student's question asks which leadership task a nurse manager is performing when presenting an in-service about preventing readmission of clients due to complications following joint arthroplasty. The answer is that the nurse manager is performing the task of planning and organizing the in-service. This task involves creating an educational opportunity that aims to equip the nursing staff with knowledge and strategies to minimize complications and prevent readmission of patients, thereby improving care outcomes.
Effective planning and organizing of such in-services require understanding the educational needs of the staff, choosing relevant content, arranging for resources, and selecting appropriate teaching methods. This role does not directly pertain to delegating tasks, evaluating the effectiveness of the service, or inspiring and motivating the team, though it could indirectly contribute to these aspects.
