Final answer:
The nurse manager should recognize the defined behavioral norms and address the issue with those involved. Adopting a democratic leadership approach and involving the nurses in finding a solution will likely yield the best results.
Step-by-step explanation:
In assessing the staff's group dynamics, the appropriate action for the nurse manager would be to recognize that the group has already defined behavioral norms. This understanding suggests that certain behaviors have become entrenched and may be contributing to a negative atmosphere. It is crucial for the nurse manager to address the issue directly with those involved, rather than broadly implement punishments or ignore the input from the team. This approach aligns with the concept of a democratic leader, who seeks participation and consensus from the group before action.
Furthermore, by attending to the suggestions from the staff, the manager concurrently conveys respect and shows a willingness to involve the nurses in the solution. This participatory approach is more likely to result in effective and lasting changes in behavior. The manager should avoid actions that may seem authoritarian, such as disciplining the staff nurses who spoke out, as this could lead to further discontentment and disengagement.
