A nurse manager mediates an argument between two staff members. Which of the following actions should the nurse take first to resolve the conflict?

The correct answer is B: Identify the problem. This should be the first step in resolving conflict because without clearly understanding the root cause of the argument, any further actions taken could be ineffective or even exacerbate the situation. By identifying the problem, the nurse manager can gather necessary information, perspectives, and context from both staff members involved. This will help in developing a targeted and appropriate resolution strategy. Evaluating results (A), implementing a resolution (C), and brainstorming solutions (D) should come after the problem has been identified to ensure that the chosen approach addresses the core issue.
