Which of the following could signify unprofessional conduct by an EMD?

Being argumentative or combative is a clear indication of unprofessional conduct in an Emergency Medical Dispatcher (EMD) context. An EMD's primary role is to provide calm and collected assistance during stressful situations. When an EMD displays a combative attitude, it undermines the effectiveness of their communication, disrupts the flow of the call, and can exacerbate the caller's distress. This behavior not only reflects poorly on the professionalism of the dispatcher but also has the potential to impact the quality of care provided to the patient.

In contrast, maintaining a respectful tone, actively engaging in calls, and demonstrating empathy are essential qualities for an EMD. These behaviors support clear communication, help reassure callers, and facilitate effective information gathering, ultimately leading to better outcomes for those in need of emergency assistance. The focus is on aiding the caller and managing the situation effectively, which cannot be achieved if the dispatcher is argumentative or combative.
