Which action is a potential contributor to staff post-traumatic stress disorder (PTSD) during a mass casualty assessment?

Working continuously without any breaks can significantly contribute to staff post-traumatic stress disorder (PTSD) during a mass casualty assessment. When staff members are engaged in high-stress situations without the opportunity to take breaks, they can become overwhelmed both physically and emotionally. This lack of respite prevents individuals from processing their experiences and can intensify the symptoms associated with PTSD.

Continuous work can lead to exhaustion, heightened anxiety, and a sense of helplessness as individuals grapple with the emotional weight of the situations they are dealing with. Without breaks, staff may not have the chance to engage in self-care or reflection, which are essential for coping with the intense stress of mass casualty scenarios.

In contrast, actions like encouraging team members and discussing feelings can foster a supportive environment, which can mitigate stress and help in processing traumatic experiences. Working less than 12 hours may not necessarily contribute to PTSD, as shifts can vary in length without inherently increasing stress. Therefore, while all actions may have different impacts, continuous work without breaks stands out as a significant risk factor for developing PTSD among staff in such critical situations.
