Final answer:
The first action of ED nurses when expecting numerous victims from a construction collapse is to assess the department for resources—staff, beds, and equipment—to effectively allocate resources for patient care.
Step-by-step explanation:
When an emergency department is notified about numerous victims being transported due to a construction collapse, the first action of the ED nurses should be to assess the department for resources—including staff, beds, and equipment. This is crucial to ensure a systematic approach to the incoming influx of patients, and to strategically allocate resources for optimal care. Once resources are assessed, other actions such as implementing a personnel recall system, discharging stable clients, and setting up a temporary morgue may follow depending on the severity and needs of the situation. The emergency department staff are trained to make fast, efficient decisions and to prioritize tasks in a way that maximizes their ability to provide urgent medical care.
