In the Emergency Department (ED), which client should the nurse see first?

In the Emergency Department, the priority is to assess and manage clients based on the urgency of their conditions. A client with adrenal insufficiency presenting with weakness should be seen first as this could indicate a state of shock, which requires immediate attention to stabilize the client's condition. Weakness in adrenal insufficiency can progress rapidly to a life-threatening adrenal crisis. Choice A, a COPD client with a non-productive cough, may need treatment but is not immediately life-threatening. Choice B, a diabetic client with an infected sore on the foot, requires timely care to prevent complications but can generally wait for evaluation compared to the potential urgency of adrenal insufficiency. Choice D, a client with a fracture of the forearm in an air splint, is important but not as time-sensitive as a client potentially in shock.
