Ever since I floated to the ER as a nurse extern I've wanted to work there. But here is my concern...ER is the first line of defense for everyone coming into the hospital. You are exposed to everyone and everything before they are admitted to the floors. Do you ever worry about what infectious diseases you are coming in contact with before you even know what they have and what you might be taking home to your family? Do you ever think about bioterrorism? I can think of any of these things to worry about and it's keeping me from following my nursing passion. Is this realistic?
