For example, if some SEVERE devastating "end of the world" weather tragedy (earthquake, tsunami, hurricane) were to occur and there were numerous people in need of serious medical attention. Assuming medical supplies were available in their disposal, would a registered nurse with 5 years of experience in the ER or ICU be able to treat the the people on their own?
The reason for my question is that I have been watching a lot of medical television series (bad reference for information, please excuse me) and there was an episode where a nurse is checking out a victim's gunshot wound in a surplus store filled with supplies during a robbery. The surrounding spectators tell the civilian RN to do something while the wounded victim is bleeding everywhere. The nurse always responds "he needs a doctor." The nurse is unable to extract the wound by themselves?
Sorry if I sound misinformed. Could any other fields hold their own without being a doctor or consultation from one? (PA, NP, EMT, etc.) Not only limited to gunshot wounds, but other severe injuries, diseases, sickness etc.
Keep in mind, this is a hypothetical end of the world type of event, so losing your license/lawsuits do not really apply. Just people who are in dire need of your assistance in a rural region.
