Hey! First off, I think you should def do nursing! If you ever want a rewarding career that really makes a difference in peoples lives, then nursing is for you! :) Second, I have worked in the ER and have dealt with many many anxious, rude, and angry families. The BEST way to handle is actually pretty simple. LISTEN is the first step. Most of the time the families are afraid for their family member and just feel like the whole hospital staff is just too busy to just hear their worries. First listen, and then if you don't know how to help.. then ask how can I help you? What can I do for you? Are there any specific questions you need answered? If you cannot answer them then kindly let them know that you will send someone in who will be able answer. once you are a nurse you might be able to answer the questions and simple reassure them that at this hospital they are getting the BEST care and that you will do anything in your power to help. Seeing your family member suffer is a very scary time. Most of the time they really just need someone there for them. Does this help?? let me know if you need anything else!! Or more questions or need me to elborate :)
