Planning the care given by junior / non qualified staff, assessing care needs, supervising the use of equipment especially where things like moving patients is concerned, being alert to drug reactions, liasing with other allied health professionals, teaching and training students/juniors, risk assessing, being able to walk into a room and spot the patient who isn't doing well even when there are no obvious signs, and knowing what to do until the medical team arrive knowing when sitting down and talking is better than calling a junior doctor, when junior doctors come onto the wards keeping them from making mistakes by supporting them too so they feel comfortable checking with more experienced members of the team and not losing face... talking to doctors on behalf of patients who 'don't like to ask' and explaining the response in plain language, making sure a patient who is dying doesn't die alone if at all possible, its a long list Jack...ad they never stop learning..the trick is the good ones do it in such a way that you'd never see them think about it...and that is only a normal ward...I won't try to tell you what you have to do if you are an intensive care nurse or in A&E
