Well, I know you are asking about patient related things, but I have some personal "safety tips" that I think are also essential.
#1 Be observant
. Once you practice and practice and hone this skill, it will save you from endless pitfalls of many kinds - patient deterioration you didn't pick up when you should have, body language of family members who are becoming frustrated, coworkers who mean to undermine you, managers who say one thing but mean another, an employment situation where you are not respected/valued. Know where things stand by noticing the details of people, surroundings, and situations.
#2 For the most part, keep your work and personal life separate other than pleasantries with your coworkers.
#3 (Once you get your feet soundly under you) HELP your coworkers whenever you reasonably can.
#4 Walk in the opposite direction of gossip; I don't care how frustrated you feel or what dumb thing you want to vent about. Don't do it, and don't stand around listening to it.
#5 Never argue with patients/families, and be careful not to inadvertently insult them. Practice your verbal, listening, and body language skills just as much as you practice anything else. Remain pleasant. Do your best to respect people. There are times when you will have to set limits or get help with a situation, but following this general rule will save you time after time.
#6 Be humble. Treat others the way you would want to be treated.
#7 Don't be reactionary/take everything as a personal insult.
That's enough to get you started at incorporating personal safety with regard to employment.
Lastly, an actual patient care tip: Any patient information that is collected by someone else: LOOK AT IT. It's very easy to forget about your vital signs or your blood sugars, etc. because these are often obtained and recorded by someone else. You have to know what these are!! Do not
assume that someone will report all abnormals to you. And even if they faithfully do, just knowing an abnormal here and there doesn't tell you anything about trends. Always, always make a point to synthesize the bigger picture.
Good luck to you ~
