When I was in nursing school
, my professors told us that the most important factor in a new nurse's transition into a job was the nurse's aides. They were right. Whether they are call aides, techs or whatever, it is the support people who can "make or break" a new nurse. It is difficult to take orders from a (usually) younger person who doesn't even know where the extra stash of alchol preps are, yet makes 3 times an aide's salary. Give them the respect they deserve and help them whenever you can.
It is important to choose the right unit in which to begin a career. A busy, short-staffed unit teaches time management, but at what cost? Find a unit that interests you and find a mentor to guide you. Know your limits and follow them.
Nurses are taught leadership and management, but a new nurse will find it difficult to be an agent of change in an established unit. Don't try to "fix" the problems too soon, even when you are right. Be a professional nurse by setting an example for others. Maintain your standards, do what you know to be right, and work diligently to improve your clinical expertise.
