How clinical will affect my career

I dont know how much these two clinicals will affect my future as a nurse.  I knew before hand that the ICU was a place that I would like to work.  IF I were to leave the emergency department, the ICU is where I would start looking first.  I will definitely try to broaden my knowledge base in regards to more critical care information etc.  I want to try and organize an EKG class for the Emergency department. I believe that many of us could use it and it would greatly impact the of patients if we are more alert and aware of rhythms.  I think that too often we become reliant on the monitors and sometimes dont trust what the monitor is telling us.
