I have been a nurse for almost 3 years, but will be working my first hospital floor job since becoming a nurse. I will be working on a heart failure floor with med surg overflow. I'm really excited and have been reading up on cardiac diagnoses, meds, interventions, and so on..... I've been getting a little overwhelmed thinking about all of the possible issues I may encounter!!! Does anyone have any suggestions of meds or tests or anything that I should know like the back of my hand? Or any suggestions in general for a newish nurse working in cardiac? Thanks!!
