All of the problems/issues you have with med-surge, you will find elsewhere.
I started in CVICU, where nurses typically had one to two patients. The patients were still sometimes rude, with ridiculous demands and requests. And even though you had a small patient load, the patients were VERY sick, so there was definitely a lot of stress.
Fortunately, I have only run into a few rude MDs. And you will find plenty of them in CVICU because heart and lung transplant surgeons think very highly of themselves. You have to learn how to interact with them. But that can be said of any MD.
When I graduated from nursing school
a year ago, I turned up my nose at med-surge. It is now where I work. Do I think I'll be doing med-surge two years from now? No. But in the few months that I have worked in my unit, I have learned a lot about nursing, and a lot about following your gut when it comes to patients. These are very valuable things. I don't regret moving from CVICU to psychiatric nursing to med-surge.
No, I don't look forward to going into work each day. Actually, I ask every nurse I know if they look forward to going into work. Nobody answers yes! Everybody is stressed walking through those hospital doors. It's because you never know what you will be facing. But that is true of every specialty.
All nursing job carry stress and anxiety. But as time goes on, and you gain more experience, you will better learn how not to sweat the small stuff. When you are new, everything is potentially BIG.
Last night, I had to use my psychiatric nursing skills with a patient who suddenly went into near panic attack mode at 0330. I knew I wasn't going to call the MD for Ativan at that time, so I had to rely on my therapeutic nursing skills to prevent the situation from escalating. If I didn't have the psych background, I might have gotten anxious. But because I'd seen this behavior so many times in my previous psych patients, I knew what to do.
Please, please, please don't let this experience cause seeds of doubt to spread within you. Maybe med-surge isn't for you in the long run. But you will pick up valuable skills that you can use elsewhere.
And know that your feelings are normal.
