Nurse Managers in LTC

I need to find my niche! I take so much pride in being an RN, but beat myself up all the time. I worked in a hospital for a few years as an RN. My last day I was treated poorly by having the worst assignment I could have. One patient ended up with a PE. I suspected it when I first saw him, but just kept an eye on him. The surgeon (one of the best) really didn't think it was a PE. I ended up calling him later in the day and the surgeon STILL didn't believe the patient had a PE, but wouldn't you know THE PATIENT HAD A PE! I kick myself for not using my instinct and pushing the surgeon earlier in the day. I had four other critical patients. I asked for help with this case load and got no where. I was determined to never go back as it was a floor having a hard time keeping help. I was told I gave the patient great care regardless of the PE, but I've yet to forgive myself for it. While he didn't present himself as a patient with a PE, I just had to wonder about the possibility. He ultimately went on a heparin drip and went home a few days later. THANK GOD!! I continued to work as an RN in a different area of the hospital, but always felt like a failure. I just kept being pulled in a million different directions - worse than usual.

I'm thinking about looking into a nurse manager position at a LTC facility. I'm going for my Masters now and will soon have it. While I'm thinking of different areas, I would love to work on a skilled nursing floor. I just lack some confidence. Maybe I should never get that involved in nursing again! I do know I'm not being fair to myself to be so hard on myself. I was given an assignment that turned bad and realize it could have been much worse. I've since left that hospital and work in a different area of nursing, but still miss being on a floor. I realize nurse managers have a lot of paperwork to deal with, but that doesn't bother me. I'm at a point that I'm considering leaving nursing all together or doing something like this. Any thoughts??
