Interim Manager to Manager?

Hi everyone, I was wondering if I could get some advice from you. I was hired at my hospital in March of 2010 after working 11 months in a LTC facility as a new grad. After one year on the floor, my manager has left her position to work in an outpatient center in the hospital, and has asked me to become the interim manager of the unit.

After only one year of hospital nursing, I was both surprised and honored that my manager hand-picked me to lead the unit in the interim. I started on my own, as manager, last Monday, the 18th. It is quite challenging, as expected, but even more so because just 3 weeks ago, I was a staff nurse and worked on the floor with the nurses that now call me 'boss'.

Everyone, including my current director, is wondering if I will take the manager position permanently. This is making me think, because it was never my intention to take this position. I felt like I am too new of a nurse to get out of bedside nursing. However, everyone (mostly) thinks that I should take the manager position. I keep on going back and forth, even considering working PRN at a closer hospital to keep up with my bedside nursing. I am already having issues with some of 'my' staff, and it is challenging coaching and disciplining the older nurses on the unit (that I was actually afraid of when I started on the unit a year ago!), but when I go home at the end of the day, I feel like I could take this position on. I guess I just need feedback from those of you in management positions, and your thoughts.

Thank you for your time!
