It sounds like an exciting opportunity for you. Don't be so anxious. They (employer) know the limitations of your scope of practice & the fact that you are a new grad. They should provide you with close supervision until you are competent & confident enough to work more independently. Because of your scope of practice, you will always have a qualified RN or physician as an immediate clinical supervisor. Because it is an urgent care center, they will rapidly transfer any patients experiencing truly serious or life-threatening situations. Mostly, you will be tending to cuts, bruises, N/V, dizzyness, etc. . nothing you can't learn to handle.
