The stress level depends what unit you work on. If you’re in ICU, it's usually critical situations that you're in, however if you’re in the general floor, most patients are stable so it's usually low stress unless you have many patients.
Overall, it can be stressful in the beginning, but once you get your muscle memory going, it get easier. Plus you're not the only nurse in your floor so you'll have folks help you out.
I would say the stress is worth it and could be very rewarding!
Best of luck!
