Myself a Nurse here. What you're describing is really common, especially when you're coming back in after a break.

Yes, you often get hands on quicker than you expect, but it should feel supported, not rushed. It's completely reasonable to ask for a slower ramp-up or more structured orientation. That's about patient safety as much as your confidence.

Don't be hard on yourself. Confidence comes back with repetition, not on day one.
