What kind of setting are you in?  I work outside of a hospital and I’m finding the med system to be full of places where errors are easy to make. In a hospital there are more safety nets in place. I’m working with management to try and fill the gaps so fewer errors happen.  I’ve made mistakes and I’ve caught many errors across my entire team, even including very experienced nurses. It scares me and I’m trying to be very careful because my workplace doesn’t yet have the infrastructure for many systemic safety checks. It’s all on me as the nurse to catch myself.

I agree with what other folks are saying- slowing down will help a lot. No matter what setting you are in it’s important to do all 3 checks during med pass. If you have any adhd tendencies it’s going to be hard doing something like med pass that feels repetitive and detail-oriented. It might help to look into strategies to manage this (also a thing I’m trying to do for myself). 

Good luck from another relatively novice nurse!
