Those questions are the very legal definition of reckless homicide. Have you ever taken a legal class even as an elective in college? If you have....then you would better understand this is not even hard.
This very definition has appeared in numerous articles on the topic as journalists have attempted to explain why THIS nurse, over others that have made medication errors and have not been charged, is being charged.
They are going to get a legal nurse consultant for her trial that is going to tell the jury that every nursing program teaches the five rights of medication and this is a universal standard. She will advise the jury every step RV bypassed for personal convenience. She is also going to advise the DA to have copies of all of her competencies pulled where she was checked off on medication administration, Pyxis training, pitfalls for avoiding errors in pulling the wrong medication, etc. They may even go as to so far as to get her college transcripts, her courses in pharmacology, anything tied to her certification, anything they can use to prove she was taught better.
If they move forward with the charges, there is no way they are not going to find her guilty. Her best bet is to keep the money she has got for GoFundMe, try to cut a plea deal to avoid a felony, give up her nursing license, and use that money to go back to college and major in something else.
