Welcome to AN! The largest online nursing community!
First of all.....we are not lawyers and it is against the Terms of Service to ask for legal advice....I know this isn't really advice.
You can't find concrete information because it isn't a concrete subject...... It depends.....If you are going around injecting potassium into the elderly to "ease their suffering" and they die that's first degree murder. It depends of the offense and depends if there was any criminal intent and it the offense is punishable by law.......like drug diversion and then infecting people with Hepatitis B (Hospital tech indicted in NH hepatitis C outbreak - News - Boston.com
) like in New Hampshire.
Some are criminal and receive criminal charges. Some are with the board and the board disciplines. Some are both and the parties may seek civil compensation.
A nurse should ALWAYS have malpractice insurance. If you need more concrete than this.....you will need to seek a lawyer that specializes in this field.
