I received an email from the BON compliance officer about wanting me to participate in an investigation. When I spoke with them, they stated it was about a med error for suboxone many months prior that 15 other nurses at the facility made. They stated it was minor and wouldn't result in suspension or loss of license, just disciplinary action at the very most. I told them I was concerned and may seek legal counsel. They continued to state that it was minor and they just wanted to get my take on the situation regarding safe medication administration. They want to schedule a time to interview. Do I accept the interview or consult an attorney? Should I speak to my unit first? Nobody has written me up or informed me of any med error regarding this. I also have not heard of our entire unit being under investigation, either. I have only been a nurse for 3 years and have never had this happen. My state nursing board has a reputation for being notoriously aggressive. What's the best way to proceed?
