I would hope not, many factors go in to this such as did patient suffer ill effects? is there a policy at your facility that requires double checking by another nurse? if the answer is no to all above
i would give it a 90% chance that there will be no ramifications from a simple med error.
I have never heard of complete loss of licensure for first-time medication errors. There's a wide range of discipline that usually comes before revocation of one's license, including fines, warnings, remedial education, limited license, supervised practice, probation, suspension, and voluntary surrender of licensure. To be perfectly honest, no one on these forums can tell you what will happen in your specific situation. Good luck to you!
