Maybe a silly question, but I know a couple of nurses who have not had any formal education or taken any specialized courses in legal nurse consulting, yet use the title Legal Nurse Consultant (and work as one as well, steadily).
Correct. RNs who work in this career can be addressed and use the title Legal Nurse Consultant (LNC) and are not required to have formal education or certification to practice as such. As I've stated in past threads, I always advise the RN to seek and receive formal education.
In essence, any nurse who was wanting to work as an LNC could apply that title to themselves without a specific set of credentials aside from a nursing license, correct?
Correct; full unencumbered and valid/current license to practice as a Registered Nurse and currently
practicing as Legal Nurse Consultant with or without formal education.
