Nursing education combines nursing practice with an entirely different profession - education - that also has its own body of knowledge, principles & practices as well a daunting amount of regulatory must-haves. A nurse educator must be able to meet the requirements of both professions simultaneously in the same way that a nurse administrator must meet fiduciary responsibilities in accordance with the general principles of accounting and governance.
I am a nurse educator. It is a deliberate choice for which I have prepared myself in terms of education, training & practice. I'm very provoked whenever I encounter the belief that education is a 'fall-back' that anyone can do without any additional formal preparation. Effective teaching is not a happy accident. Online instruction is much more complex and challenging than classroom teaching, particularly in areas of student engagement and interaction. Most schools that have online classes will provide an orientation for new faculty, but this usually only includes use of the course materials/software and their policies & procedures.
You may be very surprised at the very low salary & lack of benefits associated with adjunct (part time, pay-per-course) teaching.
