Can I be a paramedic and Registered Nurse at the same time?

You would have to keep your scope of practices separate for each. When working as a Paramedic you could not do a skill or give a medication that you would as an RN. The Board of Nursing could also hold you accountable to a higher standard even though you are working as a Paramedic. Thus, you could lose your license very easily as an RN for a mistake made as a Paramedic. The Board would say "As an RN you should have known better". Several RNs do hold Paramedic certs but if working as an RN such as in Flight RN, the higher license of RN will be the one utilized. The exception would be a Flight Paramedic who just obtained the RN license and does not meet the requirements to be a Flight RN. In that situation they would remain working only under the scope of practice of a Paramedic or be asked to resign until they met the requirements of RN. Usually it is the situation of working with a lower license or certification that creates the problems and not working under the higher license while having another lessor certification. Check with the Texas Board of Nursing. You may also have to disclose any outside employment to all of your employers. No hospital will want you working a 24 hour shift as a Paramedic and coming straight to an RN job.

Yes, of course you could. Each skill would improve the other. It'd make you a very valuable paramedic and one hell of an ER nurse...if you wanted.

Yes you can be both. I used to know a man who was both.
