I guess every facility is different. Mine requied a 3 month internship in which we learned about all of the differnt drips and protocols. We are all ACLS certified and more than half of us have our PCCN. I have been a tele nurse for over 8 years and really like it. I get to see so many different types of patients from pregnant mommas to 100 year old grandmas. I have gained so much experience and would recommend it to anyone.
