Any one out there involved in Telephone Triage Nursing? I am interested in TTN and would like information and insite into this area of nursing. I have 15 years experience in nursing, I am an RN, BSN, CEN and have the following certifications. ACLS, TNCC, ENPC, PALS, BLS, and (CEN) Board Certification in Emergency Nursing. Do you have to be certified to be a Telephone Triage Nurse? Where are the jobs in Oklahoma? How do you go about getting a TTN position? Thank-you for your input.
