What You'll Do: The Cardiac Pre‑ and Post‑Procedure Unit provides comprehensive care for patients with heart failure, those recovering from CAS (coronary artery stenting) procedures, and individuals undergoing complex cardiac interventions. If your RN nursing license has been inactive, retired or lapsed for five years or more and you have not been licensed in another state during the last five years, successful completion of a Board approved refresher course is required prior to reactivating or reinstating your license.
