Tuesday, June 15, 2010

Georgetown, SC— Georgetown Memorial Hospital Critical Care Unit (CCU) Clinical Director Melanie Johnston, RN, BSN, CCRN-CMC and CCU Education Specialist Rebecca Griggs, RN, BSN, CCRN-CMC have received their Cardiac Medicine Certification (CMC) through the American Association of Critical Care Nurses, becoming the 12th and 13th nurses in the state of South Carolina to receive this designation.

The CMC certification was established in 2005 for critical care nurses who provide care to acute and critical adult cardiac patients. Previously, Johnston and Griggs  achieved their specialty certification in Adult Critical-Care Nursing (CCRN). This allowed them to test for the CMC subspecialty certification. The CMC exam is designed for certified nurses currently involved in CCU and other cardiac medical units such as the Intensive Care Unit (ICU), Cardiac Catheterization labs, Electrophysiology, and Interventional Cardiology.
