The CGRN exam is a computer-based test consisting of 175 multiple-choice questions. Of these, 150 are scored, and 25 are unscored pretest questions. The content is divided into three main domains:
- Domain 1: Gastroenterology (43%) - Focuses on the nursing care of patients with GI, pancreatic, biliary, and liver diseases.
- Domain 2: Endoscopy (43%) - Covers the endoscopy procedure process, including pre-procedure, intra-procedure, and post-procedure care.
