CGRN EXAM STUDY GUIDE 2026–2027

Description

Pass the CGRN Exam with Confidence: Your Complete 2026–2027 Study Guide by Sara Giovani

You’re an experienced GI nurse, and you know your unit. The CGRN exam tests something more: 175 questions on clinical judgment, prioritization and safety across every corner of gastroenterology nursing. You don’t need a stack of books and scattered notes. You need one clear, organized guide that shows you what matters and gives you plenty of realistic practice.

This all-in-one study guide is built around the four content domains of the ABCGN examination. You study what the exam actually tests, in the same proportions it tests it.

What’s inside:

• 599+ practice test questions (664 in total): three full-length practice tests that mirror the real exam’s length and domain balance, plus four focused domain drills.
• A clear explanation for every question, so you learn why the right answer is right and why the others are wrong.
• 20 review chapters covering GI anatomy, assessment, disorders, pharmacology, endoscopic procedures, sedation, patient care, endoscope reprocessing, infection prevention and safety.
• 48 charts, graphs and diagrams that make hard concepts stick: the sedation continuum, the electrosurgery circuit, the 11 steps of scope reprocessing, ulcer bleeding risk, the biliary tree and more.
• 18 clinical case studies that train the prioritization skills the exam rewards.
• A chapter on real-world problems and solutions: poor bowel prep, sedation events, reprocessing errors, scope shortages and more.
• Exam tips and key-point summaries in every chapter, to help you avoid common traps.
• Fast-review tools: 100 high-yield facts, a glossary, drug and lab quick references, readiness checklists, flashcards and an exam-day checklist.

Study smarter, not longer. An eight-week study plan, answer sheets, score trackers by domain and time-management strategies help you find your weak spots early and walk into the testing center prepared.

Who this book is for: registered nurses preparing for the Certified Gastroenterology Registered Nurse (CGRN) exam, and any GI or endoscopy nurse who wants a thorough, practical review of the specialty.
