Start testHow these CGRN practice tests match the real exam
The real Certified Gastroenterology Registered Nurse (CGRN) Exam has 175 questions and a 180-minute time limit. Question types: Multiple choice (four options, one correct answer). Each practice test here uses the same question formats, so you get used to how CGRN questions are asked before test day.
The tests draw on every CGRN content area, weighted like the official outline:
- General Nursing Care (about 21% of the exam)
- Gastroenterological Procedures (about 35% of the exam)
- Patient Care Interventions (about 25% of the exam)
- Environmental Safety, Infection Prevention and Control (about 19% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
