Start testHow these CRNI practice tests match the real exam
The real Certified Registered Nurse Infusion (CRNI) Exam has 140 questions and a 150-minute time limit. Question types: Four-option multiple choice (120 scored and 20 unscored pretest items); recall and application items. Each practice test here uses the same question formats, so you get used to how CRNI questions are asked before test day.
The tests draw on every CRNI content area, weighted like the official outline:
- Principles of Practice (about 29.2% of the exam)
- Access Devices (about 32.5% of the exam)
- Infusion Therapies (about 38.3% 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.
