Frequently Asked Questions
Are these CCRN practice questions free?
Yes. Every practice question on this site is free to take. Each question includes four options, the correct answer, and a detailed rationale explaining why the answer is correct and why the distractors are wrong.
How hard are these compared to the real CCRN exam?
Our questions are calibrated to AACN’s CCRN test plan. Expect application- and analysis-level questions that test clinical judgment — not memorization. If you’re consistently scoring 80%+ on our quizzes, you’re ready for the real exam.
How many practice questions do I need before the exam?
Aim for 500-1,000 questions with full rationale review. Zero Deficit has 695+ curated questions across all 8 body systems, plus an AI question generator for unlimited drill on weak areas.
Can I retake the quizzes?
Yes — on the web these sample sets are static, but the full Zero Deficit app shuffles questions, tracks your accuracy per topic, and serves you more questions where you’re weakest.
Which body system quiz should I start with?
Start with your weakest system. If you don’t know, begin with Cardiovascular (17% of the exam) and Respiratory (15%) — the two largest sections.
