FAQ: Body Systems and Common Conditions on the CNA Exam
How many body systems and common conditions questions are on the actual NNAAP exam?
The NNAAP written exam has 60 scored questions distributed across eight content areas. Body Systems and Common Conditions is one of the most heavily tested categories, with several questions appearing on every form of the exam. Drilling these questions repeatedly until you can explain why each correct answer is correct is the best way to lock in the material.
What should I do if I miss several questions on this body systems and common conditions practice test?
Re-read the corresponding free study guide (linked above and below) before retaking the test. Take notes on the exact concept you missed — for example, 'I confused contact and droplet precautions' — and review the explanations until the pattern is clear. Most students need 2 to 3 cycles of test, review, and retake before consistently scoring above 80%.
Are these questions identical to the real CNA exam?
No. The actual NNAAP, Prometric, Headmaster, and PSI exams are confidential and only the official testing vendors have access to live items. Our questions are written by us to mirror NNAAP style, difficulty, and content distribution based on the publicly available NNAAP content outline. Performing well here is a strong predictor of passing the real test.
Do I have to pay or sign up to take this practice test?
No. Every practice test, study guide, and resource on freecnatraining.org is 100% free, with no signup or paywall. Most other CNA practice test sites charge $30 to $100 per month for access; we are funded by our nursing-school directory and keep the study material free for students.
