Our practice questions are based on the official CNA exam questions that have appeared on past exams. We have seen many real CNA tests and constantly update questions and rationales as regulations change.
Although the National Nurse Aide Assessment Program (NNAAP®) doesn't make the official CNA tests public, we can confidently say that we know what NNAAP wants to ask on the exam and what topics they want to test you on.
It's very likely that the questions you'll get on the actual exam will be about the same concepts, however, you should be prepared that the questions on the official test will be worded differently. Make sure you read the question carefully and pay special attention to the ones containing a negation or "all/none/some/any of the above" clauses.
