CNA knowledge exam prep with clear explanations, AI help and focused review.
Read full description
Prepare for the knowledge portion of your CNA exam with practice that connects care principles to everyday situations. Passy offers questions, clear explanations and AI Rescue to help you understand the reasoning behind an answer.
Support your nurse aide training with focused review of resident care, safety and professional responsibilities.
Review the knowledge behind safe care
Practice nurse aide concepts relevant to NNAAP preparation, including personal care, basic nursing skills, safety, infection prevention, psychosocial needs, communication and resident rights. Work through questions about observing, reporting and supporting residents within the nurse aide role.
Get help when a question doesn't click
AI Rescue offers help based on your answer:
• After an incorrect answer, tap "Why was I wrong?" for an explanation focused on your chosen answer.
• After a correct answer, tap "Challenge Me" for a similar question that checks your understanding.
When more than one response seems helpful, use the explanation to identify the care principle or responsibility the question is testing.
Know what to review next
See your practice accuracy by subject to help choose what to review next. Fix It brings missed questions back for another attempt, so you can return to the explanation and apply the care principle again.
