What are common CNA exam mistakes?
Updated September 3, 2026
Passing the CNA exam requires more than memorizing facts; it demands careful strategy. Many candidates lose points due to preventable mistakes. Here are the most common CNA exam mistakes and how to avoid them.
1. Rushing Through Questions
One of the biggest mistakes is rushing. The CNA written exam is timed, but not excessively. Reading each question slowly and thoroughly is essential. Look for keywords like "except," "not," or "first" that can change the answer.
2. Overlooking Safety and Infection Control
In both written and clinical skills tests, safety and infection control are heavily weighted. Forgetting to wash hands, not wearing gloves, or improperly disposing of materials are common errors. Always prioritize patient safety and follow standard precautions.
3. Poor Time Management
Failing to pace yourself can result in unanswered questions. Practice with timed tests to improve your speed. If you get stuck on a question, mark it and move on, then return if time allows. For the skills test, practice each skill within the allotted time.
4. Ignoring the Skills Checklist
During the clinical skills test, many candidates skip steps or perform them out of order. Each state uses a checklist; know what evaluators look for. For example, when taking vital signs, always state the normal range and record accurately. Practice with a CNA skills test practice PDF to master the sequence.
5. Not Understanding Medical Terminology
Misinterpreting terms like "ambulate," "supine," or "NPO" can lead to wrong answers. Build your vocabulary by reviewing common CNA terms regularly.
6. Neglecting Rest and Nutrition
Arriving on test day exhausted or hungry impairs focus. Get a full night's sleep, eat a balanced meal, and stay hydrated. Anxiety can also cause careless errors; take deep breaths and stay calm.
7. Skipping Practice Tests
Many candidates fail because they never take a free CNA practice test. Practice tests help you become familiar with the format and identify weak areas. Aim to complete at least several practice exams before the real test.
