Feeling that mix of nerves and excitement as your CNA exam date approaches? You’re not alone. Every nursing assistant has stood exactly where you are, wondering what questions will appear on that crucial test. The good news? Understanding exactly what to expect can transform that anxiety into confidence. This comprehensive guide breaks down every aspect of the CNA exam questions, from the written portion to the hands-on skills evaluation, so you can walk in fully prepared and ready to prove your competence.
Understanding the CNA Exam Structure: A Two-Part Challenge
Think of your CNA certification exam as a two-part challenge designed to verify your knowledge and skills from every angle. The first part is the written examination, typically consisting of 60-70 multiple-choice questions you’ll complete on a computer or with paper and pencil. The second portion is the clinical skills test, where you’ll perform 3-5 randomly selected skills for an evaluator.
You must pass both parts to earn your certification. The written portion usually has a 2-hour time limit, while the skills test takes about 30 minutes total. Each state has slight variations, but the core structure remains consistent nationwide.
Clinical Pearl: The exam tests not just what you know, but how you apply that knowledge in patient-centered scenarios. Understanding this philosophy is key to success.
A Deep Dive into CNA Written Test Questions
The written portion goes beyond simple memorization. These questions often present realistic clinical scenarios that require critical thinking and judgment. You’ll notice a strong emphasis on safety, infection control, patient dignity, and effective communication throughout.
Most written questions follow a predictable format:
- A brief clinical scenario (patient’s condition, setting, situation)
- A specific question about the appropriate action
- Four answer choices, with one clearly best option
The questions test your ability to prioritize, recognize warning signs, and respond appropriately to patient needs. Research shows that scenario-based questions better predict real-world performance than factual recall questions alone.
Scenario-Based vs. Knowledge-Based Questions
About 60-70% of written questions are scenario-based, while the remainder test direct knowledge. For example:
- Scenario-based: “You enter Mr. Johnson’s room and find him slumped in his chair, unresponsive. What should you do FIRST?”
- Knowledge-based: “What is the normal range for adult blood pressure?”
Understanding this distinction helps you prepare effectively. Study both the facts AND how to apply them in clinical situations.
Pro Tip: When reading scenario questions, identify the core safety issue before looking at answer choices. This helps you eliminate inappropriate interventions quickly.
Key Content Domains for the Written Exam
The CNA written exam typically covers three main content areas. Here’s how they’re usually weighted:
| Content Domain | Percentage | Key Topics Covered |
|---|---|---|
| Basic Nursing Skills | 40-50% | Vital signs, infection control, positioning, nutrition, elimination |
| Psychosocial Care Skills | 20-30% | Communication, emotional support, cultural competence, dementia care |
| Role of the Nurse Aide | 10-20% | Legal/ethical issues, teamwork, scope of practice, delegation |
Winner/Best For: This structure ensures you’re tested on the most essential competencies for safe patient care, with Basic Nursing Skills receiving the most emphasis since they form your daily responsibilities.
Critical Thinking in Basic Nursing Skills
Basic Nursing Skills questions often test your judgment, not just your knowledge. Imagine this scenario: “Your patient has just returned from surgery with a new abdominal incision. When you take vital signs, you notice their respiratory rate is 28 breaths per minute. What should you do?”
The correct answer isn’t to recheck the vital sign in 15 minutes or document and continue your routine. It’s to report the elevated respiratory rate to your nurse immediately—this could indicate pain, bleeding, or respiratory compromise.
Sample Written CNA Test Questions (With Explanations)
Let’s break down some representative questions to show you exactly how to think through them:
Question 1: While assisting Mrs. Smith with feeding, she begins to choke. Her airway is partially obstructed and she can cough forcefully. What should you do FIRST?
- A) Perform the Heimlich maneuver immediately
- B) Encourage her to keep coughing
- C) Leave to get the nurse
- D) Give her a drink of water
Correct Answer: B) Encourage her to keep coughing Explanation: When a patient can cough forcefully or speak, their airway is only partially obstructed. The cough is the most effective clearing mechanism. The Heimlich (A) is reserved for complete airway obstruction. Getting the nurse (C) delays immediate care. Water (D) could worsen the obstruction.
Question 2: You need to transfer a weak patient from bed to wheelchair using a gait belt. Which position should the wheelchair be in?
- A) Parallel to the bed, locked brakes, footrests up
- B) At a 45-degree angle, locked brakes, footrests moved out
- C) Directly facing the bed, brakes unlocked
- D) Anywhere convenient as long as brakes are locked
Correct Answer: B) At a 45-degree angle, locked brakes, footrests moved out Explanation: The 45-degree angle allows for a natural pivot transfer without awkward twisting. Locked brakes ensure safety. Moving footrests prevents tripping hazards. Positioning parallel (A) requires the patient to turn too far. Facing the bed (C) makes transfer awkward.
Question 3: A resident with severe dementia repeatedly calls out “Help me! Help me!” but appears calm. What is your BEST initial response?
- A) Ignore the calls as attention-seeking behavior
- B) Tell them firmly that nothing is wrong
- C) Approach calmly and ask, “How can I help you?”
- D) Call their family to report the behavior
Correct Answer: C) Approach calmly and ask, “How can I help you?” Explanation: Even when speech seems repetitive or doesn’t make logical sense, always validate the person’s feelings and attempt to respond to the underlying need. Ignoring (A) or being dismissive (B) increases agitation. Family (D) may need updates, but isn’t the immediate response.
Key Takeaway: Every correct CNA answer prioritizes safety, dignity, and effective communication above all else.
What to Expect on the CNA Clinical Skills Test
The skills portion evaluates your ability to perform essential nursing assistant tasks correctly. You’ll enter a simulated clinical setting with a manikin or another student acting as your patient. An evaluator will observe you performing randomly selected skills and mark each step on a criticality checklist.
The evaluator can only say “pass” or “fail” for each step—no hints or guidance during the test. Some steps are “critical,” meaning missing even one results in automatic failure of that task. However, you usually can miss up to 2-3 non-critical steps and still pass.
The Criticality Checklist System
Every skill has a precise checklist with essential steps. For Hand Hygiene, critical steps typically include:
- Wetting hands first before applying soap
- Using friction for 15-20 seconds
- Cleaning all surfaces (palms, backs, between fingers)
- Rinsing thoroughly
- Using paper towel to turn off faucet
Missing any critical step means failing that skill, regardless of how well you performed others. That’s why practice becomes automatic is essential.
Pro Tip: Always narrate your steps during the skills test. “I’m washing my hands now,” helps you remember the sequence and demonstrates your understanding of infection control principles.
Top Tested Skills on the CNA Exam (And How They’re Graded)
While skills vary by state, some appear consistently across examinations. Master these and you’ll be prepared for whatever combination appears on your test day.
1. Hand Hygiene
This skill appears in nearly every exam, either as a standalone skill or as the first/last step of other skills like perineal care or dressing changes.
Critical elements:
- Proper technique duration (15-20 seconds)
- All surfaces cleaned
- Avoiding recontamination
- Proper drying
2. Bed to Wheelchair Transfer
This fundamental skill tests safety, body mechanics, and patient communication.
Critical elements:
- Locking wheelchair brakes
- Using gait belt correctly
- Proper body mechanics (bend knees, not back)
- Communication throughout transfer
- Final positioning (patient comfortable, aligned)
3. Vital Signs (Blood Pressure)
This skill requires both technical competence and proper patient interaction.
Critical elements:
- Correct cuff size selection
- Proper positioning of arm
- Correct stethoscope placement
- Accurate reading to nearest 2 mmHg
- Recording findings properly
Common Critical Steps Across All Skills:
- Introducing yourself to the patient
- Explaining the procedure
- Providing privacy (closing curtain/door)
- Handwashing before and after
- Calling the patient by preferred name
- Ensuring patient safety and comfort throughout
Common Mistakes CNA Students Make on Exam Day
Let’s be honest—exam nerves can lead to silly mistakes you’d never make during clinical practice. Awareness helps you avoid them.
Written Exam Pitfalls:
- Overthinking simple questions
- Missing keywords like “first,” “best,” or “most important”
- Choosing the most comprehensive answer instead of the most immediate/prioritized one
- Changing correct answers due to self-doubt
Skills Test Mistakes:
- Forgetting hand hygiene before or after skills
- Neglecting indirect care steps (introduction, privacy, communication)
- Rushing through steps without ensuring quality
- Improper use of equipment (e.g., wrong blood pressure cuff size)
Common Mistake: Many students pass the technical steps but fail the “indirect care” portion of skills evaluation. Remember: how you communicate and treat the patient matters as much as the technical skill itself.

FAQ Section
Q: What happens if I pass the written portion but fail the skills test? A: You typically need to retake only the portion you failed within a specific timeframe (usually 2 years), though some states require both parts. Check your specific state’s requirements, most allow you to retest only the failed portion.
Q: How many questions can I miss and still pass the written exam? A: Most states require passing at least 75-80% of questions. On a 70-question test, this means missing 17 or fewer questions. However, the exact passing score varies by state, so confirm your local requirements.
Q: What if I forget a step during the skills evaluation? Can I go back? A: Generally no. The evaluator marks steps as they occur. However, if you realize your mistake immediately, you might say, “I forgot to wash my hands first—may I do that now?” Some evaluators allow this if caught instantly, but don’t count on it.
Q: Is the skills test done on real patients or manikins? A: Most programs use fellow students or manikins for skills testing. Very few programs use actual residents. The testing environment is simulated but designed to feel realistic. Focus on proper technique regardless of who or what your “patient” is.
