Certified Nursing Assistant interview questions and sample answers
A certified nursing assistant interview usually mixes two kinds of question: ones that test whether you know the job, and behavioral ones that ask for proof from your past. Below are 10 of the first with a short model answer, and 5 of the second with what the interviewer is really checking. Rewrite every answer in your own words and with your own numbers.
Job-specific questions
1. How do you assist a resident with limited mobility to transfer from bed to wheelchair safely?
I use a gait belt, position the wheelchair at the correct angle, lock the brakes, and use proper body mechanics, bending my knees not my back, to guide rather than lift the full weight. If the resident needs a mechanical lift per their care plan, I use that instead of attempting a manual transfer alone.
2. What do you do if you notice a change in a resident's condition, like confusion that wasn't there before?
I document what I observed specifically, like time of onset and symptoms, and report it to the nurse right away rather than waiting until end of shift. Sudden confusion can signal something serious like a UTI or stroke, so timely reporting matters.
3. How do you handle a resident who refuses to eat or take a shower?
I don't force it, I try to understand why, maybe they're in pain or just want to wait, and offer it again a bit later or suggest an alternative like a different meal option. I document the refusal and inform the nurse, since repeated refusals might need a care plan adjustment.
4. Walk me through proper technique for repositioning a bedbound patient to prevent pressure sores.
I reposition at least every two hours following the care plan schedule, using pillows to support pressure points like heels and hips, and I check skin condition each time for early redness. Catching a stage one pressure injury early prevents it from becoming a much worse wound.
5. How do you take and document vital signs accurately for multiple residents on your assignment?
I follow the same routine for each resident, blood pressure, pulse, temperature, and respiration, and document immediately at bedside rather than trying to remember numbers for several residents later. I flag anything outside normal range to the nurse right away instead of just charting it and moving on.
6. What would you do if a resident became verbally or physically aggressive during care?
I stay calm, step back to a safe distance if needed, and try to de-escalate rather than push through the care task, since forcing it usually makes things worse. I inform the nurse so we can adjust the approach, maybe trying again later or with a different technique.
7. How do you maintain dignity and privacy while assisting with toileting or bathing?
I close the door or curtain, explain what I'm doing before I do it, and keep the resident covered as much as possible throughout the task. Treating these tasks matter-of-factly rather than awkwardly helps the resident feel less embarrassed.
8. Describe how you handle infection control when caring for multiple residents in a shift.
I wash hands or use hand sanitizer before and after every resident contact, use gloves for any contact with bodily fluids, and follow any specific isolation precautions noted on the door or chart. Cross-contamination between residents is one of the most preventable risks in a facility.
9. How do you communicate observations to the nursing staff at shift change?
I give a clear, specific handoff on each resident I was assigned, mentioning anything abnormal like reduced intake or a new skin issue, not just 'everything was fine.' Specific details help the next shift catch a trend that a vague report would miss.
10. What do you do if you're assigned more residents than you feel you can safely care for in a shift?
I raise it with the charge nurse right away rather than just trying to rush through and risk missing something like a fall check or medication reminder. Patient safety and my own ability to actually catch problems matters more than not wanting to seem like I can't handle the assignment.
Behavioral questions

A result to build the answer around: Cared for 12 residents per shift with bathing, feeding, dressing and mobility.
12. Describe a time you improved how something was done.
What they are checking: That you notice waste and fix it without being told, then measure the difference.

A result to build the answer around: Spotted early signs of infection in 3 residents, getting them treated same day.
15. What is something you learned from a mistake?
What they are checking: Ownership without excuses, and the habit you changed so it did not happen again.
