CNA Interview Questions
18 CNA interview questions on patient care, infection control, residents' rights and reporting changes, with what good answers include. For both sides.
What's here
18 CNA interview questions, grouped into 4 areas: motivation and patient care, clinical skills and safety, observation, reporting and teamwork and ethics and situational questions. Each one comes with why it is worth asking and what a strong answer contains, so the same question can be scored the same way by different interviewers.
- Confirm certification and state registry status as part of screening, before the interview, so the conversation can focus on care.
- Ask candidates to talk through a transfer or vital signs step by step; vague answers suggest weak habits.
- Score the abuse reporting scenario heavily. Loyalty to colleagues should never outweigh resident safety.

Preparing for this interview yourself? Practise it free →A certified nursing assistant (CNA) gives hands-on care to patients and residents in nursing homes, hospitals and home care: bathing, dressing, toileting, feeding, moving and turning people, checking vital signs and reporting changes to the nurse. CNAs work under the supervision of licensed nurses, and in the US they generally pass a state competency exam and are listed on a state registry. These questions test compassion, safety habits and the judgement to report problems quickly. Interviewers can use the 'what to look for' notes as a scoring guide; candidates can use them to prepare.
Motivation and Patient Care
Why the candidate chose care work and how they treat the people they look after.
- 1
Why did you become a CNA?
Why ask it
Care work is physically and emotionally demanding. Genuine motivation predicts staying power.What to look for
A personal reason connected to helping people, often from caring for a relative or a positive experience of care. Awareness that the work is hard and a sense of pride in it. - 2
How do you protect a resident's dignity and privacy during personal care?
Why ask it
Dignity in personal care is at the heart of residents' rights.What to look for
Knocking and introducing themselves, explaining what they will do, closing doors and curtains, keeping the person covered, encouraging them to do what they can, and asking about preferences. - 3
Tell me about a patient or resident you found difficult to care for. How did you handle it?
Why ask it
Shows patience and professional behaviour under stress.What to look for
Trying to understand the cause (pain, fear, confusion), staying calm, adjusting their approach, involving the nurse, and not taking it personally. No blaming or mocking the patient. - 4
How do you care for a resident with dementia who refuses help with bathing?
Why ask it
Caring for cognitively impaired residents is a core part of CNA training.What to look for
Not forcing care, trying again later or with a different approach, simple calm language, offering choices, using familiar routines, and reporting persistent refusal to the nurse.

Whether the candidate has safe, practised habits for the tasks a CNA does every shift.
- 5
Walk me through how you take a resident's vital signs and what you do with the results.
Why ask it
Accurate vital signs and prompt reporting are basic CNA duties.What to look for
Hand hygiene, identifying the resident, explaining, correct technique, recording promptly in the facility's system, and telling the nurse straight away about readings outside the resident's normal range or the facility's parameters. - 6
How do you safely transfer a resident from bed to wheelchair?
Why ask it
Transfers carry injury risk for residents and staff.What to look for
Checking the care plan for the transfer method, locking brakes, using a gait belt or mechanical lift as required, asking for help when needed, good body mechanics, and telling the resident what is happening. Never skipping a two-person or lift requirement to save time. - 7
What infection control steps do you follow during a shift?
Why ask it
Infection control is one of the first areas covered in nurse aide training.What to look for
Hand hygiene before and after contact, correct use of gloves and other personal protective equipment, following isolation precautions, handling linen and waste correctly, and cleaning equipment between residents. - 8
How do you help prevent pressure injuries?
Why ask it

What would you do if a resident fell while you were in the room?
Why ask it
Tests safety response and following procedure.What to look for
Not moving the resident, calling for the nurse, staying with them and reassuring them, and helping with the incident report afterwards. Candidates who would lift the resident straight back up are a concern.
Observation, Reporting and Teamwork
CNAs spend more time with residents than anyone else, so what they notice and report matters.

What changes in a resident would you report to the nurse immediately?
Why ask it
Recognising and reporting abnormal changes is a defined CNA responsibility.What to look for
Sudden confusion, breathing difficulty, chest pain, a fall, a big change in vital signs, new pain, not eating or drinking, changes in skin or urine output. Strong answers say they report even when unsure. - 11
A resident asks you to give them their medication. What do you do?
Why ask it
Checks understanding of scope. Whether a nursing assistant may dispense medication depends on training level and state.What to look for
Knowing what their own certification and the facility allow, and passing the request to the nurse if medication is outside their role. Never guessing. - 12
How do you hand over at the end of your shift?
Why ask it
Missed information between shifts harms residents.What to look for
Completing documentation, telling the incoming aide and nurse about changes, concerns and anything left undone, and following the facility's handover routine. - 13
How do you prioritise when several residents need help at the same time?
Why ask it
Short staffing makes prioritisation a daily reality.What to look for
Safety first (someone at risk of falling or in distress), then time-critical needs such as toileting or meals, asking colleagues for help, and telling residents when they will be back. Communicating with the nurse if workload is unsafe.
Ethics and Situational Questions
Scenarios that test honesty, residents' rights and the courage to speak up.
- 14
You see a colleague speaking roughly to a resident and handling them harshly. What do you do?
Why ask it
Freedom from abuse and neglect is a core residents' right, and CNAs are often the first to see problems.What to look for

A resident's family member is angry that their mother has not been bathed today. How do you respond?
Why ask it
Families are a big part of the job, and tempers run high.What to look for
Listening without being defensive, apologising for the concern, explaining what they can, involving the nurse, and following up. Not blaming colleagues. - 16
You realise you forgot to record a resident's fluid intake earlier. What do you do?
Why ask it
Tests honesty about mistakes.What to look for
Recording it as soon as possible following the facility's late-entry procedure, telling the nurse if accuracy is in doubt, and never making up numbers. - 17
How do you look after yourself in such a physical and emotional job?
Why ask it
Burnout and injury drive turnover in care work.What to look for
Good lifting habits, using breaks, talking to colleagues or a supervisor after hard shifts, and healthy routines outside work. Honest awareness of the strain. - 18
How would you support a resident who is near the end of life, and their family?
Why ask it

Comfort care (mouth care, repositioning, keeping them clean and warm), being calm and respectful, respecting cultural and religious wishes, giving the family privacy, and reporting signs of pain or distress to the nurse.
Running the interview well
- 1Confirm certification and state registry status as part of screening, before the interview, so the conversation can focus on care.
- 2Ask candidates to talk through a transfer or vital signs step by step; vague answers suggest weak habits.
- 3Score the abuse reporting scenario heavily. Loyalty to colleagues should never outweigh resident safety.
- 4Listen for the words residents and patients use about care: dignity, choice and privacy should come up unprompted.
- 5Ask what they would report to the nurse and how quickly; under-reporting is a bigger risk than over-reporting.
- 6Be honest about the unit, ratios and shift patterns so candidates can judge fit, which helps retention.
- 7Value candidates who have cared for family members; that experience often transfers well.
- 8Include a nurse from the unit on the panel so clinical answers are judged by someone who works alongside CNAs.
Common questions
What questions are asked in a CNA interview?
Expect questions on why you chose care work, how you protect dignity during personal care, infection control, safe transfers, what changes you would report to the nurse, how you handle difficult residents or families, and what you would do if you saw abuse.
How do I answer 'Why do you want to be a CNA?'
Give a genuine reason, such as caring for a relative or wanting to help people directly, and show you understand the work is physically and emotionally demanding. End with what you enjoy about it, such as building relationships with residents.
What does a CNA do?
The US Bureau of Labor Statistics describes nursing assistants as giving basic care and helping patients with daily activities: bathing, dressing, toileting, turning and transferring patients, measuring vital signs, serving meals and reporting health concerns to nurses. They work under licensed practical or vocational nurses and registered nurses.
Do CNAs need to be certified and registered?
In the US, nursing assistants generally complete a state-approved training programme and pass a competency exam, and those who pass are placed on a state registry. They must be on the registry to work in a nursing home. Some states also require continuing education or a background check, so check your state's certifying agency.
Can a CNA give medication?
It depends on the state and the aide's training. The BLS notes that, depending on training level and state, nursing assistants may dispense medication. If you are unsure, say you would follow your certification's scope and your facility's policy and pass the request to the nurse.
What should I ask at the end of a CNA interview?
Ask about the orientation period, how many residents a CNA typically cares for on each shift, how the team hands over between shifts, and what support is available for continuing education.
