ICU nurse interview questions: 22 questions and a scorecard for interviewers
The short answer
Good ICU nurse interview questions test how a critical care nurse manages ventilated patients and vasoactive drips, reads hemodynamic data, spots sepsis and deterioration early, performs in codes, and supports families through critical illness and end-of-life decisions. Ask for real patients, such as a blood pressure that kept falling on vasopressors or a family meeting about withdrawing treatment, and listen for what they checked, what they did and who they called. Before the interview, verify the RN license on Nursys in the US or the NMC register in the UK, and confirm CCRN, BLS and ACLS with the issuers if the client asks for them. Score every candidate against the same five criteria so the decision rests on evidence.

When to use these questions
ICU nurses care for a small number of the sickest patients in the hospital, so small changes matter and decisions are made in minutes: titrating vasopressors and sedation, managing ventilators and invasive lines, recognizing sepsis or bleeding, and starting resuscitation. They also spend long hours with frightened families, often through decisions about withdrawing treatment. A general nursing interview misses most of this, so ask about specific critically ill patients and listen for the numbers they watched, the checks they made and when they escalated.
For travel and agency ICU assignments, confirm the must-haves before the clinical interview: an active RN license for the state of the assignment, or a multistate license under the Nurse Licensure Compact if both states are members; recent experience in the same type of ICU, such as medical, surgical, cardiac, neuro or trauma; the certifications the client asks for, commonly BLS and ACLS and sometimes AACN’s CCRN; and whether the candidate accepts floating, the shift pattern and the start date.
22 ICU nurse interview questions
Grouped by what they test. Pick the questions that match the role, ask every candidate the same ones in the same order, and score each answer against the scorecard below.
Ventilators, hemodynamics and titrated drips
Start with the equipment and medicines that make ICU nursing different. Strong candidates describe a routine they follow every time, then explain what they do when the numbers and the patient disagree.
Question 1: Walk me through how you assess a ventilated patient at the start of a shift, from the ventilator settings to the patient.
- Why ask it:
- Tests a systematic approach to the highest-risk equipment on the unit.
- A strong answer shows:
- Checking settings and alarms against orders, tube position and security, breath sounds, secretions, sedation level and recent blood gases, and what they do when something doesn’t match.
- Follow-up:
- What would make you call respiratory therapy or the provider straight away?
Question 2: Tell me about a patient on vasopressors whose blood pressure kept dropping as you titrated up. What did you check, and who did you involve?
- Why ask it:
- Safe titration within ordered parameters is a core ICU skill.
- A strong answer shows:
- Staying within the ordered range, checking the line, pump and transducer, looking for a cause such as bleeding or sepsis, and calling the provider well before reaching the maximum dose.
Question 3: How do you make sure an arterial line or central venous reading is accurate before you act on it?
- Why ask it:
- Acting on a damped waveform or a badly leveled transducer can lead to the wrong treatment.
- A strong answer shows:
- Leveling and zeroing, checking the waveform, comparing with a cuff pressure and the patient’s condition, and not treating a number that doesn’t fit the clinical picture.
Question 4: Which continuous infusions are you comfortable titrating under protocol, and which would you want a second check on in an unfamiliar hospital?
- Why ask it:
- Matches the nurse’s drip experience to the client’s patients and policies.
- A strong answer shows:
- Specific medications, such as sedatives, vasopressors, insulin or heparin, awareness that titration protocols differ between hospitals, and honest limits.
Question 5: How do you manage sedation, pain and delirium for a patient on a ventilator?
- Why ask it:
- Too much or too little sedation affects safety, weaning and recovery.
- A strong answer shows:
- Using the unit’s sedation, pain and delirium scales, daily sedation interruptions and breathing trials where ordered, non-drug measures, and agreeing targets with the team.
Deterioration, sepsis and codes
ICU nurses are expected to see trouble coming. Listen for early signs, fast escalation and a clear role when a patient arrests.
Question 6: Tell me about a time you recognized sepsis early. What were the first signs, and what happened in the first hour?
- Why ask it:
- Early recognition and quick action change the course of sepsis.
- A strong answer shows:
- Specific early signs, such as a change in mental status, heart rate, breathing or lactate, prompt escalation, and following the sepsis protocol for cultures, fluids and antibiotics as ordered.
- Follow-up:
- What exactly did you tell the provider when you called?
Question 7: Walk me through your role in the last code you took part in. What went well, and what would you change?
- Why ask it:
- Tests performance during resuscitation and honest reflection afterwards.
- A strong answer shows:
- A clear role, such as compressions, medications, recording or airway support, closed-loop communication, and a specific lesson from the debrief.
Question 8: An hour after arriving from the operating room, your patient becomes hypotensive and tachycardic. Talk me through your first ten minutes.
- Why ask it:
- Tests structured assessment and escalation under time pressure.
- A strong answer shows:
- A rapid airway, breathing and circulation check, looking at drains and dressings for bleeding, reviewing trends, calling the surgical team early with a structured report, and preparing for likely orders.
Question 9: Tell me about a rapid response you attended or called. How did you decide whether the patient needed ICU care?
- Why ask it:
- Tests judgment about escalating the level of care and working with ward staff in an emergency.
- A strong answer shows:
- A focused assessment, clear communication with the ward nurse and provider, and a sound reason for transferring the patient or keeping them on the ward with a plan.
Question 10: Tell me about a near miss with a high-alert infusion or an infusion pump. What happened afterwards?
- Why ask it:
- ICU patients receive many high-alert infusions at once, so safe habits and honest reporting matter.
- A strong answer shows:
- Independent double checks, using the pump’s drug library, tracing each line to its source, prompt reporting and a change in their own practice.
Families, ethics and end-of-life care
Critical illness puts families under great strain. Look for honesty, compassion and knowing when to bring in the provider, palliative care or ethics.
Question 11: How do you prepare a family who are about to see their relative on a ventilator for the first time?
- Why ask it:
- The ICU nurse shapes how frightened and overwhelmed families cope.
- A strong answer shows:
- Preparing them before they enter, explaining the equipment in plain language, inviting questions, and arranging for the provider to answer questions about prognosis.
Question 12: Tell me about a family who wanted everything done when the team believed treatment was no longer helping. What was your role?
- Why ask it:
- Tests communication and advocacy in goals-of-care conflicts.
- A strong answer shows:
- Listening to the family, making sure a family meeting happened, speaking up for the patient’s known wishes, and involving palliative care, ethics or chaplaincy as the hospital allows.
Question 13: Walk me through how you care for a patient and their family during withdrawal of life-sustaining treatment.
- Why ask it:
- End-of-life care in the ICU needs clinical skill as well as compassion.
- A strong answer shows:
- Following the orders and the unit’s comfort care protocol, managing symptoms, preparing the family for what they will see, privacy, and support after the death.
Question 14: What do you do when a patient’s advance directive or code status seems to conflict with what the family is asking for?
- Why ask it:
- Tests whether the nurse escalates ethical and legal questions instead of acting alone.
- A strong answer shows:
- Checking the documentation, telling the provider promptly, involving ethics or risk management under hospital policy, and keeping the patient’s own wishes central.
Acuity, handover and new units
ICU workloads change by the minute, and travel nurses must work safely in units they have never seen. Look for clear priorities and a habit of asking for help early.
Question 15: Both of your patients need you urgently at the same moment. How do you decide where to go, and how do you get help?
- Why ask it:
- Safe triage between two unstable patients is a daily ICU skill.
- A strong answer shows:
- Dealing with the most immediate threat to life first, calling the charge nurse or a colleague to cover the other patient, and speaking up rather than quietly stretching.
Question 16: Walk me through a bedside handover for a patient on a ventilator and several titrated drips.
- Why ask it:
- A missed detail at ICU handover can cause harm within minutes.
- A strong answer shows:
- Checking pumps, lines and ventilator settings together at the bedside, a structured format, current titration targets, pending results and the nurse’s main worries.
Question 17: Tell me about a time you were floated to a unit outside your specialty, such as step-down or a different type of ICU. How did you keep your patients safe?
- Why ask it:
- Agency and travel ICU nurses are often floated, so knowing their limits matters.
- A strong answer shows:
- Asking about the patient population and protocols, declining tasks outside their competence, and finding a resource nurse at the start of the shift.
Question 18: On a new travel ICU contract, what do you check before you take your first full assignment?
- Why ask it:
- Tests a structured approach to orientation in an unfamiliar hospital.
- A strong answer shows:
- The code cart and emergency equipment, titration protocols and the pump library, how to escalate and to whom, and the unit’s documentation and alarm practices.
Must-haves and logistics
Ask these of every candidate before the clinical interview, and verify the answers.
Question 19: Which RN licenses do you hold, in which states, and is one of them a multistate compact license that covers the state of this assignment? (In the UK: please share your NMC PIN.)
- Why ask it:
- The Nurse Licensure Compact covers RN and LPN/VN licenses, and a multistate license issued by the home state allows practice in all compact states.
- A strong answer shows:
- License numbers and states that you then check on Nursys, or on the NMC register in the UK, before submitting the candidate.
Question 20: Are your BLS and ACLS current, do you hold CCRN or another critical care certification, and when does each one expire?
- Why ask it:
- ICU clients commonly ask for BLS and ACLS, and CCRN eligibility requires recent direct-care hours with acutely or critically ill patients.
- A strong answer shows:
- Exact certifications and expiry dates that you then confirm with AACN and the issuing training center.
Question 21: Which types of ICU have you worked in during the last two years, such as medical, surgical, cardiac, neuro or trauma, and what was your usual patient assignment?
- Why ask it:
- Clients want recent experience with the same patients and acuity as the assignment.
- A strong answer shows:
- Specific units and hospitals, their usual one- or two-patient assignments, and the drips and devices they handled routinely.
- Follow-up:
- Have you managed continuous renal replacement therapy, an intra-aortic balloon pump or other advanced devices?
Question 22: This contract is [type of ICU, shift length, nights or weekends, floating expectations, location and number of weeks] and involves [tasks such as turning and repositioning patients, CPR and moving equipment]. Can you do these tasks, with or without adjustments, and what is your earliest start date?
- Why ask it:
- Surfaces schedule, floating and task mismatches before the candidate is submitted.
- A strong answer shows:
- A clear yes, or the specific limit, and a firm start date.

Red flags, and questions not to ask
- Vague about which ICU they worked in, the drips they titrated or the devices they managed, or presenting step-down work as ICU experience.
- Titrating infusions outside ordered parameters, or acting on a monitor reading without checking the line, transducer or patient.
- No example of escalating early, or describing escalation as the charge nurse’s job alone.
- Dismissive about families, or visibly uncomfortable discussing end-of-life care.
- License or certification details that don’t match Nursys, AACN or the NMC register, or reluctance to share them.
- Age, marital or family status, pregnancy or plans for children, religion, ethnicity or national origin, sexual orientation or gender identity. These are protected characteristics under the UK Equality Act 2010 and US federal law, and they say nothing about whether someone can do the job.
- Health, sickness absence or disability before an offer. You can ask whether the candidate needs any adjustments for the interview, and whether they can do the essential tasks of the job.

ICU nurse interview questions: frequently asked questions
Still deciding?
Bring a live vacancy and we’ll walk through where automation ends and recruiter review begins.
Ask for real critically ill patients that test ventilator and hemodynamic skills, titration of drips, early recognition of sepsis and deterioration, performance in codes, family communication and end-of-life care, and safe practice on new units. Add must-have questions about the RN license, BLS, ACLS and any CCRN certification, ICU type and availability, and ask every candidate the same questions in the same order.
In the US, use Nursys, NCSBN’s national database for verifying the licensure and discipline of RNs, LPN/VNs and APRNs in participating jurisdictions; its Licensure QuickConfirm service is free for employers and recruiters. AACN offers free online verification of all its certifications, including CCRN, which it says may be used as primary source verification. If BLS or ACLS cards come from the American Heart Association, check the eCard code at heart.org/cpr/mycards. In the UK, search the NMC register using the nurse’s PIN.
Check what the client asks for: CCRN is a specialty certification from AACN, separate from the RN license, offered in adult, pediatric and neonatal versions. Its direct care route requires a current, unencumbered US RN or APRN license and either 1,750 hours of direct care of acutely or critically ill patients in the previous two years, with 875 in the most recent year, or at least 2,000 hours in the previous five years, with 144 in the most recent year. Ask when the candidate certified and when the certification is due for renewal, then confirm it with AACN.
The core questions on safety, communication and teamwork still apply, but an ICU interview goes deeper into ventilators, invasive monitoring, titrated infusions, sepsis, codes and end-of-life decisions, and asks which type of ICU the nurse has worked in recently. For travel and agency nurses, add questions on floating and on getting up to speed with a new hospital’s protocols and equipment.
