ICU Nurse Job Description: Duties, Template & Pay (2026)
An ICU nurse, also called a critical care nurse, is a registered nurse who cares for patients whose conditions can change minute to minute: people on ventilators, titrated drips and invasive lines after major surgery, trauma, sepsis or cardiac events. The role needs an RN license; units usually hire for acute care experience, and some run new-graduate residencies. This page has an ICU nurse job description template, the licensing and certification rules quoted at source, interview questions and pay.
What an ICU nurse does
BLS describes critical care nurses as nurses who “work in intensive-care units in hospitals, providing care to patients with serious, complex, and acute illnesses and injuries that need close monitoring and treatment.” O*NET profiles the role separately as Critical Care Nurses (29-1141.03): “Provide specialized nursing care for patients in critical or coronary care units.” Job titles O*NET reports for it include ICU Nurse, Intensive Care Unit Registered Nurse (ICU RN), Critical Care Registered Nurse (CCRN) and Newborn ICU RN.
BLS does not publish separate pay or employment figures for ICU nurses. They are counted with registered nurses (SOC 29-1141), and all pay and employment figures on this page describe that group.
ICU nurse duties
The list below follows the tasks O*NET lists for critical care nurses.
- Evaluate vital signs and laboratory data to determine the need for emergency intervention
- Monitor patients for changes in status and signs of conditions such as sepsis or shock, and start appropriate interventions
- Give medications intravenously, by injection, orally, through gastric tubes or by other methods
- Monitor fluid intake and output to catch fluid and electrolyte imbalances early
- Prioritize care for assigned critically ill patients based on assessment data
- Set up and monitor equipment such as cardiac monitors, mechanical ventilators and alarms, oxygen delivery devices, transducers and pressure lines
- Conduct pulmonary assessments and assess pain and sedation needs
- Give blood and blood products and watch for transfusion reactions
- Assist physicians with procedures such as bronchoscopy, endoscopy, endotracheal intubation and elective cardioversion
- Collaborate with the care team on treatment plans, and support patients' families
- Document assessments, interventions and outcomes
Licensing and certification
BLS: “Registered nurses must have a nursing license issued by the state in which they work. To become licensed, nurses must graduate from an approved nursing program and pass a qualifying exam.” A nurse may also practice on a multistate license where your state is part of the Nurse Licensure Compact; see compact nursing states. BLS adds that positions may require CPR, BLS or ACLS certification, and specialty certifications are usually voluntary.
For hospitals in Medicare, 42 CFR 482.23(b) requires “adequate numbers of licensed registered nurses, licensed practical (vocational) nurses, and other personnel to provide nursing care to all patients as needed,” a procedure to ensure nursing personnel have “valid and current licensure,” and that a registered nurse assign each patient's care “in accordance with the patient's needs and the specialized qualifications and competence of the nursing staff available.” The federal rule does not set an ICU nurse-to-patient ratio; some states set their own staffing rules, so check yours. This is general information, not legal advice.
CCRN certification
The main specialty credential is CCRN from the American Association of Critical-Care Nurses (AACN), with adult, pediatric and neonatal versions. For CCRN (Adult), AACN requires “a current, unencumbered U.S. RN or APRN license” and either:
- “1,750 hours in direct care of acutely/critically ill adult patients during the previous two years, with 875 of those hours accrued in the most recent year preceding application,” or
- “a minimum of 2,000 hours in direct care of acutely/critically ill adult patients” during the previous five years, “with 144 of those hours accrued in the most recent year preceding application.”

Requirements: what to ask for, and what to drop
| Requirement | What to know |
|---|---|
| RN license | Keep it. Every state requires it. Accept compact licenses where your state is in the compact. |
| Prior ICU experience | Consider replacing with “acute care experience” and a structured orientation. Step-down, telemetry and emergency nurses already manage monitors and unstable patients. |
| CCRN at hire | Drop it as a requirement; list it as a plus. Eligibility depends on hours caring for acutely or critically ill patients. |
| ACLS | Keep it, but allow a window after hire if you run classes in-house. |
| BSN | Follow your hospital policy. If you accept ADN with a timeline to a BSN, say so; many experienced nurses stop reading at “BSN required.” |
| Schedule | Be exact: 12-hour shifts, nights, weekend and holiday rotation. BLS notes that hospital nurses usually work shifts to provide round-the-clock coverage. |
ICU nurse job description by unit
Medical ICU (MICU)
Sepsis, respiratory failure, multi-organ failure. Mention ventilator and CRRT volume and whether the unit runs a proning protocol.
Surgical and trauma ICU (SICU)
Post-operative and trauma patients, often with drains, chest tubes and frequent returns to the OR. Say whether you are a trauma center and at what level.
Cardiovascular ICU (CVICU) and coronary care
Open-heart recoveries, balloon pumps, pacing wires and titrated vasoactive drips. Name the devices the nurse will manage.
Neonatal ICU (NICU) and pediatric ICU (PICU) nurse
Different patient populations with their own competencies and CCRN versions (pediatric and neonatal). Write a separate description; do not adapt the adult one. NRP or PALS belongs in the requirements.
New graduate ICU nurse residency
Lead with the length of the residency, the preceptor model and the classroom component. Requirements shrink to the license (or the NCLEX date) and BLS; ACLS is taught during orientation.
What ICU nurses earn
BLS does not publish an ICU nurse wage. Registered nurses had a median of $97,550 a year, or $46.90 an hour, in May 2025; the lowest 10 percent earned less than $68,940 and the highest 10 percent more than $137,470. Because ICU nurses work in hospitals, the more useful reference is the BLS median for RNs in hospitals: $100,220. Check local postings for ICU-specific rates and differentials before you set a range.
BLS counted 3,465,400 RN jobs in 2025, 59 percent of them in hospitals, and projects employment to grow 6 percent from 2025 to 2035, faster than the average for all occupations, with about 180,800 openings a year.
Interview questions for an ICU nurse
1. Your ventilated patient's pressure drops and their heart rate climbs. Walk me through the next five minutes.
A good answer is structured: assess the patient, check lines and the ventilator, notify the provider, follow the protocol and call for help early. Candidates who jump straight to one intervention without assessing are a concern.
2. Which drips have you titrated, and how do you decide when to change the rate?
Listen for specific drugs, titration parameters in the order and awareness of what to watch. It tells you quickly whether the experience matches your unit.
3. Tell me about a time you recognized sepsis or deterioration before anyone else did.
Strong answers name the early signs they noticed and the escalation they made. This is the core judgment of the job.
4. How do you handle a family member who is angry about their relative's care?
ICU families are frightened. Look for listening, calm explanation within scope, and involving the provider or social work.
5. A physician gives you a verbal order during a code that you think is wrong. What do you do?
A good answer: say it out loud, confirm with closed-loop communication, and escalate if the concern remains. Silence is the wrong answer.
6. What would help you most in your first three months here?
Useful for new-to-ICU hires: realiztic nurses name preceptor time, drip references and a mentor. It also tells you what to put in the orientation plan.
What it costs to reach an ICU nurse
ICU nurses are registered nurses, so we use the registered nurse role family. In our 2026 Social Job Advertising Benchmark it ran a median cost per applicant of $19.08 on Meta, with the middle half of campaigns between $12.76 and $34.84, a blended figure of $20.00 and an 11 percent apply rate. The healthcare and senior living sector as a whole ran a $15.42 median at a 16 percent apply rate, and the all-role median is $13.88.
Apply rate explains 70 percent of the variation in cost per applicant across the benchmark. For ICU postings, a short form that asks for license state, unit experience and shift preference, followed by a same-day call from someone who can answer clinical questions, is what keeps it down. Cost per applicant is not cost per hire.

The job description is not the job ad
The template is the document for your files. The ad has to reach a step-down or ED nurse who is not looking for a job right now.
- Lead with the unit, the typical assignment and the schedule. Many ICU nurses judge a unit by its assignment before its pay.
- Say what the orientation is: length, preceptor, classes. That is what moves a nurse who is new to critical care.
- Show the pay range and differentials.
- Keep the application short and call back the same day. Licensed nurses have options and do not wait.
- On Facebook and Instagram, job ads run under Meta's employment special ad category: a location radius of at least 15 miles and no targeting by age, gender or ZIP code. Let the copy name the unit and the qualifications.

Frequently asked questions
What does an ICU nurse do?
An ICU nurse is a registered nurse who cares for critically ill patients in an intensive care unit. The work includes evaluating vital signs and lab data, watching for sepsis or shock, giving IV medications and blood products, managing ventilators and monitoring lines, assisting with procedures such as intubation, supporting families and documenting every assessment and intervention.
What should an ICU nurse job description include?
Include the unit type, bed count, typical patient assignment, schedule and differentials, the RN license requirement, the experience you actually need, required cards such as BLS and ACLS, the orientation length and preceptor model, CCRN as a plus, the pay range and how quickly a recruiter will call. Name the devices and drips nurses will manage.
What qualifications does an ICU nurse need?
An ICU nurse needs an RN license valid in your state, which requires graduating from an approved nursing program and passing the licensing exam. Hospitals commonly also require BLS and ACLS and some acute care experience, although some run new-graduate ICU residencies. CCRN certification is a common plus but requires critical care clinical hours first.
Should I require CCRN certification for ICU nurses?
Usually not at hire. AACN requires 1,750 hours of direct care of acutely or critically ill adult patients in the previous two years, or 2,000 hours over five years, to sit for CCRN (Adult). Requiring it excludes new graduates and many nurses new to critical care. List it as a plus and pay for the exam once eligible.
How much do ICU nurses make?
BLS does not publish an ICU-specific wage. Registered nurses had a median of $97,550 a year, or $46.90 an hour, in May 2025, and RNs working in hospitals had a median of $100,220. Check local ICU postings for differentials before setting a range, because night, weekend and certification pay vary by hospital.
Is there a required nurse-to-patient ratio in the ICU?
Not under federal rules. The Medicare hospital conditions at 42 CFR 482.23 require adequate numbers of licensed nurses and that an RN assigns care based on patient needs and staff competence, but set no ICU ratio. Some states set their own staffing rules, so check your state's requirements. This is general information, not legal advice.
Can a new graduate nurse work in the ICU?
Yes, in hospitals that run a structured ICU residency or extended orientation. The posting should lead with the residency length, preceptor model and classes, and keep requirements to the RN license or a scheduled NCLEX date plus BLS. ACLS is often taught during orientation. Say so plainly, because many new graduates assume ICU roles are closed to them.
What interview questions should I ask an ICU nurse?
Ask them to walk through a deteriorating ventilated patient, which drips they have titrated and how, a time they caught sepsis early, how they handle an angry family member, what they do when an order during a code seems wrong, and what support they would need in their first three months. Look for structured assessment and early escalation.
What is the difference between an ICU nurse and a critical care nurse?
In practice they are the same job. O*NET profiles it as critical care nurses and lists ICU Nurse and Intensive Care Unit Registered Nurse among reported job titles. Critical care is the broader term and also covers coronary care, cardiovascular, neonatal and pediatric intensive care units, each with its own competencies.
How much does it cost to recruit an ICU nurse?
On Meta, the registered nurse role family in Boostpoint's 2026 benchmark ran a median of $19.08 per applicant, with the middle half of campaigns between $12.76 and $34.84 and an 11 percent apply rate. That is cost per applicant, not cost per hire. A short form and a same-day call keep it at the low end.
