ICU RN Interview Questions (2026 Prep Guide)

ICU RN interviews in 2026 typically include a 30-minute behavioral interview with a nurse manager, a clinical-scenario interview with a charge nurse or educator, and (for some hospitals) a working interview or shadow shift. Expect 6-10 clinical-scenario questions covering drips, vents, code response, communication, and prioritization. Compensation: 2026 ICU RN medians $80-115K base + $8-25K sign-on + $10-22/hr critical-care differential. Cardiology comp 2026 · ICU career path.

Clinical-scenario questions

"Your patient is on Levophed at 0.15 mcg/kg/min, MAP 58, you just gave a 500cc bolus 20 minutes ago. What do you do?"

Strong answers: assess overall (trend MAP, mentation, urine output, lactate, capillary refill); titrate Levo up per protocol; second pressor (vasopressin first if not already on); call MD for evaluation, consider second bolus if appropriate; check Hgb for occult bleeding; reassess in 15 min. Demonstrate you don't just titrate without thinking about cause.

"Patient is on AC 18, TV 450, FiO2 50%, PEEP 10. ABG: 7.28 / 52 / 68 / 22. What's your interpretation and next step?"

Acute respiratory acidosis with hypoxemia. Increase RR (vent setting, after MD order); consider increasing PEEP if pulmonary; sedation level — is patient over-breathing or hypoventilating? Suction. Reassess ABG in 30 min. If patient is paralyzed, deeper sedation. Demonstrate you can interpret ABG and connect to ventilator settings.

"Your patient codes. Walk us through the first 5 minutes."

Pulse check — confirm pulseless. Call code (overhead "Code Blue Room X"); start CPR (30:2 if BLS, continuous if intubated); attach pads; analyze rhythm; defibrillate if shockable; access (IV/IO); epi q3-5min; secondary cause assessment (Hs and Ts). Document times. Switch compressors q2min. Confirm you can clearly articulate the algorithm + roles.

"You have 2 patients. One is on multiple drips, recently extubated, family is angry. The other is stable post-CABG, just transferred from PACU but not yet seen by the surgeon. What do you do first?"

Demonstrate prioritization: airway/circulation first. Quick safety check on both. Stable post-CABG transfer needs vital signs, drain output, IS, neurovascular check, pain. Recently extubated patient may be more acute (airway risk) — prioritize. Family conversation gets a quick acknowledgment + "I'll be back in 15 minutes when I've stabilized both patients." Don't try to do everything at once.

"Your patient on heparin drip has a sudden drop in Hgb from 11 to 8. What's the workup?"

Recheck Hgb. Assess vitals (tachycardia? hypotension?). Visual: GI bleed? Surgical site? Retroperitoneal? Confirm heparin order/dose. Send PTT, fibrinogen, platelets. Notify MD immediately — likely needs heparin held. Type and screen if not active. Demonstrate you don't just panic on a Hgb drop — you connect it to the heparin and act methodically.

"Patient becomes confused, restless, pulling at lines. What do you do?"

Differential: hypoxia (check sat, ABG); hypoglycemia (BG check); med side effect (recent benzo, opioid, anticholinergic); ICU delirium; UTI/sepsis; electrolyte (Na+); withdrawal (ETOH, benzo). Assess + treat the cause. Restraints last resort, with order. Don't reach for sedation as the first move.

Communication questions

"How do you escalate to the MD overnight?"

SBAR — Situation, Background, Assessment, Recommendation. Be concise. Prepared with current vitals, recent labs, what's already been tried. Have an ask. Don't just call to "let them know" — call with a question or recommendation.

"Tell me about a time you disagreed with a physician about a patient's care."

Pick a real story. Demonstrate professional disagreement (escalating with concrete data, advocating for the patient), not insubordination. Resolution + what you learned.

"How do you handle an angry family member?"

Active listening first — let them vent. Acknowledge their feelings without agreeing/disagreeing. Stick to facts on patient's clinical status. Loop in social work, chaplain, attending if needed. Document. Don't take it personally; family fear/grief shows up as anger.

Ratio + workflow questions

"What ratio are you used to?"

Standard ICU ratio is 1:1 or 1:2. Some hospitals stretch to 1:3 in intermediate care or stable patients. California has 1:2 ICU minimum by law (Title 22). Be specific.

"How do you handle a stretched ratio (3 patients, all complex)?"

Communication with charge — flag concerns. Prioritize per acuity. Cluster care. Use ancillary help (UAPs for ADLs, RT for vent stuff). Document concerns. Most importantly, when you can't safely manage the assignment, escalate clearly.

"What's your charge nurse experience?"

If applicable: how long, how often, how many beds, how staffed, decision-making for admissions/transfers, conflict resolution. If no charge experience yet but interested, frame as growth area.

Drip and equipment-specific questions

"Which vasopressors are you comfortable titrating? Sedation drips? Antiarrhythmics?"

List specifically. Common ICU drips: Levophed, vasopressin, epinephrine, dopamine, neo (vasopressors); propofol, fentanyl, midazolam, dexmedetomidine (sedation); amiodarone, esmolol, diltiazem, nitroglycerin, nicardipine, nipride (cardiac); insulin, heparin (med-surg basics); paralytics (cisatracurium, rocuronium); pressors for septic shock vs cardiogenic shock — know the difference.

"What's your CRRT experience?"

If you've run CRRT: which modality (CVVH, CVVHD, CVVHDF), prefilter vs postfilter replacement, citrate vs heparin anticoagulation, troubleshooting (clotting, low pressure alarms, blood leak). If no experience, frame as growth area + willingness to learn.

"Have you managed ECMO patients?"

VV vs VA — know the difference (VV for respiratory, VA for cardiac/respiratory). If no direct experience, frame growth area; many hospitals do specific ECMO training before assignment.

Compensation + benefits questions (you should ask)

"What's the base + critical-care differential + shift differential?"

2026 ICU RN medians: base $80-115K (varies by state); critical care diff $5-10/hr; night diff $5-8/hr; weekend diff $3-5/hr. Confirm RN-IV (or whatever your level) base.

"What's the sign-on bonus structure?"

2026 medians: $8-25K sign-on, 1-3 year commitment with pro-rata recapture. Confirm net-of-tax (some hospitals gross up; most don't).

"What's the certification differential?"

CCRN: $1-2/hr extra at most large systems. CMC, CSC, PCCN: similar. If you have certs, confirm they pay; if not, consider getting one — ROI is fast.

"What's the staffing model?"

Closed vs. open ICU? Intensivist-led? Resident-staffed? 24/7 in-house intensivist or call coverage? Affects autonomy, escalation comfort, and clinical complexity.

Red flag questions to listen for

• "We staff to assignment, not to acuity" → ratio likely too high for the patient population
• "We had a few RN turnover this year, recovering" → high turnover signal, ask details
• "You'll need to float to other units occasionally" → check how often + where (med-surg, OR, telemetry?)
• "We're moving toward team-based care" → can mean less RN autonomy + more UAP delegation
• "Mandatory overtime is rare but happens" → it happens. Confirm frequency.

Site visit + working interview tips

Many hospitals offer a 4-hour shadow shift on the unit before extending an offer. This is mutually evaluative — the unit is checking you, but you should also be evaluating them:

• Does the unit run smoothly or chaotically?
• How do RNs interact with intensivists, residents, RT, pharmacy?
• Are call lights answered quickly?
• How does the charge nurse manage assignments + admits?
• How does the team respond during a code or rapid response?
• Do RNs eat lunch, take breaks, leave on time?
• Talk to current staff candidly — "How long have you been here? Why?"
