ICU Nurse Study Resources

Core domains

Start with the domains panels probe most often, rehearsed as mechanism explanations you can deliver out loud.

• Shock physiology: recognition, categories, first interventions.
• Ventilator troubleshooting: pressures, waveforms, next checks.
• Vasoactive infusions: receptor logic, titration, perfusion endpoints.
• Cardiac assist devices: purpose, alarms, escalation triggers.

How to study efficiently

Run short case drills and force mechanism explanations out loud. If you can explain the why, you can survive follow-ups.

Prompt: your patient on norepinephrine stays hypotensive. Candidate: I check volume status, rhythm, and perfusion markers first. Follow-up: pressures still low after fluids. Candidate: I reassess vascular tone and cardiac output, then discuss adding vasopressin per protocol with the team. Follow-up: why vasopressin here? Candidate: it raises tone through a separate receptor path while I keep watching perfusion.
